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.
Claims33
A method for transporting packet-switched control traffic in an optical network, comprising:
- receiving a packet-switched datagram comprising a destination address;
- 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;
- 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.
A network element for transporting packet-switched control traffic in an optical network, comprising:
- an interface operable to receive a packet-switched datagram comprising a destination address;
- a tunneling module coupled to the interface, the tunneling module operable to identify a destination Open Systems Interconnection (OSI) address of a destination network element in the optical network based on the destination address of the datagram, the tunneling module also operable to generate an OSI packet comprising the datagram and the destination OSI address;
- and
- an optical interface coupled to the tunneling module and operable to transmit the OSI packet on the optical network in an OSI channel of a Synchronous Optical Network (SONET) frame.
A network element for transporting packet-switched control traffic in an optical network, comprising:
- an interface operable to receive a packet-switched datagram comprising a destination address;
- logic stored on at least one computer processable medium, the logic operable to:
- identify a destination Open Systems Interconnection (OSI) address of a destination network element in the optical network based on the destination address of the datagram;
- and
- generate an OSI packet comprising the datagram and the destination OSI address;
- and
- an optical interface operable to transmit the OSI packet on the optical network in an OSI channel of a Synchronous Optical Network (SONET) frame.
A propagated signal, comprising:
- a transmission medium;
- and
- a Synchronous Optical Network (SONET) frame carried on the transmission medium, the SONET frame comprising:
- a payload;
- an overhead comprising an Open Systems Interconnection (OSI) channel;
- and
- an OSI packet in the OSI channel, the OSI packet comprising a destination OSI address and a packet-switched datagram.
