Admission Control in Overloaded Web Servers
Kai Nan · Jisuanji gongcheng · 2007
It is becoming essential to protect Web servers against overload by providing admission control.This paper presents the design that performs admission control based on TCP header,and implements it in the Linux OS.There are six 1-bit flags in TCP header.The packets with flags,such as ACK packets,are more important than the application request packets.The experiments demonstrate its effectiveness,and show that the approach is efficient during overload.
