The present invention is generally directed towards a remote access architecture for providing peer-to-peer communications and remote access connectivity. In one embodiment, the remote access architecture of the present provides a method for establishing a direct connection between peer computing devices via a third computing device, such as a gateway. Additionally, the present invention provides the following techniques to optimize peer-to-peer communications: 1) false acknowledgement of receipt of network packets allowing communications via a lossless protocol of packets constructed for transmission via a lossy protocol, 2) payload shifting of network packets allowing communications via a lossless protocol of packets constructed for transmission via a lossy protocol, 3) reduction of packet fragmentation by adjusting the maximum transmission unit (MTU) parameter, accounting for overhead due to encryption, 4) application-aware prioritization of client-side network communications, and 5) network disruption shielding for reliable and persistent network connectivity and access.
1. A method for communicating a lossy protocol via a transport control protocol, the method comprising: (a) intercepting, by an agent executing on a device, a transport control protocol (TCP) packet to be transmitted by the device;(b) detecting, by the agent, that the transport control protocol (TCP
1. A method for communicating a lossy protocol via a transport control protocol, the method comprising: (a) intercepting, by an agent executing on a device, a transport control protocol (TCP) packet to be transmitted by the device;(b) detecting, by the agent, that the transport control protocol (TCP) packet has a payload comprising a lossy protocol;(c) communicating to a network stack of the device, by the agent responsive to the detection of the lossy protocol of the payload, an acknowledgement of receipt of the TCP packet prior to communicating the TCP packet from the device, wherein the acknowledgement of receipt of the TCP packet prevents the network stack from retransmitting the TCP packet; and(d) transmitting, by the agent, the TCP packet from the device. 2. The method of claim 1, wherein step (a) further comprises intercepting, by a shim of the agent at a layer of the network stack of the device, the TCP packet. 3. The method of claim 1, wherein step (b) further comprises determining, by the agent, that a header of the payload identifies a lossy protocol. 4. The method of claim 1, wherein receipt of the acknowledgement by the network stack prevents the network stack from executing a reliability algorithm for the TCP packet. 5. The method of claim 1, wherein step (c) further comprising communicating the TCP packet via one of a secure socket layer or a transport security layer tunnel. 6. The method of claim 1, wherein step (d) further comprises receiving, by an intermediary device intermediary to the device and a second device, the TCP packet and transmitting the payload of the TCP packet via the lossless protocol to the second device. 7. The method of claim 6, further comprising communicating, by the agent to the device, acknowledgement of receipt of the TCP packet prior to receipt of the TCP packet by the intermediary device. 8. A method for communicating a lossy protocol via a transport control protocol, the method comprising: (a) detecting, by an agent executing on a device, that a transport control protocol (TCP) packet, to be transmitted from the device, has a payload comprising a lossy protocol;(b) communicating, by the agent responsive to the detection of the lossy protocol of the payload, to a network stack of the device, a false acknowledgement of receipt of the TCP packet; and(c) transmitting, by the agent, the TCP packet from the device, the network stack of the device not performing a TCP reliability algorithm responsive to receiving the false acknowledgement. 9. The method of claim 8, wherein step (a) further comprises intercepting, by the agent at a layer of the network stack of the device, the TCP packet. 10. The method of claim 8, wherein step (a) further comprises determining, by the agent, that a header of the payload identifies a lossy protocol. 11. The method of claim 8, wherein step (b) further comprising communicating the false acknowledge of receipt prior to step (c). 12. The method of claim 8, wherein step (b) further comprising communicating the false acknowledge of receipt prior to actual receipt of the TCP packet by a receiver. 13. The method of claim 8, wherein step (c) further comprising communicating, the TCP packet via one of a secure socket layer or a transport security layer tunnel. 14. The method of claim 8, further comprises receiving, by an intermediary device intermediary to the device and a second device, the TCP packet and transmitting the payload of the TCP packet via the lossless protocol to the second device. 15. The method of claim 14, further comprising communicating, by the agent to the device, false acknowledgement of receipt of the TCP packet prior to receipt of the TCP packet by the intermediary device. 16. A system for communicating a lossy protocol via a transport control protocol connection, the system comprising: a device intermediary to a client and one or more servers, the device establishing a transport control protocol connection with the client;an application of the client transmitting lossy protocol data via the transport control protocol connection;an agent of the client detecting a transport control protocol packet is carrying the lossy protocol data and responsive to the detection issuing a false acknowledgement to a network stack of the client to prevent the network stack from executing a reliability algorithm for the transport control packet. 17. The system of claim 16, wherein the agent issues the false acknowledgement prior to the client transmitting the transport control protocol packet to the device. 18. The system of claim 16, wherein the agent issues the false acknowledgement prior to the device receiving the transport control protocol packet. 19. The system of claim 16, wherein the device receives the transport control protocol packet, strips the transport control protocol headers from the transport control protocol packet and transmits the lossy protocol data to a server.
