Edge Control Protocol

The Edge Control Protocol (ECP) provides reliable transport for the Port Extender Control and Status Protocol (PE-CSP) protocol. It includes a basic acknowledgement and retransmission facility. The Edge Control Protocol Data Unit (ECPDU) structure (ECPDU Structure) is slightly modified from the IEEE 802.1Q-2014. Preceding the ECPDU structure is the Destination and Source Address.
