GMPLS signaling for networks having multiple multiplexing levels

摘要

A method comprising the steps of receiving, with circuitry at a first node, a signal indicative of a request to set up an optical channel data unit label switched path between the first node and a second node in a network. Time slots for a plurality of types of signals to be transmitted from the first node to the second node are reserved, and a set up message is transmitted from the first node to the second node. The set up message identifies the plurality of signal types and the reserved time slots. The optical channel data unit label switched path is then provided between the first and second nodes.

1. A method comprising the steps of:
receiving, with circuitry at a first node, a signal indicative of a request to set up an optical channel data unit label switched path between the first node and a second node in a network; reserving time slots for a plurality of types of signals to be transmitted from the first node to the second node, the plurality of types of signals identify multiplexing levels within a multiplexing hierarchy of signals; transmitting a set up message from the first node to the second node, the set up message identifying the plurality of signal types and the reserved time slots, the set up message including data that identifies a number of the multiplexing levels; and providing the optical channel data unit label switched path between the first and second nodes, wherein the set up message includes a bit map that identifies the reserved time slots, the bit map having bits in which the bits indicate time slots based upon the bits relative positions within the bit map.
