Abstract
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. The 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.
Claims17
A method for terminating SONET/SDH circuits in an IP network to deliver IP packets, comprising:
- providing a Gateway having a network element for receiving the SONET/SDH circuits and an IP router for routing the IP packets to their final destinations;
- providing an Ethernet interface between the network element and the IP router;
- and
- translating and bridging the IP packets received at the network element from the SONET/SDH access circuits onto the Ethernet interface.
A system for terminating SONET/SDH circuits in an IP network to deliver IP packets, comprising:
- a Gateway having a network element for receiving the SONET/SDH circuits and an IP router for routing the IP packets to their final destinations;
- an Ethernet interface in communication with the network element and the IP router;
- wherein the network element is operative to receive, translate and bridge the SONET/SDH access circuits onto the Ethernet interface.
For use in an IP network, a SONET/SDH to Ethernet inter-working device, comprising:
- means for receiving SONET/SDH channels;
- means for de-encapsulating the SONET/SDH channels to remove any Layer-2 protocol and expose IP packets;
- and
- means for mapping the SONET/SDH channels into logical channels over an Ethernet connection for receipt by an router.
