In a previous paper [1] we considered WDM passive optical interconnection architectures that exploited a broadcast-and-select approach and wavelength agility at linecards to implement the required switching functionality. A non-trivial modeling of the used optical components, based upon the characteristics of commercially available devices, showed that aggregate capacities in the order of few Terabits are possible in very simple single-plane optical switching fabrics. This paper extends the approach toward multiplane, single-hop, optical interconnection architectures, which add the space dimension to the wavelength one for multiplexing packets to be transfered from input to output linecards. Our scalability analysis shows that the multiplane approach does not gain much in terms of aggregate capacity due to the need for space switches (realized with Semiconductor Optical Amplifiers - SOAs), but, as expected, reduces significantly the wavelength agility requirements of tunable devices, making the overall design more feasible.","PeriodicalId":155835,"journal":{"name":"2008 International Conference on Optical Network Design and Modeling","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126551282","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}

The issue of how to synthesize a realistic self-similar traffic pattern for OPS networks is discussed. As a result, a methodology for designing self-similar batch sources suitable for OPS networks is proposed. Then, a buffering dimensioning study of the switching fabric is conducted under the proposed traffic model. Also, the variation in the self-similar traffic parameters suffered in the output process of the switch is evaluated and discussed.","PeriodicalId":155835,"journal":{"name":"2008 International Conference on Optical Network Design and Modeling","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126573282","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}

This service can consume a large amount of network bandwidth, due to the large volume of transmitted data and to the number of receivers, thus multicast transmission proves to be very useful. Consequently, a key issue of the system is the request routing algorithm, the goal of which is to optimise the QoS-guaranteed delivery of live streams in the backbone, each one towards a set of theatres. We consider the Multi Protocol Label Switching, which has emerged as an elegant solution to meet traffic engineering and resource reservation requirements, and focus on the overall request routing procedure, the mathematical modelling of the problem, and relevant solving algorithms. We present the comparative performance evaluation of these algorithms by means of an extensive simulation campaign performed with the OMNET++ simulation platform.","PeriodicalId":155835,"journal":{"name":"2008 International Conference on Optical Network Design and Modeling","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124905994","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}

The processing time of the BCP is variable, and depends on the number of available gaps over which to perform the search. This work analyses the gap distribution in such reservation table, and derives an expression for the waiting time of BCPs, assuming LAUC-VF scheduling. Our findings can be applied to the dimensioning of the offset time values in OBS networks, for a realistic case of BCP variable processing times.","PeriodicalId":155835,"journal":{"name":"2008 International Conference on Optical Network Design and Modeling","volume":"336 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134130241","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}

Modern backbone networks use a mesh of fiber optic cables, which are, due to their ubiquitous deployment, prone to failures. The goal of this paper is to develop efficient computational methods for assessing the availability of such networks. We present both analytical and simulation approaches for this problem. Our analytical approach is based on cut set enumeration, while our simulation approach is based on Monte Carlo sampling techniques. To facilitate the computational process, we employ artificial intelligence methods based on genetic algorithms. We consider the expected loss of traffic (ELT) as the availability measure and show that ELT can be accurately estimated through an efficient procedure.","PeriodicalId":155835,"journal":{"name":"2008 International Conference on Optical Network Design and Modeling","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131749102","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}
