The authors address the issue of congestion avoidance in LANs interconnected by a high speed backbone. A congestion-avoidance scheme that requires input gateways to secure permits to the output gateway before transmitting is proposed. An implementation of the proposed congestion-avoidance scheme in an ATM (asynchronous transfer mode) switch is shown. Performance results indicate that packet dropping rates are greatly reduced.<<ETX>>","PeriodicalId":251095,"journal":{"name":"1993 4th Workshop on Future Trends of Distributed Computing Systems","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134269674","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}

In order to cope with the complexity of the system (a tree structure and a multiple association architecture), the authors develop a methodology of structured modeling, based on the abstraction concept. Abstraction is also used for verification purposes. Abstractions based on three equivalence relations (trace, failure, observational equivalence) are considered. Their interest for the modelization and the verification of the provided TP service are shown.

The network is constructed by superimposing the reverse banyan network onto the banyan network. Basic building blocks in the composite banyan network are 3/spl times/3 switching elements (SEs) with log/sub 2/N stages. The major advantage of the composite banyan network over the existing networks with 3/spl times/3 SEs is an efficient and fast control algorithm to set up a path between any source and destination pair. Instead of complex numerical calculations, the network can easily generate a primary routing tag and alternate tags through simple binary operations. It is shown that there exist at least two totally disjoint paths between any source and destination pair, which increases the degree of fault tolerance. In order to increase the possibility of some frequently used permutations, a modified network is also proposed.<<ETX>>","PeriodicalId":251095,"journal":{"name":"1993 4th Workshop on Future Trends of Distributed Computing Systems","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127243219","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}

By combining both concepts, the ISIS system defines causal multicasts in overlapping groups. The authors present a simple and efficient protocol that implements such causal multicasts. It compares favorably to the ISIS protocol, as it uses only one vector of integers (the size of this vector being the total number of groups) to timestamp messages. This low cost in the size of timestamps is obtained by using (sometimes) additional resynchronization messages. It is shown that there is a tradeoff between the delay in the delivery of messages and the size of timestamps carried by messages for timestamp-based protocols implementing causal order.<<ETX>>","PeriodicalId":251095,"journal":{"name":"1993 4th Workshop on Future Trends of Distributed Computing Systems","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133884790","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 emphasis, in this architecture, is on the use of domains to group managed objects and partition the management structure to cope with very large scale inter-organizational distributed systems. Another key aspect of the architecture is a policy service to support the specification, storage and manipulation of policies which can be used to influence the behavior of automated managers. The architecture advocates the use of object-based distributed processing techniques for management and essentially extends the OSF DME approach to cater to domains and policies as underlying management services for all aspects of management.<<ETX>>","PeriodicalId":251095,"journal":{"name":"1993 4th Workshop on Future Trends of Distributed Computing Systems","volume":"516 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116218791","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}
