Application performance improvement with application aware DPN switches

Large scale applications in data centers are composed of computers connected with a network. Traditional network switches do not perform routing based on packet contents. Thus, packets cannot be transmitted to the optimal computer for the request which is written in the packet payload. On the other hand, Deeply Programmable Network (DPN) switches can completely analyze packet payloads and perform routing based on their contents. In this paper, we focus on packet routing based on Deep Packet Inspection (DPI), i.e. analyzing packet payload, using DPN switches, and discuss performance of applications on a network using application aware DPN switches. We introduce application aware network and propose a method for improving application performance with DPN switch support. We evaluate our method with the several applications and show that our method can increase application performance.
