Broadcom Targets Virtual Customer Premise Equipment

Broadcom introduced a system-on-a-chip (SoC) for the virtual customer premise equipment (vCPE) market.

Broadcom’s BCM88312 is an integrated and programmable device that can be connected to the operator's network to deliver vCPE services.  It can be managed over OpenFlow, based on Broadcom's OpenFlow-Data Plane Abstraction (OF-DPA) layer framework, thereby extending OF-DPA from the infrastructure core all the way to the business CPE access.

By offering this remote management and virtualization capability, Broadcom said network operators will gain the ability to decouple services from the physical hardware and run them on standard compute infrastructure, thus facilitating faster time-to-market and enabling customers to customize their equipment based on evolving requirements.

"One of the greatest challenges facing service providers is how to offer new services to their business customers rapidly and more cost effectively," said Ed Redmond, Broadcom Vice President, Compute and Connectivity Group. "By decoupling service delivery and activation from the physical infrastructure, Broadcom's integrated and programmable device enables carriers to turn-up services as virtual network functions (VNFs) without the need for manual provisioning and expensive truck rolls.”

Key features:

  • Scalable, Integrated and Programmable
  • Integrated Dual Cortex A9 cores @ 1.2GHZ
  • Integrated 8-port GE Switch, Serdes, and copper PHYs
  • Programmable Processor Forwarding Engine

  • In March 2014, Broadcom first announced its OpenFlow Data Plane Abstraction (OF-DPA) v1.0 specification, software and API -- an openly published implementation of physical switch hardware pipeline abstraction for the Open Networking Foundation's (ONF) OpenFlow 1.3.1 Switch. The OF-DPA v1.0 specification, software and API can be used to implement network virtualization, multi-tenant networks and traffic engineering with higher scale and performance.  The software defines a pipeline that contains multiple tables, each table containing multiple flow entries. The OpenFlow pipeline processing defines how packets interact with these tables. The OF-DPA v1.0 physical switch hardware pipeline abstraction is an implementation of the OpenFlow 1.3.1 Switch optimized for Broadcom StrataXGS Ethernet Switch devices.


Brocade to Acquire Connectem for LTE virtual Evolved Packet Core

Brocade has agreed to acquire Connectem, a start-up based in Santa Clara, California developing an LTE virtual Evolved Packet Core (vEPC) solution.  Financial terms were not disclosed.

Connectem, which was founded in 2011, has been pursuing an overlay strategy for its Virtualized LTE Evolved Packet Core (EPC), betting that mobile operators will implement its NFV-powered solution first for specific business applications while continuing with their current LTE infrastructure rollouts.  Connectem's solution leverages cloud computing, network virtualization, and software networking technologies to deliver higher scale and efficiency on industry-standard x86-based servers. Connectem software focuses on mapping mobile workloads to cloud resources, eliminating the constraints of physical equipment boundaries yet still maintaining the capablity to integrate with traditional node-based EPC architectures.

Brocade said the acquisition of Connectem extends its portfolion in software networking and virtualized network functions, by enabling service providers and enterprises to offer ubiquitous connectivity between mobile and IoT devices, data centers, as well as public and private clouds.  Connectem’s vEPC solutions integrate seamlessly with Brocade’s software and physical networking product portfolios.

“This acquisition strengthens Brocade’s position in the networking industry as the adoption of software-centric networking continues to accelerate,” said Lloyd Carney, CEO of Brocade. “I am very pleased to bring this technology into our portfolio as we invest strategically in New IP across NFV and SDN to provide seemless data center and cloud solutions.”

“There is a step-function in scalability required to connect the billions of new devices joining the Internet of Things,” said Nishi Kant, CEO of Connectem.  “As an early strategic investor in our company, Brocade recognized that a new architectural approach would be required to meet these demands.  Connectem’s pioneering technology dramatically improves the flexibility, scalability, and total cost of ownership of mobile vEPC solutions. We are excited to realize the full extent of this vision as part of Brocade, a widely recognized leader and innovator in software networking.”

Citrix Intros 160 Gbps NetScaler Application Delivery Controller

Citrix introduced its next generation NetScaler MPX 25000 series, a carrier-grade application delivery controller (ADC) for communications service providers.  The new NetScaler is a two rack-unit (2RU) 160 gigabit-per-second appliance that enables operators to scale mobile S/Gi-LAN data plane capacity to 3.5 Tbps while preserving earlier capacity investments.

Significantly, the NetScaler MPX 25000 series can enable the transition to NFV by converting to a multi-tenant platform supporting dozens of virtual ADC instances. The company said it is able to capture cloud-scale efficiencies and economics in the NetScaler MPX 25000 series by using merchant silicon rather than the custom ASICs common to competing ADC products.

Key benefits of the NetScaler MPX 25000:

  • Scale mobile S/Gi-LAN services – Enables operators to scale any network use case, including optimization and gateway load balancing, CGNAT and traffic-steering in the data plane; and LTE DNS, SMPP, SIP, and Diameter load-balancing in the control plane.
  • Consolidate multiple use cases on a single platform – Allows operators to reduce use case-specific deployments that add complexity and inefficiency to the S/Gi-LAN environment. The most impactful consolidated scenario is that of carrier-grade network address translation (CGNAT) and data-plane load balancing and, optionally, traffic steering.
  • Minimize stranded investments – Helps operators protect their network infrastructure investment through Citrix TriScale scale-out clustering, which enables multiple appliances to be treated as a single logical and functional unit. As operators look to minimize up-front investment and scale capacity with new hardware, they can continue to make use of the original hardware.
  • Bridge the NFV gap – Helps operators protect and transition their network infrastructure to multi-tenant appliances supporting up to eighty virtual ADC instances with Citrix TriScale scale-in multi-tenancy.

“The NFV-driven discontinuity in the mobile industry is challenging operators to re-architect and rethink their delivery networks. Drawing on our experience from deployments in more than 140 mobile networks and in the world’s largest public clouds, Citrix continues to deliver the technology innovation to help mobile operators transform their networks. This is made possible by NetScaler - the industry’s only fully software-defined ADC," stated Klaus Oestermann, Senior Vice President and General Manager, Delivery Networks, Citrix.

Avaya Unveils SDN Fabric for Connecting "Anything" to Virtual Network

Avaya introduced its Open SDN Fx architecture for enabling automation and programmability from the core to the edge of enterprise networks.

Avaya said the aim of its SDN Fx architecture is “connect anything, anywhere” simplicity by allowing devices and users at the network edge to be added easily to the network.  The goal is to leverage an automated core that takes advantage of a single, network-wide Ethernet fabric to remove the need for manual configuration at each network hop; thus, reducing the potential for error and accelerating time to service.

Avaya’s SDN implementation is targeting environments such as those found in hospitals, manufacturing floors and casinos, which are blanketed with devices that require a more secure, mobile connection to the network, and may also require that the rest of the network is better protected from potential threats that could be triggered by them.

The Avaya SDN Fx architecture includes the following new products and features for Avaya Fabric Networking Technology:

  • Open Networking Adapter (ONA) - provides a plug-n-play network connection for any device with an Ethernet port including medical devices, manufacturing machines, and branch office switches. Targeted for non-IT personnel, this card deck-sized appliance automatically provisions a QoS-customized virtual path across the network that mitigates security risks, allowing simple, powerful management of thousands of devices.  
  • Fabric Orchestrator – an SDN controller embedded in a unified management instance. This appliance manages and orchestrates the Ethernet fabric as well as provides SDN Control to north and south bound interfaces. SDN capabilities include OpenFlow, OpenDaylight and OpenStack.
  • Fabric Extend – a new capability in Avaya Fabric Connect enables the extensibility of Fabric networking across any IP based network without loss of functionality. Investments in existing networking technologies are preserved while interconnecting strategic deployments of Fabric Connect across data centers, campuses and branches.

“CIOs are unnecessarily overburdened by archaic networks and frustrated by the disparity between the promised results of new technologies and the reality that most vendors deliver.  There’s a better way: Avaya Fabric Connect already relieves 75i percent of the top network issues identified by IT departments, and we’re building on that with SDN Fx. This is the foundation that accelerates deployment and improves performance of customer and team engagement solution and that the industry has been demanding. Avaya can deliver it today,” stated  Marc Randall, SVP and GM, Avaya Networking.

MagnaCom Demos its Multi-Carrier, OFDM Modulation

MagnaCom announced the release of its “WAM” technology for multi-carer OFDM to strategic partners. The company claims WAM enables an unprecedented 50% throughput gain and up to a 50% reduction in power, while remaining fully backwards compatible with QAM modulation.

The company said carriers can achieve substantially more data transmitted over the same spectrum, resulting in networks that deliver much higher speeds, have longer reach (coverage), and consume far less power. Orthogonal frequency-division multiplexing (OFDM) is a method of digital modulation in which a signal is split into several narrowband channels at different frequencies. OFDM is used in all modern cellular (LTE ) and WiFi (802.11n, 802.11ac).

“By extending our WAM technology into multi-carrier networks, MagnaCom continues to innovate with performance gains that were once thought impossible," said Yossi Cohen, co-founder and CEO of MagnaCom. “We have a vision of helping the mobile industry solve the 1000x mobile data by enabling carriers get much more out of their spectrum assets, dramatically lowering power consumption, and relentlessly challenging old assumptions. With the emergence of IoT and small wearable devices – the industry’s ability to miniaturize network devices, reduce power and increase distance will be paramount.”

Blueprint: vCPE Evolution and NFV-Powered Network Assurance

by Scott Sumner

With traditional business services shifting toward federated cloud connectivity, communication service providers (CSPs) have set a new course for delivering these critical services. Virtualizing customer premise equipment is a key part of their strategies—vCPE is a cost effective, proven technology approach that’s already showing significant returns.

The Promise of vCPE

Business services are not what they used to be. Enterprises increasingly are migrating to public and private clouds, and connectivity to these hosted resources is ever more critical for business success.

Margin and revenue threats to communications service providers (CSPs) lurk around every corner: public cloud platforms, over-the-top (OTT) wide area networking (WAN) technologies, and cheap, dumb pipes, to name just a few.

CSPs can win big, though, if they are able to cost-effectively deliver performance assured multi-cloud, multi-service connectivity. In this context, a vCPE strategy is becoming a critical component in a competitive service delivery model. For example, Colt Technology Services achieved remarkable benefits from its broad NFV/vCPE strategy intended to all but eliminate on-premises appliances; over a three-year period, virtualizing routers resulted in more than 70% CapEx savings.

Why NFV-Powered vCPE?

Data center connectivity services face intense cost pressure, yet cannot be delivered in a way that sacrifices quality of service (QoS) since this connectivity is the lifeline between enterprises and their business-critical infrastructure.

When a CSP adopts a vCPE strategy, their main goal is to use NFV to replace as much equipment as possible at the customer premises with virtualized equivalents, thereby reducing CapEx and increasing agility.

Many vCPE deployments already use intelligent NIDs to perform critical customer premises edge functions like Layer 2 and 3 QoS mapping, hierarchical traffic conditioning, service OAM, and performance monitoring, allowing routing and other L3+ functions to be located and/or virtualized deeper into the network.

But, while this approach is still a highly cost-effective method to deploy services in a multi-tenant environment, unit cost can lengthen return on investment (ROI) when serving a single customer

Curiously, CSPs often refer to the last remaining piece of equipment—a demarcation unit or intelligent edge appliance—as “the vCPE”. In this context, CSPs are taking virtualization to its logical conclusion, by applying NFV to the vCPE appliance itself .

By using NFV-based vCPE appliances, CSPs can not only realize significant CapEx and OpEx savings, but also increase their performance visibility, greatly decrease deployment time with customer self-install capabilities, outmaneuver competitors with higher cost structures, and compete on performance rather than price.

But, in the real world, what does it takes to replace racks of traditional CPE with centrally managed software?

A Closer Look: NFV-Powered vCPE Approaches

Adopting an NFV-powered vCPE strategy can only be successful if the technology involved seamlessly integrates legacy and virtualized approaches into a unified delivery platform. When that’s true, CSPs gain a smooth migration from existing infrastructure, within existing operational practices.

One approach to using vCPE technology is virtualizing all computationally intensive performance assurance functions—such as report generation, test session sequencing, and statistics—and retaining the minimum possible hardware to achieve the equivalent precision and line-rate processing offered by standalone edge appliances. Programmable smart SFPs or compact GbE modules can provide the local processing required—with the full feature set of NIDs realized when complemented by performance assurance virtual network functions (VNFs) hosted in a central controller.

Another approach (referred to here as vmCPE for “virtualized module CPE”) is to fully virtualize all vCPE functions to a software-based appliance running on COTS hardware. This vmCPE appliance can use the same catalog of centrally hosted VNFs, if its architecture permits.

As with all technology decisions, there are trade-offs between these two NFV-based vCPE approaches. The first approach (compact hardware modules) is more precise but not always practical; some locations—such as services terminating on a virtual machine—cannot be monitored using any physical device.

The vmCPE approach overcomes those visibility challenges and can also collect related VM metadata (CPU load, memory usage, etc.) to help isolate network issues arising from NFV infrastructure performance variation. But, vmCPE appliances cannot realize the same order of precision or packet-processing efficiency as hardware-based modules, because CPU load, varying degrees of access to underlying hardware, and the asynchronous, free-running clocks in virtual machines prevent deterministic time stamping and limit accuracy.

Regardless of approach, the ability to host and move VNFs to diverse locations needs to be supported by an effective NFV-powered vCPE solution deployment strategy. Various NFV-based implementation options emerge when standalone vCPE infrastructure is broken down into its logical components—allowing CSPs to employ variants that address site-specific requirements while retaining unified control and visibility over all service endpoints.

What’s Ahead for vCPE?

Clearly, the vCPE is becoming a vital component in the connectivity service delivery path and its lifecycle. This makes migration to NFV inevitable. The best, least painful way forward is to unify a variety of programmable vCPE options, giving CSPs the benefits of extensibility and cost savings via orchestrated virtualization implemented in an open, real-time architecture. Such an approach needs to be carefully designed to ensure solutions are highly extensible, scalable, and programmable, and openly interoperate with other platforms and functions.

vCPE implementations will increasingly require a mix of legacy, NFV-powered and fully-virtualized approaches, and will use software defined networking (SDN) standards to build a centrally controlled, highly-scalable distributed networking fabric that harmonizes physical and virtual instrumentation. Result: CSPs won’t have to manage standalone, NFV-based and fully virtualized vCPE infrastructure separately; these will seamlessly interact.
