A distributed control plane based on the generalized multiprotocol label switching (GMPLS) suite is considered for disseminating link-state information and reserving network resources. Different routing and wavelength selection strategies are proposed and a detailed performance analysis is carried out during restoration. Simulation results evaluate the blocking probability due to both lack of available resources (i.e., forward blocking) and resource contentions (i.e., backward blocking). Performance comparison provides some insightful suggestions to be applied to GMPLS-controlled wavelength-routed networks without wavelength converters. First, it is recommended to perform routing and wavelength selection separately at the lightpath source and destination, respectively. Second, routing can be computed on link-state information advertised during provisioning, without the need of flooding link-state information during restoration. In fact, during restoration, the resource contention among concurrent signaling instances is the dominant cause of blocking (i.e., backward blocking overcomes forward blocking). For this reason, intelligent routing and wavelength selection strategies aiming at avoiding or limiting resource contentions can help to improve restorability. In particular, among those strategies, the proposed wavelength selection has a better ability to reduce resource contentions than the routing strategies.","PeriodicalId":49154,"journal":{"name":"Journal of Optical Networking","volume":"7 1","pages":"388-399"},"PeriodicalIF":0.0,"publicationDate":"2008-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1364/JON.7.000388","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66588289","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}

Recently, the path computation element concept has been proposed to generalized multiprotocol label switching controlled optical borne networks to make routing decisions for interdomain connections taking into account traffic engineering, quality of service, and resilience considerations. Still the question of protection shareability emerges. For dedicated protection it is enough to know the topology of the network to be able to calculate disjoint paths. However, to reduce network resource usage by sharing of protection resources (e.g., end-to-end shared protection) it is also mandatory to know the exact working and protection path pairs for all the demands. This can be checked within a domain where not only the full topology and link-state information is flooded but also the working and protection paths are known for each connection; however; over the domain boundaries for security and scalability reasons no such information is being spread. We propose using two techniques that do not require flooding the information on working and protection paths while still allowing the sharing of resources. These two techniques are the multidomain p-cycles and the multidomain multipath routing with protection. After explaining the principles of these methods we evaluate the trade-off between the resource requirement and availability of these techniques by simulations.","PeriodicalId":49154,"journal":{"name":"Journal of Optical Networking","volume":"7 1","pages":"400-409"},"PeriodicalIF":0.0,"publicationDate":"2008-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1364/JON.7.000400","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66588480","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 scheme uses the broadband amplified spontaneous emission spectra of the RSOA for the transport of the local area network traffic among the customers, while the second scheme uses the optical carriers delivered to each optical network unit from the central office for the wavelength seeding of the RSOA to facilitate the transport of the local area network traffic. The third scheme describes the self-seeding process of the RSOA with the use of fiber Bragg gratings placed at the optical network unit to facilitate the upstream access and local area network traffic. These schemes for optical layer local area networking among the customers are experimentally demonstrated with more than 2Gbits/s downstream data, 1Gbit/s upstream access traffic, and 1Gbit/s local area network traffic. Moreover, the results of the experiments of all three schemes are compared further and discussed in terms of bandwidth of the local area network traffic, seeding optical power into the reflective semiconductor optical amplifier, and power budget.","PeriodicalId":49154,"journal":{"name":"Journal of Optical Networking","volume":"7 1","pages":"513-532"},"PeriodicalIF":0.0,"publicationDate":"2008-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1364/JON.7.000513","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66588972","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 networks thus need to support differentiated recovery schemes fulfilling those requirements while achieving efficient network performance (e.g., resource usage). We specifically focus on dedicated path protection (DPP) and shared path protection (SPP) recovery within generalized multiprotocol label switching (GMPLS) all-optical networks. In this context, the standard GMPLS open shortest path first-traffic engineering (OSPF-TE) protocol does not convey the required routing information in order to achieve a desirable network performance. The novelty of this work is twofold. First, to present enhanced GMPLS routing approaches for both SPP and DPP recovery schemes that, besides maximizing resource usage, also address connection blocking mostly due to the wavelength continuity constraint. Second, to evaluate these implemented schemes in a real experimental ION named ADRENALINE testbed. A detailed description of the routing approaches along with their required extensions to current GMPLS OSPF-TE is provided. The experimental performance comparison is conducted considering three figures of merit: connection blocking probability, restoration overbuild, and connection setup delay. The evaluation of the aforementioned schemes may help network operators to select a survivability scheme for a given client.","PeriodicalId":49154,"journal":{"name":"Journal of Optical Networking","volume":"7 1","pages":"496-512"},"PeriodicalIF":0.0,"publicationDate":"2008-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1364/JON.7.000496","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66588881","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}
