Efficient aggregation techniques, known as traffic grooming, allow higher bandwidth utilization and can reduce request blocking probability. These algorithms can also result in lower network cost in terms of electronic switching. In this paper we focus on traffic grooming in WDM mesh networks with dynamic traffic patterns. We offer two new grooming concepts called lightpath dropping and lightpath extension. These concepts are based on an alternative node architecture in which incoming optical signals can be dropped at a node, while optically continuing to the next node. Based on these concepts, we develop several grooming algorithms and study them under various network objectives. We also compare their performance with previously proposed lightpath-based grooming algorithms. Through extensive simulation results we show that our proposed approaches lead to lower request blocking probability and lower average number of logical hops when the number of transceivers per node is limited.","PeriodicalId":305639,"journal":{"name":"First International Conference on Broadband Networks","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125788679","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}

Murthy","doi":"10.1109/BROADNETS.2004.47","DOIUrl":"https://doi.org/10.1109/BROADNETS.2004.47","url":null,"abstract":"In this paper, we address the issue of providing multimedia traffic support in asynchronous ad hoc wireless networks. Since multimedia traffic has stringent bounds on end-to-end delay, we present a resource reservation for transmitting in such traffic. The existing asynchronous MAC protocols such as RTMAC (B.S. and C. Siva Ram Murthy, August 2002) and MACA/PR (C.R. Lin and M. Gerla, March 1999) when used for multimedia traffic provide inefficient utilization of network resources and affect call acceptance ratio and call drop ratio of multimedia traffic severely. Hence in this work, we modify the RTMAC protocol for supporting multimedia traffic so that it overcomes these limitations and improves packet delivery ratio and end-to-end delay of such traffic. The core concept of this protocol is a novel slot allocation strategy for efficient utilization of the available bandwidth for carrying multimedia traffic and best-effort traffic. Extensive simulations were performed to assess the performance of the protocol under varying network conditions. The simulations clearly indicate the gains in using such a slot allocation strategy for carrying multimedia traffic.","PeriodicalId":305639,"journal":{"name":"First International Conference on Broadband Networks","volume":"53 41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127949976","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}

At the edge of such a network, multi-service provisioning platforms (MSPPs) provide efficient data mapping enabled by generic framing procedure (GFP) and virtual concatenation (VC). The core of the network tends to be a meshed architecture equipped with multi-service switches (MSSs), In the context of these emerging technologies, we propose a load-balancing spare capacity reallocation approach to improve network utilization in the next-generation SONET metro networks. Using our approach, carriers can postpone network upgrades, resulting in increased revenue with reduced capital expenditures (CAPEX). For the first time, we consider the spare capacity reallocation problem from a capacity upgrade and network planning perspective. Our approach can operate in the context of shared-path protection (with backup multiplexing) because it reallocates spare capacity without disrupting working services. Unlike previous spare capacity reallocation approaches which aim at minimizing total spare capacity, our load-balancing approach minimizes the network load vector (NLV), which is a novel metric that reflects the network load distribution. Because NLV takes into consideration both uniform and non-uniform link capacity distribution, our approach can benefit both uniform and non-uniform networks. We develop a greedy load-balancing spare capacity reallocation (GLB-SCR) heuristic algorithm to implement this approach. Our experimental results show that GLB-SCR outperforms a previously proposed algorithm (SSR) in terms of established connection capacity and total network capacity in both uniform and non-uniform networks.","PeriodicalId":305639,"journal":{"name":"First International Conference on Broadband Networks","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124914980","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}
