2.2.3.1 Packet Header

To implement messages on top of existing, arbitrary transport layers, a packet header is included as part of the packet. The packet header precedes all data within the packet. It is always 8 bytes in length. Most importantly, the packet header states the Type (section 2.2.3.1.1) and Length (section 2.2.3.1.3) of the entire packet.

The following sections provide a detailed description of each item within the packet header.
