Zusammenfassung:PURPOSE: A network apparatus for guaranteeing quality of an IPTV service is provided to determine whether to supply an IPTV service in consideration of a redundancy bandwidth of a queue matched with a port for transmitting an IPTV service. CONSTITUTION: A protocol processing unit(22) detects a destination address and a source address from a service request packet delivered from a packet classifying unit. The protocol processing unit transmits the destination address and source address with a delivered port number. An accept controller(23) confirms a redundancy bandwidth of a queue corresponding to the port number delivered from the protocol processing unit. The accept controller compares the redundancy bandwidth with a bandwidth of a service requested by the IPTV terminal. The accept controller determines whether to supply a service.
