Abstract :
In order to achieve good user experience, data center services usually operate under deadline constraints. Besides, data center services typically employ Partition/Aggregate algorithms which result in bursts of short query traffic with tight deadlines. This paper proposes a Deadline and Size aware TCP scheme (DSTCP) for datacenter networks, which adjusts the congestion window size of a flow according to its deadline and its size, as well as the dynamic congestion degree of network. Coexisting with TCP, DSTCP can achieve a high throughput and maintain a small queue at the same time. Due to the awareness of flow deadline and flow size as well as the gentle additive increase and back off mechanism, DSTCP can greatly reduce the number of deadline-missing flows.
