The spectrum concept is implicit in L.E.N. Delbrouck's (1981) recursions for homogeneous and heterogeneous traffic and has its roots in Hayward's rather simplistic, yet accurate, method for treating homogeneous peaked traffic. The Poissonian-spectrum representation is not unique. To determine the sensitivity of the method to the spectrum shape, a study is made of three distinctly different representations. With appropriate selection of the spectrum shape, the method reduces to simple recursions. A layman's approach is used to derive these recursions as a natural extension of the Roberts-Kaufman recursion. The case of smooth traffic requires careful considerations, which are discussed.<<ETX>>","PeriodicalId":275763,"journal":{"name":"IEEE INFOCOM '89, Proceedings of the Eighth Annual Joint Conference of the IEEE Computer and Communications Societies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129638755","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 interface between the integrated voice subnetwork and the cable system is realized by a metropolitan area gateway (MAG) which is implemented at the broadband cable head-end. In T-SWIFT, an intelligent scheduling algorithm in the MAG dynamically allocates channel bandwidth using a variation of the data switch-filtering and fixed-frame synchronous voice/data integration techniques introduced by the author (see IEEE J. Selected Areas in Commun. vol., SAC-5, no.9, p.1391-1402 (1987)). The MAG accomplishes this by coordinating the transmission of inbound and outbound voice talkspurts in an upwardly compatible fashion with respect to the existing CSMA/CD data stations. Thus previously installed stations require no modification. Results are presented which indicate that the T-SWIFT design performs significantly better than previous compatible voice/data integration methods.<<ETX>>","PeriodicalId":275763,"journal":{"name":"IEEE INFOCOM '89, Proceedings of the Eighth Annual Joint Conference of the IEEE Computer and Communications Societies","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122637439","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}

Analysis shows that the performance of packet queuing delay at switch input, as well as the entire throughput of the switch, can be adversely affected by such imbalances. The work is then extended to examine a transient imbalance case, where the switch experiences the alternation of two transient periods, each at a different traffic imbalance mode. The alternation is modeled by a two-state Markov chain. Both balanced and imbalanced cases can be viewed as the two extremes of the transient case. It is observed that the system throughput and the queuing performance in the transient case heavily depend on both mean sojourn time and steady-state probability at each imbalance mode.<<ETX>>","PeriodicalId":275763,"journal":{"name":"IEEE INFOCOM '89, Proceedings of the Eighth Annual Joint Conference of the IEEE Computer and Communications Societies","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123028959","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}

Three classes of adaptive window schemes, all of which use implicit detection, are examined. In all of them, receiving a REJECT frame (which is sent by the far end when it receives an out-of-sequence frame) is interpreted as a sign of congestion, and the control action taken by the end-systems is in the form of reducing their layer-2 window. It is shown that these schemes perform fairly well over a wide range of network parameters and traffic patterns, with one in particular providing a very robust performance over the range. It involves reducing the window size to 1/2 upon receiving a REJECT frame.<<ETX>>","PeriodicalId":275763,"journal":{"name":"IEEE INFOCOM '89, Proceedings of the Eighth Annual Joint Conference of the IEEE Computer and Communications Societies","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131491166","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}

Channel load sensing is viewed as a method of estimating the interference at the receiver based on the interference measured at the transmitter. To do this, a bivariate probability distribution function of the interference at the two locations is required. The probability of packet success is then determined. Since it is difficult to evaluate numerically, a program was written to simulate it. The author gives simulation results for the case of a random network.<<ETX>>","PeriodicalId":275763,"journal":{"name":"IEEE INFOCOM '89, Proceedings of the Eighth Annual Joint Conference of the IEEE Computer and Communications Societies","volume":"356 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131607506","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}

At very light loads, the protocol behavior is similar to a random-access scheme with zero packet delay. As load increases, the operation is similar to an implicit token-passing scheme and ensures fair round-robin scheduling among stations. The protocol is completely distributed, with no station performing any special function. When collisions occur, one station always continues its transmission to completion. Thus, the wastage of bandwidth caused by collisions is minimized. This is achieved using active and passive switches on the buses. Delay performance of Z-NET is superior to Expressnet. Fasnet and tokenless protocols at very light loads. At heavy load, performance is similar to that of Expressnet, with bounded packet delay. No special mechanisms are used to start new rounds or for transition between random and controlled access modes of transmission. Thus, the proposed scheme has the added advantage of simplicity.<<ETX>>","PeriodicalId":275763,"journal":{"name":"IEEE INFOCOM '89, Proceedings of the Eighth Annual Joint Conference of the IEEE Computer and Communications Societies","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132317149","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}

A voice scheduling scheme is proposed and evaluated. In this scheme, active voice calls are organized using a distributed global queue. Access scheduling overhead is reduced by voice packet arrival anticipation. To guarantee fairness and to reduce variance of the waiting time, the voice packet build-up during the overhead period is fairly shared among all calls by a round-robin service discipline. Three different voice packet service cases, namely nonexhaustive, exhaustive, and no-queueing, are evaluated. Simple closed-form approximation formulas have been proposed which show good agreement with simulation. The proposed scheme is shown to have performance approaching that of the centralized system.<<ETX>>","PeriodicalId":275763,"journal":{"name":"IEEE INFOCOM '89, Proceedings of the Eighth Annual Joint Conference of the IEEE Computer and Communications Societies","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114566878","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}
