MPLS NETWORK AND TRAFFIC CONTROL METHOD UTILIZED THEREFOR

摘要

This MPLS network has: IP communication control devices (1, 2) that include a means for identifying a TCP connection request transmitted from a client terminal; and a communication management device (4) that includes a means for calculating a band for a TCP connection that requires a broad band on the basis of the identification result of the TCP connection request and a means for selecting and transmitting an LSP with which the calculated band can be secured for an end-to-end connection. Consequently, an MPLS network that is capable of securing the required band for the TCP connection between the MPLS PE router and the MPLS PE router on the MPLS network so as to reliably avoid discarding of packets due to network congestion and improving the quality of TCP communications is provided.
