Based on an universal physical structure, the digital coherent receiver is compatible with a wide range of modulation formats and propagation scenarios. The key for this flexibility lies on an extensive usage of receiver-side DSP. In this paper we will briefly review the basic principles of the digital coherent receiver, highlighting the role of the DSP subsystem. Special emphasis will be given to the mitigation of nonlinear fibre impairments using advanced digital equalizers.","PeriodicalId":217442,"journal":{"name":"2012 14th International Conference on Transparent Optical Networks (ICTON)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133652327","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 European Union (EU) funded DICONET project extended the GMPLS protocols to carry PLI information by proposing two control plane architectures: distributed and centralized. The architectures for these two approaches have been defined, modules have been developed, and their performance has been evaluated based on emulation for various metrics. Moreover, suggestions on protocol extensions have been submitted to IETF CCAMP. On the other hand, the network evolves to be more heterogeneous in terms of not only types of services and traffic demands but also physical layers. These new challenges addressed by the EU funded project CHRON will need new architectures, the core of which is a cognitive decision system.","PeriodicalId":217442,"journal":{"name":"2012 14th International Conference on Transparent Optical Networks (ICTON)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128829887","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}

These applications inherent distinct features such as either delay-sensitive or delay-tolerant. Immediate reservation (IR) and advance reservation (AR) service models have been proposed for satisfying these applications demand, respectively. AR connection requests book network resources relatively far ahead than when they are utilized. The book-ahead time of AR connections not only exacerbates the provisioning rate of IR connection requests, but also results in disrupting IR connections if they are operating on the resources reserved for AR connections, once AR connections become active. To guarantee the service continuity of IR connections and efficiently utilize the network resources, this paper presents four RWA strategies for a dynamic scenario where connection requests belong to both IR and AR (fixed window) traffic demands. Each strategy exploits the connection holding-time awareness in a different way to improve the network blocking probability (BP), and eliminate disruption of IR connections. The book-ahead time of AR requests is varied to investigate its effect on the provisioning rate of AR and IR connection requests. Simulation results confirm that the proposed RWA strategies are able to improve network BP significantly. Moreover, the network total provisioning rate and consequently the resource utilization can be improved substantially by setting the book-ahead time not more than twice the mean holding-time of AR connection requests.","PeriodicalId":217442,"journal":{"name":"2012 14th International Conference on Transparent Optical Networks (ICTON)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114620510","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}
