A hierarchical dynamic resource allocation scheme is periodically applied at each node to every outgoing link, in order to reassign link capacity partitions among various service classes. Local access control rules compute the maximum number of connections of each class that a link can accept, by using the assigned capacity. A call request packet is generated with every connection request, and it is sent along a path from the source to the destination node. Each node traversed checks the presence of the resources needed to accept a new connection, by using the local access control rule. A connection is accepted only if every node on the path has enough resources to support it (also maintaining the quality of service for connections in progress), and it is refused otherwise. The path of the request packet is chosen by using a distributed routing strategy. At every node traversed, an output link is chosen by minimizing a cost function composed by two terms: a \"local\" and a \"global\" one. The local term takes into account the situation of the node by using a simple calculation, whereas the global term holds the aggregate information about the situation of the network, and it is updated and passed along periodically by every node. A complete description of the global scheme and simulation results are reported and discussed.<<ETX>>","PeriodicalId":112111,"journal":{"name":"Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132428824","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}

Another interesting technique is a CDMA system with Rake-receiver. The main advantages of CDMA are well known, but its capacity is limited by multiuser interference. The aim of this study is to analyze the performance of a convolutionally-coded CDMA system combined with OFDM in a frequency/time selective fading channel, taking into account the near-far problem. This combination allows one to perform a maximum-likelihood detection (MLD), to use the available spectrum in an efficient way, to exploit frequency diversity and time diversity (provided by channel coding), and to retain many advantages of a CDMA system with a simpler hardware realization. An example for a mobile communication system using convolutionally-coded CDMA/OFDM with Walsh-Hadamard code-spreading for the downlink (base-mobile) is studied. The performance of a MLD is examined by taking into account the near-far problem. It is shown that the MLD is very robust to the near-far problem. It is also shown that by using BPSK modulation, in a 1.28 MHz bandwidth, one can transmit 64 active users at rate of about 10.34 kbit/sec.<<ETX>>","PeriodicalId":112111,"journal":{"name":"Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132057546","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}

This methodology often leads to the development of different models within different environments constituting different views of the same object. An instance of this problem has been identified in the field of ATM switching, where three switch models are under consideration for the management, control and customer network management (CMN) points of view. None of the models can be considered as exhaustive nor representing the complete physical reality of the equipment. Each of them is presented in the paper with references, where applicable, to the current activity of standardisation bodies and interest groups. A more effective approach consists in facing the problem in an integrated manner, developing a model including at the same time aspects from the different views. This means the study of a single, consistent, complete model of the ATM switch at a suitable level of abstraction, and suggests an architecture where the different representations are mapped onto different views of the same data structure. A possible realization of this approach is sketched, together with an example of management, control and CNM interactions (based on CMIP, signalling and SNMP, respectively) and their impact on the common data structure.<<ETX>>","PeriodicalId":112111,"journal":{"name":"Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130979311","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}
