Impact Of Mapping Priority Levels By Message Sizes On Homa Transport Protocol Performance In DCNs

This research work proposes powerful,efficient,and reliable Homa transport protocol modifications.We have introduced a novel,straightforward,and efficient algorithm of mapping priority levels by message sizes.Firstly,depending on incoming traffic,change the range of cutoff message size for unscheduled priority levels where we have used the explicit mechanism to determine cutoff range and mapping priority levels depending on workloads message sizes.Secondly,at the same time change the number of priority levels for scheduled and unscheduled packets where we have selected the best fraction to assign the priority levels.The proposed Homa transport modification is straight forward,less complex,and can be considered as a good alternative for algorithms of mapping priority levels by message sizes.Also the key idea of proposed mapping algorithm explicit assigning the priority levels directly depending on previous knowledge about workloads messages sizes.Except for our proposed amendments,our work has based on the same mechanisms as in the previous Homa work.As a result,our research work can very satisfactory and performance is relatively high.Moreover,our research work introduces sufficient knowledge about the impact of mapping priority levels by message sizes on Homa transport protocol performance in DCN.In simulation,our experimental results show that our proposed method has achieved satisfactory ability to improve Homa performance more under higher network load.At 90%network load,it improves better latency for short messages around 14 ?s,and minimizes the queue build up at receiver downlink side(between the TOR and receiver)?40%compared to Homa transport.Furthermore,at the same network load(90%)our proposed method delivers high bandwidth utilization up to 85%.
