Real-Time Communication in WEB-browsers (rtcweb) ------------------------------------------------ Charter Current Status: Active Chairs: Sean Turner <sean+ietf@sn3rd.com> Ted Hardie <ted.ietf@gmail.com> Applications and Real-Time Area Directors: Ben Campbell <ben@nostrum.com> Alexey Melnikov <aamelnikov@fastmail.fm> Adam Roach <adam@nostrum.com> Applications and Real-Time Area Advisor: Adam Roach <adam@nostrum.com> Mailing Lists: General Discussion: rtcweb@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/rtcweb Archive: https://mailarchive.ietf.org/arch/browse/rtcweb/ Description of Working Group: There are a number of proprietary implementations that provide direct interactive rich communication using audio, video, collaboration, games, etc. between two peers' web-browsers. These are not interoperable, as they require non-standard extensions or plugins to work. There is a desire to standardize the basis for such communication so that interoperable communication can be established between any compatible browsers. The goal is to enable innovation on top of a set of basic components. One core component is to enable real-time media like audio and video, a second is to enable data transfer directly between clients. This work will be done in collaboration with the W3C. The IETF WG will produce architecture and requirements for selection and profiling of the on the wire protocols. The architecture needs to be coordinated with W3C. The IETF WG work will identify state information and events that need to be exposed in the APIs as input to W3C. The W3C will be responsible for defining APIs to ensure that application developers can control the components. We will reach out to the developer community for consultation and early feedback on implementation. The security and privacy goals and requirements will be developed by the WG. The security model needs to be coordinated with the W3C. The work will also consider where support for extensibility is needed. RTP functionalities, media formats, security algorithms are example of things that commonly need extensions, additions or replacement, and thus some support for negotiation between clients is required. The WG will perform the following work: 1. Define the communication model in detail, including how session management is to occur within the model. 2. Define a security model that describes the security and privacy goals and specifies the security protocol mechanisms necessary to achieve those goals. 3. Define the solution - protocols and API requirements - for firewall and NAT traversal. 4. Define which media functions and extensions shall be supported in the client and their usage for real-time media, including media adaptation to ensure congestion safe usage. 5. Define what functionalities in the solution, such as media codecs, security algorithms, etc., can be extended and how the extensibility mechanisms works. 6. Define a set of media formats that must or should be supported by a client to improve interoperability. 7. Define how non media data is transported between clients in a secure and congestion safe way. 8. Provide W3C input for the APIs that comes from the communication model and the selected components and protocols that are part of the solution. 9. The group will consider options for interworking with legacy VoIP equipment. This work will be done primarily by using already defined protocols or functionalities. If there is identification of missing protocols or functionalities, such work can be requested to be done in another working group with a suitable charter or by requests for chartering it in this WG or another WG. The following topics will be out of scope for the initial phase of the WG: RTSP, RSVP, NSIS, Location services, Resource Priority, and IM & Presence specific features. The products of the working group will support security and keying as required by BCP 61 and be defined for IPv4, IPv6, and dual stack deployments. The Working Group will consider the possibility of defining a browser component that implements an existing session negotiation and management protocol. The working group will follow BCP 79, and adhere to the spirit of BCP 79. The working group cannot explicitly rule out the possibility of adopting encumbered technologies; however, the working group will try to avoid encumbered technologies that require royalties or other encumbrances that would prevent such technologies from being easy to use in web browsers.
