Abstract

Objectives: IPv6 is to be used largely in the growing internetworks. At present IPv4 is used extensively. Migrating from IPv4 to IPv6 is a challenge, considering many factors like hardware, applications and networks reach ability. This paper explains the drawbacks of IPv4, advantages of IPv6 and migration techniques to IPv6.

Methods/Analysis: GNS3 is a networking simulator. Using this simulation tools, network topologies can be built, and the routers can be configured. Using this GNS3 simulation tool, two topologies are built with IPv4 and IPv6 to coexist, and only IPv4 networks between two IPv6 networks.

Results/Findings: The appropriate migration techniques, dual stack and tunneling were configured in the routers and end results of reach ability were tested.

Applications: IPv6 can be used in many applications like IoT, vehicle tracking, automatic maintenance of building, in health care, remote monitoring, etc.

Abstract

Objectives: Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) Carrier Supporting Carrier (CSC) enables one MPLS VPN-based service provider to allow other service providers to use a segment of its backbone network. Carrier supporting carrier (CSC) is implemented in circumstances in which one service provider needs to use the transport services provided by another service provider. The service provider providing the transport is called the backbone carrier and the service provider using the services provided by the backbone carrier is called a customer carrier. The customer carrier can either be an ISP provider or an MPLS VPN service provider. In my study, I have taken the case of the carrier customer is a service provider running MPLS VPN.

Methods/Analysis: In this project, we are giving interconnection between customer branches of ISP1. The POP locations of ISP1 are running with MPLS and ISP1 POP locations are interconnected via other ISP Backbone carrier ISP2 using MPLS network. Customers connected in POP sites 1 and POP sites 2 to ISP1, are using BGP protocol to send the network information to ISP1 in their respective location. ISP1 is also running BGP, collecting the information of Customers from both the POP sites using BGP protocol and sharing this information from POP1 site to POP2 site via backbone carrier ISP2.

Application: Backbone carrier ISP2 creates an MPLS link with both POP sites of ISP1 and carries customer network information via ISP2 network such that both the customer branches can share data across POP locations.

Results: The above network was simulated using GNS3 network simulation tools and the reach ability between the two customer sites of ISP2 the customer carrier was tested, with success.
