Performance Evaluation of OSPF and ISIS Routing Protocols using DualStack Mechanism ABSTRACT ○Problem Statement: The Aim Of This Dissertation Is To Investigate, Evaluate the Performance of Two Most Popular Linkstate Routing Protocols(OSPF ISIS) When Configured In IPv4/IPv6 Dualstack Enterprise Networks.Continued .... The aim of the work was to provide proofbased advice for selecting the protocol that offers optimal performance in business enterprise networks. With Respect To Several Performance Metrics: (1) Jitter (2) Packet End To End Delay, (3) Throughput Simulation Tool Used: Opnet Modeler 16.0Thesis Aims and Objective 1.) Firstly Discuss In More Detail The Dual Stack Over An IP Network And The Possible Subservices Offered With The Required Qos. 2.) Thesis Aims To Provide Tangible Performance analyzing Results Regarding Network Metrics: 1.) Throughput 2.) Endtoend Delay 3.)

Comparing And Analyzing Its Performance Has Been Tried Under Various Scenarios, Including Well Accepted Models By Dualstack Enterprise Network Applying Different Mechanisms.IPv4IPv6 Dual Stack Support IPv4 only Support dual IPv4 and IPv6 In Dual Stack, Both protocols IPv4 and IPv6 run parallel on an equivalent network infrastructure don’t need encapsulation of IPv6 inside IPv4 and vice versaDual – Stack…. Advantages ○ Simple Disadvantages ○ Easy to understand and  Need for IPv4 addresses on configure every node. ○ Inexpensive  Extra address advertisement ○ Scalable to DNS. ○ Lower packetloss rates  More CPUmemory overhead. ○ Higher throughput rates . ○ Direct communication between nodes . ○ Recommended solution .DualStack Router Structure and Function ○ A dualstack router holds both IPv4 and IPv6 routing tables which are used according to the IP version that the router is about to forward.Open Shortest Path First (RFC 1247) Link state routing protocol that was developed by IETF in 1987 ○ Interior routing protocol, its domain is also an autonomous system ○ Special routers (autonomous system boundary routers) or backbone routers responsible to dissipate information about other AS into the current system. ○ Divides an AS into areas ○ Error Handing Capability ○ Fast loop less convergenceOSPF (type of links)ISIS (Intermediate System to Intermediate System Routing Protocol) ○ It is also a linkstate routing protocol with several similarities with OSPF protocol, such as the use of the same SPF algorithm. ○ It was defined by ISO (International Organization for Standardization) ○ ISIS is based on the primer OSI (Open System Interconnection) reference model. ○ It provides rapid Convergence when a topology changes. ○ Minimizes the routes and reduces the size of routing table. ○ Low bandwidth utilization ○ Multiple routes are supportedSimple ISIS NetworkSimulation ScenarioLiterature Review A. Basu et al., studies the stability of the OSPF protocol under steady state and with interferences. In this study we will see what effects are given by the TE (Traffic Engineering) extensions on the stability of a network when OSPF is running. OSPF TE extensions provide mechanisms for ensuring that all network nodes have a consistent view of the traffic parameters associated with the network. The authors also analyze whether it is possible to accelerate the convergence time of the network, analyzing the Hello packets and the number of route flaps. B. Albrightson et al. They explain that EIGRP is a protocol based on a hybrid routing algorithm, sharing some properties of distance vector and link state algorithms. This protocol is the first Internet protocol that addressed the loop problem. Other aspects which shows are the type of metrics, the transport mechanisms and the methods used to discover the networks, among other features.Continued……… D. Pei et al. show the design and development of a method for detecting RIP routing updates. Specifically, RIPTP protocol is presented. It uses hop count as routing metric. The authors emphasize its efficiency, simplicity, low operating cost and compatibility with the standard RIP. In order to assess the design efficiency, they show a series of experimental simulations to demonstrate that it is possible the improvement of fault detection in routing protocols. They particularize these evidences with RIP.IPv4 Throughput (TCP Traffic)OSPF IPv4 Clients EndtoEnd Delay (TCP Traffic)ISIS IPv4 Clients EndtoEnd Delay (TCP Traffic) OSPF IPv4 Clients EndtoEnd Delay Variation (TCP Traffic) ISIS IPv4 Clients EndtoEnd Delay Variation (TCP Traffic)conclusion ○ ISIS dominated over OSPF on both TCP and UDP traffic experiments. ○ ISIS achieved 58 higher throughput for IPV6 clients. In terms of end to end delay, jitter, OSPF and ISIS seems almost equally effective for IPV4 and IPV6, TCP UDP. ○ At last OSPF performs slightly better for TCP traffic and ISIS perform slightly better for UDP traffic.References ○1 Dooley, M. and Rooney, T.
