Research ArticleOpen accessIn the abstractEnhanced Variable Splitting Ratio Algorithm for Effective Load Balancing in MPLS NetworksG. Murugesan, A. M. Natarajan, C. VenkateshFast load balancing is of the highest importance to utilize the resources effectively and improve the performance of the Multi Protocol Label Switching (MPLS) enabled Internet Protocol (IP) networks. Load balancing splits a part of traffic called splitting ratio from the maximum loaded path in to minimum loaded path. One very strong constrain in balancing the load is the tradeoff … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 7,340 accessesView PDFCite
