Latest Release of OpenFlow Adds IPv6, Tunneling, QoS
The Open Networking Foundation (ONF) approved OpenFlow 1.3.0, adding a number of updates to the standard for real-world deployment in wide-ranging environments.
OpenFlow 1.3.0 was developed by the Extensibility Working Group of ONF, which is tasked with moving technical work forward and making OpenFlow more flexible to enable a rich set of features and broad set of implementations. The new version of the OpenFlow protocol includes support for:
- IPv6 deployment that enables OpenFlow controllers to implement IPv6 RFCs and routing
- Tunneling and logical port abstraction used in datacenters, virtualized private networks (VPN), and more
- Provider Backbone Bridging (PBB), which is a lightweight tunneling standard used between datacenters
- Quality of Service (QoS) through a new per-flow metering feature to precisely control the usage of the network bandwidth
- Features that enable the controller to better select the information it gets from the switch with per-flow metering and per-connection event filtering.
OF-Config 1.1 was also approved, which is an update for the configuration and management protocol for OpenFlow switches. The updated configuration protocol is an important aspect of the evolution of OpenFlow and includes capability discovery, tunnel configuration, error handling, and new security features. OF-Config 1.1 allows OpenFlow controllers and OpenFlow switches from different vendors to be easily deployed and managed in the same datacenter or network.
"ONF continues to focus its technical work on the topics that are most important to the networking market,” said Dan Pitt, executive director, ONF. “OpenFlow brings market-defining value into the SDN eco-system. The approval of OpenFlow 1.3.0 and OF-Config 1.1 demonstrates the Foundation’s commitment to reducing time-to-value in real-world deployments where operational efficiency and managing complexity are primary concerns. We are eager for member companies to move forward with the implementation and deployment of these updates because doing so will allow processes to be defined ‘on the fly’ and deployed automatically, thus driving the commercialization of OpenFlow-based SDN for the benefit of customers."

IEEE Enhances 802.22 White spaces Spec
 The IEEE P802.22b Amendment Project for Enhanced Broadband Services and Monitoring Applications has officially been approved. The new amendment enhances the IEEE 802.22-2011 standard to accommodate a wide variety of applications using cognitive radio technology in Television White Spaces (TVWS). These applications include long range and regional area smart grid, critical infrastructure monitoring, triple play services like providing voice, video and data, backhaul for broadband access, offloading cellular telephony traffic, regional area public safety and homeland security networks, emergency broadband services, monitoring rain forests, monitoring livestock, and border protection etc.
Additional information on this amendment PAR can be found on the IEEE 802.22 WG webpage....

OIF Demo: Multi-Vendor, Multi-Carrier Ethernet over OTN
 At last week's OFC/NFOEC conference in Los Angeles, the Optical Internetworking Forum showcased a multi-vendor, multi-carrier implementation of High-Speed Dynamic Services.
In a test conducted simultaneously in Europe, Asia and North America, the OIF showed multi-vendor data plane and control plane interworking of systems supporting Ethernet Services over OTN in a multi-carrier environment. On-demand services were provisioned, based on ASON/GMPLS control plane functions. The demonstration leveraged draft GMPLS extensions for the OTN hierarchy. It also tested multi-layer and OTN extensions to E-NNI 2.0.
Deutsche Telekom, France Telecom/Orange, KDDI and Verizon served as telecom carrier hosts for the demonstration.
Vendor Participants included ADVA Optical Networking, Alcatel-Lucent, Ciena, EXFO, Huawei, Marben Products, Metaswitch and Tellabs. Consulting Carriers included AT&T, China Telecom and NTT.

OIF Demos 25-28 Gbaud Interoperability
 At last week's OFC/NFOEC conference in Los Angeles, the OIF hosted a physical layer interoperability event focused on Enabling High-Speed Dynamic Services.
Specifically, the OIF’s Physical and Link Layer demonstration showcased the forum’s CEI 28G Very Short Reach (VSR) draft implementation agreement that defines chip-to-module electrical interfaces and the OIF's CEI 25G Long Reach (LR) implementation agreement that defines backplane electrical interfaces.
There were five individual demos made up of ten participating companies and one test equipment vendor.
Three demos focused on Very Short Reach chip-to-module applications based upon CEI-28G-VSR.
Two demos focused on Long Reach backplane applications using CEI-25G-LR.
Participants included Altera, Amphenol, Fujitsu Optical Components, Gennum, IBM, Inphi, Luxtera, Molex, TE Connectivity and Xilinx. Test equipment was supplied by Tektronix....
