摘要： A frame forwarding apparatus connected between an ISP router and a plurality of subscriber terminals comprises a frame forwarding processing unit and a VLAN bundling table defining the correspondence of subscriber side line information with ISP router side line information and subscriber terminal's MAC address. The subscriber side line information includes a physical line number and a subscriber VLAN identifier, and the ISP router side line information includes a physical line number connected to the ISP router and a group VLAN identifier. By referring to the VLAN bundling table, the frame forwarding processing unit operates to convert a VLAN identifier given in a frame received from a subscriber terminal into a group VLAN identifier and to convert a VLAN identifier given in a frame received from the ISP router into a subscriber VLAN identifier, before forwarding the frame to its destination.

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： 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： In a configuration where a virtual storage array is formed in a physical storage array, if a physical storage administrator acquires a lock for all the physical storage arrays during update of information of multiple physical storage arrays, not only all the physical storage arrays but also all the virtual storage arrays formed therein cannot be manipulated while information update is executed. According to the present invention, when a virtual storage administrator executes change of configuration of the virtual storage array while the physical storage administrator is performing information update of all multiple physical storage arrays and management operation from the virtual storage administrator is not prohibited, the information of the changed configuration is stored in a temporary area of a configuration information database, and at the last of information update, the information of the temporary area is reflected to a normal area of the configuration information database.

摘要： Provided is a computer system including a host computer, a plurality of virtual storage systems coupled to the host computer, a storage system coupled to the plurality of virtual storage systems, and a management computer. The storage system includes storage areas provided as volumes to the host computer. Each of the virtual storage systems provides virtual volumes corresponding to the volumes to the host computer. The host computer disperses a plurality of data I/Os containing data to be written in one of the volumes to the virtual volumes of a plurality of paths reaching the one of the volumes at a determined ratio. The management computer calculates a threshold value of a performance value to be set in the virtual volume of each of the paths to determine whether to generate an alert based on the predetermined ratio. Thus, performance of the computer system is properly managed.
