Server Congestion Control And Reduction of Server Power Consumption With DPI Technology
Shin-ichi Kuribayashi · International journal of Computer Networks & Communications · 2015
Deep packet inspection (DPI) technology has conventionally been introduced for traffic monitoring, bandwidth control, access control of specific types of traffic, etc.As a new potential application of DPI technology, this paper proposes three promising approaches of network and server control with DPI technology, and presents implementation examples of two approaches.These approaches could simplify dramatically the conventional work load for system management and reduction of p ower consumption by servers and accelerate the control action.First, this paper proposes an example of server congestion control method, in which the DPI equipment estimates the CPU usage of each server by constantly monitoring the number of TCP live co nnections established by each server, and moves some of virtual machines on the congested server to other servers through remote control timely.Next, this paper proposes an example of reducing power consumption by servers, in which the DPI equipment constantly monitors the traffic sent or received in each area with multiple servers.Finally, the feasibility of the proposed approaches is demonstrated by an evaluation system with a real DPI equipment.
