We also discuss the resource hierarchy for GMPLS for heterogeneous interfaces. In particular, we propose methods for resource mapping at incoming and outgoing switching interfaces where data flows with labels of different granularities are aggregated into a single large bandwidth. To reserve bandwidth with different granularities, each node performs logical resource aggregation using label association to map incoming labels onto outgoing labels. Using this concept, we can control and manage data flows with several labels, i.e. different resources, inside a GMPLS control domain","PeriodicalId":293442,"journal":{"name":"The 7th International Conference on Advanced Communication Technology, 2005, ICACT 2005.","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130328462","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}

Following chapter introduces a few data structure as well as general tree type and why general tree is used to meet the goal. Then, source code written in C illustrates how the general tree is used to be able to modify the UI menu structure with some of examples. The primary goal of the algorithm is to help end-users and programmers to be able to modify the UI menu structure.

It is shown here that the preferred characteristics of the complex family, in terms of probability of error, are partially carried over to the real and imaginary components when considered to be real-valued sequences, and intermediate improvement in probability of error is retained. Clearly the use of real-valued sequences results in reduced complexity in implementation. The improvement in probability of error is gauged with reference to two Gaussian approximations from the literature for the interference limited case, as well as with reference to control experiment randomly drawn sequences constructed by cointossing and drawing from the Gaussian distribution. The focus on the interference limited case where noise is suppressed allows one to observe the improvement yielded by the technique. The major parameters of the system are N, the sequence length, and q, the family size. Results from simulations are presented, demonstrating enhanced performance. The Gaussian approximations used for comparison are shown to underestimate the probability of error for the control experiment sequences while the generated real sequences have augmented performance with the complex sequences superior","PeriodicalId":293442,"journal":{"name":"The 7th International Conference on Advanced Communication Technology, 2005, ICACT 2005.","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127880237","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}
