The … Webb7 juli 2009 · A full ethernet frame would have an IP packet of length 1500 byte, so typically an SCTP packet of size 1480, which means 1468 for chunks. However, the limitation of max. use message sizes is different from limiting the a_rwnd. The statement in the RFC is that the a_rwnd must be 1500 or larger on the INIT and INIT-ACK.

An SCTP packet consists of two basic sections: 1. The common header, which occupies the first 12 bytes and is highlighted in blue. 2. The data chunks, which occupy the remaining portion of the packet. The first chunk is highlighted in green, and the last of N chunks (Chunk N) is highlighted in red.
