However their Quality of Service (QoS) is strongly influenced also by resilience. This paper focuses on the important problem of server selection with the highest two-terminal availability for distributed multimedia services. An analytical model gives optimal global server selection in terms of the highest two-terminal reliability for client-server connection in simple networks. For more complex networks a heuristic algorithm is utilized. The proposed algorithm allows to obtain better reliability values than the common shortest path server selection scheme.","PeriodicalId":230802,"journal":{"name":"2008 10th Anniversary International Conference on Transparent Optical Networks","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123972208","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 estimated pore diameter is 40 - 70 nm. The PS film is installed into a planar glass cell and infiltrated with a nematic liquid crystal (LC) mixture E7. The resonant wavelength of the structure is continuously tuned using thermal dependence of the LC effective refractive index. The reversible tuning of the resonance in the range of 13 nm is demonstrated. Spectra of the structure with the LC in the nematic phase were simulated using the Frank free energy approach with an assumption of the LC molecular configuration being escaped radial (ER). These spectra are very close to corresponding experimental data. Thus, the ER model for nematics in pores narrower then 100 nm is still applicable.","PeriodicalId":230802,"journal":{"name":"2008 10th Anniversary International Conference on Transparent Optical Networks","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124438939","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 architecture, burst assembly algorithms have an important influence in the pattern traffic that characteristic this sort of optical networks. On the other hand, traffic coming from new applications (such as video on demand, Voice over IP, online gaming or Grid computing) that have real time and bandwidth constraints, has been experimented a rapid increment. Consequently, we consider important to evaluate the performance of traffic from real time applications over OBS networks. In this paper, we evaluate the effects of implementing a size-based burst assembly scheme at the edge node, on the performance of video transmissions (MPEG4/RTP/UDP) over an OBS network. Through event driven simulation, we conclude about the optimal configuration values for the assembly algorithm in order to guarantee high quality video transmissions. With this purpose, we analyse the PSNR, the delay problem and the data loss due to the relation between the amount of traffic source and the maximum burst size.","PeriodicalId":230802,"journal":{"name":"2008 10th Anniversary International Conference on Transparent Optical Networks","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127761006","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 such systems, the information is transmitted optically on different wavelengths but it is transferred across the network through fibre links that are terminated by SONET/SDH equipment. In such networks, layer crossing is inevitable, requiring deep data inspection and complex protocol processing, resulting in limited scalability and high installation, operation and maintenance cost. It is however the only reliable end-to-end service delivery scenario available today that utilises the optical bandwidth and guarantees provisioning of resources. In this paper we review the alternative concept of CANON (clustered architecture for nodes in optical networks), a scenario that utilises clustering of nodes in ring topologies to create a hierarchy in transporting traffic in a dynamic, future proof and scalable manner. Here we emphasize on the optical crossconnect architectures that can serve such a network scenario.","PeriodicalId":230802,"journal":{"name":"2008 10th Anniversary International Conference on Transparent Optical Networks","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116333897","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}

To this end PON networks are regarded as one of the most prominent alternatives. This paper proposes a novel MAC scheduling algorithm for GPON networks that can offer efficient operation, combining QoS differentiation with high network utilization. It achieves improved performance by making use of both fixed and dynamic bandwidth allocations along with predictive allocations and the novel concept of offset-based scheduling with flexible intervals, being thus able to effectively adapt to fluctuations of traffic and meet quality of service requirements. The concept of operation is described in detail and the system performance is evaluated using computer simulation.","PeriodicalId":230802,"journal":{"name":"2008 10th Anniversary International Conference on Transparent Optical Networks","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116858232","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}
