KOL-Index: 8 While there are many algorithms for finding a node-protected pair of multicast trees in a graph, all of the existing algorithms suffer from two flaws: Firstly, existing algorithms either have a long running time or produce high-cost tree pairs (Time-Cost Trade-Off). Secondly, existing algorithms aim to produce a low-cost tree pair, but do not take delay constraints into account (Delay-Cost ...

KOL-Index: 4 Currently ISPs use tools, such as Interior Gateway Protocol Weight Optimizer (IGP-WO), to tune link weights of routing protocols so that offered traffic load is balanced evenly for network’s links. IGP-WO uses a sequential algorithm that prevents efficient use of parallel computing resources. We introduce a parallel link weight optimization architecture and compare its performance to IGP-WO. ...
