Stream Control Transmission Protocol (SCTP) is a transport layer protocol providing reliable transport of data like TCP but with message oriented features like UDP.

It provides some of the same service features of both: it is message-oriented like UDP and ensures reliable, in-sequence transport of messages with congestion control like TCP.

Why must endpoints manage conversions between bytes sent and received TSNs sent and received in SCTP congestion control?

As stated in RFC 3286: "...endpoints must manage the conversion between bytes sent and received and TSNs sent and received, since TSN is per chunk rather than per byte". How does this affect the congestion control algorithm?
