Towards Coordinated Interdomain Traffic Engineering {

interdomain traffic engineering is difficult, ad hoc techniques are unfortunately the state-of-the-art today?

Efficient and Robust Routing of HighlyVariable Traffic

Use certain tunnels to split single hop inter connection between routers to two hop routes.

Traffic is split over all possible two-hop routes

Load is balanced and the network is more robust?

But the overall requirement of network capacity maybe double.

The comercial demand for convergence of circuit based network and IP based network is high. And a lot of problems need to be solved:

Network-Wide Decision Making: Toward AWafer-Thin Control Plane {

What is an IP control plane?

Centralized computation vs. distributed scheme

a mixed plan?

two-phase commit?

Resilient IP control plane: Path to network convergence {

IP/MPLS backbone : what is MPLS? http://www.edu.cn/20010829/209669.shtml

The Internet control plane always adapts to the demands placed on it—and there’s no reason to think it is incapable of evolving to support the requirements of converged services. Several emerging technologies address the need for a more reliable, scalable, and resilient IP control plane.

In short, the convergence of voice and data services onto a single network is already well underway. In the current climate, service providers must evolve their networks to remain competitive. Before voice and data services can migrate to a single IP/MPLS core, the IP control plane must evolve to support the scalability, reliability, and stability required by business services. Fortunately, technologies exist today that enable these advances. Routing technologies such as stateful protocol protection, optimized route convergence, and high-performance scalable routing processors can provide the IP control plane with the resiliency that’s needed.
