System and method for a TCP mapper

A method for congestion control of traffic in a network that uses Transmission Control Protocol (TCP), wherein said traffic includes one or more incoming TCP traffic flows, and that includes a plurality of TCP congestion control programs and at least one TCP congestion control unit, each of the at least one TCP congestion control unit running one of said plurality of TCP congestion control programs, said method comprising:

• mapping a first incoming TCP traffic flow, wherein said first incoming TCP traffic flow originates from a TCP sending host, to a first of said plurality of TCP congestion control programs using a TCP mapper, wherein said mapping is based on a plurality of
• (a) the type of application program from which the first incoming TCP traffic flow originated,
• (b) the type of network for which the first incoming TCP traffic flow is destined,
• (c) parameters related to network performance, (d) network constraints,
• (e) source of the first incoming TCP traffic flow, and
• (f) destination of the first incoming TCP traffic flow;
• and
• wherein said TCP mapper is connected to said at least one TCP sending host over the network, and operates in a single-ended mode without a corresponding TCP mapper connected to the at least one receiving destination.

A method for congestion control of traffic in a network that uses Transmission Control Protocol (TCP), wherein said traffic includes one or more incoming TCP traffic flows, and that includes a plurality of TCP congestion control programs and at least one TCP congestion control units, each of the at least one TCP congestion control unit running one of said plurality of TCP congestion control programs, said method comprising:

• mapping a first incoming TCP traffic flow, said first incoming TCP traffic flow originating from a TCP sending host from said one or more incoming TCP traffic flows to a first of said plurality of TCP congestion control programs using a TCP mapper, wherein said mapping is based on parameters related to network performance;
• said mapping further comprising
• analyzing measurements of said parameters related to network performance, wherein said measurements are performed by at least one of the TCP mapper and external sensors,
• performing heuristics comprising
• determining presence and persistence of congestion, and
• identifying the cause of a packet loss event based on the determining of presence and persistence of congestion, wherein said identifying comprises correlating the packet loss event to one or more determined periods of persistent congestion;
• and
• tuning at least one parameter of said first TCP congestion control program based on results of said one or more heuristics.

A system for congestion control of traffic in a network that uses Transmission Control Protocol (TCP), said traffic comprising a plurality of incoming TCP traffic flows originating from a plurality of TCP sending hosts, said system comprising one or more TCP mappers, wherein each of the one or more TCP mappers receives one or more of the plurality of incoming TCP traffic flows;

• wherein each TCP mapper is associated with at least one TCP congestion control unit, each of the at least one congestion control unit running one of a plurality of TCP congestion control programs, and wherein each TCP mapper determines which of the plurality of TCP congestion control programs to map the one or more received incoming TCP traffic flows to, said determining based on at lest one a plurality of
• (a) the type of application program from which the incoming TCP traffic flow originated,
• (b) the type of network for which the incoming TCP traffic flow is destined,
• (c) parameters related to network performance
• (d) network constraints,
• (e) source of the incoming TCP traffic flow, and
• (f) destination of the incoming TCP traffic flow, and maps the one or more received incoming TCP traffic flows to one of said at least one associated TCP congestion control unit based on the determined TCP congestion control program, and
• further wherein each TCP mapper is connected to at least one TCP sending host, and at least one of the one or more TCP mappers is connected to only one TCP sending host.
