In this paper we demonstrate through analysis and simulation the need for a hierarchical architecture for the video-on-demand distribution network. We assume a hierarchical architecture, which fits the existing tree topology used in today's cable TV (CATV) hybrid fiber/coaxial (HFC) distribution networks. We develop a model for the design, configuration, program placement and performance evaluation of such systems. The model takes into account the user behavior, the fact that the user re quests are transmitted over a shared channel before reaching the video server containing the requested program, the finite input/output (I/O) capacity of the video servers, the exponential storage cost of the multimedia programs imposed by the adopted architecture of the video-on-demand distribution network, and finally the communication cost. In addition, our model allows batching of user requests at the video server and we study the effect of batching on the performance of the video server and on the delivered to the user Quality of Service (QoS). The design and evaluation is based on an extensive analytical and simulation study. The results in this paper contribute to the understanding of the tradeoffs between quality of service, server I/O, storage required, program placement, and commu nication cost. They are helpful in configuring the VOD dis tribution network, optimally placing the programs across the hierarchy of the video servers, and maximizing the performance of the overall system.","PeriodicalId":178651,"journal":{"name":"The Fourth IEEE Workshop on High-Performance Communication Systems","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122336345","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 many cases, the problem of congestion control (a major research issue otherwise) does not exist because downlink bandwidth is \"owned\" or can be preallocated to a particular server by independent means, but the problems of insuring reliable data delivery to larcre groups, and adaptability to heterogeneous clients, still remain. These problems can be solved at once with the use of FEC techniques. In this paper we show the design of a Reliable Multicast data Distribution Protocol (RMDP) that we have built using these techniques, and discuss the implementation tradeoffs. Experimental results show that, albeit somewhat expensive, doing encoding/decoding in software is affordable for speeds in the Mbit/s range even on low-end PCs. Slower machines can still receive at high speed, thus optimizing network usage, by taking advantage of the fact that decoding needs not to be done in real time. Finally, our RMDP can work even without any feedback from the receivers, thus making it well suited to mobile/wireless systems.","PeriodicalId":178651,"journal":{"name":"The Fourth IEEE Workshop on High-Performance Communication Systems","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124329151","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}

Initially the key concepts of an integrated IN / B-ISDN architecture are presented aiming at the provision of novel multirnedia features such as the coordination of different calls in a session as well as call / connection separation. The paper proposes alternative ways of producing IN service models from the prose description of the services. Consequently we examine the available options for distributing service logic in the various network nodes followed by a discussion on service data tables and the specification of rnessage flows across interfaces. Finally a mapping from a formal service specification in SDL towards a an actual service design is provided by means of a Service Creation and Simulation Environment. Throughout the paper two services are used for providing practical examples of the proposed methodology - a Video on Demand (VoD) service which is a true IN service and a Broadband Video Conference Service (B-VC) which is based on an existing implementation originally targeted for a TCP IP network platform.","PeriodicalId":178651,"journal":{"name":"The Fourth IEEE Workshop on High-Performance Communication Systems","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114021864","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}

One concern is the buffer memory requirement of credit FC, which is high when static, per-connection buffer allocation is used. The memory size can be reduced by dynamically sharing the buffer among the connections. We formulate and prove a new upper bound for the dynamically-shared buffer size, which applies when the downstream network guarantees that it will never throttle a connection down below a given minimum \"draining\" rate. This upper bound is inversely proportional to the minimum draining rate, and is independent of the number of connections. The minimum draining rate can be guaranteed by giving to the traffic arriving at a local area through long distance links priority over locally generated traffic in the use of a given fraction of the outgoing network capacity. In practical situations, the new upper bound can be made small, thus providing a new, additional method to reduce the buffer memory cost to a very small percentage of the link cost. Unlike other such methods, no link underutilization may occur and there is no rate ramp-up delay.","PeriodicalId":178651,"journal":{"name":"The Fourth IEEE Workshop on High-Performance Communication Systems","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115437954","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}
