Internet2 Deploys ONOS to Provision Virtual Nets

Internet2 has deployed the Open source SDN Network Operating System (ONOS) on its nationwide research and education (R&E) network.

Five higher education institutions — Duke University, Florida International University, the Indiana GigaPoP, MAX and the University of Maryland – College Park, and the University of Utah — are connected to a virtual slice of the Internet2 nation-wide network that is piloting this next-generation advanced network technology.

Internet2 said it is using the capabilities of its SDN substrate to provision virtual networks based on FlowSpace Firewall. An ONOS cluster is deployed in a virtual network slice on the Internet2 network, controlling 38 OpenFlow-enabled Brocade and Juniper switches. The SDN-IP Peering application deployed atop ONOS peers with other, traditional networks. An SDN-based network like Internet2 provides benefits such as network programmability, lower TCO and removal of vendor lock-in. In this particular case, the centralized control plane leads to significant improvements in network operation efficiency for the Internet2 network.

“We worked closely together in a lab environment to prepare ONOS for production deployment on the Internet2 Network, providing many valuable insights on production deployment of SDN-controlled virtual networks in a multi-tenant environment,” said Luke Fowler, director of software and systems for the GlobalNOC.

“A primary feature of the Internet2 Network is its ability to serve as a ‘playground’ for piloting new advanced networking capabilities in a real-world environment with demanding users and advanced applications capabilities,” said Vietzke. “The ONOS and SDN-IP peering deployment is another demonstration of how Internet2 and the academic community continue to be a large scale platform in which pre-market innovations can be prototyped at scale.”

"ON.Lab, the ONOS Project and Internet2 have a very synergistic collaboration. At ON.Lab we develop interesting open source SDN platforms and Internet2 is a keen early adopter bringing new capabilities to its customers,” said Bill Snow, vice president of Engineering for ON.Lab. “With the deployment of ONOS on Internet2’s nationwide network, we get to validate and demonstrate ONOS’s scalability, performance and high availability in a production setting and learn from this experience to make ONOS better.”

Corsa Introduces SDN Metering and QoS for Big Data

Corsa Technology, a start-up based in Ottawa, unveiled new SDN metering and QoS (Quality of Service) capability for its line of performance SDN hardware. Bandwidth reservation is seen as especially interesting for organizations running Big Data workloads.

The traffic engineering function, which is based on OpenFlow 1.3, allows network architects to better manage bandwidth across their network with dynamic, policy-aware metering and QoS. Metering and queuing allows networks to create bandwidth profiles by putting limits and guarantees on traffic with particular classes.

Corsa said the advantage With SDN is that bandwidth limits are no longer fixed as part of a static topology and rigid hardware platform. Policy-aware provisioning can be dynamically pushed down to the flexible Corsa SDN hardware to make on-going adjustments to meters and queue assignments. The network can then make immediate, informed queuing and discard decisions under congestion. Real-time performance monitoring automatically returns meter statistics and is checked against policy such as SLAs. For network operators including service providers and ISPs, SDN metering and queuing allows new self-serve features to be offered such as “bandwidth reservation” where users can dynamically schedule and reserve bandwidth via separate class of service and meters.

“Dynamic, policy-driven networks is what SDN is about and SDN hardware solutions must be able to respond to these policy changes. SDN metering and QoS functionality is one important area for policy-driven networking requiring a very capable hardware solution,” said Yatish Kumar, Corsa Technology CTO. “Corsa’s line of performance SDN hardware has deep packet buffers, multi-table datapaths, and can support over a million active flows with flow modifications updated at >50,000 flow mods/sec. Together, these attributes make Corsa SDN metering and QoS a powerful tool for creating granular bandwidth profiles.”

Cavium Shows New Xpliant Silicon Driving SDN-enable Ethernet Switches

Cavium is demonstrating OpenFlow and OpenFlow-Hybrid Ethernet switches based on its new XPliant silicon.

Cavium's XPliant Ethernet switches deliver full line rate support in OpenFlow through XPliant's SDK APIs and integration of Open vSwitch (OVS) at an aggregate switching capacity of 3.2 terabits per second.

"Historically, large scale data center customers were only interested in the speeds and feeds of networking silicon. Now customers are looking for standards based vendor interoperable features that enable them to effectively control their networks, scale and grow over time," said Eric Hayes, VP/GM, Switch Platform Group at Cavium. "The XPA architecture is the ideal solution available today with all of these capabilities simultaneously in a cost effective manner."

Cavium noted its XPliant packet architecture XPA Software APIs expose the OVS control abstractions, enabling users to benefit from OVS rich management and networking features, such as L2 pipeline (VLANs, LAGs, FDB, STP etc.), bonding modes (LACP), and advanced tunneling protocols (Geneve, VxLAN, NVGRE) as well as future yet-to-be-defined standards. Now, through XPA Software and APIs, these open and industry proven features can be seamlessly invoked representing a truly hybrid switch optimized for virtualized environments, in a single hardware.

  • In September 2014, Cavium made its entrance into the merchant Ethernet switching silicon market with the launch of its programmable XPliant Packet Architecture and chips. The technology for this new product line originates with XPliant, a Silicon Valley start-up that Cavium agreed to acquire in July.  The new products target switches for cloud / enterprise data centers and service provider infrastructure, for both top-of-rack and backbone applications.
    The company said its design approach with its XPliant Packet Architecture was to take the dedicated function blocks present in conventional Layer 2 switching silicon and replace then will a flexible Table Type structure that enables software personalities to dictate the exact operation to be performed – for packet parsing, table look-ups, packet re-writes, fabric scheduling, and statistics and counters – without impacting performance. The company said its design fits well with the spine/leaf architecture of scale-out data centers.
