We have devised a mechanism called law-governed interaction (LGI) for this purpose. LGI can be used to specify a wide range of policies to govern the interactions among the members of large and heterogeneous communities of agents dispersed throughout a distributed enterprise, and to enforce such policies in a decentralized and efficient manner. What concerns us in this paper is the fact that a typical enterprise is bound to be governed by a multitude of policies. Stich policies are likely to be interrelated in complex ways, forming an ensemble of policies that is to govern the enterprise as a whole. As a step toward organizing such an ensemble of policies, we introduce a hierarchical inter-policy relation called a superior/subordinate relation. This relation is intended to serve two distinct but related purposes: first, it helps to organize and classify a set of enterprise policies; second, it helps regulate the long-term evolution of the various policies that govern an enterprise. For this purpose, each policy in the hierarchy should circumscribe the authority and the structure of those policies that are subordinate to it, in some way analogous to the manner in which a constitution in American jurisprudence constrains the laws which are subordinate to it. Broadly speaking, the hierarchical structure of the ensemble of policies that govern a given enterprise should reflect the hierarchical structure of the enterprise itself.","PeriodicalId":370124,"journal":{"name":"Proceedings Third International Workshop on Policies for Distributed Systems and Networks","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127370018","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}

The design is based on distributed components and CORBA is used as a middleware for component interaction. The Diffserv policies are installed based on the role combination assigned to the network device interfaces and policy caching is used to improve the performance. The feasibility and performance of managing and deploying IntServ and Diffserv, policies for QoS management is demonstrated using Linux-based routers. The preliminary performance measurements show that the policy server response time is below 5 ms per request for 20 COPS-RSVP requests per second. COPS-PR processing takes more time compared to COPS-RSVP requests. It is found that the directory access could become a bottleneck in scaling the performance of the policy server and it can be improved substantially by employing appropriate policy caching mechanisms.","PeriodicalId":370124,"journal":{"name":"Proceedings Third International Workshop on Policies for Distributed Systems and Networks","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126393360","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}
