Moving the radio operating frequency into the mm-wave region overcomes the spectral congestion in the lower microwave region and is also capable of providing high-capacity broadband wireless services in a picocellular or microcellular architecture. Optical fiber backhaul provides the broadband interconnectivity between a centralized location and a large number of high-throughput antenna base stations necessary in such an architecture. The transportation of mm-wave wireless signals within the hybrid network is subject to numerous impairments ranging from low conversion efficiency to fiber chromatic dispersion and also to signal degradation due to nonlinearity along the link. One of the major technical challenges in implementing these networks lies in the mitigation of these impairments that the wireless signals experience while traversing the links. In this paper, we present an overview of the different techniques and schemes to overcome some of the impairments for transporting mm-wave signals over optical fibers.","PeriodicalId":49154,"journal":{"name":"Journal of Optical Networking","volume":"8 1","pages":"201-214"},"PeriodicalIF":0.0,"publicationDate":"2009-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1364/JON.8.000201","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66592860","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}

Chou","doi":"10.1364/JON.8.000033","DOIUrl":"https://doi.org/10.1364/JON.8.000033","url":null,"abstract":"As Internet traffic continues to grow unabated at an exponential rate, it is unclear whether the existing packet-routing network architecture based on electronic routers will continue to scale at the necessary pace. On the other hand, optical fiber and switching elements have demonstrated an abundance of capacity that appears to be unmatched by electronic routers. In particular, the simplicity of circuit switching makes it well suited for optical implementations. We present what we believe to be a new approach to optical networking based on a paradigm of coarse optical circuit switching by default and adaptive rerouting over circuits with spare capacity. We consider the provisioning of long-duration quasi-static optical circuits between edge routers at the boundary of the network to carry the traffic by default. When the provisioned circuit is inadequate, excess traffic demand is rerouted through circuits with spare capacity. In particular, by adaptively load balancing across circuits with spare capacity, excess traffic is routed to its final destination without the need to create circuits on the fly. Our evaluations on two separate real, large Internet service provider point-of-presence-level topologies, Abilene and GEANT, show that only a very small amount of excess traffic needs to be rerouted even during peak traffic hours when the circuit configurations are carefully chosen and that this excess traffic could always be accommodated using our adaptive rerouting approach. We also demonstrate that our adaptive load-balancing approach is robust to sudden unexpected traffic changes by demonstrating its ability to reroute traffic under a number of hot-spot scenarios.","PeriodicalId":49154,"journal":{"name":"Journal of Optical Networking","volume":"8 1","pages":"33-50"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1364/JON.8.000033","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66592293","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 work, we focus on packet contention prevention in an optical packet-switched network, tackling the problem from the perspective of a network-wide end-to-end label-switched path (LSP) admission control and LSP-to-wavelength assignment. We present two contention-preventing wavelength assignment schemes, called minimum interference (MI) schemes, that can be implemented within a network control plane based on a generalized multiprotocol label switching (GMPLS) protocol suite. MI schemes envision that LSP-to-wavelength assignment is accomplished by a novel ranking policy utilized for the tie breaking of the GMPLS label set (i.e., the available wavelength set). Specifically, the novel GMPLS object named the suggested vector (SV) is populated during forward propagation of the path message, collecting, for each wavelength, the amount of bandwidth not interfering with already-established LSPs. During the backward propagation of the Resv message, the actual LSP-to-wavelength allocation is performed based on the preference level stored in the SV object. Numerical results show that MI schemes are effective in decreasing end-to-end packet loss and wavelength conversion probabilities, compared with the no-preference scheme that does not exploit such optimization.","PeriodicalId":49154,"journal":{"name":"Journal of Optical Networking","volume":"8 1","pages":"14-25"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1364/JON.8.000014","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66592160","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}
