The existing available bandwidth measurement techniques aimed only at knowing available bandwidth of the bottleneck part on the path and most of them do not specify where is the bottleneck, and they do not measure available bandwidth of each part of the path separately. Also, they can not measure available bandwidth of multiple parts on the path. In this paper, we propose a simultaneous measurement method of available bandwidth of multiple parts on an end-to-end network path. The proposed method estimates the available bandwidth based on changes in packet sending and arrival intervals under the situation where intermediate routers on the path can record time on incoming packets as a timestamps. We present extensive simulation results of the proposed method and confirm that it can accurately measure available bandwidth of each part on the path even when the available bandwidth of the sender-side network is smaller than that of the receiver-side network.","PeriodicalId":394442,"journal":{"name":"2012 IEEE International Workshop Technical Committee on Communications Quality and Reliability (CQR)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132485249","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}

It measures how often a long service outage occurs, which is important because long service outages can seriously affect customers. The method currently used is problematic because the evaluation time increases exponentially with the telecommunications network size. A recently proposed approximation method by Watanabe et al. is highly accurate but its evaluation time also increases exponentially. Other known heuristic approximations are applicable only to cases in which the telecommunications network can be represented by series and/or parallel systems. The method proposed here overcomes these limitations. It is based on a simple equation that includes the frequency of long service outage and the frequency of failure. This equation gives both the upper and lower bounds of the value obtained with Watanabe's method, where these bounds are very close to each other, under the reasonable assumption that each element of a telecommunications networks is highly reliable. Numerical examples show that this method can be used to more quickly and more accurately evaluate the frequency of service outages for a realistically large network.","PeriodicalId":394442,"journal":{"name":"2012 IEEE International Workshop Technical Committee on Communications Quality and Reliability (CQR)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130257894","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}

While the 3×3 node implementation allows for speedup and much higher throughput performance, the traffic load must be kept medium to maintain the reasonably low packet drop rate. The addition of QoS capability within the routing node allows the network to support multiple classes of traffic, and selectively drop the packets based on their priority. In the simulation study, two priority traffics are considered with proper modification of routing node logic. The results show that with slight increase in routing decision complexity, the high priority traffic can be guaranteed much better performance in packet drop rate. The average latency performance is also slightly improved for high priority traffic in comparison to low priority traffic. The low priority traffic encounters slightly more packet drop rate as a result, and this becomes more significant as the network reaches performance saturation. The proposed QoS implementation allows for overall reasonable network performance as the non-QoS network, and it provides much better performance for higher priority traffic for practical applications. Since the low priority traffic encounters more sacrifice at heavy traffic loads, overall traffic is still desired to be controlled at a reasonable level.","PeriodicalId":394442,"journal":{"name":"2012 IEEE International Workshop Technical Committee on Communications Quality and Reliability (CQR)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121188257","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}
