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： 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： 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.
摘要翻译：动态创建IPv4-IPv6组播地址转换表，无需事先注册组播服务器。当IPv4 MC组地址作为DNS服务器对IPv6 MC客户端的DNS请求的响应而存在时，或者当IPv6 MC组地址作为DNS服务器对IPv4 MC客户端H 1至 H 4，DNS代理D 3请求MC自适应转换器T 1生成虚拟IPv6 MC组地址或虚拟IPv4 MC组地址，MC自适应转换器T1生成虚拟IPv6 MC组地址或虚拟IPv4 MC组地址池，并创建一个MC地址转换表，从而可以动态地执行IPv4-IPv6的MC地址转换。

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 1P 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： An IP address provision request issued from a client terminal according to the DHCP protocol is transferred to a DHCP server, and an application for provision of an IP address is received. At this time, a packet transfer system stores pieces of information on the client terminal (IP address and MAC address) in a memory unit. Moreover, the client terminal or the packet transfer system itself broadcasts an ARP request. Pieces of information on the client terminal (IP address and MAC address) contained in an ARP packet are also stored in the memory unit. If the stored IP addresses contained in the DHCP and ARP packets respectively agree with each other, packets addressed to the client terminal that has transmitted the ARP packet are filtered in order to decide whether the packets are allowed to pass through the port.

摘要： To implement a calling party number anonymous service in an IP telephone service. An IP telephone terminal adds the setting of requesting a Pool IP address along with a normal IP address to a REGISTER message directed from the IP telephone terminal to an SIP server and requests the assignment of a temporary IP address if receiving an anonymous call incoming request message. The SIP server makes the temporary assignment of the Pool IP address and notifies the temporary IP address to a called party IP telephone terminal by adding it to an INVITE message, if the called IP address of the anonymous call incoming request INVITE message is the IP telephone terminal. The called IP telephone terminal receiving the assignment of the temporary IP address can make the connection, communication and disconnection processes employing the temporary IP address as the self IP address in the following dialog.

摘要： The access server receives an authentication packet including an authentication result, a port change setting information, a port change time, a filtering setting information and a filtering time from the authentication server. The access server stores the respective information in the authentication packet into a memory. The access server refers to the memory, and in the case where the port change setting information on an arbitrary user identifier is set to perform port change, when it becomes the port change time, the access server changes the output destination of a packet from a user terminal to, for example, a proxy server B from a proxy server A. Besides, in the case where the filtering setting information on an arbitrary user identifier is set to perform filtering, when it becomes the filtering start time, the access server performs filtering on the port to which the user terminal is connected.
