ABSTRACT:
A method for transporting packet-switched control traffic in an optical network includes receiving a packet-switched datagram comprising a destination address. The method also includes identifying a destination Open Systems Interconnection (OSI) address of a destination network element in the optical network based on the destination address of the datagram. In addition, the method includes generating an OSI packet comprising the datagram and the destination OSI address, and transmitting the OSI packet on the optical network in an OSI channel of a Synchronous Optical Network (SONET) frame.
