HIGH SPEED ETHERNET BASED ON SONET TECHNOLOGY

摘要

A high-speed Ethemet using Thin SONET technology as the physical layer carrier makes use the large embedded base of SONET equipment, and is a step forward in integrating WANs, MANs and LANs. The HS Ethemet also takes advantage of current SONET functionality, such as framing, scrambling, integrity, etc. FEC fields are provided in the TOH for achieving a high level of error correction. The HS Ethemet frame comprises a length-type field generated at the PCS sublayer and a HEC field generated at the PMA layer. The frames are routed within a network using the source address, the destination address and a label.
