Efficient quality of service-aware packet chunking scheme for machine-to-machine cloud services

摘要

With the recent advances in machine-to-machine communications, huge numbers of devicesrnhave become connected and massive amounts of traffic are exchanged. Machine-to-machinernapplications typically generate small packets, which can profoundly affect the network performance.rnNamely, even if the packet arrival rate at the router is lower than the link bandwidth,rnbits per second, it can exceed the router forwarding capacity,which indicates the maximum numberrnof forwarded packets per second. This will cause the decrease in the network throughput.rnTherefore, eliminating the packets per second limitation by chunking small packets will enablernmachine-to-machine cloud services to spread further. This paper proposes new packet-chunkingrnschemes aimed at meeting both application requirements and improving achievable routerrnthroughput. In our schemes, multiple buffers, each of which accommodates packets classifiedrnbased on their delay requirement, are installed in parallel. Herein, we report on analysis of therntheoretically performance of these schemes, which enabled us to derivesomeimportant features.rnWe also propose a scheme whereby a single chunking buffer and parallel multiple buffers werernarranged in tandem. Through our simulation and numerical results, we determined that thesernschemes provide excellent performance in reducing the number of outgoing packets from thernrouter while meeting various delay requirements.
