METHOD AND SYSTEM FOR TERMINATING SONET/SDH CIRCUITS IN AN IP NETWORK

摘要

A method and system for terminating SONET/SDH circuits in an IP network includes a SONET/SDH to Ethernet inter-working device/functionality implemented in a network element for mapping SONET/SDH channels into logical channels over an Ethernet connection. SONET/SDH channels are de-encapsulated to remove Layer-2 protocols and expose IP packets. The IP packets are encapsulated with Ethernet headers and logical tags for transmission over the Ethernet connection to their final destinations via a Provider Edge (IP) router.
