Performance Analysis and Functionality Comparison of FHRP Protocols

Abstract

In this era, every field requires high availability of network with the least probability of data loss. Therefore, redundancy should be involved as much as possible for network design. However, the high availability of network necessitates higher managerial and operational cost. Redundancy protocols substantially help to solve the problem. First Hop Redundancy Protocols (FHRPs) are implemented to overcome traffic loss from source to destination in network communications. The FHRP consists of different types of protocols. Each protocol has its own purpose and has its own advantages and disadvantages. These protocols assist specific association to successfully transmit the traffic from source to goal without loss of numerous packet. The FHRP includes different kind of protocols but contains three main protocols. in this paper evaluates three particular protocols of FHRPs, namely the Hot Standby Router Protocol (HSRP), Virtual Router Redundancy Protocol (VRRP), and Gateway Load Balancing (GLBP). In this paper, we evaluate the three FHRPs by using GNS3 tool. The performances of the three FHRP protocols are analyzed and their functionalities are compared.
