OPTICAL GIGABIT ETHERNET SWITCH WHICH PROVIDES INTERNET GROUP MANAGEMENT PROTOCOL FUNCTION FOR HFC NETWORK IPTV SERVICE

摘要

PURPOSE: An optical gigabit Ethernet switch which provides an Internet group management protocol function for an HFC network IPTV service is provided to supply a stable packet network solution by loading a necessary QoS(Quality of Service) function for a TPS to a packet switching technology of a CTMS(Cable Modem Termination System) which is applied to a current optical network based on a DOCSIS1.0/2.0. CONSTITUTION: A network transmission and reception unit transmits and receives a packet by accessing a giga bite Ethernet, and a QoS logic unit discriminates a voice packet, an image packet and a data packet in a packet received through the network transmission and reception unit. The QoS logic unit provides the QoS proper to a corresponding packet. The memory unit temporarily stores the data or packet processed in the QoS logic unit.
