To reduce the overhead, the proactive caching schemes have been proposed. However, they require too many control packets delivering the security context information to neighbor access points. Our contribution＇ is made in two-fold： one is a significant decrease in the number of control packets for proactive caching and the other is a superior cache replacement algorithm.展开更多

It is one of the most important high speed LAN standard. The main characteristic for FDDI protecol is that it can support time-critical integrated applications such as voice and video transmission. This is based on two important theorems in the FDDI protocol. The purpose of this paper is to expand and prove these theorems when real-time signalling system is introduced into FDDI[1].展开更多
