Abstract(in English) | In DOCSIS, an upstream channel is shared by many stations, and the stations send out their data PDUs according to the random reservation manner. Before data transmission, the station must send a request in a random access manner during the reservation period. Recently, DOCSIS has introduced a concept in that the multiple upstream channels can be combined together to get greater aggregated bandwidth. However, DOCSIS does not provide a suitable contention resolution scheme for the aggregated upstream channel. On the other hand, for single upstream channel, DOCSIS employs the Truncated Binary Exponential Back-off scheme for request period allocation. But, that provides too small/large request periods which are used in the random reservation, the delay increases rapidly as the offered traffic increases. In this paper, we propose a contention resolution scheme for multi-channel CATV networks. Our scheme estimates the offered traffic of upstream channel according to success/failure condition of bnadwidth reservation, and dynamically adjusts a parameter used to allocate the request period. In order to evaluate performance of the proposed scheme, we build a queueing model and execute computer simulation. Simulation results present that the proposed scheme provides the smaller delay than the conventional scheme. |
