Performance Analysis and Route Optimization: Redistribution between EIGRP, OSPF & BGP Routing Protocols

Routing is the process of data path selection of IP networks. Routers perform path selection on the basis of routing tables stored in their memory. Routing table contains IP routes for route transformation via the best path in the networks. Service providers use different routing protocols in their enterprise networks. These routing-protocols have the limitation of non-convergence in the networks. Route redistribution is the technique which overcomes this limitation. Due to this technique, service providers can get optimized communication with IP networks where multiple routing protocols are being used. This research article focuses on the performance and redistribution of different routing protocols in medium or enterprise IP networks. A simulated network model is established in GNS3 simulator. Five Cisco-7200 series routers and a switch is used in this simulated topology. All these routers are directly connected with each other via serial links. Routing protocols EIGRP, OSPF and BGP are used in this topology and then configured route redistribution on these routers. Different types of data traffic are generated and passed through the network in order to analyze network convergence, throughput and packet delay by the use of software wire shark network analyzer and debug command. EIGRP is better in convergence and through put whereas OSPF is better in packet delay.

Performance Evaluation in Dynamic Routing Protocol Streaming Video

The simulation results and comparative performance analysis of routing protocols EIGRP and OSPF, within streaming video in real time. Developed a simulation tool for the design and modeling of local and global networks, computer systems, applications and distributed systems, OPNET. Network models were created based on the routing protocols EIGRP and OSPF. Evaluation of these routing protocols has been done on the basis of quantitative indicators such as the convergence time delay variation of packets through the delay and bandwidth. Two scenarios were considered network consisting of six interconnected subnetworks, where routers subnets configured to work with EIGRP and OSPF routing protocols. The results indicate that the routing protocol EIGRP, streaming video applications in real time, is more efficient than the routing protocol OSPF.

Opnet Based simulation for route redistribution in EIGRP, BGP and OSPF network protocols

Route redistribution (RR) has become an integral part of IP network design as the result of a growing need for disseminating certain routes across routing protocol boundaries. While RR is widely used and resembles BGP in several non-trivial aspects, surprisingly, the safety of RR has not been systematically studied much by the networking community. This paper presents the study of the model in opnet for understanding the route redistribution in a network comprising of different AS. The behaviour of routing protocols EIGRP, OSPF, BGP is studied. The performance of each routing protocol is different from each other. Each of them has different architecture, adaptability, routing algorithms, processing delays and convergence capabilities. Among different routing protocols, EIGRP and OSPF have been considered as the pre-eminent routing protocols for the real -time application. To select a right protocol, several parameters such as network convergence time, bandwidth, scalability are considered. This paper reports a simulation based study between EIGRP, BGP and OSPF. In order to evaluate the performance of EIGRP and BGP three network scenarios are configured viz route redistribution, FFC with route redistribution and to fasten the BGP process the header changes are done.

Assessment of Dynamic Routing Protocols for Increased Number of Workstations

Paper describe the analysis of dynamic routing protocols EIGRP, OSPF and their combination i.e. OSPF-EIGRP for the scenario which have increasing number of workstations from 3 to 50 in steps working on three dissimilar applications (Database, E-mail, and HTTP). Initially three individual workstations were considered which then replaced by LANs of 10, 25 and 50 in order to appraise the recompense of one scenario over the other. Simulation is carried out with the help of Optimized Network Engineering Tool (OPNET) which gives the better edge over the other network simulation tools available. The assessment is based on the two parameters namely E-mail Upload Response Time and HTTP Page Response Time. The results concluded that overall best performance can be achieved with the help of EIGRP protocol for the given scenario.
