Patent ID: 7590629

Claim:
A method, comprising: receiving data arranged for transmission from a first device at an intermediate network device, said received data comprising synchronization related information, said synchronization related information being part of an end-to-end synchronization session operated between said first device and a second device for synchronizing data stored at said first device and said second device, at said intermediate network device, obtaining said synchronization related information from said received data; at said intermediate network device, parsing said synchronization related information for routing related information, wherein said routing related information comprises response address information indicating to transmit a response to said first device as recipient thereof, wherein said routing related information further comprises recipient address information indicating said intermediate network device as recipient of said synchronization related information; at said intermediate network device, processing said routing related information contained in said synchronization related information such that synchronization related information comprising processed routing related information is obtained; at said intermediate network device, arranging processed data comprising said synchronization related information with said processed routing related information; and transmitting said processed data from said intermediate network device to said second device, wherein said processing of said routing related information comprises: replacing said response address information indicating to transmit said response to said first device as recipient with response address information indicating to transmit said response to an intermediate network device as recipient of said synchronization related information, and replacing said recipient address information indicating said intermediate network device as recipient of said synchronization related information with recipient address information indicating said second device as an originally dedicated recipient of said synchronization related information so that the second device does not receive routing related information containing recipient address information indicating the intermediate network device as the recipient thereof.
