v10 v11 1 1 [[PageOutline]] 2 2 = OpenFlow Specification = 3 * OpenFlow spec worked in collaboration with industry partners such as Google, Deutsche Telekom, France Telekom, HP, NEC, Marvell and Broadcom. 3 4 * We released ver1.1 of the specification with support for 4 5 * Multiple tables: An OpenFlow switch can now expose multiple tables to a controller. 5 6 * Multipath (Port groups): OpenFlow now supports the notion of "multipath" where a flow can be sent over one of several paths. 6 7 * Tags/tunnels: Tag support has been extended to include MPLS shim headers. VLAN tag handling has been modified to support packets with multiple VLAN tags (Q-in-Q encapsulation). Support has been added for tunnels via virtual ports. 8 * [http://www.openflow.org/documents/openflow-spec-v1.1.0.pdf Complete 1.1 Spec] 9 * Individual test cases and patches available in different development branches of OpenVSwitch and oftest 7 10 8 11 = Software = 9 The Clean Slate Lab atStanford University currently manages the following software packages for the OpenFlow aggregate:12 Stanford University currently manages the following software packages for the OpenFlow aggregate: 10 13 11 14 == OpenFlow reference implementation == … … 87 90 * Helping campuses deploy new software 88 91 * Upgraded Expedient and FlowVisor on all campuses 89 * Testing controllers on their behalfand sharing our experience92 * Testing controllers from BigSwitch and NEC on behalf of the campus and sharing our experience 90 93 * Interact with campuses to obtain feature requirements for SNAC 91 94 * The main request was to introduce VLAN partitioning in the controller … … 93 96 = Pronto Switch donation = 94 97 We started a solicitation for proposals to jumpstart OpenFlow production deployments through donation of Pronto switches. Based on several rounds of review, we donated close to 31 switches to the following institutions: 95 The GENI Project Office (GPO), in an effort to grow the OpenFlow networking substrate for GENI, funded Stanford Unviersity to distribute OpenFlow-enabled switches to campuses to help them create or grow their existing OpenFlow networks for both research and production use. We distributed approximately 30 Pronto 3290 switches among the following campuses:96 98 * MAX Gigapop (PIs: Abdella Battou, Balasubramania N.

The host traffic was routed through NLR and Internet2. 114 114 115 == Tutorial == 115 * In GEC10, we organized a tutorial for training campus operators to deploy OpenFlow. It was very successful and attended by nearly 45 persons.116 * In GEC10, we organized a tutorial for training campus operators and researchers to deploy OpenFlow.
