INTERIOR GATEWAY PROTOCOL ROUTING PERFORMANCE COMPARISON OF THE VIRTUAL PRIVATE NETWORK BASED ON MULTI PROTOCOL LABEL SWITCHING AND DIRECT-LINK BACKUPSED ON MPLS AND DIRECT-LINK BACKUP

The stability and convergence time become an essential factor in network availability performance. Multiprotocol Label Switching (MPLS) is one of the Virtual Private Network (VPN) technologies that can support the quality of communication media on the high-speed backbone network. Therefore, it is necessary to determine the proper protocol routing in espousing VPN technology based on MPLS supported by direct-link backup to improve network availability in the Data Center. The purpose of this study is comparing the convergence time and Quality of Service (QoS) among the three IGP protocols routing, namely Routing Information Protocol version 2 (RIP), Open Shortest Path First (OSPF), and Enhanced Interior Gateway Routing Protocol (EIGRP) based on two autonomous system number using Ring topology design between Data Center and DRC. Network scenario is created using the Graphic Network Simulator (GNS3) application to measure convergence time and QoS parameters of the three protocols routing and the use of MPLS-TE and RR in enhancing MPLS backbone performance. The results revealed that QoS in the three protocols routing has a good quality level according to TIPHON’s standard with the number of indexes up to 3.25 (Good). On the other hand, the fastest convergence time when interruption on the main link (VPN) is EIGRP with convergence time for about 15 seconds.

A Comparative Analysis of Unicast Routing Protocols for MPLS-VPN

MPLS-VPN technology is introduced to provide secure transmission with minimum propagation delay. This paper presents a comparative analysis of unicast routing protocols for MPLSVPN enabled networks. The motive behind this analysis is to observe the consequence of unicast routing protocols on the performance of MPLS-VPN enabled networks and to choose most suitable routing protocol for such type of networks. To conduct the analysis, a test bed is established in GNS3 simulator. Three main unicast routing protocols i.e. Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF) and Routing Information Protocol (RIP) has been considered in this work. Round-Trip-Time, Jitter and Administrative-distance are used as performance measure metrics. The experimental analysis indicates that EIGRP is the most suitable protocol among the aforementioned protocols for MPLS-VPN.

An enhancement of EAACK using P2P ACK and RSA public key cryptography

MANET – Mobile Adhoc Network is a self-configuring network that connected by the number of mobile nodes with wireless links and it has no fixed infrastructure. In this, each single node can operates as both a transmitter and receiver. It has been exploited in various applications such as disaster stuck areas, military, emergency revival etc. Nevertheless, the open intermediate and broad distribution of nodes in MANET can cause a vulnerable to different malicious attacks and MANET that can operate consistently even in the being there of inside packet drop attackers can be really challenging. Therefore, we need to develop Intrusion Detection System to detect the misbehavior nodes during the packet delivery with acknowledgement for the protection of MANET. In this paper, EAACK (Enhanced Adaptive Acknowledgment) is developed with Enhanced Interior Gateway Routing Protocol (EIGRP) hybrid protocol which consists of P2P ACK and RSA algorithm. At present, the network overhead is caused by the digital signature algorithm if more misbehavior nodes are presented on network. Hence, this proposed system is applied with EIGRP to reduce the network overhead caused by digital signatures in EAACK, and P2P (peer-peer) ACK and RSA (named after Ron Rivest, Adi Shamir and Len Adleman) provides more security to the network. S-ACK (Selective Acknowledgements) cannot differentiate the particular node is malicious node. Therefore, this proposed system introduces the P2P ACK to detect the misbehavior node efficiently. Here, RSA can encrypt the session key that creates the key more secure to improve the security level and P2P ACK use this encrypted key for the acknowledgement. In the P2P ACK, keys are generated by the RSA and distributed for signing and verifying the acknowledgement packets in advance. This proposed P2P ACK is used to enhance the detection of misbehavior nodes. The performance of this proposed method can improve the security level and reduce the routing overhead through the secured acknowledgement.

A validation model for non-lexical routing protocols

Routing protocols properties form an essential topic of research. Ensuring that a routing protocol is stable, loop free and reaches the global optimal topology solution is needed for both evaluating it and doing the required enhancements for it. There exist several trials in previous researches to enhance routing protocols. Those works depend on either theoretical models or simulation to validate their results. Existing validation models target lexical based routing metrics only.In this work, we propose a validation model for non-lexical routing metrics (such as Enhanced Interior Gateway Routing Protocol – EIGRP). Our validation model is based on abstract algebra. It helps in validating necessary routing properties and enhancing existing routing protocols in such a way that makes them meet those properties.

Performance Analysis of Route Redistribution among Diverse Dynamic Routing Protocols based on OPNET Simulation

Routing protocols are the fundamental block of selecting the optimal path from a source node to a destination node in internetwork. Due to emerge the large networks in business aspect thus; they operate diverse routing protocols in their infrastructure. In order to keep a large network connected; the implementation of the route redistribution is needed in network routers. This paper creates the four scenarios on the same network topology by using Optimized Network Engineering Tools Modeler (OPNET 14.5) simulator in order to analyze the performance of the route redistribution among three routing protocols by configuring three protocols from a set of Routing Information Protocol (RIPv2), Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), and Intermediate System to Intermediate System (IS-IS) dynamic routing protocols on each scenario. The first scenario is EIGRP_OSPF_ISIS, the second scenario is EIGRP_OSPF_RIPv2, the third scenario is RIPv2_EIGRP_ISIS, and the fourth scenario is RIPv2_OSPF_ISIS. The simulation results showed that the RIPv2_EIGRP_ISIS scenario outperforms the other scenarios in terms of network convergence time, the hops number, jitter, packet delay variation, packet end to end delay; therefore, it fits real time applications such as voice and video conferencing. In contrast, the EIGRP_OSPF_ISIS scenario has better results compared with other scenarios in terms of response time in case of using web browsing, database query, and Email services.

Due to the increase in the easy accessibility of computers and mobile phones alike, routing has become indispensable in deciding how computes communicate especially modern computer communication networks. This paper presents performance analysis between EIGRP and OSPFP for real time applications using Optimized Network Engineering Tool (OPNET). In order to evaluate OSPF and EIGRP’s performance, three network models were designed where 1st, 2nd and 3rd network models are configured respectively with OSPF, EIGRP and a combination of EIGRP and OSPF. Evaluation of the proposed routing protocols was performed based on quantitative metrics such as Convergence Time, Jitter, End-to-End delay, Throughput and Packet Loss through the simulated network models. The evaluation results showed that EIGRP protocol provides a better performance than OSPF routing protocol for real time applications. By examining the results (convergence times in particular), the results of simulating the various scenarios identified the routing protocol with the best performance for a large, realistic and scalable network.

Energy Aware Routing Protocol Poisson Process using Diffusion Update Algorithm in WSN

In wireless network communication, the energy efficiency is obtained from throughput of data transmission. During the network traffic and failure of data transmission, the energy efficiency and lifetime of network can be reduced in Wireless Sensor Networks (WSN). For this problem, we propose a duty cycling preservation scheme with Enhanced Interior Gateway Routing Protocol (EIGRP). EIGRP is used to preserve energy by reducing the network traffic in which the routing decisions are managed on network automatically. It reduces the workload on amount of data needs to be transferred, so the throughput is accomplished by EIGRP for WSN. The EIGRP based on diffused update algorithm to find the shortest path to goal of network. The duty cycling is commonly used for preserving energy effectively. In this process, the cluster heads play a major function in WSN. The aim of this paper is to extend a network lifetime and to preserve the energy by using EIGRP.

One of the computer network systems technologies that are growing rapidly at this time is internet. In building the networks, a routing mechanism is needed to integrate the entire computer with a high degree of flexibility. Routing is a major part in giving a performance to the network. With many existing routing protocols, network administrators need a reference comparison of the performance of each type of the routing protocol.

Research on New Routing Technology in WDM Network System

In this paper, a new routing design is presented. Interior gateway Protocols (IGPs), particularly Open Shortest Path First (OSPF), uses a simple single metric component, cost, which is based on the bandwidth of the link. Most large IP networks run Interior Gateway Protocols (IGPs) such as Open Shortest Path First (OSPF) or Intermediate System-Intermediate System (IS-IS) that select paths based on static link weights. Enhanced Interior Gateway Routing Protocol (EIGRP) is slightly more aware of the link characteristics in that it calculates a metric based on cumulative delay (delay is simply an arbitrary assigned value) and the minimum bandwidth value encountered between the source and destination. Routing technology can better the network operation efficiently.

VoIP Performance over Different Interior Gateway Protocols

Voice over IP technology integrates data and voice networks and offers flexibility by supplying device interoperability using standards-based protocols. Routing is an essential data networking function that provides an efficient real-time data delivery VoIP requires. Best-effort networks leverage Interior Gateway Protocol technologies to determine paths for routing packets between hosts. Architects for best-effort networks provide services by over-provisioning the links and routers so that network congestion does not introduce unwanted levels of latency, jitter, and packet loss. Route re-convergence can be detrimental to VoIP users in the middle of a conversation, as it impacts both latency and jitter. This paper studies how VoIP performance can be affected by different routing behaviors which include Routing Information Protocol, Open Shortest Path First and Enhanced Interior Gateway Routing Protocol. Network modeling and simulation have been carried out with OPNET Modeler to evaluate and compare performances.
