Recent measurement studies, however, found that there is generally a mismatch between traffic matrices and the actual network traffic. Since the link sizing and routing plans depend on the traffic matrix, this mismatch would result in inefficient use of the network resources. Traffic Engineering addresses this problem by utilizing alternate paths to distribute the traffic uniformly over the network. However, traffic engineering is applied at yearly or multi-year intervals, and may require re-routing of existing connections. In this paper, we introduce a route selection algorithm that operates during VPN set-up request arrivals to determine the best path for the incoming requests to achieve efficient use of the network resources. Our algorithm utilizes the concept of shadow prices and distributes the traffic uniformly across the network making better use of deployed network resources which in turn minimizes the network operator's overall infrastructure capital and operational expenses. The performance modeling results show that our solution outperforms shortest path and greedy routing algorithms. Furthermore, we show that an approximate lower bound, which may never be achieved by a feasible algorithm, is only 25% better in network cost compared to our solution.","PeriodicalId":230233,"journal":{"name":"2009 IEEE Sarnoff Symposium","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133977497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Recursive Fair Stochastic Matrix Decomposition (RFSMD) algorithm is used to determine near-optimal transmission schedules for each switch, where the jitter and service lead/lag of all flows are simultaneously bounded by K · IIDT time-slots for small constant K, where IIDT denotes the Ideal Inter-Departure Time for each flow. It is established that: (a) the number of buffered cells per flow per switch is near-minimal and bounded by O(K) cells, (b) the end-to-end queueing delay along an H-hop path is near-minimal and bounded by O(KH · IIDT ) time-slots, (c) the end-to-end jitter and service lead/lag are near-minimal and bounded byO(K · IIDT ) time-slots (the jitter is not cumulative), and (d) all network-introduced jitter can be provably removed using small playback buffers with O(K) cells. It follows that all statically-provisioned traffic flows, including VOIP, IPTV and Video-on-Demand traffic, can be delivered with essentially-perfect QoS even at 100% loads, thereby achieving the optimal statistical multiplexing gain. The bounds also apply when the crossbar switches use a combination of IQs and crosspoint queues. These theories explain several exhaustive results which have recently been presented in the literature.","PeriodicalId":230233,"journal":{"name":"2009 IEEE Sarnoff Symposium","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115990855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
