[en] IPv6 is the latest Internet Protocol which is seeing a growing deployment, and is expected to replace IPv4. One of the differences of IPv6 with IPv4 is the much larger address space, with IPv6 having 2^96 times more addresses than IPv4. This means there are more than enough addresses available for all the devices on the internet, which allows us to eliminate NAT and provide more transparent end-to-end connectivity. It also makes it very affordable for an end host to have multiple addresses, and indeed the IPv6 specification allows a host to have multiple addresses from different prefixes on the same interface.

This thesis will describe some possible uses of having multiple prefixes in a network interface, but it will focus mostly on the problems that appear when trying to integrate these changes into today's networks. One such problem is related to multihoming, and we will explain how it can be solved by using new methods of forwarding and routing which we call in this thesis Source Address Dependent Routing (SADR).

Based on specifications and guidelines of the IETF, we provide an implementation of SADR in simulated routers, and we extend the OSPFv3 routing protocol to support SADR. With our new implementation, we performed some scalability tests to learn more about the changes that SADR causes in network traffic.

The results show that the implementation of SADR doesn't have a large impact on the amount of traffic in the network.
