TITLE: A COLLATION OF ROUTING TECHNOLOGIES THAT INVESTIGATES FLEXIBILITY, STABILITY AND SECURITY OF AN ISP.

CLIENT: DAVID EVANS (UNIVERSITY OF SUNDERLAND)

DATE: 22ND JANUARY, 2016

EXECUTIVE SUMMARY

Not Flexible to the routing demands. Immediate and Expansion plans will Incurring

more cost as customers must ensure that the Customer Edge Routers (CE) meet the BGP requirement of the ISP as well as their internal routing protocols (OSPF) & (EIGRP).

Difficult to Maintain (2) Different Routing Protocols

Simplicity in configuration

Prevents of routing information loop

Offers reliable updates using Transmission Control Protocol (TCP).

PROBLEM STATEMENT

An ISP enterprise is faced with the challenge of satisfying the customers demand

by providing a flexible mechanism where the customer can interconnect with

their other site branches, using their choice of routing protocol mechanism

through the ISP network. The ISP enterprise also demands that the solution that

will be deployed should possess scalability, security and stability to protect the

image and integrity of the company.

CLIENT REQUIREMENTS

Design a reliable, flexible and stable ISP network Demonstrate how recent routing technologies can be deployed by

ISPs to ascertain customer’s routing flexibility. Present a practical solution which ensures that the above network

design is stable and scalable. Offer a solution that demonstrates how recent security techniques

are deployed in the ISP network design. Recommendations that provides support on how the practical

deliverables can be deployed.

PROJECT OBJECTIVES

1. Present a critical research analysis, by utilizing recent and reputable journals that covers the design and implementation of a flexible, stable and secured ISP network.

2. Produce a design for a flexible, stable and secured ISP network.

3. To produce a practical lab prototype solution that satisfies the client requirements

4. Demonstrate how the ISP inter-domain routing protocols alongside some deployed IGPSs are engineered to publish customer’s VPN routers that channel packets.

5. Offer a written (report) that elaborates how the practical solution (ISP network prototype) can be flexible to customer routing demands in a scalable and stable and secured manner.

6. Produce a well analyzed and structured dissertation to accomplish all the goals of the project.

7. Offer recommendations for future researches within this project subject area.

RELEVANCE OF THE RESEARCH CARRIED OUT Recent academic papers has been critically analyzed within the literature review which has provided Advanced knowledge regarding the following:-

The components that make up an ISP network [Layout of the Interior Gateway Protocol (IGP), Network Layout, Methodology of Network Addressing, Customer Connectivity as well as Peering and Transit Connections]

Current ISP routing technologies used [ MPLS-VPN, L3VPN (VPNv4), BGP and IGPs] Recent ISP stability techniques [Link Redundancy, Route Reflectors, Hub and Spoke] Security techniques deployed within an ISP network [MPLS & IPSec]

These knowledge has been used as the major tool to designed and implement the ISP prototype solution for the client.

PROJECT METHODOLOGY

ARCHITECTURE OF THE ISP PROTOTYPE NETWORK

NETWORK DIAGRAM OF THE ISP PROTOTYPE

ISP PROTOTYPE IMPLEMENTATION New Cisco software application called Virtual Internet Routing Lab (VIRL) Necessary configurations has been deployed on all the routers Evidence that shows the functionality of the ISP prototype are seen in the numerous

snapshots provided within the appendices of the dissertation. WireShark Application has also been used with VIRL to capture Traffics across the ISP

network.

PERFORMANCE TEST RESULTS FOR THE ISP PROTOTYPE

Flexibility of Routing Technologies on CUST-1 has been Successful

Flexibility of Routing Technologies on CUST-2 has been Successful

PERFORMANCE TEST RESULTS FOR THE ISP PROTOTYPE

Flexibility of Routing Technologies on CUST-3 has been Successful

PERFORMANCE TEST RESULTS FOR THE ISP PROTOTYPE

Security Using MPLS and IPSec has been Successful IPsec Extra Security

Multi-protocol Label Switching (MPLS)

Security

PERFORMANCE TEST RESULTS FOR THE ISP PROTOTYPE

RECOMMENDATIONS

The PEs within the ISP will have to be a multivendor equipment to support all the possible customer routing demands. (This will incur a lot of cost).

Networking experts in different routing technologies will be required within the ISP enterprise, to troubleshoot and maintain different routing technologies. This also incurs cost.

RIP should not be used as a choice of CE-PE inter-domain routing protocol as it has a limitation of (15-hops).

The ISP administrative should be remotely in charge of configuration and maintenance of the CE routers, to enable smooth Network troubleshooting and manageability.

PROJECT EVALUATION

All Project Objectives and Client Requirements were achieved.

A Proposed MPLS-VPN /MP-IBGP/ L3VPN/IPSEC approach has shown to be effective but reveals the complexity of using different routing protocols (IGPS) between (CE-PE).

A Set Of Recommendations Identifying Best Practices In deploying this solution has been provided.

A Report and Copy of the ISP Prototype Solution has been Delivered To Client.

CONTRIBUTION OF THIS PROJECT

This research fills the knowledge gap of the network routing operations within an ISP, by providing advance knowledge on ISP routing mechanisms, stability and security techniques.

Offers the Client with a useful solution that provides flexibility to the routing demands of customers, in a stable and secured manner.

Offer ISP enterprises the tool to be as step ahead of counter-competitors, keeping old and new customers happy.

Boost the financial profitability of ISP enterprises. ISP Customers would not need to invest in expensive networking equipment Offer ideas to networking researchers

CLIENT FEEDBACK

The student has produced a very useful simulation that I will use to investigate IGP interactions with

L3VPNs.

Good Work! Could have Examined some of the technical issues of (PE-CP) IGP interactions in more depth.

CONCLUSION

This Research Offers a standard literature and practical prototype that addresses the ISP problem of connecting the dispersed branch sites of customers, by using their preferred routing protocols (IGPs); instead of the usual

(BGP) on the (CE-PE) link, in a secured and stable manner.

Using this solution, ISPs can afford to put Simultaneously the

“People and Profit” successfully.
