The high amount of small packets currently transported by IP networks results in a high overhead, caused by the significant header-to-payload ratio of these packets. In addition, the MAC layer of wireless technologies makes a non-optimal use of airtime when packets are small. Small packets are also costly in terms of processing capacity. This paper presents Simplemux, a protocol able to multiplex...
This paper proposes a method for optimizing bandwidth usage in Software Defined Networks (SDNs) based on OpenFlow. Flows of small packets presenting a high overhead, as the ones generated by emerging services, can be identified by the SDN controller, in order to remove header fields that are common to any packet in the flow, only during their way through the SDN. At the same time, several packets...
This paper explores the application of traffic optimization techniques, based on header compression and multiplexing, to the flow of ACKs sent by a TCP client when downloading a file. Significant compression rates can be obtained, but a multiplexing delay has to be added as a counterpart. The influence of this delay in TCP dynamics is explored by means of simulations including FTP flows sharing a...
This paper studies the optimization of the traffic of a P2P-TV application (SOPCast). First, a traffic characterization is deployed, and it is observed that the service generates a high rate of small UDP packet bursts between peers. Then, an optimization method based on header compression and multiplexing is used for sending together the packets with the same destination. Two multiplexing policies...
