The proposed synchronous access strategy effectively exploits the propagation delay parameter to eliminate the packet loss and to improve the system performance. In opposition to relative studies, the proposed protocol considers that the number of control channels in the MCA is less than the number of data channels. This fact provides a less costly implementation, since it requires less receivers per station. An analytic Markovian model for finite population is developed to derive the performance measures. The proposed protocol performance is extensively studied for various network parameters: nodes population, control and data channels. Finally, the performance optimization conditions are analytically explored.","PeriodicalId":282743,"journal":{"name":"2015 International Conference on Optical Network Design and Modeling (ONDM)","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128201850","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 rapidly increasing and changing variety of demands placed on such networks requires that optical networks be increasingly agile and responsive to end-consumer traffic needs. Because of multiple levels of aggregation, the optical core is generally less responsive to changing needs at access levels. We have previously proposed that providing architectural mechanisms that allow the provider to inform the customer of available alternatives enables a co-optimization of network resources jointly by customers and providers, leading to better performance for the customer while utilizing resources more efficiently for the provider. In this paper, we show how optical switching capabilities may be abstracted as services to enable the automatic composability that is required for such a system. We have successfully demonstrated a proof-of-concept prototype of this architecture in the GENI environment, which we briefly describe.","PeriodicalId":282743,"journal":{"name":"2015 International Conference on Optical Network Design and Modeling (ONDM)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123769486","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 paper, we propose a new energy-efficient architecture for 100 Gb/s Ethernet. The rate switching time is reduced using coherent lightwave transmission technologies.

In this paper we propose and evaluate a filterless network architecture for a trunk and branch undersea network topology.

Efficient algorithms exist for rearrangeably non-blocking NoC. However, when realized with integrated optical devices, NoC are typically arranged in topologies that are blocking if a single wavelength is used. Mitigation of the blocking behavior is then achieved by exploiting the wavelength domain, which requires however a novel scheduling paradigm. This paper presents an integrated optical NoC based on a ring topology and realized with multiple resonating microrings (MMR). Scheduling in MMR architecture comprises the conventional matching sub-problem along with wavelength assignment sub-problem, which accounts for the additional constraints due to the wavelength domain. A novel scheduling algorithm based on iSLIP algorithm is proposed for jointly addressing both sub-problems. The iterative Parallel Wavelength Matching (iPWM) algorithm achieves performance similar to a two-step scheduler based on sequential iSLIP and first-fit wavelength assignment, but with a computational complexity lower and independent of the number of wavelengths.","PeriodicalId":282743,"journal":{"name":"2015 International Conference on Optical Network Design and Modeling (ONDM)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115807931","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 first one leverages a simple integer linear programming (ILP) model to design the optimal working-backup structure for each request instantly, while the rest two utilize protected working capacity envelop (PWCE) and spectrum planning to further reduce bandwidth blocking probability (BBP). Moreover, mPWCE-MPP considers the differences among working and backup paths, and ensures that the maximum path-difference (MPD) of a request will not increase dramatically in restoration. Simulation results show that mPWCE-MPP can obtain the best trade-off between BBP and average MPD.","PeriodicalId":282743,"journal":{"name":"2015 International Conference on Optical Network Design and Modeling (ONDM)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123749059","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}
