Abstract: Aspects of the invention provide systems and methods for reducing latency in TCP connections. A client computer may send a request for information to a server computer using TCP. In response, the server may transmit the information to the client device according to default TCP connection assumptions. The server may re-configure the TCP connection based on various network statistics identified by the characteristics of the exchange between the server and the client. The server may periodically provide the network statistics concerning the speed of the network connection between the server and the client to the client. This information may be stored in cache memory by the client device for later use. For example, the next time the client device requests information from the server, the server may request the cached network statistics. The server may use this information to determine how information should be transmitted to the client.

Abstract: A system and machine-implemented method for communicating with a client device. A server receives a first request by a client device via a first communication protocol, wherein the first request establishes a NAT binding which defines a communication path from a server to the client device. The server sends a response to the received first request via the first communication protocol, wherein the response is directed to the client device based on the NAT binding. The server determines that the response is unsuccessful in reaching the client device. In response to the determination, the server transmits a communication to the client device via a second communication protocol which is different than the first communication protocol, wherein the communication instructs the client device to re-establish the NAT binding.

Abstract: A system and method for facilitating packet loss recovery using an intermediary are provided. The system includes a first node configured to transmit a plurality of data packets, a second node configured to receive the plurality of data packets and a third node configured to act as an intermediary between the first node and the second node and is configured to receive one or more packets of the plurality of data packets transmitted from the first node to the second node before the one or more packets are transmitted to the second node, and determine if a packet loss event has occurred, wherein a packet loss event occurs if a first packet of the plurality of packets is lost during transmission from the first node to the second node and take an action with respect to the first packet if it determined that a packet loss event has occurred.
