Vyatta Debuts Vplane Forwarding Plane Software

Vyatta introduced a highly scalable forwarding plane software solution for next-generation enterprise and cloud network designs.


Vyatta vPlane's fast-path architecture promises far better performance than the company's previous generation software on the same off-the-shelf hardware. Leveraging the new fast-path architecture on an Intel Westmere-class system, Vyatta vPlane is capable of delivering more than 8 million packets per second per core, more than a 10x improvement over Vyatta without vPlane. Additionally, since vPlane scales linearly with the addition of cores, an entire Westmere system can deliver 35 million packets per second in only a single rack-unit of datacenter space.

A key advantage is the physical decoupling of the software forwarding plane from the control plane.

Vyatta said its implementation is able to accommodate new and emerging standards such as OpenFlow.

NEC: "SDN is Ready to Go!"

NEC has made an early bet on OpenFlow and software defined networking (SDN), said Kaoru Yano, Chairman of the Board of NEC Corporation, in a keynote address at the Open Networking Summit in Santa Clara, California. The company has been involved in SDN since its early days at Stanford and has played a leading role in many OpenFlow projects in Japan and around the world. This pioneering effort is really an extension of the company's long term research in computers and communications.


Some key points from his presentation:
  • The value proposition of SDN can be summed up as follows: simple, fast, scalable, and open.

  • SDN's key function is to automatically manage network traffic and distribute it as needed.

  • SDN enables network traffic t0 be scaled and managed because network control is separated from network hardware.

  • SDN allows users to upgrade the network independently of the hardware.

  • NEC's OpenFlow formula is: Simplification + Virtualization + Visualization.

  • NEC's unique SDN proposition is a logical abstraction called the Virtual Tenant Network -- this enables the complete separation of the logical plane from the physical plane. Users can design the Layer 2/3 network as they wish and then this design will be automatically mapped to the physical hardware.

  • NEC's ProgrammableFlow enables drag-and-drop configuration of virtual tenants in a data center.

  • NEC currently has 100+ SDN system trials underway.

  • Current SDN applications will include academic networks, data centers, enterprise networks and the backbone infrastructure of telecom carriers.

  • Geneis Hosting Solutions is using SDN to provide flexible global IP address assignment. The deployment has achieved a 60% reduction in global IP address and saved 100 hours per week of service support. The network has achieved 99.999% availability.

  • Nippon Express using NEC's ProgrammableFlow to achieve virtualization flexibility and reduce service delivery time. The deployment reduced tithe rack space required for core switches by 70% and reduced power consumption by 80%.

  • NEC is using Programmable Flow for its own multi-purpose data center. Following last year's earthquake and tsunami, NEC needed to relocate data center facilities to western Japan due to power restrictions. ProgrammableFlow simplified this transfer process.

  • Software-defined networking can provide much smarter congestion control and recovery following a major disaster as experienced last year.

The Open Networking Summit is planning to post a video of their conference following the event.

Google Links Data Centers with Software-defined Networking

WAN economics to date have not made Google happy, said Urs Hoelzle, SVP of Technical Infrastructure and Google Fellow, speaking at the Open Networking Summit 2012 in Santa Clara, California. Ideally, the cost per bit should go down as the network scales, but this is not really true in a really massive backbone like Google's. This scale requires more expensive hardware and manual management of very complex software. The goal should be to manage the WAN as a fabric and not as a collection of individual boxes. Current equipment and protocols do not allow this. Google's ambition is to build a WAN that is higher performance, more fault tolerant and cheaper.


Some notes from his presentation:
  • Google currently operates two WAN backbones. I-Scale is the Internet facing backbone that carries user traffic. It must have bulletproof performance. G-Scale is the internal backbone that carries traffic between Google's data centers worldwide. The G-Scale network has been used to experiment with SDN.

  • Google chose to pursue SDN in order to separate hardware from software. This enables it to choose hardware based on necessary features and to choose software based on protocol requirements.

  • SDN provides logically, centralized network control. The goal is to be more deterministic, more efficient and more fault-tolerant.

  • SDN enables better centralized traffic engineering, such as an ability for the network to converge quickly to target optimum on a link failure.

  • Deterministic behavior should simplify planning vs over provisioning for worst case variability.

  • The SDN controller uses modern server hardware, giving it more flexibility than conventional routers.

  • Switches are virtualized with real OpenFlow and the company can attach real monitoring and alerting servers. Testing is vastly simplified.

  • The move to SDN is really about picking the right tool for the right job.

  • Google's OpenFlow WAN activity really started moving in 2010. Less than two years later, Google is now running the G-Scale network on OpenFlow-controlled switches. 100% of its production data center to data center traffic is now on this new SDN-powered network.

  • Google built their own OpenFlow switch because none were commercially available. The switch was built from merchant silicon. It has scaled to hundred of nonblocking 10GE ports.

  • Google's practice is to simplify every software stack and hardware element as much as possible, removing anything that is not absolutely necessary.

  • Multiple switch chassis are used in each domain.

  • Google is using open source routing stacks for BGP and ISIS.

  • The OpenFlow-controlled switches look like regular routers. BGP/ISIS/OSPF now interfaces with OpenFlow controller to program the switch state.

  • All data center backbone traffic is now carried by the new network. The old network is turned off.

  • Google started rolling out centralized traffic engineering in January.

  • Google is already seeing higher network utilization and gaining the benefit of flexible management of end-to-end paths for maintenance.

  • Over the past six months, the new network has seen a high degree of stability with minimal outages.

  • The new SDN-powered network is meeting the company's SLAs.

  • It is still too early to quantify the economics.

  • A key benefit is the unified view of the network fabric -- higher QoS awareness and predictability.

  • The OpenFlow protocol is really barebones at this point, but it is good enough for real world networks at Google scale.

  • 100% of traffic carried on the new network.

NEC's OpenFlow Enables Multitenant Network Virtualization

NEC released its next generation OpenFlow solution, featuring the ability to design, deploy, monitor and manage secure, multitenant networks from a single point of control.


NEC's ProgrammableFlow 2.0 Product Suite builds upon the OpenFlow 1.0 standard to provide more control of network resources, while maintaining interoperability with other OpenFlow compliant equipment. The company said its multitenant network virtualization technology provides the ability to programmatically manage the way traffic flows across the network, optimizing use of existing network resources and the appliances, servers, and storage connecting to the network.

ProgrammableFlow 2.0 Updates Include:

Policy Based Multipath Routing – The physical path traffic takes across the network can be distributed across equal cost links and by path policy. The path policy can be customized dynamically based on traffic type, providing policy based traffic steering.

Point and Click Network Deployment - Virtual networks can be created and deployed from a single user interface. Leveraging NEC’s Virtual Tenant Network (VTN) technology, the Version 2.0 of the ProgrammableFlow Controller interface allows operators to create/delete virtual networks, manage virtual network topology setting, and configuration.

Network Service/Appliance Failover – ProgrammableFlow continuously monitors the status of network services and can automatically redirect traffic to services in the case the primary service is no longer reachable.

Bandwidth Monitor – With the bandwidth monitor function, statistical information can be periodically obtained from OpenFlow switches. The number of bytes received from the physical port of the switches can be collected.

"This release of the ProgrammableFlow 2.0 extends NEC’s lead in software defined networking," said Don Clark, Director of Business Development, IT Platform Technologies, NEC Corporation of America. "Deployed as data center fabric or as a virtualization layer for network services, ProgrammableFlow version 2.0’s automation and ease of use allows customers to quickly deploy and gain the benefits of a software defined network."
