When rekeying, only one message needs to be generated, and the message size is a constant. Especially when the group size is large, our framework largely reduces the traffic in the network. Two solutions are given to carry out this framework, which are closed curve solution (CCS) and perpendicular space solution (PSS), respectively. One is based on a geometric approach and the other on a linear algebraic approach. Our framework is also compatible to other group communication protocols.","PeriodicalId":213526,"journal":{"name":"Proceedings LCN 2001. 26th Annual IEEE Conference on Local Computer Networks","volume":"59 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":"130498703","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, setting up static service level agreements (SLA) between different Internet service provider domains lacks flexibility and may reduce quality of service as resource reservations cannot be adapted to the actual traffic. With the introduction of bandwidth brokers, a significant step towards a completely dynamic Differentiated Services environment has been made. Bandwidth brokers negotiate and automatically set up SLA according to network load and provider policies. Nevertheless, this automatic set-up may fail if there are bottlenecks in the network caused by physical limitations or policy issues and may lead to congestion. In this paper, we propose a scalable mechanism to handle these congestion situations, that uses four phases each solving a different level of congestion. Our mechanism does not need any destination information thus making it applicable for the majority of Internet applications.","PeriodicalId":213526,"journal":{"name":"Proceedings LCN 2001. 26th Annual IEEE Conference on Local Computer Networks","volume":"83 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":"132850363","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}

We assume that the network runs on-demand routing and carrier sense-based medium access protocols. The technique, however, is general and should apply to other types of protocols. We develop a tool that determines the network capacity given session-level traffic and node mobility traces. We compare the network capacity so determined with the actual network utilization from output statistics generated by a comprehensive simulator. It is observed that network capacity increases with node mobility; but the routing and medium access protocols fail to take advantage of the increased capacity. Even with high loads, a significant portion of the network capacity is not utilized, while the routing performance remains poor. This study indicates that there is a significant scope for designing aggressive routing protocols that utilize the network capacity better to improve routing performance.","PeriodicalId":213526,"journal":{"name":"Proceedings LCN 2001. 26th Annual IEEE Conference on Local Computer Networks","volume":"56 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":"128251003","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}

Providing bandwidth and connectivity on demand has risen to be an important goal for service providers. To realize this, signaling in the optical network seems to be a critical component. Provisioning involves establishing a circuit from one client end system to another, through the optical backbone. With this general notion, this paper discusses in brief the role of signaling in all-optical networks, which employ DWDM for lower layer transport. The architectural choices pertaining to lightpath services are outlined. Signaling procedures for ensuring dynamic end-to-end lightpath setup have also been presented. Path provisioning comprises a string of operations like service and neighbor discovery, route computation, signaling requests, and path setup. This paper tries to summarize the various strategies, designed for each step, for use in the all-optical networks.","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":"115325300","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, existing routing protocols for such networks neither scale nor function on the Internet. Therefore, a solution is required that provides a gateway between the ad hoc network and the Internet. In this paper, we propose a protocol-independent Internet gateway for ad hoc networks, the Cluster Gateway (CG). The proposed Cluster Gateway (CG) provides Internet access by acting as both a service access point and a Mobile IP foreign agent for ad hoc networks. In this paper, we describe the requirements for supporting the CG in any ad hoc routing protocol, the messages sent in order to provide CG support, and several optional enhancements for the CG. Finally, we briefly describe an implementation of the CG over an existing ad hoc routing protocol.","PeriodicalId":213526,"journal":{"name":"Proceedings LCN 2001. 26th Annual IEEE Conference on Local Computer Networks","volume":"20 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":"114670317","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}
