Abstract

we tend to discuss on Dynamic Time adjust Reference Load equalization technique to reinforce the Virtual Router Redundancy Protocol with Dynamic load equalization feature to utilize the redundant VRRP Backup device, in order to share the traffic load. Virtual Router Redundancy Protocol acts as default entry for the hosts on the shared Ethernet segment. VRRP protocol doesn't support the feature of load equalization for each the incoming and outgoing traffic. during this case, the Master VRRP device monitors the length of the incoming traffic from a selected Virtual native space Network (VLAN) section and redirects the traffic to the Backup VRRP device incase if the Master VRRP device still has the existing session support ed the length of the flow of traffic and the variety of session through the Netflow cache information. whereas implementing Dynamic time correct reference Load equalization mechanism, the Master VRRP device redirects the traffic to Backup VRRP device thro ugh the ICMP airt message, encase there's an current session browsing the Master VRRP device by dynamically monitoring the Active Flow per Second parameter info through the Net flow cache data through the Layer three switch thereby achieving the Dynamic Load equalization feature with the utilization of existing Active Flow per Second timers to dynamically share the traffic load between the Master VRRP device and also the Backup VRRP device.
