The undertaking of this paper is twofold: This paper's first-of-its-kind examination of the problems of logical link mapping and traffic flow routing unveils that backhaul traffic, a flow loop that occurs at any lower link layer below the traffic layer except its own, could happen in the traffic flow routing even when no backhaul occurs in the link mapping, prompting our discussion on the investigation of crosslayer survivable link mapping when traffic layers are explicitly considered and survivability is required. In addition to the theoretical treatment on the connection among and between link and traffic layers, a forbidden link matrix is also identified masking part of the network for use in situations where some physical links are reserved exclusively for a designated service, mainly for the context of providing multiple levels of differentiation on the network use. The masking effect is then evaluated on two metrics using two practical approaches in a sample real-world network, showing that both efficiency and practicality can be achieved.","PeriodicalId":202408,"journal":{"name":"2010 14th International Telecommunications Network Strategy and Planning Symposium (NETWORKS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121976437","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}

We have measured and analyzed the peer distribution in BitTorrent, which is one of peer-assisted content delivery networks (CDNs). From the peer distribution, we show the potential of the high-cost transit traffic reduction. We then propose a peer selection preference which takes into account the economical relationships among Autonomous Systems (ASes) in peer-assisted CDNs to reduce the high-cost transit traffic. Since most commercial Internet service providers cannot disclose the relationships due to their commercial contract, we employ degree-based heuristics for inferring the relationships; degree can be approximated from publicly available BGP routing tables. We show that the peer selection method utilizing the proposed preference can reduce interdomain transit traffic exchanged with provider ASes by trace-driven computer simulation. The significance of this paper are 1) we show the potential of the transit traffic reduction from peer distribution analysis, and 2) the peer selection method with the proposed preference appropriately reduces the high-cost transit traffic with degree-based AS relationships inference heuristics even though there is no public AS relationships information.","PeriodicalId":202408,"journal":{"name":"2010 14th International Telecommunications Network Strategy and Planning Symposium (NETWORKS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115183533","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 addition, the tool was designed to have a flexible upgradability, i.e. no changes of the system programs are required when adding the new functions. The system functions are to design lightpaths and wavelengths allocated to ROADMs for the lightpaths required to groom given traffic. The tool also can search possible lightpath routes made by ROADMs with specified switch states, and output the total optical losses of the routes. By the tool implemented in one management and 3 calculation machines for the parallel processing, the total time to obtain the results for a 5-node IP-over-CWDM network was reduced down to 65 % of the total time by the tool with a single machine without parallel processing. The tool enables the network administrators to design and manage the lightpath reconfigurations effectively without errors by avoiding making unlinked lightpaths through routes with higher losses to connect nodes, before the reconfiguration.","PeriodicalId":202408,"journal":{"name":"2010 14th International Telecommunications Network Strategy and Planning Symposium (NETWORKS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114174202","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 IMS as control layer must perform end-to-end services with a guarantee to secure and manage anomalies due to the network diversity, however the network performance is dynamic and the amount of useful information is limited so it's difficult to detect problems after supply before they surface. The IMS to fulfill service monitoring must use the eTOM (enhanced Telecom Operations Map) Framework, That tool can simplify integration, supervision and monitoring over a new telecommunications network. IMS have to provide a guaranteed Quality of Service (QoS) to the users in the case of VoD service, the providing procedure respect QoS standards and enter into fulfillment processes although remains assurance and billing, for that we propose a monitoring system-based eTOM that retrieve supply information in real-time and simulate the business operation with distributed WSOA concept. Furthermore, set of information retrieved will be used in SLA (Service Level Agreement) verification, take corrective actions, and predicate service-level impact.","PeriodicalId":202408,"journal":{"name":"2010 14th International Telecommunications Network Strategy and Planning Symposium (NETWORKS)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123486428","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}
