Write a 2 pages paper on routing protocol. Due: Routing Protocol Introduction Routing protocol particularize how data packets between computers is forwarded through circulating information between different nodes on a telecommunications network. In the telecommunications network, different routers operate through recalling the earlier networks specified onto it. After recalling the previous network, the routing protocol then shares the information among the routers on the same path then to the routers across the entire network (Jaffar, 2007)

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 which reduces routing uncertainty which developed after re-arrangement of various computer network elements. Routers which operate through EIGRP involuntarily spread data packets to the interior gateway routing protocol by changing the 32 bit enhanced interior gateway to 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 neighbouring routers 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 of 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 configuring an area through minimizing the size of a routing table. OSPF also supports various routes and length 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 65ms to 185 ms with a 15% network load. As seen from the graph below, when the background load is set to 40%, The EIGRP raises to 200 ms while the OSPF rises to 4.4 seconds. With a more background load, EIGRP and OSPF delay, elevates to 600 seconds. Analyzing the graph, EIGRP end to end delay has a superior dispatch than OSPF.

On determining the rate of transmission of the data packets through a network channel, 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 impede happen 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 EIGRP network.

In conclusion, OSPF end to end delay is more than EIGRP. This is attributed to the high rate of transmission of Data packets in EIGRP network when compared to OSPF. Due to link Snarl-up, EIGRP has a higher output input ratio than OSPF.
