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: Systems, methods, and machine-readable media for low latency server-side redirection of User Datagram Protocol (UDP)-based transport protocols traversing a client-side Network Address Translation (NAT) are provided. At a first server, a request for directing a data resource to a client may be received. The request may be received from the client or a back-end server trying to push the data resource to the client. The first server may lack the data resource or the resources to provide the data resource to the client. A second server may be determined for responding to the request. The request may be redirected to the second server. The first server may provide for the second server to connect to the client and directly respond to the request. The second server may have not been previously connected to the client.

Abstract: A system and method is disclosed for moving between delay sensing and packet loss based congestion control states. In connection with communicating over a network by sending and receiving data, one or more network devices automatically selects between a first and a second congestion control state for the sending and receiving of the data based a predetermined algorithm. The devices move between the first and the second congestion control states to maintain a bit rate associated with the sending and receiving at a predetermined threshold according to the predetermined algorithm.
