This problem can be prevented by careful selection of insulating materials. Dissipation factor and dielectric constant for FEP, PVC, and ECTFE were measured at frequencies from 1 kHz to 300 MHz at 20 degrees C and 60 degrees C. Increases in values for these properties can be related to increases in cable attenuation observed at elevated temperatures.<<ETX>>","PeriodicalId":163373,"journal":{"name":"[1991] Proceedings 16th Conference on Local Computer Networks","volume":"16 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":"132978592","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}

FDDI has such needs at the network to host computer interface. This paper presents design alternatives for the network interface and a model that can be used to examine the achievable throughput assuming different CISC and RISC processors. The model indicates that the CISC processors may outperform the RISC processors in FDDI and other high speed networks where data movement requirements are significantly larger than the protocol processing overhead.<<ETX>>","PeriodicalId":163373,"journal":{"name":"[1991] Proceedings 16th Conference on Local Computer Networks","volume":" 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132011079","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}

Due to the nature of messages, preferences are usually given to voice packets in most implementations of 802.5 standard. Although such an approach is reasonable, it results in ill network resources utilization and inefficient bandwidth distributions among data and voice stations. The authors present a new protocol based on IEEE 802.5 standard that efficiently distributes the network bandwidth between data and voice stations. The results of simulation show that the new protocol achieves the peak data delay improvement when voice traffic is about half of the full load, and achieve none or little data delay improvement when voice traffic is heavy. In other words, the new protocol exploits a better utilization of network resources.<<ETX>>","PeriodicalId":163373,"journal":{"name":"[1991] Proceedings 16th Conference on Local Computer Networks","volume":"18 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":"126915796","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 proposes a protocol which combines the features of transparency and shortest path. The result is a bridge which supports self learning and distributed routing computation.

It is based on HDLC-like frames including the 'bit stuffing' mechanism. HDLC is basically a synchronous transmission oriented protocol, used here however to transmit an asynchronous flow of characters. The automatically inserted 'flags' maintain a 'data carrier' when no data character is pending for transmission. The modem described has been primarily designed for providing a low-cost, low-energy, continuous high-speed data communication channel between moving automatic vehicles (AGV's) and static infrastructures (AGV traffic control).<<ETX>>","PeriodicalId":163373,"journal":{"name":"[1991] Proceedings 16th Conference on Local Computer Networks","volume":"10 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120847576","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}

Fault tolerance is built by linking a LAN to two bridge ports located on two different processing elements, respectively. Two load-partitioning schemes are developed to prevent multiple copies of an arriving frame. A static partitioning scheme requires little hardware or software augmentation. However, the load may not be balanced due to non-uniform traffic patterns. On the other hand, a dynamic partitioning scheme can offer dynamic load balancing, although it requires mechanisms to monitor the traffic and to synchronize inter-processor communication. The bridge performance in terms of frame response time is evaluated through simulation. In the simulation, the impact of the two partitioning schemes on bridge performance are compared. Finally interprocessor synchronization cost is analyzed.<<ETX>>","PeriodicalId":163373,"journal":{"name":"[1991] Proceedings 16th Conference on Local Computer Networks","volume":"9 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":"123317160","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}

Failure symptoms include failure to initialize the ring (make a token), false re-initialization of the ring, and the inability of certain stations to communicate with other stations. These problems were recognized and some solutions for simple cases are included in the FDDI standards Additional cases result from common usage of station addresses which are not solved by the standard algorithms. For example, stations may have multiple individual addresses and may use some addresses as destination addresses but not source addresses. These more complicated fault cases and solutions for them are discussed.<<ETX>>","PeriodicalId":163373,"journal":{"name":"[1991] Proceedings 16th Conference on Local Computer Networks","volume":"57 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":"134253909","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 parameter has the advantage of being simple, policeable and allows the use of linear connection acceptance control algorithms.<<ETX>>","PeriodicalId":163373,"journal":{"name":"[1991] Proceedings 16th Conference on Local Computer Networks","volume":"26 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":"115640091","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}
