Abstract
A method of reducing overhead for datagrams that are transmitted to or received from a serial link that reduces overhead to no more than four bytes. The datagram includes at least a Protocol Data Unit (PDU) field, a Start-of-PDU Header (SPH) field, and a SPH Control (SCH) field. The SPH and SCH fields consist of two bytes. The datagram may additionally include End-of-PDU Header (EPH) and EPH Control (ECH) fields. A method may also involve substitution of flags for subsequent headers that are identical to previous headers.
