An Efficient and Implementation-Easy Etherent Local Area Network with Applications

Abstract

With increasing requirements in the network bandwidth of LAN we must do our best to improve the required network bandwidth by using lower cost. This paper presents a mechanism for establishing an efficient LAN by using intelligent switching hubs of easy implementation and low delay, where an LAN structure is constructed based on a full tree that the leaves represent user stations, the internal nodes represent intelligent switching hubs and the links between any pair of nodes ( or any pair of node and station ) represent full-duplex communication connections. Such an LAN including implementation-easy and low-delay intelligent switching hubs has been shown that it can allows simultaneous communications to exist in different parts of the network, and can isolate certain user stations or network so that the traffic congestion on an LAN can be reduced when more and more users add into the LAN. Moreover, since it is a tree structure and a switching network, it can provide more bandwidth for transmitting multimedia data by means of the priority scheme.
