Charter for Working Group

The QUIC WG originated the specifications describing version 1 of QUIC, a UDP-based, stream-multiplexing, encrypted transport protocol.

The WG acts as the focal point for any QUIC-related work in the IETF. It is chartered to pursue work in the areas detailed below:

  1. The first area of work is maintenance and evolution of the existing QUIC specifications:

     * Maintenance and evolution of the QUIC base specifications that describe its invariants, core transport mechanisms, security and privacy properties, loss detection and recovery, congestion control, version and extension negotiation, etc. This includes the specification of new versions of QUIC.
     * Maintenance and evolution of the existing QUIC extensions specified by the WG.

    WG adoption of work items falling into this first area of work needs to be strongly motivated by existing or ongoing production deployments of QUIC at scale, and needs to carefully consider its impact on the applications and higher-layer protocols (simply called "application protocols" in the rest of this charter) that have adopted QUIC as a transport.

  2. The second area of work is supporting the deployability of QUIC, which includes specifications and documents such as applicability and manageability statements, improved operation with load balancers, the specification of a logging format, and more.

  3. The third area of work is the specification of new extensions to QUIC. The WG will primarily focus on extensions to the QUIC transport layer, i.e., extensions to QUIC that have broad applicability to multiple application protocols. The WG may also publish specifications to publicly document deployed proprietary extensions or to enable wider experimentation with proposed new protocol features.

Specifications describing how new or existing application protocols use the QUIC transport layer, called application protocol mappings below, need not be specified in the QUIC WG, although they can. The QUIC WG will collaborate with other groups that define such application protocols that intend to use QUIC. New application protocol mappings might require QUIC extensions and it may be efficient to define these alongside the mapping specifications. Groups that define application protocols using QUIC, or extensions to QUIC in support of those protocols, are strongly requested to consult with the QUIC WG and seek early and ongoing review of and collaboration on proposals. This is intended to reduce the possibility of duplicate work and/or conflicts with other extensions.

The QUIC WG originated HTTP/3, the mapping of HTTP to QUIC, and the QPACK header compression scheme. These specifications are now maintained in the HTTP WG.

Defining new congestion control schemes is explicitly out of scope for the WG. However, new QUIC extensions that support development and experimentation with new congestion control schemes may fall under the third work area.
