Nokia stated that China Unicom had initially deployed the 7950 XRS into metro networks in six provinces - Beijing, Shandong, Jiangsu, Jiangxi, Inner Mongolia and Qinghai - and under the latest agreement planned to deploy it in an additional four provinces, namely Heilongjiang, Henan, Zhejiang and Hunan, to improve services for fixed and mobile broadband subscribers.

Pluribus introduces Netvisor-based Adaptive Cloud Fabric virtualised architecture

Pluribus Networks, developer of technology enabling software-defined networking (SDN) via its programmable, open source-based operating system Netvisor announced the next evolution of its SDN strategy with the introduction of the Adaptive Cloud Fabric virtualised architecture.

Based on the Netvisor network virtualisation software, the new Adaptive Cloud Fabric is designed to offer a simple, dynamic and secure approach to building a distributed network architecture with the capabilities of cloud-scale, elasticity and adaptability for the modern data centre.

The Pluribus Adaptive Cloud Fabric provides an optimised and resilient operating environment designed to address the requirements of enterprise and service providers with the need to support transaction-intensive applications. The fabric distributes intelligence, integrates a range of advanced network services, provides visibility of all traffic traversing the network and is designed to facilitate the transition to a software-defined data centre.

The Adaptive Cloud Fabric operates without a controller and is claimed to deliver a more dynamic and elastic network with the ability adapt to changing requirements and a range of deployment scenarios to help streamline operations, improve efficiency and lower costs.

The Adaptive Cloud Fabric can be deployed across the data centre or in specific racks, pods, server farms or hyper-converged infrastructure such as Nutanix, vSAN and VxRail. In addition, multiple geographically distributed data centres can be interconnected into a fabric over any WAN or dark fibre infrastructure. The dynamic architecture provides multi-terabit capacity with predictable latency and can support millions of concurrent connections.

Pluribus' Adaptive Cloud Fabric is based on the Netvisor software running on open networking switch hardware, offering a virtualised network OS (NOS) and providing a Layer 2 and 3 networking foundation, distributed fabric intelligence and virtualised switch hardware, similar to how VMware virtualises a bare metal server.

In addition, Netvisor vPort technology serves to extend intelligence and control to all connected endpoints, VMs, containers and mobile devices across the fabric, tracking the location, identity, policy and history for each endpoint and dynamically sharing the status to all member devices in real-time.

The fabric also features APIs that enable integration with automation tools such as Ansible and programming languages such as Python, plus integration with VMware vCenter for centralised automation of virtual application infrastructure and orchestration of physical and virtual resources and workloads.

Netvisor OS integrates telemetry for visibility across the fabric, allowing monitoring for 10, 25, 40 and 100 Gbit/s interfaces without the need for dedicated network probes. The Netvisor software can run on Open Compute Project (OCP), and Open Network Install Environment (ONIE) hardware-compliant switches, including from Dell EMC, Edgecore and Pluribus Freedom series network switches.

Big Switch enhances Big Cloud Fabric

Big Switch Networks, a supplier of next-generation data centre networking solutions, announced it has extended Big Cloud Fabric (BCF) container networking support to VMware vSphere integrated containers, building on the previously introduced multi-container networking support for Mesosphere DC/OS and Kubernetes container orchestration platforms, including Red Hat OpenShift container platform.

Big Switch noted that as demand for container technology grows in enterprise and service provider data centres, a next-generation networking architecture is required to handle the rapid lifecycle of container instantiation, elasticity and retirement. BCF uses SDN to provide a single 'logical switch' managed by a centralised controller, enabling simplified network operations, visibility and telemetry of containers and their hosts, and network automation for application and micro-services deployment.

vSphere integrated containers allow organisations to use existing infrastructure to run containerised apps together with traditional applications on the same infrastructure, as well as implement tools, policies and processes to manage containerised applications in production. With the enhanced BCF, customers gain the same benefits for networking infrastructure hosting a mix of traditional VM and containerised workloads.

In container environments, the Big Switch BCF controller enables physical network automation as well as providing greater visibility of container-to-container traffic across the network through integration with vSphere integrated containers.

Big Cloud Fabric is designed to offer an optimised networking fabric for multiple VMware solutions via a single point of integration. Within VMware environments, BCF connects with the VMware vCenter API to provide physical network automation and end-to-end visibility for vSphere. In addition, the BCF controller directly integrates into vCenter to help simplify and automate application deployments on its physical SDN fabric and physical networks.

This BCF integration allows the following aspects of the network to be automated, eliminating the need for intervention from VM or network administrator: automatic ESXi host connectivity with fabric using LAG/MLAG; automated Layer 2 network configuration; and automatic network policy migration for vMotion.

Integrated VMware visibility via BCF also helps network and virtualisation administrators to resolve cross-domain issues, while vSphere integrated containers provide enterprise container infrastructure to help IT teams run both traditional and containerised applications on a common platform. Combined with BCF, the same physical infrastructure can be logically provisioned and orchestrated in different VMware environments for workloads including vSphere, vSphere + NSX, vSphere + vSAN, VMware integrated OpenStack and vSphere integrated containers.


In addition, the scale-out architecture of BCF can accommodates growth in east-west traffic with the roll-out of micro-services.

Criterion Offers Support for CORD

Criterion Networks, a network transformation and solution integration company with a focus on supporting the adoption of SDN, NFV and the cloud, announced the availability of the Mysterious-Decision release of CORD (Central Office Re-architected as a Datacenter) on the Criterion SDCloud platform.

Criterion Networks stated that as enterprises and service providers move towards SDN/NFV deployment, it can provide an on-demand SDN/NFV solution environment. SDCloud Enterprise, Criterion's SaaS-based solution orchestration platform is designed to enable customers to bring up the SDN/NFV solution environment of their choice for development, evaluation and learning.

The cloud-based development and test environment, CORD-in-the-Cloud (CiTC), is designed to simplify the process of launching the SDCloud solution and allows for one touch provisioning of the components of CORD in an isolated, multi-node virtual environment. CiTC also offers a base platform to build more complex use cases such as Mobile CORD (M-CORD).

The company noted that reliably implementing complex test-beds such as CORD in a stable manner presents a challenge for developers. CiTC facilitates test-bed creation and is designed to help customers realise the potential of CORD. With all components of CORD instantiated by SDCloud, customers are able to validate configurations with different versions of the solution components, change controllers, orchestrators or the Open Stack VIM, which constitute key components of the CORD framework.

Criterion Networks, an early contributor to ON.Lab and ONF, provides CiTC for established use cases such as R-CORD and is used by ON.Lab for development purposes. It also offers complex solutions such as CiTC, OpenStack sandboxes with different SDN controllers and other OpenStack integrated SDN/NFV solutions, together with eLearning programs through the Criterion Networking Academy.

Criterion launched its SDCloud Platform in April 2016, offering a scalable on-demand cloud deployment and provisioning platform for evaluating SDN/NFV and OpenStack solutions. The platform initially provided support for Software Defined Data Center (SDDC) use-case solution.


In July last year, Criterion Network Labs, an independent network interoperability test facility, announced the launch of CNLabs SDN/NFV Alliance Program, intended to bring together SDN/NFV product vendors and end users to help ensure that SDN/NFV products meet the solution and production requirements of customers.

Google Builds Expresso SDN for Public Internet

"SDN is how we do networking… so what’s next?" asked Amin Vahdat, Fellow and Technical Lead for Networking at Google, at the opening of his keynote address at the Open Networking Summit in Santa Clara, California.

Google has been using SDN for years to manage its private B4 global WAN (interconnects data centers) and its Jupiter networks (inside its data centers, which have up to 100,000 servers and up to 1 Pb/s of aggregate bandwidth). Traffic on its private networks exceeds that on its public Internet backbone, and the growth rate is faster too. Google also relies on its Andromeda network functions virtualization platform as one of its pillars of SDN.

Google's next step is to introduce "Expresso" SDN for its public Internet backbone.  Expresson has been running on the Google network for the past two years and is currently routing about 20% of traffic to the Internet.

Essentially, Google Expresso SDN Peering takes a metro and global view across many routers to find optimal route for traffic delivery.  Whereas traditional, router-centric protocols take a connectivity-first approach with only local information, Vahdat said Expresso is able to optimize route selection in real-time by leveraging application signals across the metro or global infrastructure. One effect is to remove the logic and control of traffic management from individual boxes and make it network-centric.

Here is an architectural view of Google Expresso SDN:



Expresso sets the stage for the next decade in networking, said Vahdat, where the Internet must deliver improvements in scale, agility, jitter, isolation and availability. Google sees each of these attributes as necessary for the next wave of serverless computing.

Packet Design and NEC/Netcracker Form Alliance

Packet Design, a provider of route analytics designed to enhance network availability and performance, and NEC/Netcracker announced they have partnered to help service providers implement software-defined networking (SDN) applications to improve service quality and reduce costs.

Citing the growing number of SDN use cases, ranging from rapid services activation to automated path restoration, Packet Design stated that its real-time analytics technology, combined with NEC/Netcracker's Transport SDN solution that includes transport SDN controller and service orchestration solutions, can help to enable these processes in operators' commercial networks.

Packet Design's real-time analytics provide a foundation for emerging WAN-SDN (also termed carrier or service provider SDN) applications by correlating control plane, traffic and performance analytics data. This information helps operators to understand how routing events and failures affect the path and performance of services.

The real-time and historical intelligence provided by the company's solution also allows predictive analytics to accurately assess application requests for network resources and the best means of provisioning them.

Combined with NEC/Netcracker's Transport SDN solution, this analytics data can enable intelligent automation and help operators to manage both planned and unexpected changes, as well as ensure network service delivery. Additionally, Packet Design's RESTful APIs support programmatic access to microservices for the creation of custom SDN applications.

Under the new agreement, Packet Design is joining NEC/Netcracker's Ecosystem 2.0 program. Packet Design and NEC/Netcracker are currently certifying the interoperability of their products and preparing joint go-to-market programs and will jointly market and sell the combined SDN solutions.

Previously, in November 2016 Packet Design announced it had joined Ciena's Blue Orbit program, designed to facilitate multi-vendor SDN and NFV deployments, to support the delivery of multi-layer SDN management and orchestration capabilities. Through the partnership the two companies planned to integrate Packet Design's IP/MPLS analytics and WAN-SDN management and orchestration (MANO) platform with the Ciena Blue Planet software for multi-domain orchestration and provisioning.

Infinera's Instant Network Delivers Software Defined Capacity for Optical Transport

Infinera introduced Instant Network capabilities for delivering software defined capacity (SDC) for cloud scale networks.

The new capabilities extend Infinera Instant Bandwidth, which provides software activation of service-ready optical capacity in a few hours on networks powered by its DTN-X platform and equipped with its unique photonic integrated circuits (PICs). Infinera introduced Instant Bandwidth in 2012 and more than 70 Service Providers are now using it. In 2015, Infinera introduced Time-based Instant Bandwidth in 2015, enabling software activation of bandwidth licenses for a limited duration.

Instant Network adds Bandwidth License Pools, Moveable Licenses and Automated Capacity Engineering (ACE). It also extends SDC to new Infinera platforms, which support flexible grid and sliceable 2.4 terabit super-channels powered by the Infinera Infinite Capacity Engine.

Highlights:

  • Bandwidth License Pools: The new Bandwidth License Pool functionality enables service providers to activate capacity at the same time as an invoice is issued for that capacity, reducing capital expenditures for idle capacity. This new capability enables capacity to be deployed in minutes, while previously, service providers would purchase a license before the capacity was software-activated, which resulted in deployment taking a few hours.
  • Moveable Licenses: New Movable Licenses enable service providers to use software to move bandwidth licenses across the network as traffic conditions change or fiber cuts occur. Previously, licenses were fixed to a specific line module or platform. Moveable licenses reduce capital expenses by reducing idle capacity provisioned specifically for network resiliency and increase agility when responding to customer demands for new services.
  • Automated Capacity Engineering (ACE): The new ACE application takes previously manual offline route and capacity planning processes and implements those algorithms in a microservices-based path computation element (PCE). ACE understands optical impairments and computes optimal Layer 0 routes between nodes across multiple paths, including automatic routing and wavelength assignment with multiple path constraints such as traffic engineering cost, distance and latency.

Infinera Instant Network capabilities are planned across the Infinera DNA software and the Xceed Software Suite. Instant Network Bandwidth License Pool and Moveable Licenses are available now. ACE is planned for 2018.

Infinera said its Instant Network  enables service providers to automate optical capacity engineering and scale optical capacity in minutes by using Infinera’s Xceed and Digital Node Administrator (DNA) software.  It also sets a foundation for cognitive networking, which includes advanced analytics, machine learning from streams of network telemetry data, autonomous operation of routine tasks, predictive analysis of network problems before they occur and proactive recommendations for network optimization to further reduce operational expense and improve service reliability.

“Infinera is committed to providing our customers with innovative solutions to help them win in the markets they serve,” said Dr. Dave Welch, Infinera co-founder and president. “Software defined capacity is a requirement to realize the benefits envisioned by SDN and network functions virtualization. Infinera Instant Network extends our success with Instant Bandwidth, leading the market for software defined capacity while lighting the way to cognitive networking.”

Fujitsu Labs Unveils Tech for Multi-location Virtual Networks

Fujitsu Laboratories and Fujitsu Laboratories of America have announced the development of technology designed to simplify the delivery and operation of virtual network infrastructures that span multiple clouds and corporate networks.

The company noted that using conventional technology it is possible to build virtual network infrastructure within an individual cloud or corporate location utilising software defined networking (SDN) technology. However, virtual network infrastructure spanning multiple clouds and locations can require a different set-up for each cloud and location and manual configuration to connect each element of the IT infrastructure.

To address this issue, Fujitsu has developed software technology that abstracts the structural elements of networks in the IT infrastructure and which can support design, build, management and operation across multiple IT infrastructures. The company claims the technology can enable virtual network infrastructure to be built in one-tenth the time required with conventional technology for a virtual network infrastructure encompassing one cloud and a location with a few dozen devices.

The now solution developed by Fujitsu Labs and Fujitsu Labs of America functions by abstracting the structural elements of IT infrastructure to enable automated design and deployment of IT infrastructure that extends across multiple locations, while managing and operating the system as a single network infrastructure.

The new technology features elements as follows:

1. IT infrastructure abstraction via modelling of structural elements of IT infrastructure using logical software components to enable key features such as element configuration and operational status monitoring, allowing users to automatically build and operate virtual network infrastructures across multiple instances of IT infrastructure.

2. Virtual network function automatic supplemental technology to support the conversion from a logical to a virtual network infrastructure through deriving the designer's plans from the connection status of the logical network, automatically supplementing network functions by checking the connections between objects at different levels, such as IT infrastructure, subnets and nodes located at each end of a connection.

Fujitsu Labs stated that using the technology it is possible, for example, for a single engineer to design and configure a virtual infrastructure across one cloud and a location with a dozens of devices within one day. In addition, when migrating enterprise systems to the cloud it is possible to rapidly implement a project by performing operations on the logical network, or when setting up a network at multiple locations, by designing one logical network and then implementing a virtual network at each location.

Fujitsu Labs plan to continue development of additional functions for lifecycle management in logical networks using the technology, with the aim that Fujitsu will be able to provide sales as a network management function for enterprise users of cloud services after fiscal 2017.

Juniper Networks announced at MWC 2017 that it has been selected as a Vodafone Global Approved Vendor for its Contrail Networking software-defined networking (SDN) solution, which will help the operator to develop new, user-driven and flexible business services for customers.

Juniper noted that Contrail Networking is an open, flexible SDN solution designed to provide automation and orchestration for scalable virtual networks, which can help operators such as Vodafone to leverage the cloud to deliver services, enhance business agility and increase revenue.

During MWC, Juniper hosted a presentation of VPN+ as a showcase Vodafone's multi-vendor mobile VPN services portfolio, which constitutes a key part of the Vodafone Ocean Transformation program to virtualise its networks launched last year.

The demonstration featured VPN+ use cases including SD-WAN, service chaining, on-demand services, virtual cloud-hosted services and universal, virtualised CPE. VPN+ services are designed to leverage a customer portal that allows users to select, change and provision services.

Separately, Juniper announced at MWC the availability of a carrier-grade cloud solution designed to allow the rapid implementation of mobile subscriber service virtual networks functions (VNFs). The solution combines Affirmed Networks Mobile Content Cloud virtualised evolved packet core solution (vEPC) with Juniper's Contrail Networking solution and the Netronome Agilio SmartNICs.

The solution integrates the Juniper Contrail Networking SDN solution with Affirmed Networks MCC vEPC offering probe, analytics, WiFi gateways (TWAG, ePDG), Gi-LAN services, service orchestration and IoT services, and Netronome's Agilio SmartNIC 10/25/40 Gigabit Ethernet platforms that offloads virtual switch and router datapath processing for networking functions to reduce CPU load.

ECOMP and OPEN-O to Become ONAP

The open source ECOMP project, which AT&T recently turned over to the Linux Foundation, and Open Orchestrator Project (OPEN-O), which is also managed by the Linux Foundation, will be merged to create the new Open Network Automation Platform (ONAP) Project.

ONAP will allow end users to automate, design, orchestrate, and manage services and virtual functions. Its goal is to provide a harmonized and comprehensive framework for real-time, policy-driven software automation of virtual network functions that will enable software, network, IT and cloud providers and developers to rapidly create new services.

The Linux Foundation said that by consolidating member resources, ONAP is well positioned to deliver a unified architecture and implementation, with an open standards upstream focus, faster than any one project could on its own.

Founding Platinum members of ONAP include Amdocs, AT&T, Bell Canada, China Mobile, China Telecom, Cisco, Ericsson, GigaSpaces, Huawei, IBM, Intel, Nokia, Orange, Tech Mahindra, VMware and ZTE. Silver members of ONAP are ARM, BOCO Inter-Telecom, Canonical, China Unicom, Cloudbase Solutions, Metaswitch and Raisecom.

“By combining two of the largest open source networking initiatives, the community is able to take advantage of the best architectural components of both projects,” said Jim Zemlin, Executive Director of The Linux Foundation. “We’re excited to see the industry coalesce around ONAP with this unprecedented merger. Such a broad effort and investment will expedite our vision to deliver an open platform for network automation.”

The Linux Foundation will establish a governance and membership structure for ONAP to nurture a vibrant technical community.

“AT&T is excited to be working with a larger team on the future, open source network operating system for SDN automation. Creating a combined team of the initial open source ECOMP members with existing OPEN-O members bodes well for the project’s success. I want to thank the people at CMCC and Huawei, along with Jim Zemlin and Arpit Joshipura at The Linux Foundation who worked so hard with us to make this happen. We expect more consolidation in this space, and we expect many more service providers and other technology leaders to join us in this important work, which benefits the entire industry,” stated Chris Rice, SVP of Domain 2.0 Architecture and Design at AT&T.

“It is well accepted that SDN/NFV plays a key role to the carrier transformation, where automation of management and orchestration is one of the most critical enablers. Hence China Mobile has long been investing resources in the orchestrator development, and launched OPEN-O open source project with partners. In order to cohere efforts, to avoid fragmentation, and to accelerate the transformation of operators, China Mobile, AT&T and The Linux Foundation, finally reached consensus after several rounds of discussion. We are pleased to embrace the birth of the new project ONAP. It is our firm belief that, as the world's two largest telecom operators, the close collaboration in ONAP between China Mobile and AT&T, will accelerate the carrier network evolution with a strong impact on the industry globally. We sincerely hope that more industry partners would join hands with us in ONAP to promote industrial prosperity,” stated Madam Yang Zhiqiang, Deputy General Manager, China Mobile Research Institute.

Radisys Delivers FlowEngine TDE-2000 for SDN + NFV

Radisys announced the delivery of its FlowEngine TDE-2000 carrier-grade open network switch for SDN and NFV.

Radisys said its new 1-RU FlowEngine TDE-2000 platform delivers robust Layer 2 through 5 traffic classification and distribution with very high throughput and low latency. The platform is the new flagship offering in Radisys’ FlowEngine TDE portfolio, leveraging programmable network processors which makes it easy to add new features moving forward. FlowEngine TDE-2000 is designed to open standards, and brings together switching, load balancing, security and routing functionality under open policy control. The FlowEngine TDE-2000 also enables Service Function Chaining (SFC) functionality for distribution of traffic flows through a programmable sequence of virtualized network functions (VNFs).

“As service providers migrate from legacy networks to new virtualized telco data centers, they require a programmable, flexible and scalable traffic distribution platform that meets price/performance targets,” said Bryan Sadowski, vice president, FlowEngine and DCEngine, Radisys. “Our FlowEngine TDE-2000 delivers the highest density in the market in a 1RU platform and is readily deployable in multiple architectures as a standalone switch, Leaf/ToR, or Spine/EOR switching fabrics. The FlowEngine TDE-2000 also can be deployed as an NFVI solution in our DCEngine platform. The powerful combination of the TDE-2000 pre-integrated with our updated FlowEngine software enables our customers to accelerate their SDN and NFV deployments.”

“When Radisys launched its FlowEngine TDE portfolio, we reviewed how the platform met 16 network virtualization requirements very well.
