This requires faster hello exchanges (unless one relies on link level detection which is not always possible), fast flooding, and more frequent shortest-path-first calculations. However, through analysis and simulation we show that this compromises the scalability and stability of the network. This is mainly because hello packets received at a router are indistinguishable from other packets and may experience long queueing delays during a sudden burst of many LSA (link-state advertisement) updates and cause the associated link to be declared down. At a later instant the link would recover. Both the failure and recovery generate fresh LSA, in effect developing a feedback loop to sustain the LSA storm. We suggest that hello and potentially some other IGP packets, such as acknowledgments, be marked explicitly so that they may be distinguished and queued separately from other IGP and data packets at the line rate and provided prioritized treatment. This allows significant reduction in IGP convergence time while maintaining network stability.","PeriodicalId":213526,"journal":{"name":"Proceedings LCN 2001. 26th Annual IEEE Conference on Local Computer Networks","volume":"520 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123047142","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}

Though on-demand routing approaches have been shown to perform well, they generally lack the support for quality-of-service (QoS) with respect to data transmission. In order to select a subset of end-to-end paths to provide increased stability and reliability of routes, a new QoS metric, end-to-end reliability, is defined and emphasized. We present a distributed multi-path dynamic source routing protocol (MP-DSR)for wireless ad-hoc networks to improve QoS support with respect to end-to-end reliability. Our protocol forwards outgoing packets along multiple paths that are subject to a particular end-to-end reliability requirement. A simulation study is performed to demonstrate the effectiveness of our proposed protocol, particularly the fact that MP-DSR achieves a higher rate of successful packet delivery than existing best-effort ad-hoc routing protocols, such as the dynamic source routing (DSR).","PeriodicalId":213526,"journal":{"name":"Proceedings LCN 2001. 26th Annual IEEE Conference on Local Computer Networks","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124227162","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}

Certain fundamental services are highly desirable to achieve these twin goals of network-based cluster system analysis and management. Among these services is the ability to detect network and node failures and the capability to efficiently determine computer and network load levels. Furthermore, the ability to allow for the distribution of administrative directives is also integral to the goal of cluster management. This paper presents a scalable approach to providing these vital support capabilities for distributed computing integrated into a cluster management system. Previous approaches to cluster management have suffered from problems of scalability and the inability to properly support heterogeneous systems in a non-proprietary fashion. This cluster management system employs gossip techniques to address the problem of scalability in network-based system management. The results of two case studies show that the cluster management system is scalable and has little adverse impact on the performance of sequential and parallel applications running on the managed system.","PeriodicalId":213526,"journal":{"name":"Proceedings LCN 2001. 26th Annual IEEE Conference on Local Computer Networks","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123217114","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}
