1. A method for implementing channel scheduling algorithms in an optical router, the method comprising the steps of:

  • storing a set of channel unscheduled times from which a channel is free and corresponding channels SM at an associative process PM;

    storing a set of voids/gaps and a corresponding channels SG at an associative processor PG;

    determining availability of outbound data channels capable of carrying a data packet of duration B;

    selecting one channel from available data channels;

    assigning the data packet to the selected channel; and

    updating state information of the selected data channel, wherein the state information of a data channel includes channel unscheduled times for which the data channel has voids/gaps.
