Abstract

Methods and systems of a leased line appliance (LLA) network switching system that includes using LLAs for leased line circuits (LLCs) to Internet Protocol (IP) transceiving, IP to LLCs transceiving, and an IP switch fabric having multiple parallel paths as a switching/routing network are disclosed. Each of the LLAs at the edge of the IP switch fabric may perform LLC to IP packet assembly procedures, may perform IP packet to LLC re-assembly procedures, and may utilize the protocol fields of the IP packet header of the IP packet for IP packet transport, which may enable the transport of very high speed leased line services to be carried over an IP/MPLS network using the IP switch fabric.
