摘要： A packet switching apparatus is constructed by a basic module disposed in the apparatus casing and an additional module disposed on the outside of the apparatus casing. The basic module has a common processing function irrespective of an access method and a service type, an interface accommodating lines to be connected to the Internet, and a plurality of interface boards conformed to a specific access method by which a hardware scale may be small. Only the basic module functions as a packet switching apparatus, and a processing function peculiar to each access method and service type is executed by the additional module.

摘要： An access node run as a packet switching apparatus enables IP connection services for a plurality of access methods; e.g., relatively low-speed IP connection, high-speed IP connection, and mobile network IP connection. By using this apparatus of the present invention, cost can be reduced and upgrading to advanced access networks and access services is easily carried out. Provision of the above access nodes implements upgrade-type network services common for diverse protocols. Each access node retains a pathfinding table to which input port, input tunnel identifier and input session identifier entries in a set are registered per session. When routing a packet, by looking up the set of these entries matching with the packet, the associated output port, output tunnel identifier, and output session identifier are obtained. After processing for the packet, appropriate for one of the plurality of access methods and network services, the node forwards the packet over the routed path.

摘要： In a packet forwarding apparatus including first line interfaces accommodating user terminals, a second line interface connected to a communication node on a session management apparatus side, and a protocol processing unit for updating a connection management table and a header information table when a specific session control packet is received from one of the first line interfaces. Upon receiving a real-time packet from one of the first line interfaces, if a table entry corresponding to the header information of the received packet has been registered in the connection management table, the control unit routes the received packet to one of the first line interfaces after rewriting its header information based on the header information table, and if the table entry has not been registered, the control unit routes the received packet as it is to the second line interface.

摘要： An LAC manages multicast destinations, and forms and distributes copies of the multicast packets. An L2TP tunnel and an L2TP session are formed between LAC 1-i and LNS 2-i, and LNS 2-i is connected to network NW2 such as the Internet. Data is transferred between a subscriber and the network through the L2TP connection. LNS 2-i and sever S1 are connected through network NW2 which has routers. A packet transfer apparatus enables LAC 1-i to manage subscriber information and to form and distribute copies of the packets to the subscribers when server S1 on network NW2 distributes multicast packets of a program or the like to the subscribers.

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.
