    22= OpenFlow Specification =
    3    * We released ver1.1 of the specification.
     3   * We released ver1.1 of the specification with support for
     4      * Multiple tables: An OpenFlow switch can now expose multiple tables to a controller.
     5      * Multipath (Port groups): OpenFlow now supports the notion of "multipath" where a flow can be sent over one of several paths.
     6      * 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.

    58= Software =
    69The Clean Slate Lab at Stanford University currently manages the following software packages for the OpenFlow aggregate:
    7    * OpenFlow reference implementation,
    8    * Indigo firmware for Pronto 3240 and 3290,
    9    * FlowVisor,
     10   * OpenFlow reference implementation
     11      * No changes
     12   * Indigo firmware for Pronto 3240 and 3290
     13      * Released Indigo-1.0 firmware with GUI configuration support
    1014   * Debugging/monitoring tools
     15      * Released Measurement box flash image and Scripts to run on server. This allows measuring and plotting (Time Series & CDF) the following metrics:
     16         * Flow Setup Time
     17         * Ping RTT & Loss
     18         * browsing delay
     19         * Switch CPU usage
     20         * Traffic Volume
     21         * # of Active Flows
     22         * Flow arrival rate
     23   * FlowVisor:
     24      * Feature enhancements
     25         * added msg statistics, see `fvctl get{Slice,Switch}Stats`
     26         * added flow tracking, see `fvctl get{Switch,SliceRewrite}FlowDB`
     27         * lots of performance improvements
     28         * flow setup time significantly improved
     29         * better error handling in create slice and change flowspace
     30      * Bug Fixes
     31         * fixed big I/O bug that caused switch flapping
     32         * password prompt no longer echos plaintext
     33         * changed drop rule policy from FS to packet
     34         * fixed NPE in FVSlicer
    1135   * Expedient and Opt-in Manager
     36      * Feature Upgrades
     37         * Allow users to specify hex or decimal numbers in the Flowspace entry page in the GUI
     38         * Ensure that created projects get owners
     39         * Add timer jobs to Expedient
     40         * Add expiration to slices
