Abstract
Provided are a system and method for transferring management channel information (inband or using path overhead) over a synchronous optical network (SONET). In one example using inband management information, the method includes encapsulating management information in an internet protocol (IP) packet and encapsulating the IP packet in an Ethernet frame. The Ethernet frame is tagged with a management tag to differentiate the frame from the data traffic sent via the network.
