Wave and Equation Based Rate Control (WEBRC) Building Block

UDP Usage Guidelines

“…The IETF has defined a reliable multicast framework [RFC3048] and several building blocks to aid the designers of multicast applications, such as [RFC3738] or [RFC4654].…”

“…o Receiver-driven congestion control, which does not require a receiver to send explicit UDP control messages for congestion control (e.g., [RFC3738], [RFC5775]). Instead, the sender distributes the data across multiple IP multicast groups (e.g., using a set of {S,G} channels).…”

Services Provided by IETF Transport Protocols and Congestion Control Mechanisms

“…These methods utilize a throughput equation to determine the maximum acceptable rate. Such methods are used with DCCP CCID 3 [RFC4342], CCID 4 [RFC5622], WEBRC [RFC3738], and other applications.…”

Unicast UDP Usage Guidelines for Application Designers

“…Multicast and broadcast senders may transmit to multiple receivers across potentially very heterogeneous paths at the same time, which significantly complicates congestion control, flow control, and reliability mechanisms. The IETF has defined a reliable multicast framework [RFC3048] and several building blocks to aid the designers of multicast applications, such as [RFC3738] or [RFC4654]. Anycast senders must be aware that successive messages sent to the same anycast IP address may be delivered to different anycast nodes, i.e., arrive at different locations in the topology.…”
