Literature papers typically design chunk scheduling algorithms by considering the chunk delivery ratio as performance metric. We propose a push-based algorithm, which not only tries to maximize the chunk delivery ratio but it also takes into account and tries to minimize the delivery delay of chunks at the peer nodes. This is an important requirement, when dealing with realtime multimedia flows. Another important contribution of this paper is the design and implementation of a simulator able to evaluate the performance of large scale P2P networks (tens of thousands peers). The importance of this contribution lies in the fact that existing simulators and performance studies handle at most hundreds or few thousands of peers, while real-life P2P streaming systems aim at distributing contents to several hundreds of thousands, if not millions, of users. The performance evaluation study aims at providing a comprehensive view of what performance can be expected for mesh-based peer-to-peer streaming systems, both in terms of chunk delivery ratio and delay, for a large range of the number of users. The individual effect of a variety of system parameters, and especially number of partner nodes in the mesh, constrained link bandwidth, node heterogeneity, and network size, has been analyzed. Our results show that performances of the proposed push-based solution are already quite effective even with severely bandwidth constrained large scale networks.","PeriodicalId":255580,"journal":{"name":"2008 4th International Telecommunication Networking Workshop on QoS in Multiservice IP Networks","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114259152","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}

Indeed, the independent optimisation of a diverse set of objectives using layer-local information can lead to operational instability and sub-optimal resource usage. We argue that an explicit interaction between the application and network layers can provide benefits for each layer. We postulate that such cross-layer interaction must however fulfil two conditions to be pragmatic and acceptable: 1) no explicit information about the structure and operations of each layer must be ex-changed; 2) each layer must be able to independently set its own policies and objectives. Because we limit this interaction to application hosts and their access ISP, the proposed method is also incrementally deployable. We show, through evaluation of simple examples, that explicit cross-layer interaction does indeed bring performance benefits to all parties, for applications ranging from simple client-server to more complex overlay network scenarios.","PeriodicalId":255580,"journal":{"name":"2008 4th International Telecommunication Networking Workshop on QoS in Multiservice IP Networks","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125633961","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}

One of the main criticalities of the system is the very large size of the contents to be transferred while respecting the maximum download time requirements. From the operator perspective, this criticality translates into the objective of optimizing the usage of network resources while complying with QoS constraints. The goal of this paper is first to present the network architecture and procedures relevant to the distribution service, and to specifically analyse the problem of service request routing (4-7 routing), whose objective is to select a set of servers to satisfy a content request efficiently. In particular, we focus on the definition of the mathematical model of the problem of minimising the network operational cost of the content distribution. Since some known professional, optimisation tools are not able to find the global optimum even in very simple configurations, we propose a heuristic approach based on the min-plus convolution. Preliminary numerical results show that such an algorithm outperforms the selected professional tools, while maintaining an affordable computation time.","PeriodicalId":255580,"journal":{"name":"2008 4th International Telecommunication Networking Workshop on QoS in Multiservice IP Networks","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127968591","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}
