The WebRTC data channel mechanism does not support SCTP multihoming.

Support of reliable or partially reliable message transport.

Support of arbitrarily large user messages by providing fragmentation.

Support of ordered and out-of-order message delivery.

Support of multiple unidirectional streams, each providing its own.

modifiable congestion control for integration with the.

Usage of TCP-friendly congestion control.

The important features of SCTP in the WebRTC context are the following: ¶ 10: It must be possible to implement the protocol stack in the user application space. Must support Path MTU (PMTU) discovery and must not rely on ICMP or ICMPv6īeing generated or being passed back, especially for PMTU discovery. 9: The data channel transport protocol should avoid IP fragmentation. Image-file-transfer implementations might enforce a reasonable message size (i.e., a virtual socket stream) at the application layer for such things as 8: The data channel transport protocol should support unbounded-length "messages" Inside its protocol fields doing so reveals potentially private informationĪnd leads to failure if the address is depended upon. 7: The data channel transport protocol must not encode local IP addresses It also must ensure that largeĭata channel transfers don't unduly delay traffic on other dataĬhannels. JavaScript application passes to be sent. IP-layer fragmentation can be avoided no matter how large a message the 6: Data channels must provide message fragmentation support such that 5: Data channels must be secured, which allows for confidentiality, This will interact with the congestion control algorithms. Relative priority of each data channel relative to each other 4: The application should be able to provide guidance as to the Not cause excessive problems when run in parallel with TCP connections. Problems for these SRTP media streams, and that the WebRTC PeerConnection does This ensures that data channels don't cause congestion

3: Data channels of a PeerConnection must be congestion controlledĮither individually, as a class, or in conjunction with the SRTP media streams 2: Both reliable and unreliable data channels must be supported. Of these SRTP media streams may change at any time. Note that there may be zero or more SRTP media streams in parallel with the dataĬhannels in the same PeerConnection, and the number and state (active/inactive) 1: Multiple simultaneous data channels must be supported. Please note that this section is informational only. This section lists the requirements for Peer-to-Peer (P2P) data channels between When, they appear in all capitals, as shown here. Used by the WebRTC protocol framework for transporting non-media dataĪre to be interpreted as described in BCP 14 Section 5 discusses SCTP over DTLS over UDP and The remainder of this document is organized as follows:Īnd requirements for both unreliable and reliable peer-to-peer data channels Using allows the interleave of large messages toĪvoid monopolization and adds support for Using the reconfiguration extension defined in Īllows an increase in the number of streams during the lifetime of an SCTPĪssociation and allows individual SCTP streams to be reset. Partially reliable, delivery modes for user messages.

Provides multiple streams natively with reliable, and the relevant SCTP, as specified in with the partial reliabilityĮxtension (PR-SCTP) defined in and the additional policies This data transport service operates in parallel to the SRTP media transports,Īnd all of them can eventually share a single UDP port number. Solution together with confidentiality, source authentication, and Latest version, DTLS 1.2, is defined in andĪn upcoming version, DTLS 1.3, is defined in. Non-media data is handled by using the Stream Control Transmission Protocol (SCTP) encapsulated Media is sent using the Secure Real-time Transport Protocol (SRTP) (for example, audio and video) and non-media data. In the WebRTC framework, communication between the parties consists of media Transferring User Data on a Data Channel ¶ SCTP over DTLS over UDP Considerations ¶Ħ.6.
