Cost-Effective Allocation Of Nested Routing Relay Node Resources

By implementing an overlay routing system, the ability to adjust various routing features (such as latency or TCP throughput) is available, without requiring any changes to the underlying standards. However, laying the groundwork for overlays involves setting up the overlay infrastructure. Here we have an optimization challenge that arises: The smallest set of overlay nodes to find is one that is sufficient to provide the necessary routing features. To prove that in a thorough manner, we analyze this optimization issue here. This paper shows that it is hard to approximate and so provides a nontrivial approximation approach. The details of the plan are examined in the context of numerous actual scenarios to measure the benefit that may be realized. Here, we examine a wide range of BGP-enabled routers to see how few required less than 100 BGP-enabled servers to implement BGP routing policy across the shortest pathways to all autonomous systems (ASs), hence lowering the average path length of routed pathways by 40%. The study is able to prove the scheme's many uses, the first of which is for TCP performance improvement, with results that achieve nearly optimal placement of overlay nodes. Also, when using Voice-over-IP (VoIP) applications, where a small number of overlay nodes can have a significant impact on maximum peer-to-peer delay, the study shows that the scheme's many functions are useful
