Software Resolved Networks: Rethinking Enterprise Networks with IPv6 Segment Routing

Wed, 02/28/2018 - 21:54 by Mathieu Jadin


Enterprise networks often need to implement complex policies that match business objectives. They will embrace IPv6 like ISP networks in the coming years. Among the benefits of IPv6, the recently proposed IPv6 Segment Routing (SRv6) architecture supports richer policies in a clean manner. This matches very well the requirements of enterprise networks.

In this paper, we propose Software Resolved Networks (SRNs), a new architecture for IPv6 enterprise networks. We apply the fundamental principles of Software Defined Networks, i.e., the ability to control the operation of the network through software, but in a different manner that also involves the endhosts. We leverage SRv6 to enforce and control network paths according to the network policies. Those paths are computed by a centralized controller that interacts with the endhosts through the DNS protocol. We implement a Software Resolved Network on Linux endhosts, routers and controllers. Through benchmarks and simulations, we analyze the performance of those SRNs, and demonstrate that they meet the expectations of enterprise networks.
