Simplifying Manageability, Scalability and Host Mobility in Large-Scale Enterprise Networks using VEIL-click

The explosive growth in the network driven services and devices is causing existing networks to continually expand to accommodate the demands set by them. However, underlying network architecture can not sustain this continual expansion. As a result, several ad-hoc mechanisms are used as workarounds, which make the networks increasingly complicated and difficult to manage. In this paper, we present veil-click, which is aimed at simplifying the management of large-scale enterprise networks by requiring minimal manual configuration overheads. It makes it tremendously easy to plug-in a new routing-node or a host-device in the network without requiring any manual configuration. It builds on top of a highly scalable and robust routing substrate provided by VIRO, and supports many advanced features such as seamless mobility support, built-in multi-path routing and fastfailure re-routing in case of link/node failures. Our current prototype of veil-click is built using Click Modular Router framework, and is being deployed in our lab for the evaluation under the real traffic conditions. 1
