DTM is designed for real-time multimedia applications and for high-speed computer communication. DTM provides a service with real-time guarantees: it allows reservation of bandwidth, and has constant delay between two nodes. DTM uses a novel medium-access technique and provides a multicast channel service. The paper describes how resources are reserved in DTM, and describes a DTM prototype implementation to demonstrate that the protocols can be implemented efficiently.<<ETX>>","PeriodicalId":206154,"journal":{"name":"First IEEE Symposium on Global Data Networking","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121908337","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 policies differ in the amount of information used by the bus arbitrator to decide which input queue to serve next. Classical polling systems (e.g. Round-Robin) consider only the state of the input queues. This may waste bus bandwidth on cells that are destined to output queues which are full. The present authors consider a range of bus service policies that are based on the state of the input queues, or the state of both the input and the output queues. The performance of the switch is analyzed under realistic system characteristics such as bursty traffic, limited buffer size, asymmetric load conditions, and nonuniform destinations. Input traffic is modelled by an interrupted Bernoulli process (IBP). Furthermore, it is assumed that the destinations of the arriving cells within the same burst are correlated. Two types of destination correlations are introduced and their effect on the performance of the switch is analyzed. The performance measures considered are: cell loss probability, and mean cell delay.<<ETX>>","PeriodicalId":206154,"journal":{"name":"First IEEE Symposium on Global Data Networking","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127568106","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}

Security features such as access control and authentication are critical to both the CNM service provider and the customer.

ATM switching technology is an attractive candidate for the interconnecting medium because high-speed switches can be built at relatively low cost. A competing technology is DQDB, which is the IEEE 802.6 standard for Metropolitan Area Networks. A model is developed to study the performance differences of ATM switches and DQDB when used as interconnecting media.

This has implications on the overall systems' architecture as well as on the host. From the user perspective the end-system will be shaped by the application and become a global distributed shared-memory multiprocessor. In this paper we propose a memory building block based on optical networking technology that we further use in devising a multiprocessor host architecture. A hierarchical memory architecture that ensures scalability and allows multiple copies of a shared object is adopted. The architecture favours hardware solutions for enforcing cache coherence by exploiting the intrinsic broadcast capability of the new memory module. The interprocess communication system suitable for such an environment is analysed in order to achieve functional transparency for applications ported from a multicomputer to a multiprocessor, and issues related to performance transparency when dealing with long light-propagation latency are addressed. With this processing-communication paradigm, the host-network interface simply provides a direct path between the host-memory and the external network-memory.<<ETX>>","PeriodicalId":206154,"journal":{"name":"First IEEE Symposium on Global Data Networking","volume":"15 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131859232","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}
