Dynamic Time Sync Reference Load Balancing In Virtual Router Redundancy Protocol
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 2, Issue 5
Abstract
In this paper, we discuss on Dynamic Time Sync Reference Load Balancing technique to enhance the Virtual Router Redundancy Protocol with Dynamic load balancing feature to utilize the redundant VRRP Backup device, inorder to share the traffic load. Virtual Router Redundancy Protocol acts as default gateway for the hosts on the shared Ethernet segment. VRRP protocol does not support the feature of load balancing for both the incoming and outgoing traffic. In this case, the Master VRRP device monitors the duration of the incoming traffic from a particular Virtual Local Area Network (VLAN) segment and redirects the traffic to the Backup VRRP device incase if the Master VRRP device still has the existing session based on the duration of the flow of traffic and the number of session through the Netflow cache database. While implementing Dynamic time sync reference Load Balancing mechanism, the Master VRRP device redirects the traffic to Backup VRRP device through the ICMP Redirect message, incase there is an current session going through the Master VRRP device by dynamically monitoring the Active Flow per Second parameter information through the Netflow cache information through the Layer 3 switch thereby achieving the Dynamic Load Balancing feature with the use of existing Active Flow per Second timers to dynamically share the traffic load between the Master VRRP device and the Backup VRRP device.
