Abstract: A network manager begins to integrate optical crossconnect functionality in an optical packet switching apparatus by transmitting a request to a resource management mechanism for allocation for an output port with respect to an input port in an optical switching matrix. The resource management mechanism then queries a port availability database to determine the availability of the requested output port. If an output port is available, the resource management mechanism then reserves the requested output port. The resource management mechanism then transmits mapping information for an optical path between the input port and the reserved output port to an optical switch control mechanism. The optical switch control mechanism then creates the optical path between the said input port the reserved output port. Finally, the optical switch control mechanism informs the resource management mechanism that the optical path is established.
