Charter charter-ietf-hybi-02

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
       point).
  
    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
    subprotocols.
  
    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.
