For the purpose of dynamical bandwidth provisioning, we need a model that can capture online the traffic characteristics and facilitate mathematical analysis. A mixture of gamma distributions can approximate any distribution with nonnegative support as closely as desired. It can not only characterize field data well, but also facilitate analytically tractable results far performance evaluation. This paper uses a Gamma mixture to model Internet traffic and proposes an online algorithm to fit the model to actual Internet traffic. The fitted model is applied to provision bandwidth dynamically, and many simulation and experimental results are also provided","PeriodicalId":425107,"journal":{"name":"4th Annual Communication Networks and Services Research Conference (CNSR'06)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128668961","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}

In this paper, we present detailed features for transparent ring-to-ring interconnection in optical domain by using planar lightwave circuit (PLC)-based ROADMs. The proposed ring-to-ring interconnection features will alleviate the use of costly optical-electrical-optical (O-E-O) regenerators and optical cross connects (OXCs) from the network. In order to characterize the PLC-based ROADM's performance in metro network environment, a testbed is designed and reported in this paper. In conjunction with the testbed, simulation models have been developed. Detailed test results obtained both from experiment and simulations demonstrate that our developed simulation models can be used for analyzing scenarios for next generation's metro optical network","PeriodicalId":425107,"journal":{"name":"4th Annual Communication Networks and Services Research Conference (CNSR'06)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121374183","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}
