Abstract

The peculiarities of transmitting IP-based services over DOCSIS-based CATV/HFC networks are presented. The way DOCSIS protocol acts in data transmission and in collisions solving is discussed in details. The TCP effectiveness is evaluated for CATV / HFC networks that are asymmetrical in terms of channel capacity in the upstream and the downstream direction. Architectures for the upstream and the downstream segmentation are suggested that implement switches to improve the quality of the subscriber services provided. The minimum bit rate is determined that makes it possible for the VoIP service with silence suppression (UGS-AD according to the DOCSIS standard) to be provided to the cable television network subscribers. Ill. 5, bibl. 7 (in English; summaries in English, Russian and Lithuanian).
