Method and system for intermediate system level 2 transparency using the SONET LDCC

摘要

Methods and apparatus for assigning and/or storing routing metric values for routing traffic in a network having line terminating equipment connected by an line data communications channel (LDCC), so that routing traffic is sent across the LDCC. These methods and systems include a node and network that use the LDCC for transmitting routing information, such as Intermediate System to Intermediate System Level 2 routing traffic.
