Compared to existing techniques, the approach introduces a very low transmission and computational overhead, allows a higher cell-loss rate, and produces a less image degradation. In this approach, the preprocessor rearranges the content of image files, and then packs these fixed image files into ATM cells for transmission. The post-processor unpacks the cells, restores the original content orders, and if part of the data has been discarded, performs data recovery to reconstruct imprecise image files as close to their original versions as possible. By marking an appropriate number of cells, a user can specify an acceptable lower bound on the quality of the image that is delivered at the destination. This mates it possible to control and know which part of the image data can be discarded. The experimental results show that by using the proposed approach, the quality of the received/recovered images decreases more slowly than the proportional increase in network congestion.","PeriodicalId":286255,"journal":{"name":"Proceedings of 22nd Annual Conference on Local Computer Networks","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134574915","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}

Of particular interest are the end-to-end latencies obtainable using ATM networks to transfer time critical data. Latencies obtained using classical IP over ATM and raw ATM using the Fore ATM API are compared to performance of traditional TCP/IP on equivalent FDDI networks. It is shown that at OC-3, in its simplest configuration of back to back nodes, classical IP over ATM latencies are greater than those obtained using FDDI, particularly at small message sizes. However, the results show that IP over ATM via ATM switches can exhibit better performance than FDDI switches or routers, due to the optimization of the ATM switch for fixed size cells. Thus, these benchmarks confirm that ATM provides a good foundation for building high performance IP internetworks. A discussion of trade-offs associated with using FDDI versus ATM for mission critical, real time data transfer applications is also included.","PeriodicalId":286255,"journal":{"name":"Proceedings of 22nd Annual Conference on Local Computer Networks","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132371541","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}

However, if we increase the data rate from 10 Mb/s Ethernet to 100 Mb/s Fast Ethernet, shared access via CSMA/CD becomes less efficient because of the resulting increase in size of the collision fragments. For example, in a typical star wired single repeater network with a diameter of 200 meters, upgrading from 10BASE-T to 100BASE-T increases the round trip delay from about 100 bit times to almost 500 bit times. Moreover, a further upgrade to 1000 Mb/s Gigabit Ethernet would increase the round trip delay to about 4000 bit times. We introduce a simple change to the handling of incoming signals at the repeater ports known as collision truncation, and show that it reduces the average duration of a collision by more than 50% for networks with large round trip delays. For the standard BEB Ethernet protocol operating at moderate load, collision truncation reduces the mean end to end network delay by more than 25% for 100 Mb/s Fast Ethernet and by more than 50% for 1000 Mb/s Gigabit Ethernet. For BLAM, collision truncation increases the maximum throughput by more than 10%, and reduces the mean end to end delay substantially under high load. Collision truncation requires no changes to the host network adapters, and its use is completely transparent to the hosts. The only behavioral change that is visible to the attached hosts is the illusion that the network diameter appears to have been reduced. The relative cost of adding collision truncation to a repeater is very small compared to upgrading to a frame level device, such as a bridge.","PeriodicalId":286255,"journal":{"name":"Proceedings of 22nd Annual Conference on Local Computer Networks","volume":"34 25","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113941832","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}
