One elegant alternative to end-to-end service differentiation can be based on end point intelligence to control losses and delays when transferring data of individual Transmission Control Protocol streams. This paper describes a simple method to differentiate services based on congestion control parameter configuration of a TCP’s server, a priority marker, and that is still compatible to the mainly TCP implementations. A concept proof and results from simulation models are presented. We found out that our proposed approach also improves bandwidth share fairness among TCP’ individual flows of an aggregate.","PeriodicalId":397299,"journal":{"name":"Advanced Int'l Conference on Telecommunications and Int'l Conference on Internet and Web Applications and Services (AICT-ICIW'06)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129705676","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}

CWDM Fiber-wireless Employing a Supercontinuum Source 采用超连续源的CWDM光纤无线

Kartalopoulos","doi":"10.1109/AICT-ICIW.2006.72","DOIUrl":"https://doi.org/10.1109/AICT-ICIW.2006.72","url":null,"abstract":"To meet the current and future needs of the increasing bandwidth demand in wireless communications, base-to-base communication requires fast, reliable, secure and elastic bandwidth. One communication technology that meets these challenges is the fiber with wavelength division multiplexing. This technology multiplexes in a single fiber several wavelengths, each sourced by individual lasers thus adding to cost, complexity and fault management. An alternative, is a single laser source at higher power which when coupled onto a highly dispersive medium generates a wide spectral band known as supercontinuum. When this is appropriately sliced, multiple wavelength/channels are generated. In this paper, we develop a supercontinuum model, the spectrum of which is sliced The using FBGs to generate optical channels as recommended by ITU-T standards. We simulate our model at OC-48, selected for being popular in low cost applications. We also determine the longest link without amplification at performance objective 10-12 bit error rate.","PeriodicalId":397299,"journal":{"name":"Advanced Int'l Conference on Telecommunications and Int'l Conference on Internet and Web Applications and Services (AICT-ICIW'06)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116680763","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 Adaptive Grid Services (ASG) project develops a semantic Web service platform in order to fulfil the needs of Telematics, Telecommunications, eGovernment and Enterprise IT. Platform development is well under way, supporting semantic specification, registration, discovery, composition and enactment of composed and atomic services. Business in SWS delivery will be based on extensions of existing infrastructure, thus a roadmap for evolution is of crucial importance for business development. The roadmap covers the major items: standardisation, platform development, service scenario, and SWS business. Based on an example in the Telematics domain, this paper shows that prototype development is well under way, and tools are expected to reach the developer market within mid 2006. More crucial are domain ontologies, standardisation, and the service inclusion through existing platforms, expected to happen until 2008. Substantial market penetration will then follow.","PeriodicalId":397299,"journal":{"name":"Advanced Int'l Conference on Telecommunications and Int'l Conference on Internet and Web Applications and Services (AICT-ICIW'06)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117166405","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 algorithm to determine the mobile connected dominating set and the minimum number of CDS transitions is called OptCDSTrans and is based on a simple greedy approach: whenever a CDS is required, choose the CDS that will exist for the longest time. The above strategy is repeated over the duration of the network session. We prove that OptCDSTrans gives the optimal number of CDS transitions and simultaneously yields the stable mobile connected dominating set. We study the performance of OptCDSTrans in terms of number of CDS transitions and CDS size (the number of nodes constituting the CDS) for different conditions of node mobility and network density.","PeriodicalId":397299,"journal":{"name":"Advanced Int'l Conference on Telecommunications and Int'l Conference on Internet and Web Applications and Services (AICT-ICIW'06)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123573657","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}

SET claims that by using these cryptographic techniques it ensures the secrecy of the client’s credit card number, the integrity of transmitted data and the authentication of the involved entities. Our analysis shows that, under some considerations, none of these security properties would in fact be guaranteed. This paper describes the SET protocol and presents some interesting remarks about its security: some precautions must be taken when implementing SET, otherwise, it would result in an insecure protocol that would allow a dishonest person to harm both the client and the merchant.","PeriodicalId":397299,"journal":{"name":"Advanced Int'l Conference on Telecommunications and Int'l Conference on Internet and Web Applications and Services (AICT-ICIW'06)","volume":"21 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125551851","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}
