Design and Performance Analysis of Complex Switching Networks through VLAN, HSRP and Link Aggregation

Dr.R. Vadivelu and Dr.S. Malathy


Abstract:

An overview of Layer 2-Switching and its load balancing technique is analyzed in this paper. The work elucidated here gives out the improvement of network performance by decreasing overhead. In this paper it shown that the aggregation and linking is done via Virtual Local Area network (VLAN). Devices of VLAN technology include host, switch and routers Switch used to connect multiple devices in the network. If multicast is not required by a host, then it will not send to that switch. Switch connects multiple hosts and establish suitable path over the network. Router enables VLAN sharing with external users. Sharing of information is possible in host, switch and router in the network. But quality of service (QoS) is not good as expected. To improve the QoS and performance, link aggregation is performed. Link aggregation is a technology used in combining (aggregating) multiple network connection in parallel to increase throughput beyond what a single connection could sustain and to provide redundancy in case one of the link failure. Layer 2 typically occurs across switch port which can be either physical port or virtual ones managed by VLAN, Hot Standby Router Protocol (HSRP) and link.

Keywords: VLAN, QoS, HSRP, Layer2 Switching, Link Aggregation.
