Overture Adds Carrier Ethernet VNF and Service Intelligence

Overture Networks introduced its Ensemble Carrier Ethernet (ECE) Virtual Network Function (VNF) -- the first such hardware-agnostic Carrier Ethernet VNF, delivering the same Carrier Ethernet 2.0 functionality of a physical Ethernet Access Device without being tied to proprietary, purpose built hardware.

Overture said its ECE VNF software can run on any Intel-based server. For hardened environments, the Overture 65vSE can host the ECE and multiple other VNFs. This hardware-agnostic approach provides service providers with the ability to instantly deploy new, on-demand applications in a CO, data center, or customer premise, simplifying operations and driving new service innovation. As a software-based solution, the ECE VNF can easily scale services as needed, with line-rate performance up to 10GigE. It also enables an optimized NFV model where the virtual network functions can be placed wherever the service provider chooses; the service edge, a central location, or both.

“Our customers clearly want to transition their networks into agile, automated, open environments that will drive dramatic costs reductions and accelerate their service delivery,” said Mike Aquino, president and CEO, Overture “the introduction of the industry’s first true Carrier Ethernet Virtual Network Function is a milestone achievement in the advancement of NFV from the lab to field trials.  It demonstrates our commitment to an evolving open ecosystem which ultimately helps our customers maximize both capital and operational efficiencies, while accelerating the pace of new revenue-generating.”

ECE joins the company’s already released Ensemble Service Orchestrator (ESO) and Ensemble Network Controller (ENC), as part of Overture's growing Ensemble Open Services Architecture portfolio.

Overture is also introducing its Ensemble Service Intelligence (ESI), which leverages big data technologies and applies advanced analytics in an open system to provide actionable intelligence for service orchestration. ESI stores and correlates data from virtual and physical network components, as well as from existing performance management, EMS and other management systems. ESI enhances automated orchestration across a multi-vendor NFV environment with features such as service lifecycle management, policy-based auto-scaling and multi-level service verification and diagnostics. It comes with an initial suite of service intelligence applications that provide full service lifecycle history, as well as the capability to monitor network VNF performance to ensure customer SLAs are met.

Overture said its new ESI provides a simplified way to achieve OSS integration by bridging NFV with legacy systems, while its open architecture allows further application development.

Overture Intros 8-Slot 6500 Service Aggregation/Switching Platform

Overture introduced an 8-slot version of its 6500 service aggregation and switching platform, which can be used to deliver Carrier Ethernet over any access method, including fiber, E-Access, copper, SONET, and TDM, with full resiliency.

The 6500 is a key component of Overture’s Ensemble Open Services Architecture (Ensemble OSA), an open platform for service automation and network virtualization. Ensemble orchestration and control software activates the Overture 6500 to build connectivity in the OSA between end customers and virtualized network functions.

The newly introduced 6508 8-slot chassis joins the 3-slot 6504 released in 2013 and uses the same interface modules and processors. The 6508 chassis can serve combinations of up to 192 1GigE and 18 10GigE optical, 768 Ethernet over Copper pairs, 32 Ethernet over SONET, 2688 Ethernet over DS1s from a single 19” chassis.

Overture also noted its latest 6500 software release adds cross-card bonding capabilities for copper and TDM groups to the 6500’s existing cross-card link aggregation and cross-card G.8032v2 Ethernet ring capabilities. Cross-card bonding improves resiliency and eliminates the need for service providers to move pairs from one card to another when addressing pair growth. The 6500 cross-card bonding approach consumes no additional card slots and requires no dedicated switching cards, which means service providers don’t pay a premium for high availability and easy growth.

“The latest enhancements to the 6500, together with our Ensemble OSA, demonstrates how Overture is helping create a fundamentally new approach for service creation, activation and assurance,” said Brian van Voorhis, Senior Product Manager, Overture. “As operators begin to realize the benefits of SDN and NFV integration, we are committed to providing a ubiquitous Carrier Ethernet foundation at the metro service edge so that our customers achieve unmatched service agility and operational efficiency today and for the future.”

Overture's 65vSE Micro Server Runs VNF at Service Edge

Overture introduced an open, Carrier Ethernet platform that enables virtualized network functions to be controlled dynamically at the service edge.

The 65 Virtual Service Edge (65vSE), which is part of the Overture 65 product family, is a carrier-grade platform based on Intel x86 micro-server technology.  It comes comes pre-loaded with Overture’s CE2.0 Ethernet Access Device (EAD) software and is designed to dynamically host multiple third party virtual network functions (VNFs). Additionally, the Overture 65vSE supports multiple wireline and wireless connections to the WAN, allowing access to all end customer locations.

The new platform is enabled the company's Ensemble Open Service Architecture (OSA) for software-defined services at the metro service edge. As an integrated platform for Carrier Ethernet access and virtualization, the Overture 65vSE enables virtual network functions to be turned up, turned down, expanded and removed dynamically at the service edge.

Overture previously introduced a centralized model for hosting virtual network functions in data centers, points of presence, and central offices. The new 65vSE enables these virtual network functions at the service edge.  Overture said this provides another choice in network architecture that may enable faster time to market for new service revenue and customer adoption. For instance, there are times when the security, latency, or other requirements of specific functions dictate optimal placement is on the customer premise, or service edge.

“Openness directly benefits our customers and positions them for growth and success. We have combined our Carrier Ethernet expertise with the first truly open platform for hosting best-of-breed network functions from third party developers.” said Prayson Pate, CTO and senior vice president of engineering, Overture. “The 65vSE along with the other components of Ensemble OSA and our Carrier Ethernet portfolio, together bring the speed and agility benefits of the cloud to the metro service edge.”

http://www.overturenetworks.com/products/overture-65vSE

In April 2014, Overture stepped up its game in software defined networking (SDN) and network functions virtualization (NFV) with the commercial release of its Ensemble Service Orchestrator (ESO) and Ensemble Network Controller (ENC), two key pieces of its open architecture for service automation.

Overture said its goal is to bring together open automation and management of both the physical Carrier Ethernet and virtual infrastructure.  The will use open APIs for deployment into third-party infrastructure.any service provider architecture, Ensemble Service Orchestrator and Ensemble Network Controller may be deployed together as a system or integrated independently.

·       The Ensemble Service Orchestrator is an open, extensible carrier-class NFV service lifecycle management and orchestration system that coordinates virtual resources and physical network elements to create, activate and assure services using one or more virtual network functions. ESO uses the OpenStack™ cloud controller – bundled with ESO – to manage the virtual compute environment, including virtual machines, virtual switches and top-of-rack datacenter switches. For management of the physical wide area network traffic flows, ESO leverages Overture’s Ensemble Network Controller but can also be integrated with other third-party network controllers.
·       The Ensemble Network Controller is a service-aware network controller and management system for the Carrier Ethernet metro service edge. With native support for all Overture network elements, ENC is extensible to support third-party network elements and automates service creation, service activation, device detection, fault management and performance monitoring. By presenting a complete network picture, ENC helps service providers add new services and virtualized network functions without compromising existing network operations.

Blueprint: NFV, SDN and Carrier Ethernet Make Progress

By Prayson Pate, Chief Technology Officer and SVP of R&D at Overture

Network Functions Virtualization (NFV) and Software Defined Networking (SDN) have been getting a lot of airplay recently, and everyone is coming out with their SDN or NFV stories.  With all the airplay on Network Functions Virtualization (NFV) and Software Defined Networking (SDN), some critically important information is getting lost in the hype. NFV and SDN are not standalone technologies, and they are not sufficient for building commercial, revenue-generating services. What about the metro access network that is used to reach customers? It is Carrier Ethernet that has become the foundation on top of which all next generation services are being built, and which must team with SDN and NFV.  After all, you can’t virtualize pipes.
Each of these three technologies (NFV, SDN and Carrier Ethernet) is powerful in its own right.  What are the keys to their individual success, and how can they be combined?

Ethernet – Heart of the Access Network and the Data Center

Carrier Ethernet got its start as a cost-effective technology based on the native format for enterprise networks.  The Metro Ethernet Forum (MEF) created a standard set of definitions and interfaces to facilitate the use of Ethernet, both as a service and as infrastructure.  These definitions were initially covered by tests specified in the MEF 9 and MEF 14 standards.  Later, this standardization was expanded into CE 2.0, with increased capabilities for management, multiple service classes and features that supported interconnect between service providers.

Ethernet is also the core of cloud/datacenter connectivity.  Modern data centers are built upon a framework of Ethernet switches, both physical and virtual, and almost all data center elements have Ethernet interfaces. Going forward, Ethernet promises continuing growth, both in speed and capabilities.

Carrier Ethernet has become the foundation for all future networking services in the cloud, whether at the edge of the network or in the data center.  While necessary, Carrier Ethernet is not sufficient for constructing modern services.  The evolution of services at the edge of the network will require harmony between Carrier Ethernet, SDN and NFV.

NFV – Bringing the Cloud to the Network

NFV is a concept introduced by a group of leading service providers.  The idea is to achieve the benefits of the modern datacenter and to bring them to the communications network: virtualization, low cost standardized hardware, ecosystems of software components coupled by open APIs, and rapid development and deployment of services, as shown in this figure.




Service providers have embraced NFV because it promises lower costs and higher revenues through service innovation.  In particular, NFV offers the following:

  • Service providers will be able to define and deploy new services without installing or replacing network elements.  Upgrades will take the form of installing new VMs, which is a much lower impact process than replacing physical appliances.
  • Service providers will be able to define new services independently from equipment providers.  They will be able to construct a new service from virtualized network functions provided by independent software vendors ISVs) or even create them internally.
  • Finally, service providers will be able to unite the connect, compute and storage components.  Doing so will expand the scope of the types of services that can be offered today.  For example, with NFV, it is possible to couple storage utilities such as Content Delivery Networks (CDN) with private networking and cloud in order to enable applications like online education.

SDN – Control and Automation

In contrast to the service provider push for NFV, SDN came out of the universities and found its way into the modern data center.  SDN provides improvements in how cloud components can be configured, connected and operated.  SDN brings network operators a model for modernizing how they control their networks, including a movement from closed proprietary systems.  As with NFV, open ecosystems of providers and components are an essential part of SDN.

Much of the early promotion of SDN has been on the use of the OpenFlow protocol used to program the forwarding behavior of the network in a standard and open way.  By deploying OpenFlow-enabled devices, a service provider could develop new services, and even new protocols, without upgrading the network.  This OpenFlow-centric view of SDN has been hampered by its limited support of equipment in the network.  Even so, it does hold great promise for the future. In addition, alternatives such as NETCONF and RESTFUL interfaces may also be paths through which to gain the benefits of SDN.

Combining NFV, SDN and Ethernet

NFV, SDN and Ethernet are all powerful components in their own right.  This figure shows how they are being combined.


  • Ethernet and SDN currently co-exist in the data center, especially inside virtual switches (vSwitches).  Today’s vSwitches are controllable by OpenFlow to provide interconnection of virtual machines.
  • SDN and NFV currently intersect in the Central Office (CO), which is the next generation data center.  As such, it is a ripe target for early deployments of NFV with SDN being used for control.
  • NFV and Carrier Ethernet can be combined to provide some interesting applications, such as Virtual Service Edge (VSE).  VSE is the replacement of dedicated customer-located appliances (e.g. routers and firewalls) with software-based applications running on a standard compute platform and connected via Carrier Ethernet to the wide area network.

What Changes will be Required in Carrier Ethernet?

Combining all three technologies will get us to the sweet spot for future innovation.  However, doing so will require continued evolution of Carrier Ethernet, which has been constantly growing and changing to meet the evolving needs of its users. What are the next changes that are needed?

Better Coupling with SDN

As described above, vSwitches currently provide a virtual way to connect cloud components under the control of OpenFlow.  However, OpenFlow provides a degree of arbitrary flow identification that is often not needed, and which is not compatible with much of the deployed base of equipment.  For example, OpenFlow can define a flow based on parameters such as MAC addresses and QoS markings.  A simpler forwarding model and standard focused on Carrier Ethernet virtual connections would facilitate the use of SDN principles with existing infrastructure. This leads to the next area for growth.

Simpler Standardized Interfaces

Because OpenFlow can be used to control arbitrary flows, its control protocol must be equally flexible.  What is needed is a simpler model for an API and data structure that matches current capabilities.  The MEF has an opportunity to drive innovation and consistency related to controlling Carrier Ethernet infrastructure.  In particular, the definition of a schema to match the current CE 2.0 capabilities would be very useful.

Definition of New Services to Support Cloud

Despite its power, Carrier Ethernet has some limitations, especially with respect to VLAN and MAC scaling.  These limits have driven work on new protocols for network virtualization such as VxLAN and NVGRE.  These technologies allow the construction of overlay networks to decouple the VLANs needed by virtual machines from those used to provide the underlying connections.  There is still disagreement, however, about exactly what new capabilities are needed, causing divergence in how network virtualization is being implemented.

Carrier Class Orchestration

In the data center, orchestration refers to automated provisioning, coordination and management of physical and virtual resources.  In the data center, resources are homogeneous and fungible, and we can assume fat pipes for connection.  This is not the case for application of SDN and NFV to the access network using Carrier Ethernet.  We need orchestration that can take into account such parameters as cost and availability of resources, location and latency, and available bandwidth.  In addition, elasticity and multi-tenancy are key attributes of a carrier-class orchestrator.

Summary

By combining the powerful technologies of NFV, SDN and Carrier Ethernet, service providers will be able to reach their goals of modernizing their networks, cutting costs and, most importantly, accelerating the creation and deployment of lucrative new services.  Continued innovation is required for Carrier Ethernet to be able to support this evolution.  Adding new capabilities will enable efficient expansion of new services beyond the data center into the Carrier Ethernet-powered metro service edge.

Bringing the Power of the Cloud to the Metro Edge

By Prayson Pate, Chief Technologist, Overture

Cloud technology has changed how users and developers think about applications.  Why buy servers and maintain software if you can pay per use?  Why build applications from scratch if you can make use of existing frameworks and software?  Why configure web servers if all you want to do is make a simple web page? Developers and users are now empowered to think about the higher-level applications and services, rather than the underlying machinery.



So far, this re-thinking has been limited to end-user applications housed in data centers.  The network connection between the data center and the end user has been left out of the equation.  However, service providers must find ways to couple high-performance networks with cloud and content providers in order to participate in current revenue streams.  Why have they not yet applied cloud technology to accomplish this?  In short, the network is complicated, especially at the metro edge.

While data centers are closed systems, where devices tend to be very similar and operated by the same entity, the metro edge is the “Wild West” of disparate technologies and myriad operators.  Given this complexity, how can cloud technology simplify how we deploy and manage the metro edge? How can they simplify, accelerate and build services that traverse the edge?  The answer involves virtualization, openness, focusing on services and thinking differently.

Virtualization

The key points of virtualization are abstraction and separation/layering. 
  • Abstraction - According to Wikipedia, “Abstractions may be formed by reducing the information content of a concept or an observable phenomenon, typically to retain only information which is relevant for a particular purpose.”
  • Separation/Layering - The notion of layering allows a well-defined interface, which can then be used to separate functions.  Separation lets us move functions to where they make the most sense.
How can virtualization be applied to the metro edge?. The Metro Ethernet Forum has identified the virtual Network Interface Device (vNID) Service as a case where virtualization would be beneficial and is within reach. Today, when one service provider accesses a customer via Carrier Ethernet using the facilities of a second access provider, it is likely that both providers deploy a NID.  With the vNID service only the access provider would deploy a NID, and the end-to-end service provider would access aspects of the NID as if they had their own NID (i.e. virtualization is used to present the appearance of two NIDs when only one physical NID is present).  This reduces the expense of deploying Ethernet service, while maintaining end user service assurance.

Network Function Virtualization (NFV) is another way that virtualization can be applied to the metro edge.  NFV is an initiative driven by an international group of leading service providers to lower costs and simplify networks.  NFV replaces purpose-built network devices with software applications running in a standard server.

Examples include:
  •  Managed routing: Today service providers use routers deployed at the customer site.. In particular, RFC 2547 Layer 3 VPNs are built using this approach.  This adds cost and complexity to the deployment of the services.  NVF provides the means to simplify the CPE (Customer Premise Equipment) by moving the routing protocol from the CPE into the network.  Now, value-added services such as managed routers and Layer 3 VPNs can be added on demand without changing the CPE.
  • Service assurance: Network Interface Devices (NIDs) are deployed at customer sites to facilitate measurement of service parameters using Service OAM (Operation, Assurance and Maintenance).  This adds cost because configuration of SOAM is a nightmare in today’s network.  NFV could apply abstraction to the NID and its MEGs (Maintenance Entity Groups), MIPs (MEG Intermediate Points) and MEPs (MEG End Points), and support the creation of applications to configure these functions.  The result would allow back office systems to treat service assurance as a utility, monitoring how the service is performing against its SLA (Service Level Agreement).
  • Managed security: Today, managed security applications are implemented either in dedicated hardware at the customer site or in servers at central offices.  Network hardware could provide some basic filtering and capture capabilities enabling complex aspects of these applications (such as policy definition, storage and distribution) to be moved to a separate application.
  • Analytics:   For service providers, the majority of analytical data is generated in the edge of the network, but gathering it may require a dedicated appliance.  Each service provider also has a different view of what data is important, as well as how it should be packaged.  The NFV model provides a means to limit the network hardware to collecting basic data and moving the processing to an offboard server. 
These applications are prime candidates for applying the principles of NFV, although concerns about reliability and environmental compatibility remain.  In addition, new requirements will be placed on network equipment. Effective network elements won’t be truly “dumb”.  The key is to maintain essential physical and data processing elements in a carrier-grade product, while moving many value-added functions into commercial-grade hardware, controlled by software in an open fashion. 

Openness

Having worked in the embedded software business for a long time, I know the skills required are specialized and uncommon.  What’s more, the compute and storage resources are constrained inside a network element, and the tools for embedded development are limited.  Any change to the software involves a large-scale and expensive download and upgrade cycle, possibly requiring a service outage.   

Development of cloud-style applications is quite different.  There is a large pool of talented software developers, compute and storage resources are plentiful and inexpensive, and development tools are sophisticated.  Since the software is usually running in a replicated server in a data center, upgrades are easily managed and can easily be undone. 

A critical aspect of cloud development is the use of applications developed using open interfaces and standard protocols. Cloud-style software facilitates code reuse and construction of large systems composed of multiple smaller pieces.  Interoperability is achieved through well-defined Application Programming Interfaces (APIs) that support interaction between systems at a black box level.

Open cloud-style applications can be developed more quickly and less expensively than embedded applications.  And, the open and extensible nature of cloud-style applications means consumers of these applications can themselves build larger applications that leverage and extend the base capabilities. 

Services, Service, Services

Applying cloud technology to the metro edge of the network will require changes in how service providers create, activate, and assure services. 


Service creation – Replacing complexity with a simple programming model, schema, and tools drastically reduces development time and cost of new features.  Reducing the cost and time to develop new services will let a service provider be more responsive to customers and market trends.. 

Service activation – Key to improving the speed and accuracy of service activation is increasing the use of automation.  Cloud-based technologies enable such automation by tying together relevant systems, providing an efficient development environment to deliver such benefits as:
  •  Zero-touch commissioning – Enabling a technician to install a device straight from the box, without need for local configuration.
  • Flow-through provisioning – When an order goes in for a service, flow-through provisioning automatically propagates the needed changes down to relevant network elements.
  • Instantiation of virtual appliances – Turning up services such as routing, firewall, security and VPN without installing new physical equipment.
  • Network optimization – As services are turned up and down, available capacity in the network changes.  Automating network optimization based on changes maximizes use of network resources. 

Service assurance – Ethernet Service OAM (SOAM) is the preferred, but inherently difficult, way to measure key SLA parameters such as packet loss, latency and latency variation.  . Service providers must also make provision for handling hard faults such as power, equipment or facility failures, as well as degradations signaled by Threshold Crossing Alarms.  Finally, there must be an efficient way to diagnose, sectionalize, and repair faults when they occur.  All of this is handled today using a variety of disparate and isolated tools.  What is needed is an efficient way to tie them together to achieve benefits such as automated configuration, proactive performance reporting, and automatic fault isolation.

Thinking Differently

The changes discussed above are large, but even bigger is the need to think differently.
  • People Are Mobile; Services Should Be Too: We need to consider issues like authentication, security, peering, replication, policy, and multiple platforms when considering how to build services.  Doing so is consistent with cloud-style development models and will support the creation of ubiquitous services.
  • Services, Not Pipes: Service providers must find ways to couple their high-performance networks with cloud and content providers in order to participate in current revenue streams – more focus on the end service or application the user is buying.
  • Roles and Systems, Not Boxes: Stop thinking about installing nodes in a network and start thinking about enabling services whose elements play various roles but which can be instantiated both in network elements as well as using cloud resources.
  • People Are Bad At Being Robots: People are inefficient at handling repetitive and mundane tasks. Applying cloud technology will help define new solutions to automate processes, which, in turn, will lead to greater efficiency by allowing people to focus on their creativity and problem solving skills.
  • Building for Today, Anticipating Tomorrow: The cloud has enabled a whole new generation of applications and services that were not envisioned by the builders of the first data centers.  As Jason Kleeh of Brocade noted, “the best app is the one that we haven't thought of yet.” 

Summary

We have an opportunity to enable the next generation of services by applying cloud technology to the Metro Edge of the network.  Doing so will require applying cloud technology and the supporting technologies of SDN and NFV.  This is a big change, but the benefits will be even larger.
