One is the fuzzy leaky bucket algorithm, where a fuzzy increment controller is incorporated with the conventional leaky bucket algorithm; the other is the neural fuzzy leaky bucket algorithm, where a neural fuzzy increment controller is added with the conventional leaky bucket algorithm. The fuzzy and neutral fuzzy increment controllers properly choose the long-term mean cell rate and the short-term mean cell rate as input variables and by intelligent computation determine the increment value. Three performance measures such as selectivity, responsiveness, and queueing delay are investigated. The intelligent fuzzy leaky bucket algorithms can have a performance that is better than the conventional leaky bucket algorithm. The neural fuzzy leaky bucket algorithm outperforms the fuzzy leaky bucket algorithm.","PeriodicalId":332734,"journal":{"name":"Proceedings 15th International Conference on Information Networking","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126831825","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 IMS system is a personal audio multicast transmission system and provides an interactive environment over the Internet. The IMS server site plays the DJ role and can multicast the DJ's voice and MP3 music to multiple clients. The IMS client site plays the audience role and can receive audio and MP3 music from the IMS server. Additionally, the IMS provides two features using the real time multimedia interaction technique. The first one is that the IMS audience can transmit his voice to the IMS server with a call-in operation. The second one is that the IMS offers the dual server mode to allow a secondary DJ, who is geographically separated from the main DJ, to join the program. That is, two geographically separated DJs cooperatively control the program. Related technical issues and the corresponding system development of the IMS are presented in detail.","PeriodicalId":332734,"journal":{"name":"Proceedings 15th International Conference on Information Networking","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123415175","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}

Data and methods of a class are inherited by lower-level classes according to the is-a hierarchical structure.

It is difficult to specify access rules for every class and object, because the system is composed of various types of classes, and objects which are dynamically created and dropped. If access rules on some class could be reused for other classes, the access rules are easily specified.

When using VOQ, a scheduler is required to decide the switch sequence of cells. We propose a round-robin based parallel scheduling algorithm (T-RRM) for crossbar switches with input queues to reduce the average delay of cells. In T-RRM, marked port is defined. When a queue sends a cell and the number of queued cells in the queue is bigger than a predicted threshold, the corresponding input and output is marked as marked ports. A marked port will send another cell in next one time slot.","PeriodicalId":332734,"journal":{"name":"Proceedings 15th International Conference on Information Networking","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121865209","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}

Such systems can be modeled as concurrent deterministic FSMs (DFSMs). In those protocols, a common input may be taken by some of concurrent DFSMs competitively. In such a case, the global behaviour becomes non-deterministic in general. Conformance testing is typically a black-box testing, i.e. it is based on its specification. Formal methods for deriving conformance test cases are widely recognized as being capable of producing tests with high fault coverage. We propose a conformance testing method based on GWp-method for a sub-class of non-observable non-deterministic FSMs (NFSMs). In this class, the global behaviour of many protocols modeled as concurrent DFSMs can be specified. The proposed method can be used not only for testing NFSMs directly but also for testing concurrent DFSMs whose global behaviour becomes non-observable non-deterministic.","PeriodicalId":332734,"journal":{"name":"Proceedings 15th International Conference on Information Networking","volume":"492 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129863290","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}

However, the IP packets need to be segmented and packaged due to the differences of format and length between IP packet and ATM cell. Therefore, it will increase the processing time and the complexity of the edge router. In this paper, we propose a novel optical IP router (OIR) architecture and switching concept to fast transmit IP packets in an optical network. The non-TDM based OIR employed genetic algorithms (GAs) with time stamps to support the switching of variable-length IP packets. By using the algorithm, we provide an efficient scheduling technique to cope the variable-length packets in non-TDM based environment.","PeriodicalId":332734,"journal":{"name":"Proceedings 15th International Conference on Information Networking","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129076337","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 proposed approach exploits the coarse grained inherent parallelism in GP among relatively autonomous subpopulations. The developed architecture of a distributed collaborative parallel GP (DCPGP) features a single, global migration broker and centralized manager of the semi-isolated subpopulations, which contribute to quick propagation of the globally fittest individuals among the subpopulations; this reduces the performance demands on the underlying communication network, and achieves dynamic scaling-up features. DCPGP exploits the distributed component object model (DCOM) as a communication paradigm, which as a true system model offers generic support for the issues of naming, locating and security of communicating entities of the developed architecture. Experimentally obtained speedup results show that close to linear speedup characteristics of the prototype of DCPGP are achieved on a network of 8 workstations.","PeriodicalId":332734,"journal":{"name":"Proceedings 15th International Conference on Information Networking","volume":"1048 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123148533","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}

Applications for mobile computing require adaptation for best performance under such variable conditions, to make best use of available resources without assuming the minimum set. This paper details a framework developed by the authors for developing and deploying mobile applications. Current systems are able to notify an application to adapt but fail to say how. The application author must provide the actual adaptation mechanism. The authors aim to provide automatic adaptation to suitably constructed mobile applications. The adaptation mechanism is pervasive through the application and system layers providing tight integration of adaptation both vertically (through an application) and horizontally (between applications).","PeriodicalId":332734,"journal":{"name":"Proceedings 15th International Conference on Information Networking","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121399875","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 DiffServ architecture, on the other hand provides QoS guarantee to aggregate of flows, and is more scalable for backbone networks. We propose an integrated environment in which local access networks provide IntServ while backbone networks provide DiffServ. Issues on how to map service classes between these two types of network and how to provide multicast services are discussed and possible solutions are proposed.","PeriodicalId":332734,"journal":{"name":"Proceedings 15th International Conference on Information Networking","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125420978","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}
