Abstract:
1. A server for forwarding data from a first network to a second network, the server comprising: a first interface module for sending data to and receiving data from said first network; a second interface module for sending data to and receiving data from said second network; a segmenting module segmenting each first data transmission unit (DTU) of a first type received from said first network into at least two second DTUs of a second type, said segmenting module receiving first DTUs from said first interface module and said segmenting module sending said at least two second DTUs and at least one duplicate second DTU to said second interface module for transmission to said second network; a reassembly module reassembling first DTUs from second DTUs and duplicate second DTUs received from said second network, said reassembly module determining if a predetermined total number of second DTUs and duplicate second DTUs have been received to reassemble a first DTU, said reassembly module sending reassembled first DTUs to said first interface module for transmission to said first network, said reassembly module receiving said second DTUs and duplicate second DTUs from said second network interface, and, in the event the predetermined total number of second DTUs and duplicate second DTUs is not received by said reassembly module, said reassembly module transmits a retransmit request to a sender server by way of said second interface module.
