The stimulus to develop this architecture arises from an actual need to manage a cluster of active nodes, where it is often required to redeploy network assets and modify node connectivity. In our architecture, a remote front-end of the managing entity allows the operator to design new network topologies, to check the status of the nodes and to configure them. Moreover, the proposed framework allows to explore an active network, to monitor the active applications, to query each node and to install programmable traps. In order to take advantage of the active networks technology, we introduce active SNMP-like MIBs and agents, which are dynamic and programmable. The programmable management agents make tracing distributed applications a feasible task. We propose a general framework that can interoperate with any active execution environment. In this framework, both the manager and the monitor front-ends communicate with an active node (the Active Network Access Point) through the XML language. A gateway service performs the translation of the queries from XML to an active packet language and injects the code in the network. We demonstrate the implementation of an active network gateway for PLAN (Packet Language for Active Networks) in a forty active nodes testbed. Finally, we discuss an application of the active management architecture to detect the causes of network failures by tracing network events in time.","PeriodicalId":402782,"journal":{"name":"Proceedings of Fourth Annual International Workshop on Active Middleware Services","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124187105","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}

Significant differences in performance and qualitative attributes between wired and wireless networks necessitate adaptation and arbitration mechanisms in order to deliver group transport services. Janus provides a proxy mechanism to reconcile differences between the wired and wireless domains, incorporate synchronization algorithms to prevent delivery lags caused by high network variability, and anticipate and take appropriate actions when approaching (or when within) \"trouble spots\" or dead zones that are intrinsic to wireless networks. These adaptive mechanisms are implemented in software capable of executing on devices ranging from hand-helds to laptops to desktops, and manifested as libraries that provide group communication facilities at different levels of data delivery semantics. A discussion of unique challenges in hybrid wired and wireless networks, a description of the Janus active middleware architecture, and preliminary results and experiences are presented in this paper.","PeriodicalId":402782,"journal":{"name":"Proceedings of Fourth Annual International Workshop on Active Middleware Services","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123142075","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}

Service-discovery protocols, which enable software components to locate available software services and to adapt to changing system topology, provide one foundation for such dynamic behavior. Emerging discovery protocols specify alternative architectures and behaviors, which motivate a rigorous investigation of the properties underlying their designs. Here, we assess the ability of selected designs for service-discovery protocols to maintain consistency in a distributed system during severe message loss. We use an architecture description language, called Rapide, to model two different architectures (two-party and three-party) and two different consistency-maintenance mechanisms (polling and notification). We use our models to investigate performance differences among combinations of architecture and consistency-maintenance mechanism as message-loss rate increases. We measure system performance along three dimensions: (1) update responsiveness (how much latency is required to propagate changes); (2) update effectiveness (what is the probability that a node receives a change?), and (3) update efficiency (how many messages must be sent to propagate a change throughout the topology?).","PeriodicalId":402782,"journal":{"name":"Proceedings of Fourth Annual International Workshop on Active Middleware Services","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127401034","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}
