Abstract
Abstract
High throughput with minimum delay is the ultimate demand being required from any network. Traffic congestion is the major problem that deteriorates the performance of a given network. Although switches help to a large extent in improving the traffic efficiency, but this is not the case with large scaled networks (WAN for example). VLAN switches play important roles in further improvements of network performance. The available types are based on port number and the new versions are based on MAC address, both types suffer from lack of security. The proposed VLAN switch provides higher network security because it is based on a simultaneous port and MAC functions. This benefit justifies the slight reduction in the throughput-delay performances as compared with the other types.
