There can be a lot of QoS parameters that can improved in IP MPLS network Backbone such as bandwidth, CPU utilization, memory requirement, resources distribution and database optimization of each router in the backbone. This paper have optimized database of each router by involving DR/BDR election on each interface so that all involved routers use that elected DR router as to communicate hello packets instead of communicating with all routers and hence database size of each router will remain small and require less memory and CPU utilization over MPLS backbone. Simulation results have been verified using MRTG, Olive/Vmware using conventional IP, MPLS without TE and MPLS using TE capability.
