摘要： A listening-or-viewing charge is differentiated with bit rates depending on distributed programs. A broadband access server for holding user channels by PPP and replicating and transferring multicast packets have a counter for counting the number of distributed multicast packets and the number of distributed bytes at each multicast group address. The counter values (byte counts and packet counts) when a user joins a multicast group and when the user leaves the multicast group and a multicast session ID containing a PPP user ID and a multicast group address are sent to a multicast accounting radius server. The multicast accounting server provides an accounting on a basis of the byte counts, the packet counts, or a bit rate.

摘要： In a PPP gateway apparatus comprising a plurality of line interfaces each accommodating one of access lines for connecting to client terminals and core lines for connecting to layer 2 frame forwarding apparatuses, a frame forwarding control table, and a frame processor for controlling frame forwarding, the frame forwarding control table includes table entries each indicating the correspondence of a PPP session number to a client MAC address and frame definition information for the core line, and the frame processor operates, based on the frame forwarding control table, to forward a PPP frame received from one of access lines to one of core lines after converting it into a layer 2 Ethernet frame and to forward a frame received from one of the core lines and destined for a particular client MAC address to one of access lines after converting it into a PPP frame.

摘要： An object of the present invention is to solve a problem that when multicast is utilized in a network configured with virtual routers, traffic in the relay network is increased. According to the present invention, the number of multicast packets via the relay network is reduced by performing a multicast packet transfer across the virtual routers within the same router. Specifically, it is allowed to register in a multicast routing table held by each virtual router, a line interface identifier of another virtual router as outgoing line interface information, whereby multicast packet transfer from a virtual router to another virtual router is made possible. In order to specify a virtual router to share the multicast packet, each virtual router holds information to specify a virtual router having a line interface to receive the multicast traffic indicated by the multicast group address.

摘要： An access network system connected to an ISP network including a subscriber authentication server comprised of a plurality of packet forwarding apparatuses each for connecting user terminals to an Internet network via the ISP network and an address pool management server having an address pool management table for holding, as a sub-address pool, a plurality of IP addresses usable over the ISP network. Each of the packet forwarding apparatuses acquires from the address pool management server an IP address to be allocated to the user terminal having requested connection to the Internet when the subscriber authentication server has succeeded in authentication of the user terminal.
