Abstract
The present invention relates to a slot reuse method and arrangement for increasement of the throughput in a DTM (Dynamic Synchronous Transfer Mode) network. The slot reuse according to the invention comprises extending the DTM block token format to include parameters describing the segment(s) between source and destination node, reserving block token capacity only on the segment(s) between source and destination node, and enabling simultaneous transmissions in the same slot over disjointed segments of the network. The slot reuse can also comprise merging two or more segment-consecutive tokens, representing the same slot range, into a single token when existing in the free pool of a node.
Claims13
A slot reuse method for increasing a throughput in a dynamic synchronous transfer mode (DTM) network, the method comprising the steps of:
- providing a DTM block token format having a capacity;
- providing a source and a destination node;
- providing parameters and segments;
- providing disjointed segments of the DTM network;
- providing a plurality of slots;
- extending the DTM block token format to include the parameters describing the segments disposed between the source and the destination node;
- reserving the capacity of the DTM block token format only on the segments disposed between the source and the destination node;
- and
- transmitting the throughput simultaneously in the same slot over disjointed segments of the DTM network.
A slot reuse arrangement for increasing a throughput in a dynamic synchronous transfer mode (DTM) network comprising:
- a plurality of slots having disjointed segments;
- an extended DTM block token format including parameters describing segments disposed between a source and a destination node;
- and
- nodes arranged to reserve block token capacity only on segments disposed between the source and the destination node to permit a simultaneous transmission in the same slot over the disjointed segments of the DTM network.
