For the disaster survivable problem in an elastic optical datacenter networks with a bandwidth constraint, we formulate an integer linear program (ILP) for shared protection model. The algorithm utilizes the priori method to maximize the network throughput firstly, and then to minimize used spectrum resources. Unicast and anycast methods in shared protection are investigated. Simulation results show that both methods provide the same network throughput, but the anycast method can use much less spectrum resources than the unicast method.","PeriodicalId":300208,"journal":{"name":"2016 IEEE Optoelectronics Global Conference (OGC)","volume":"191 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131675379","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}
