The debate as to which of the two kinds of factors dominates the overall performance has been going on for many years. The author discusses this issue by reporting on detailed performance measurements of his experimental OSI transport system. He focuses on the analysis and classification of the path lengths involved during data transfer, obtaining insight into the relative costs of protocol functions versus system-level design and implementation choices. His main conclusion is that adherence to general-purpose protocol standards is not the true bottleneck. The desire to provide a flexible general-purpose portable implementation with open inter-layer interfaces causes most of the overhead.<<ETX>>","PeriodicalId":163373,"journal":{"name":"[1991] Proceedings 16th Conference on Local Computer Networks","volume":"151 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125890050","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 authors present techniques for managing network resources and processing messages in a predictable fashion. Their solutions use a novel structure for the protocol processing software, and they examine several alternatives and discuss the engineering tradeoffs associated with each. Using simulation, they evaluate their protocol processing structures and show that the more sophisticated structures can improve the response time and predictability of time-constrained messages. The ideas presented in this paper can be applied to resource management in the operating system and to the structuring of application-level servers. The designers of gateway machines (for internetwork routing) which handle both time-constrained traffic and non-time-constrained traffic may also benefit from this study.<<ETX>>","PeriodicalId":163373,"journal":{"name":"[1991] Proceedings 16th Conference on Local Computer Networks","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128505239","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 system is network independent, in the sense that it runs on any of the local networks currently available on the market, and location transparent, as any mapping between processes and machines is allowed, including the extreme case of a standalone system where all processes run on the same machine. It is believed that the system is interesting from the perspective of designing a network independent distributed system, and also from a software engineering point of view, as its modular design permits simpler development, debugging and testing, as well as future extensibility.<<ETX>>","PeriodicalId":163373,"journal":{"name":"[1991] Proceedings 16th Conference on Local Computer Networks","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130060060","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 authors describe problems associated with the design of optically switched WDM networks, study the embedding of regular virtual topologies into regular and irregular physical topologies, tabulate some characteristics of embedded regular virtual topologies and provide a procedure for computing the maximum number of wavelengths required for virtual topology embeddings.<<ETX>>","PeriodicalId":163373,"journal":{"name":"[1991] Proceedings 16th Conference on Local Computer Networks","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114506817","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 front-end processor system (FEP) is designed for operation in a CLN/LLC 1 environment, and implements the ISO OSI TP4 transport protocol. The FEP uses one or more commercial microprocessors with layers 2b-4 implemented in firmware. The protocol processors are supported by custom VLSI hardware such as a checksummer, DMA units, and process coupling devices as required. Layers 1 and 2a are provided by commercial chipsets. The FEP is optimised for a LAN/MAN environment while allowing the host to communicate over wide-area networks. It is general enough to be adapted to non-OSI protocol suites. Initial estimates indicate that the FEP should be able to transmit and receive at full FDDI bandwidth with a TPDU length of 1k octets.<<ETX>>","PeriodicalId":163373,"journal":{"name":"[1991] Proceedings 16th Conference on Local Computer Networks","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128758329","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}

So, effective communication protocols that encounter for several traffic and performance characteristics need to be developed in order to meet the required QOS (quality of service) for the various types of traffic carried. Moreover, the interactions among protocols of different communication layers have to be examined in order to ensure an efficient and high performing operation. The authors are concerned with the bandwidth allocation protocol problem. They address some recently developed approaches to the problem, and examine the two lower layers of a communication subnetwork. They consider the call and packet/cell layers where they assume that two types of traffic are carried. They propose a threshold based approach to the call admission problem in the call level and examine the need for flow control in the packet/cell level. They examine various performance measures and show that the correct choice of performance measures and the sizing of the various network parameters play a significant role in a network operation.<<ETX>>","PeriodicalId":163373,"journal":{"name":"[1991] Proceedings 16th Conference on Local Computer Networks","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126208981","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 paper describes a design of an 'almost-all' optical local-area network that is capable of providing Gbps directly to the user. The network design is based on the 802.6 topology, the 'field coding' technique (in which the header and the data fields are encoded in different rates), and the principle of 'almost all' optical switching. Several of the design considerations were: cost, integration, and flexibility. By providing all of these attributes, the optical distribution channel may be an example of future high-speed local area networks, in line with the FDDI-follow on effort.<<ETX>>","PeriodicalId":163373,"journal":{"name":"[1991] Proceedings 16th Conference on Local Computer Networks","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125542009","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}
