| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | DOCSIS is the de facto standard for data transmissions on CATV/HFC networks. In the DOCSIS, an upstream channel is shared by many stations, and the stations sends out the data PDUs according to the random reservation manner. Recently, the DICSIS has introduced a concept in that the multiple channels can be combined together to get greater aggregate bandwidth. However, the DICSIS standard do not provide a contention resolution scheme for the aggregate upstream channel. On the other hand, for a single upstream channel, the DOCSIS employs the binary exponential back-off scheme as contention resolution mechanism. But, that provides too small/large request periods which is used in the random reservation, delay time increases rapidly as the offered traffic increases. In this paper, we propose a new contention resolution scheme for multi-channel CATV/HFC networks. Our scheme dynamically changes the size of request period according to traffic conditions. 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. |
