Several new results on flow configuration, pricing and routing are presented in addition to overviews of relevant previous works. These derived by making use of the concepts Nash equilibrium, Pareto optimality and Stackelberg strategies borrowed from game theory. These are highlighted by means of illustrative examples. It is claimed the control-theoretic view on incentives in the theory of non-cooperative games provides for tools to solve various control and management problems in high-speed communication networks hence many QoS problems too.","PeriodicalId":422115,"journal":{"name":"TELSIKS 2005 - 2005 uth International Conference on Telecommunication in ModernSatellite, Cable and Broadcasting Services","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115615574","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 this procedure, a wavelength continuous route for a new lightpath that needs to be established is created by assigning new wavelengths to few existing lightpaths while retaining their routes. The benefits of wavelength rerouting technique are researched in this paper. For this purpose, we developed the software for wavelength rerouting simulation. A simulation is performed and illustrated for an optical WDM network with nine nodes and mesh topology. Results show that network performances in terms of lightpath blockings could be improved when using rerouting technique.","PeriodicalId":422115,"journal":{"name":"TELSIKS 2005 - 2005 uth International Conference on Telecommunication in ModernSatellite, Cable and Broadcasting Services","volume":"198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121322564","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 propose using of this scheduling system for arbitration at inputs and crosspoints. If the virtual output queue (crosspoint buffer) becomes empty, the input (crosspoint) arbiter updates its pointer to the next location in a fixed order. Otherwise, the pointer remains at the current virtual output queue (crosspoint buffer). To avoid unfairness under some extremely unbalanced traffic pattern limited service matching is presented. It is shown that this new solution offers high performance for several admissible traffic patterns using only one-cell crosspoint buffers.","PeriodicalId":422115,"journal":{"name":"TELSIKS 2005 - 2005 uth International Conference on Telecommunication in ModernSatellite, Cable and Broadcasting Services","volume":"45 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116010375","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}

While the digital subsystems of the nodes are still following Moore's Law, there is no such trend regarding the performance of analog components. This work proposes a fully integrated architecture of both digital and analog components (including local oscillator) that offers significant reduction in cost, size and power consumption of the overall node. While such a radical architecture cannot offer the reliable tuning of standard designs, it is shown that by using randomized signal processing techniques, a dense network of such nodes can achieve throughput linear in the number of channels available for communication. Moreover, the ratio of the achievable throughput of the untuned network to the throughput of a tuned network with perfect coordination is shown to be close to 1/e.","PeriodicalId":422115,"journal":{"name":"TELSIKS 2005 - 2005 uth International Conference on Telecommunication in ModernSatellite, Cable and Broadcasting Services","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122725777","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}

Antennas are fed by two ideal voltage generators of voltages U/sub 1/ and U/sub 2/.

The SIE-H was solved in the so-called symmetrical and asymmetrical working regimes, and afterwards, self- and mutual- admittances/impedances were determined.
