Hybrid approach for performance enhancing proxies
First Claim
1. A method for operating a transparent performance enhancing proxy between a source device and a destination device, comprising:
- preserving, without translation, packet header information of a header for a packet received from the source device to be forwarded to the destination device;
during a transmission control protocol connection setup phase for the packet, preserving transmission control protocol connection semantics; and
after establishment of a connection between the source device and the destination device during the transmission control protocol connection setup phase as indicated by the transparent performance enhancing proxy receiving a synchronization acknowledgment from the destination device, locally terminating the connection at the transparent performance enhancing proxy and creating a connection from the source device to the transparent performance enhancing proxy and a connection from the transparent performance enhancing proxy to the source device.

Abstract
There are provided a transparent performance enhancing proxy, a method for operating a transparent performance enhancing proxy between a source device and a destination device, and corresponding computer program product. The method includes preserving, without translation, packet header information of a header for a packet received from the source device to be forwarded to the destination device. The method further includes during a transmission control protocol connection setup phase for the packet, preserving transmission control protocol connection semantics. The method also includes during a transmission control protocol data transfer phase for the packet, running a transmission control protocol by masquerading as the source device to the destination device and masquerading as the destination device to the source device to transmit the packet to the destination device with the preserved packet header information.

8. A computer program product for operating a transparent performance enhancing proxy, the computer program product comprising a computer readable non-transitory storage medium having program instructions embodied therewith, the program instructions executable by a processor comprised in the transparent performance enhancing proxy to cause the transparent performance enhancing proxy to:
-
preserve, without translation, packet header information of a header for a packet received from the source device to be forwarded to the destination device; during a transmission control protocol connection setup phase for the packet, preserve transmission control protocol connection semantics; and after establishment of a connection between the source device and the destination device during the transmission control protocol connection setup phase as indicated by the transparent performance enhancing proxy receiving a synchronization acknowledgment from the destination device, locally terminating the connection at the transparent performance enhancing proxy and creating a connection from the source device to the transparent performance enhancing proxy and a connection from the transparent performance enhancing proxy to the source device. - View Dependent Claims (9, 10, 11)

12. A transparent performance enhancing proxy for disposing between a source device and a destination device, the proxy comprising:
-
a processor for preserving, without translation, packet header information of a header for a packet received from the source device to be forwarded to the destination device; and a memory for storing a copy of the packet, wherein during a transmission control protocol connection setup phase for the packet, the processor preserves transmission control protocol connection semantics, and after establishment of a connection between the source device and the destination device during the transmission control protocol connection setup phase as indicated by the transparent performance enhancing proxy receiving a synchronization acknowledgment from the destination device, locally terminating the connection at the transparent performance enhancing proxy, wherein during a transmission control protocol data transfer phase for the packet, the processor running a transmission control protocol by masquerading as the source device to the destination device and masquerading as the destination device to the source device to transmit the packet to the destination device with the preserved packet header information. - View Dependent Claims (13)
