IPv6 stack and BGP

Abstract [en]

IPv6 is a new version of IP which is designed to be an evolutionary step from IPv4. IPv6 has an enormous address space. It also has optional security and other optional features built into the protocol. IPv6 will, in the future, be used in the 3G mobile networks, as well as in the Internet. To meet the future demands on IPv6 in Internet routers, Ericsson wants to extend the IP stack in their multi-service switch AXD301 so that it supports IPv6 as well as IPv4. The work has been divided into two parts. One theoretical part and one practical part. The theoretical part specifies a way for an IPv4 network to interface one or more IPv6 networks. Both the case of interdomain and intra-domain routing is considered. This is achieved using a modified version of the Border Gateway Protocol (BGP), and a Transport Relay Translator (TRT). BGP is used to carry inter-domain routing information, and has been modified so that it can carry routing information for multiple Network Layer protocols (in this case IPv6) over IPv4. TRT is used for the case when a host in an IPv6 network want’s to talk to a host in an IPv4 network and vice versa. AXD301 is using an IP-stack in a regular UNIX application. The source code also contains code to support IPv6. The IPv6 code is not currently part of the AXD IP stack. The IP stack can execute and be tested on a regular SUN workstation. The practical part was to include the IPv6 code in the AXD301 IPstack, test it on a SUN workstation and to add IPv6 support in the AXD IP trace utility. The IP trace utility is a program for tracing traffic from and to the stack. Tests shows that the implementation of the IPv6 stack works, the IP trace utility can trace basic IPv6 traffic and the IP statistics utility can show IPv6 statistics.
