摘要： A communication network management system has: a communication network including a plurality of nodes and a plurality of links connecting between the plurality of nodes; and a management computer connected to the plurality of nodes. A loop-shape communication route in the communication network is a loop route. The management computer transmits a frame to one node on the loop route. When receiving the frame, each node on the loop route forwards the received frame to a subsequent node along the loop route and, if a predetermined condition is satisfied, returns a response back to the management computer. The management computer determines whether or not a failure is occurring, based on reception state of the response.

摘要： Any packet loss is detected very quickly by means of only a series of sequence number in a multi-path environment where a transmitter and a receiver are connected to each other by way of a plurality of networks when no inversion of sequence arises in any of the networks. A communication apparatus includes a plurality of sequence buffers arranged at each network to accumulate packets until a sequence acknowledgement and an absence detecting section adapted to determine the occurrence of an absence of a packet when one or more packets are accumulated in all the sequence buffers. With this arrangement, the absence detecting section of the receiver monitors the packets staying in the sequence guaranteeing buffer arranged in each of the network, paying attention to the characteristic that packets are stored in the sequence buffers of all the networks when a packet loss takes place.

摘要： A TCP 2003 is terminated in an intermediate driver 2006 within a gateway device 20, a TCP 3003 is terminated in an intermediate driver 3006 within a gateway device 30, and a frame is transferred between the intermediate drivers with a method not causing a congestion control such as a UDP. Besides, an SSL session is constructed between an SSL 2002 and an SSL 3002, and upon completing construction of the session, a public key and a secret key are sent by means of an Ethernet frame from a processing speed acceleration engine control to a processing speed acceleration engine. Thus, the gateway device transfers the frame not through a CPU but by employing the processing speed acceleration engine within an NIC in later communication between a terminal 21 and a server 31.

摘要： A communication network management system has: a communication network including a plurality of nodes and a plurality of links connecting between the plurality of nodes; and a management computer that manages the communication network. The management computer has: a storage means in which a route information indicating a transfer route of frames in the communication network is stored; and a monitoring means configured to perform, based on the route information, transmission and reception of frames to and from the communication network. The monitoring means transmits a frame to the transfer route. Each of the plurality of nodes, when receiving a frame, not only forwards the received frame along the transfer route but also sends a reply to the management computer. The monitoring means identifies a location of failure occurrence on the transfer route, based on reception state of the reply from the plurality of nodes.

摘要： A communication network includes a plurality of nodes and a plurality of links connecting between the nodes. A management computer managing the communication network has a storage means, an entry control means and a monitoring means. A route information indicating a transfer route of frames in the communication network is stored in the storage means. The monitoring means performs, based on the route information, transmission and reception of frames to and from the communication network. The entry control means instructs each node to set up a forwarding table indicating a correspondence relationship between an input source and a forwarding destination of frames. More specifically, the entry control means instructs the each node to set up the forwarding table such that frames are forwarded along the transfer route indicated by the route information.
