Embodiment Construction

[0025] In the network depicted in Fig. 1, a client terminal 107 is connected to a first digital subscriber line access multiplexer (DSLAM) 105 via an asymmetric digital subscriber line (ADSL). Similarly, clients 108 and 109 are connected to the second DSLAM 106 via respective ADSL loops. This is the access portion of the network shown in Figure 1. In the aggregated part of the network, the first and second DSLAMs are connected to an Ethernet switch 104 . The Ethernet switch is coupled with the IP backbone 101 through the second Ethernet switch 103 and the IP edge router 102 .

[0026] Figure 1 further illustrates a number of aggregated TCP streams or TCP aggregated tunnels operating in accordance with the present invention. The first aggregated TCP flow 111 is a user-to-DSLAM tunnel between the client 108 and the DSLAM 106 . All TCP flows between the user or client 108 and the DSLAM 106 are aggregated into a single, aggregated TCP flow, such as a TCP Fast flow. The TCP hos...

Abstract

A sending transmission control protocol (TCP) host is used in a first network node (106) to transmit TCP flows over a network segment to a receiving TCP host in a second network node (104). The sending TCP host comprises a TCP convergence module for aggregating all TCP flows through the network segment between the first network node (106) and the second network node (104) into an aggregate TCP flow (112). The receiving TCP host comprises a TCP convergence module for disaggregating the TCP flows from the aggregate TCP flow (112).

Description

technical field [0001] The present invention generally relates to the efficiency of transporting Transmission Control Protocol (TCP) streams over a network segment between a first network node and a second network node, each of which incorporates a TCP host. A TCP host can be a TCP client, a TCP server, or a TCP proxy. A TCP proxy is a server that acts as an intermediary between a client and another server called a destination server. Typically, a TCP client establishes a connection or stream to a TCP proxy server, which then establishes a connection to another TCP proxy server or destination server. Thus, the TCP proxy server terminates the TCP connection on one end and initiates a connection to the other end. The first and second network nodes can be any type of network equipment, including but not limited to: user terminals, such as digital subscriber line (DSL) modems, set-top boxes (STB), optical network terminals (ONT); access nodes, such as digital Subscriber Line Ac...
