Description of Working Group:

      The BiDirectional or Server-Initiated HTTP (HyBi) working group
      defines the WebSocket Protocol, a technology for bidirectional
      communication between an HTTP client and an HTTP server that
      provides greater efficiency than previous approaches (e.g., use
      of hanging requests or long polling).

      Having completed work on the core protocol (RFC 6455), the group
      continues to define extensions for use by WebSocket
      implementations.  The following extensions and optimizations are
      currently in scope:

      1. A per-frame compression extension to improve bandwidth
         usage (draft-tyoshino-hybi-websocket-perframe-deflate is a
         likely starting point).

      2. A multiplexing extension to improve the scalability of the
         WebSocket protocol (draft-tamplin-hybi-google-mux is a likely
         starting point).

      3. Timeout-handling capabilities to reduce the chattiness of the
         protocol (draft-thomson-hybi-http-timeout is a likely starting

      The working group will also serve as a discussion venue for
      subprotocols.  However, no subprotocol is currently chartered as a
      deliverable, and the WG must be rechartered to work on any

      The group will not work on an updated version of the WebSocket
      protocol, unless it is specifically rechartered to do so.

      The group will continue coordinating with the W3C WepApps working
      group with respect to the above deliverables and to ensure the best
      match possible between the WebSocket protocol and the WebSocket API.
      The group will also continue coordinating with other working groups
      within the IETF (e.g., HTTPBIS) as appropriate.

Goals and Milestones:
  Done     - Adopt a WG item for the per-frame compression extension
  Done     - Issue WG last call on the per-frame compression extension
  Done     - Send compression extension to IESG for consideration as a Proposed Standard
