OSPF Traffic Engineering using Legacy Equal Cost Multipath Load Balancing – running

This project focuses on Traffic Engineering (TE), which is an essential part of the operation and management of communication networks. We specifically examine a novel approach that uses only unmodified OSPF (Open Shortest Path First) shortest path routing with stock ECMP (Equal-Cost MultiPath) load-balancing. The main problem with OSPF ECMP is that it can only divide the traffic in equal proportion among the least-cost paths. Our proposal works around this limitation by setting up virtual links alongside existing physical ones, this way adjusting the effective splitting ratio. In this project, we study by simulation the performance of different versions of this approach.
