摘要： In a wide area Ethernet network, an edge side gateway (EGW) acquires layer 2 tunneling control information from an authentication server when a PADI is received from a user terminal, stores the correspondence between the source address of the PADI and the layer 2 tunneling control information in its management table, encapsulates the PADI in accordance with the layer 2 tunneling control information, and transmits the encapsulated PADI packet to the wide area Ethernet network. A core side gateway (CGW) having received the encapsulated PADI packet stores the correspondence between the tunneling control information and the source address extracted from the received packet in its management table, and forwards the PADI obtained by decapsulating the received packet to a broadband access server. Thereafter, each of the EGW and CGW forward received packets for the user after converting their format by referencing to the management tables.

摘要： A packet forwarding apparatus with a function of registering packet forwarding control information for each user terminal into a user management table during PPPoE connection and authentication phases in which the apparatus carries out predetermined communication procedures with each user terminal. During DHCP and IP forwarding phases following the authentication phase, the packet forwarding apparatus controls packet forwarding based on the user management table. Packets are forwarded in the form of PPPoE frame until the authentication phase is completed and packets are forwarded in the form of Ethernet frame in the DHCP and IP forwarding phases.

摘要： A packet transfer apparatus has a controller for controlling transmission of a PADO packet on the basis of the information that is previously set in the packet transfer apparatus in order that the PADO packet can be transmitted back to the terminals or a PADI can be discarded when the PADI packet sent from the terminals to the packet transfer apparatus does not have any Service-Name specified. In addition, another controller is used. This controller is provided so that, when a Service-Name that indicates the type of an offered communication service is specified in the PADI packet, it can judge whether the Service-Name is previously registered in a memory and decide to transmit the PADO packet to the terminal if the Service-Name is previously registered, but to discard the PADI packet if the Service-Name is not registered.

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： An IPv4-IPv6 multicast address translation table is dynamically created, so that it is unnecessary to register multicast servers in advance. When an IPv4 MC group address exists as a response of a DNS server to a DNS request of an IPv6 MC client or when an IPv6 MC group address exists as a response of the DNS server to a DNS request of the IPv4 MC client H1 to H4, DNS Proxy D3 requests an MC adaptive translator T1 to generate a virtual IPv6 MC group address or a virtual IPv4 MC group address, and the MC adaptive translator T1 generates a virtual IPv6 MC group address or a virtual IPv4 MC group address from an address pool, and also creates an MC address translation table, whereby the MC address translation of IPv4-IPv6 can be dynamically performed.
