For such an environment involving so many heterogeneous resources, such as high-performance processors and optical links, faults seem to be inevitable. The faults will lead to the failure of the applications or highly delay the applications' finish times. Therefore, it is necessary to analyze resources' fault probability and then to better schedule the tasks of the application onto the appropriate resources so as to minimize the fault probability of the application. We address the task-scheduling problem based on the fault probability analysis for distributed computing applications over an optical network. We quantitatively analyze the fault probability of the processors and optical links in a given interval and propose a minimal fault probability (MFP) task-scheduling algorithm to minimize the fault probability of the application. We develop a simulator to evaluate the performance of the MFP algorithm. The simulation results prove the efficiency of the MFP algorithm.","PeriodicalId":49154,"journal":{"name":"Journal of Optical Networking","volume":"46 1","pages":"947-957"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1364/JON.7.000947","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66590958","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}

Maximum throughput traffic grooming in optical networks 光网络中的最大吞吐量流量疏导

{"title":"Maximum throughput traffic grooming in optical networks","authors":"Yong Wang, Q. Gu","doi":"10.1364/JON.7.000895","DOIUrl":"https://doi.org/10.1364/JON.7.000895","url":null,"abstract":"In synchronous optical networks (SONETs) and WDM networks, low-rate traffic demands are usually multiplexed to share a high-speed wavelength channel. The multiplexing-demultiplexing is known as traffic grooming and is performed by SONET add-drop multiplexers (SADM). The grooming factor, denoted by k, is the maximum number of low-rate traffic demands that can be multiplexed into one wavelength channel. SADMs are expensive, and thus an important optimization problem for traffic grooming is to maximize the number of accommodated traffic demands subject to a given number of SADMs. We focus on the unidirectional path-switched ring (UPSR) networks with unitary duplex traffic demands. We assume that each network node is equipped with a limited number L of SADMs, and our objective is to maximize the number of accommodated traffic demands in a given set. We prove the NP-hardness of this maximum throughput traffic grooming problem and propose a (k+1)-approximation algorithm. Extensive simulations are conducted to validate the performance of the algorithm. We also study the all-to-all traffic pattern for the maximum throughput traffic grooming problem and propose an algorithm that accommodates at least (nL⌊k⌋)/2 demands for a UPSR with n nodes. We also prove that any optimal solution can accommodate at most (nLk)/2 demands. Thus the solution of our algorithm is at most a constant factor (approximately 2) away from the optimum.","PeriodicalId":49154,"journal":{"name":"Journal of Optical Networking","volume":"7 1","pages":"895-904"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1364/JON.7.000895","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66590970","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}

Optical packet routers (OPRs) aim to provide a viable answer to these requirements by rendering the optical layer adaptable, reconfigurable at will, and cost-effective by means of statistical multiplexing of the network resources while satisfying end-to-end quality-of-service requirements. We study the role of OPRs in two different network approaches: an OPR adopting the legacy of a telecommunication solution and a solution pertinent to the role and the functionality of an IP world. To benchmark the two scenarios, a multilayer, multigranular OPR architecture is presented and its potential to cost-effectively scale toward petabit-per-second throughput is justified by means of physical layer performance and power consumption estimations for each case. Furthermore, the blocking and frame-loss performance of the proposed OPRs is presented, proving the viability of the proposed solutions.","PeriodicalId":49154,"journal":{"name":"Journal of Optical Networking","volume":"7 1","pages":"876-894"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1364/JON.7.000876","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66590329","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}
