We study shared-memory switches under multicast bursty traffic, and characterize the relation between their performance and the multicast distribution which defines the mix of multicast traffic arriving at the switches. We consider two schemes that have been used in practical realization of these switches to replicate multicast cells: (i) replication-at-receiving (RAR), where multiple copies of a multicast cell are stored in the buffer and served independently, and (ii) replication-at-sending (RAS), where a single instance of a multicast cell is stored in the buffer, and the cell is replicated as it is transmitted to the output ports. For both schemes, using simulation, we find upper bounds for the buffer requirements to achieve a desired packet loss rate. We show that these upper bounds, which are significantly larger than the buffer requirements under unicast traffic, are actually approached under any realistic multicast distribution, and even for small volumes of multicast traffic. We also study shared-memory switches with output demultiplexers, and characterize and compare the different multicasting schemes that are used in these ATM switches.","PeriodicalId":152724,"journal":{"name":"Proceedings of GLOBECOM '95","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123009336","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}

Sharma","doi":"10.1109/GLOCOM.1995.501968","DOIUrl":"https://doi.org/10.1109/GLOCOM.1995.501968","url":null,"abstract":"The ready-to-go virtual circuit protocol (or RGVC) is a novel connection control protocol for gigabit networks that is designed to ensure lossless transmission for delay-sensitive traffic and for traffic whose rate changes with time. The RGVC protocol is one of the two connection control protocols that will be used in the 40 Gbit/s fiber-optic ATM-based Thunder and Lightning network, currently being developed at UCSB. We introduce the RGVC protocol, discuss its main features, and indicate its lossless character. The RGVC protocol can be viewed as a reservation protocol where the reservation and the data transmission phases overlap. The source need not wait for an end-to-end round-trip delay for reservations to be made before transmitting the data. Instead the data packets follow the setup packet after a short offset-interval, which is much smaller than the round-trip delay. As a result, the protocol does considerably better than wait-for reservation protocols in terms of minimizing pre-transmission delay, and is useful for connection establishment for traffic with strict delay requirements. If the setup packet is unsuccessful in reserving the required capacity, or if the rate of the session changes without there being sufficient capacity to accommodate the change, the packets are buffered at intermediate nodes and back-pressure is exercised to the upstream nodes to control the source transmission rate. The back-pressure mechanism uses the concept of freezing of capacity to ensure that the protocol is lossless.","PeriodicalId":152724,"journal":{"name":"Proceedings of GLOBECOM '95","volume":"36 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120913016","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}

Ethernet is the most promising candidate due to its low cost and vast installed base. It, however, is also known as having a capture effect which refers to the phenomena that the losing node in a collision is more likely to loose again, thereby causing long delay variations and disruption of a constant bit-rate (CBR) video stream for an extended period of time. This paper examines the impact of the Ethernet capture effect on video services in a residential environment. Actual PC data traffic was used in a simulation to investigate the impact of jitter caused by the capture effect on video traffic. The results indicate that capture effect rarely occurs in an actual residential, or small business Ethernet LAN, and is likely to occur only when PC performance has improved in the future. The frequencies and duration of the captures are also characterized. The resultant video packet jitter can be removed by a simple playout buffer. The findings suggest that Ethernet can meet the performance requirement of residential network at a very low cost.","PeriodicalId":152724,"journal":{"name":"Proceedings of GLOBECOM '95","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133562369","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}
