摘要： A TCP communications performance measuring device 2 obtains an effective bandwidth (a transfer speed) representing performance in TCP communications, wherein performance indexes or both of a round trip time and a maximum segment size which are obtained based on TCP communications variable-length packets transmitted and received pursuant to a TCP (Transmission Control Protocol) defined as protocol of a transport layer of the OSI Reference model, and any one of an average congestion window size, a packet discard rate and a packet discard event rate. The measuring device 2 therefore includes a packet monitoring unit, a performance index detecting unit 22, a session management unit 23, a session management table 24 and a performance calculating unit 25. The measuring device 2 is capable of measuring the performance in the TCP communications on a communications route of a network without specially transmitting the multiplicity of measurement-oriented packets to the network.

摘要： When service is allocated to a server of the other network on the basis of load information, a packet from a client is transferred as a transfer packet to the other wide area load distribution apparatus. The other wide area load distribution apparatus fetches the client packet from the transfer packet and converts its destination from a transferor address Lx to a server address S and its sender from a client address C to a self address Ly for sending to a server. Upon a reception of a response server packet from the server, the destination is converted from the self address Ly to the client address C and the sender is converted from the server address S to the transferor address Lx for the relay to the client.

摘要： A relaying apparatus comprises a client terminal, many server terminals connected via network to the client terminal, a DNS responding device which accepts a DNS inquiry from the client terminal via a client-side DNS device, and one path load measuring device for each of the server terminals which measures a load in the communication path up to the client-side DNS device. The DNS responding device distributes a work load by routing a service request from the client terminal to any one of the server terminals based on the measurement result (i.e. route load).
