The Survivable Adaptable Fiber Embedded Network (SAFENET) is used as the main vehicle of this study.<<ETX>>","PeriodicalId":270137,"journal":{"name":"Proceedings of 19th Conference on Local Computer Networks","volume":"27 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115771007","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}

Now, applications have started to exceed the capabilities of these low speed LANs. A new generation of high speed networks are being deployed to meet with increasing expectations of users. This paper compares four such high speed LANs which operate at or above 100 Mb/s: 100BASE-T, 100VG-AnyLAN, FDDI and ATM. The attributes and performance of these four LANs are described and contrasted. The implications of migration to these new technologies are discussed.<<ETX>>","PeriodicalId":270137,"journal":{"name":"Proceedings of 19th Conference on Local Computer Networks","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129879992","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 enterprise serving, an interconnected set of specialized and heterogeneous servers provide the computational and storage needs of client workstations, all in a transparent fashion. Asynchronous transfer mode (ATM) has the promise of capturing the total network upon which enterprise serving operates. That is, ATM can be deployed from the workstation all the way to the server. Current servers are not designed for handling high bandwidth multimedia traffic and effectively delivering the high bandwidth of the ATM network to the processor boards where applications reside. It is feasible that extending ATM into the server as the interconnect fabric and communication architecture will be a solution. This solution is further analyzed and simulation results are reported.<<ETX>>","PeriodicalId":270137,"journal":{"name":"Proceedings of 19th Conference on Local Computer Networks","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122823987","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}

Feedback from verification analysis can be very useful to protocol designers, but it is often difficult to stay current with the protocol's development. Our approach facilitates quick turnaround in the development and verification process-even before the protocol is stable. American National Standards Committee X3T9.3 has chartered the development of Fibre Channel (FC), a proposed standard for serial I/O channel capable of supporting a wide range of zipper layer protocols. Despite the complexity of FC, we have used our approach to both verify it and to produce a software and hardware implementation of the protocol. We describe features that enable rapid turnaround in response to revisions of the standard and maintenance of a stable suite of test cases for the standard. The approach has also been applied to other protocols.<<ETX>>","PeriodicalId":270137,"journal":{"name":"Proceedings of 19th Conference on Local Computer Networks","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126295279","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 introduces PDQRAP, a prioritized version of DQRAP. Two formats, the extra-bit and the extra-slot, each a variation of the basic DQRAP are described. Simulation results are presented that show that under a total traffic load of 90%, a high priority segment of 20%-30% in either format has delay characteristics ranging from one-third to one-half of the delay characteristics of the normal priority traffic. The relative advantages and disadvantages of each format ore discussed. It is suggested that PDQRAP could be the mechanism that allowed a shared medium to economically transport traffic associated with multi-media services utilizing LANs, MANs, and WANs.<<ETX>>","PeriodicalId":270137,"journal":{"name":"Proceedings of 19th Conference on Local Computer Networks","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115209104","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 particular. After a discussion of the various schemes, we analyzed the bandwidth advertising criterion both by analytical methods and simulation. The cell loss and packet loss probability have been evaluated as a function of the usual network parameters (number of users, packet length, burstiness, etc.), pointing out that the gain factor of the network (i.e., the number of multiplexed sources given the quality of service) is directly proportional to the source burstiness. This intuitive result can be efficiently exploited in ATM LAN environments, where, it is supposed that a significative portion of traffic comes from bursty users.<<ETX>>","PeriodicalId":270137,"journal":{"name":"Proceedings of 19th Conference on Local Computer Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129515781","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}

We examine what shaping may be considered ideal, and what is attainable under the constraints of transmission systems and cost. We justify the use of FCFS multiplexing of multiple single-stream shaper outputs as a performance reference for multi-stream shapers, but also point out some of its deficiencies. Shaper implementations in which transmissions are scheduled on cell arrivals, emissions, and transmissions are examined and compared both qualitatively and through simulation. We identify the problem of shaping cells that must conform to multiple traffic constraints (e.g. when the rate of a multicast connection must be adapted to suit multiple links) and examine implementations to achieve this. Shaping in which inevitable cell delay variation is intentionally distributed inequitably amongst connections (to assist CDV-intolerant connections) is also examined.<<ETX>>","PeriodicalId":270137,"journal":{"name":"Proceedings of 19th Conference on Local Computer Networks","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126724630","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}
