- A Constrained Multipath Traffic Engineering Scheme for MPLS Networks
- A traffic engineering problem consists of setting up paths between the edge nodes of the network to meet traffic demands while optimizing the network performance. It is known that total traffic throughput in a network, hence the resource utilization, can be maximized if the traffic demand is split over multiple...

- Link-State Routing With Hop-by-Hop Forwarding Can Achieve Optimal Traffic Engineering
- Link-state routing with hop-by-hop forwarding is widely used in the Internet today. The current versions of these protocols, like OSPF, split traffic evenly over shortest paths based on link weights. However, optimizing the link weights for OSPF to the offered traffic is an NP-hard problem, and even the best setting...

- A Scalable Heuristic for Hybrid IGP/MPLS Traffic Engineering - Case Study on an Operational Network
- In current IP networks, a classical way to achieve traffic engineering is to optimise the link metrics. This operation cannot be done too often and can affect the route of a lot of traffic. Multiprotocol Label Switching MPLS opens new possibilities to address the limitations of IP systems concerning traffic...

- Interface Split Routing for Finer-Grained Traffic Engineering
- Legacy IP routing restricts the efficacy of traffic engineering solutions. This restriction stems from the constraint that traffic at a node must be uniformly split across all next-hop nodes corresponding to equal cost shortest paths to a destination. Proposals that alleviate this constraint either completely overhaul legacy IP routing, or...
