In ATM networks, all information is packetized and transferred in small packets of fixed length, called cells. The packetized information transfer, without flow control between the user and the network and the use of statistical multiplexing, results in the need of a policing mechanism to control the traffic parameters of each virtual connection in order to guarantee the required quality of service (QoS). The proposed parameters for monitoring the source traffic characteristics are the mean cell rate, the peak cell rate or the peak burst duration. Policing of the peak cell rate is generally not complex and can be achieved by using a cell spacer or other policing mechanisms (PMs). Monitoring the mean cell rate is more difficult. It is intended to improve the link utilization when it has to handle bursty traffic sources. We propose a policing mechanism called the fuzzy policing mechanism (FPM), by applying fuzzy set theory to police the mean cell rate of the still picture source in ATM networks. The performance evaluation via simulation shows that the FPM efficiently control the mean cell rate of the still picture source. The proposed FPM shows a good response behavior against parameter variations. The selectivity characteristics of the FPM approach the ideal characteristics required for a PM.","PeriodicalId":420811,"journal":{"name":"Proceedings of LCN - 21st Annual Conference on Local Computer Networks","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128560678","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 propose a neural-network-based intra-media synchronization mechanism, called neural network smoother (NNS). The NNS is composed of a neural network (NN) traffic predictor, an NN window determinator, and a window-based playout smoothing algorithm. The NN traffic predictor employs an on-line-trained backpropagation neural network (BPNN) to periodically predict future traffic characteristics. With the predicted traffic characteristics, the NN window determinator determines the corresponding optimal window by means of an off-line-trained BPNN in an effort to achieve a maximum of the playout quality (Q) value. The window-based playout smoothing algorithm then dynamically adopts various playout rates according to the window and the number of packets in the buffer. Compared to two other playout approaches, simulation results show that NNS achieves high-throughput and low-discontinuity playout under a variety of traffic arrivals.","PeriodicalId":420811,"journal":{"name":"Proceedings of LCN - 21st Annual Conference on Local Computer Networks","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124000879","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}

For multicast communication on ATM LANs, the architecture of the switch fabric and protocols for signaling have been studied. However, when data communication using a multicast connection such as a LAN emulation service which expects the high throughput is provided, ABR (available bit rate) service on a multicast connection (multicast ABR) is also required. ABR service has been actively discussed in the ATM Forum. Unfortunately, the study on flow control mechanism for multicast ABR is not sufficient. This paper discusses a suitable flow control mechanism for multicast ABR and shows its performance. At first, it summarizes the approaches for the flow control and describes the outline of the proposed mechanism based on the suitable approach. Next it evaluates the performance and shows the effectiveness of the mechanism by simulations. Moreover, after pointing out the importance of operations in the case of link failures on the multicast tree, it discusses the cooperation in this case between the flow control and the related functions to detect these failures.","PeriodicalId":420811,"journal":{"name":"Proceedings of LCN - 21st Annual Conference on Local Computer Networks","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121874534","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 analyze the performance by simulations of ATM switch based on Banyan network in the uniform traffic condition. We compare the analytical results obtained from the three-state model by Yan and Jenq (see MS Thesis, Dept. of Electrical and Computer Engineering, Portland State University, Portland, Oregon, 1995) to the simulation results. We propose non-blocking first stage (NBFS) to increase the throughput. In the NBFS scheme, internal blocking in the switching element (SE) of the first stage is avoided. We extend the idea of the priority scheme proposed by Yan and Jenq by proposing an enhanced priority (EP) scheme. In the EP scheme, we give priority to the packet blocked the greater number of times. We simulated the switch with a combined NBFS and EP scheme. The results shows that the throughput increases, and the variance of delay decreases significantly. We simulated the single buffer Banyan network with mixed voice and data traffic We simulated the Banyan network with the proposed double buffer switching element to increase the throughput and decrease the delay and variance of delay, of delay sensitive voice packet in a mixed traffic condition.","PeriodicalId":420811,"journal":{"name":"Proceedings of LCN - 21st Annual Conference on Local Computer Networks","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133935280","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}
