摘要： Upon receiving a connection request from a terminal, a packet transfer apparatus registers information on the terminal with a memory and forwards information necessary for the authentication of the terminal and an authentication request to an authentication server. The apparatus then receives authentication permission and a multicast group address list associated with the terminal that has made the connection request from the server. The apparatus then associates the multicast group address list received with the terminal information stored in the memory for registration. Upon receiving a participation request from the terminal, the apparatus determines whether or not the group address contained in the participation request is present in the list in the memory. If the group address is present in the list in the memory, the apparatus permits the delivery of a packet to the terminal from a content delivery server and transmits the packet to the terminal.
摘要翻译：在从终端接收到连接请求时，分组传送装置向存储器登记终端的信息，并且向认证服务器转发终端认证所需的信息和认证请求。然后，该装置接收到从服务器发出连接请求的与终端相关联的认证许可和多播组地址列表。然后，该装置将接收到的多播组地址列表与存储在存储器中的用于注册的终端信息相关联。在从终端接收到参与请求时，设备确定参与请求中包含的组地址是否存在于存储器中的列表中。如果组地址存在于存储器中的列表中，则该设备允许从内容传送服务器向终端传送分组，并将该分组发送到终端。

摘要： A packet transfer apparatus which can switch a communication path for each of a plurality of users using the same L2TP tunnel is provided. Packet transfer apparatuses terminating L2TP contain a table specifying a flow threshold level and a priority level of each subscriber; the amount of packet flow of each subscriber is measured in accordance with the information in the table; if the threshold level is exceeded, the packet communication path is switched in accordance with the priority level specified for each subscriber. The OSPF protocol is used to manage the path information, and the information of a plurality of paths to a destination is stored in a path management table. The path is switched by specifying destination routers with the source routing option in the IP header of a packet after L2TP encapsulation.

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： A spanning tree is formed for each of MST (Multiple Spanning Tree Protocol) instances defined by a VLAN ID and a COS value. Each terminal apparatus specifies the COS value corresponding to the TCP/UDP port number of a Ethernet frame to be transmitted, based on a conversion table indicating the correspondence of a TCP/UDP port number to a COS value and sets the specified COS value to the header of the Ethernet frame. Each of bridges in the transit network specifies the MST instance identifier of a received frame based on a conversion table indicating the correspondence of the MST instance identifier to the combination of a VLAN ID and a COS value and forwards the received frame in accordance with the spanning tree having the specified MST instance.

摘要： Any or unique VLAN ID is dynamically assigned to a user terminal connected to a network, and communication by the assigned VLAN ID is enabled. A connection request from a user terminal is directed to L2GWs by a tagged VLAN frame having a common VLAN ID on the network. The L2GWs determine whether the connection request can be met, obtain a VLAN ID that can be assigned to the user terminal from a VLAN ID management server, configure themselves to communicate by the assigned VLAN ID, and report the VLAN ID to the user terminal. The user terminal performs subsequent communication by the reported VLAN ID. L2SWs monitor communication between the user terminal and the L2GWs and configure themselves to allow communication between the user terminal and the L2GWs by the VLAN ID assigned to the user terminal.

摘要： In a network having an L2SW in which uplink VLAN is set, a transfer delay of a voice call packet is prevented. In a process of establishing a session between terminals (5), a packet transfer device (1) stores information capable of specifying a sending terminal (5-1) and a receiving terminal (5-2) and a correspondence relation (user connection information) to a connection port into a table. A SIP message of a session control packet communicated between the terminals (5) is snooped, and a destination IP address, a transmission source IP address, a destination port number, a transmission source port number, a connection port etc. are stored into the table. In a case where an RTP packet as voice data is received after the session is established, the packet transfer device (1) performs a loopback transfer or transfers it to an uplink port in accordance with the table.

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： 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.
