METHOD TO IMPROVE MULTICAST SERVICE PERFORMANCE OF FTTDP SUBSCRIBER NETWORK TO WHICH G.HN TECHNOLOGY IS APPLIED

摘要

The present invention relates to a method to improve multicast service performance of an FTTdp subscriber network to which a G.hn technology is applied to extend a multicast service providing distance and to improve performance by retransmitting a damaged packet in the occurrence of damage to a multicast packet generated by the performance limitation of a copper line bundle according to an in-house wiring environment when a high speed communication over gigabit is provided by applying the G.hn technology for the home network to a telephone subscriber network. The method can generate an error corresponding to a corresponding identification number and to intentionally restore by generating a value in which an identification number changed along the appointed pattern is added when an error confirmation code (for example, CRC) is generated for a packet transmitted from a port of line collecting equipment; uses an identifier to classify an identification number corresponding to intentional errors when the intentional errors in the received terminal (CPE) maintains an appointed pattern along with the order of a transmission packet; and can specify the packet of a multicast method without changing a communication frame required to reduce compatibility with a configuration to generate and analyze a non-standard communication frame. The method has an effect to improve a reception performance by the retransmission of a packet including errors and to extend a reception distance.;COPYRIGHT KIPO 2016
