QoS negotiation between ISP and users is conducted by letting users specify their minimum and maximum transmission rate required. Each link tentatively allocates the maximum transmission rates to the traffics that are going to cross it. When the available capacity becomes not enough to satisfy the maximum transmission rate requirements of all on-going users, ISP reduces the allocated transmission rates of connections one by one according to their priorities. When the transmission rate allocated to every user decreases to the minimum transmission rate required, ISP then sends peak-time notification to all on-going users and employs pricing as an incentive mechanism to encourage voluntary disconnections (soft delay). Prices adopted during congestion is completely time-dependent and varies according to the real-time network congestion level. Specifically, the price of each time slot is obtained by solving a maximization problem of network utilization. If the available capacity is still not enough to satisfy the minimum transmission rate requirements of all on-going users, ISP forcibly delays connections one by one also on a priority basis (hard delay). Simulation results show that the proposed approach can significantly shift demand from peak time to off-peak time. When baseline demand is set to be 25% over the capacity of the link (i.e., peak time), 28.2% users voluntarily delay their connections for 0.23 hour under the price incentives, and only 0.84% users are forcibly delayed by ISP.","PeriodicalId":435905,"journal":{"name":"2014 International Conference and Workshop on the Network of the Future (NOF)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115841203","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}

Among the different models usually considered, the hexagonal network is the most popular. However, it requires extensive numerical computations. The Poisson network model, for which the base stations (BS) locations form a stochastic spatial Poisson process, allows to consider a non constant distance between base stations. Therefore, it characterizes more realistically operational networks. The Fluid network model, for which the interfering BS are replaced by a continuum of infinitesimal interferers, allows to establish closed-form formula for the SINR (Signal on Interference plus Noise Ratio). This model was validated by comparison with an hexagonal network. The two models establish very close results. In this paper, we show that the Fluid network model can also be used to analyze Poisson networks. Therefore, the evaluation of quality of service and performance becomes very easy, whatever the type of model, by using the analytical expression of the SINR established by considering the fluid model.","PeriodicalId":435905,"journal":{"name":"2014 International Conference and Workshop on the Network of the Future (NOF)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121037329","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}

Users geographically close to the server get better services due to low latency. A few existing scheduling algorithms can provide better strategies through efficient job scheduling and resource allocation techniques. However, these algorithms are not efficient enough for distanced clouds. In order to gain maximum profits with optimized scheduling algorithms, it is necessary to utilize resources efficiently and also prioritize the tasks that are near to the servers. This paper proposes job scheduling algorithms in a distributed datacenter (DC) network, where the algorithms assign user's workloads to Virtual Machines (VMs) hosted to DC close to the users to reduce response time. The aspect of the proposed algorithms is the use of delay to evaluate if a VM provide a low or a high delay, it is required that the location of the end user generating the tasks should be known. Our results show that prioritizing tasks for the nearest servers not only improve the quality of service (QoS) but also demonstrates better utilization of the resources.","PeriodicalId":435905,"journal":{"name":"2014 International Conference and Workshop on the Network of the Future (NOF)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127032026","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}
