Abstract:
1. A network device comprising: at least one first receiver for receiving a first packet including first data and a first header from a first device, the first header including first information at a layer higher than an internet protocol layer, the first information including a sequence parameter; at least one first transmitter for transmitting a second packet in response to a reception of the first packet, the second packet including second data and a second header to a second device, which second header includes second information at the layer higher than the internet protocol layer, the second data being equal to the first data; at least one second receiver for receiving a third packet including third data and a third header from the second device, the third header including third information at the layer higher than the internet protocol layer; at least one second transmitter for transmitting a fourth packet in response to a reception of the third packet, the fourth packet including fourth data and a fourth header to the first device, which fourth header includes fourth information at the layer higher than the internet protocol layer, the fourth data being equal to the third data; at least one detector for detecting the sequence parameter; and at least one inserter for inserting an acknowledgement parameter in the fourth information of a fourth packet, said acknowledgement parameter being related to said sequence parameter and obtained from the third information of an earlier third packet; wherein the at least one detector and the at least one inserter are for manipulating the information of at least one header of at least one packet for improving a transport efficiency between the first and second devices.
