Patent ID: 7782906

Claim:
A method for carrying Frame Relay over Ethernet, comprising the steps of: encapsulating a Frame Relay frame with frame header and tail flag sequences having been removed into an Ethernet frame, and transmitting the Ethernet frame over Ethernet; and receiving the Ethernet frame, removing a header from the Ethernet frame, reconstructing the Frame Relay frame, adding flag sequences to the Frame Relay frame, and transmitting the Frame Relay frame to a destination Frame Relay network; wherein the step of encapsulating the Frame Relay frame with frame header and tail flag sequences having been removed into an Ethernet frame comprises: determining a control word and performing payload encapsulation; mapping a Data Link Connection Identifier (DLCI) to a Virtual network Connection Identifier (VCE ID), and encapsulating the VCE ID; and encapsulating a header for the Ethernet frame, generating an Ethernet Frame Check Sequence (FCS) and adding the FCS into the Ethernet frame.
