Simulation Based Routing Protocols Analysis - Essay Example

Most of the widely used routing protocol includes the Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), and the Interior Gateway Routing Protocol (IGRP). Enhanced interior Gateway routing Protocol is an advanced distance vector routing protocol that reduces routing uncertainty which developed after the re-arrangement of various computer network elements. Routers that operate through EIGRP involuntarily spread data packets to the interior gateway routing protocol by changing the 32-bit enhanced interior gateway to a 24-bit interior gateway. Since EIGRP uses a dual update algorithm (DUAL) its confluence is much faster. The time taken to transmit data packets through the telecommunication network from the source destination is from 65ms up to 185ms.

Open Shortest Path First (OSPF) developed by Interior Gateway protocol, conveys information in an automatic system. Different versions of OSPF include the OSPF version one and the OSPF versions two. OSPF has been widely used in large-scale network connections. Open Shortest path operates by acquiring information from the neighboring routers and then developing a path for the network. The schematic arrangement of the network establishes the routing mechanism on the internet layer. If there are changes in the network arrangement, the OSPF closes in on a new loop, by analyzing the shortest path for the different routers using the graph search algorithm with all positive path costs. The main advantages of the Open shortest path first are it can reduce router paths as well as configure an area by minimizing the size of a routing table. OSPF also supports various routes and lengths of an IP address.

Comparing the two routing protocols regarding end-to-end delay, throughput, and delay jitter, the end-to-end delay of EIGRP and OSPF is from 65 to 185 ms with a 15% network load. As seen from the graph below, when the background load is set to 40%, The EIGRPrisess to 200 ms while the OSPF rises to 4.4 seconds. With a higher background load, EIGRP and OSPF delay elevates to 600 seconds. Analyzing the graph, EIGRP's end-to-end delay has a superior dispatch than OSPF.
On determining the rate of transmission of the data packets through a network channel, the EIGRP network when compared to OSPF has a high output relative to input. Comparing the two loads with 10% and 70% load, EIGRP throughput is more when compared to OSPF. Thus it can be concluded that the EIGRP output relative to input is much higher than OSPF. This is attributed to the high levels of link snarl-up.

The dissimilarity of the received packets impedes due to network gridlock and wrong network configuration. Having an idea on that, using a 40% background load, EIGRP and OPSPF edginess elevates at 400 seconds. Boosting the background level to 60%, EIGRP dissimilarity is passably higher than OPSPF. In culminating, it is perceived OSPF network has more jitter than the EIGRP network.
In conclusion, OSPF's end-to-end delay is more than EIGRP's. This is attributed to the high rate of transmission of Data packets in the EIGRP network when compared to OSPF. Due to link Snarl-up, EIGRP has a higher output-input ratio than OSPF. Read More
