Abstract
A method for carrying Frame Relay over Ethernet comprises: receiving a Frame Relay frame, and removing header and tail flag sequences from the Frame Relay frame; determining a control word and performing payload encapsulation; mapping a DLCI to a VCE ID and encapsulating the VCE ID; encapsulating an Ethernet frame header, generating an Ethernet FCS and transmitting the Ethernet frame to Ethernet; and, receiving the Ethernet frame, checking the Ethernet frame and removing the Ethernet frame header; removing the VCE ID, and mapping the VCE ID to the DLCI; obtaining the control word, obtaining Frame Relay information from the payload and reconstructing the Frame Relay frame according to the control word; adding flag sequences to the Frame Relay frame, and transmitting the Frame Relay frame to a Frame Relay network. According to the invention, Frame Relay carried over Ethernet may be implemented without relying on the types of the upper layer protocols.
