between the nodes in these networks is congruent with the underlying IP-level topology. Similarly, in the case of replicated web content, client nodes could use topological information in selecting one of multiple available servers. For such applications, one need not find the optimal solution in order

Abstract: In DNS zone delegation, the NS resource records of the delegated domain appear in both the parent and child zones, which complicates the domain name resolution procedure especially for server selection. In this paper, we investigate the recursive resolution mechanism for the delegated

We evaluate server selection methods in a Web environment, modeling a digital library which makes use of existing Web search servers rather than building its own index. The evaluation framework portrays the Web realistically in several ways. Its search servers index real Web documents

this paper, we propose the server selection policy using RTT information measured at an active router. By means of the server selection based on this RTT, the selection of the server considering not only the server load but also network congestion and distance from the active router to the server

Abstract. Previous evaluations of server selection methods for federated search have either used metrics which are unconnected with user satisfaction, or have not been able to account for confounding factors due to other search components. We propose a new framework for evaluating federated search

Widespread replication of information can ameliorate the problem of server overloading but raises the allied question of server selection. Clients may be assigned to a replica in a static manner or they may choose among replicas based on client-initiated measurements. The latter technique, called

Many service providers prepare multiple servers to cope with over loading. In such cases, the problem is how to select the best server. Existing mechanisms impose user extra e#ort or have less #exibility. In this paper, we describes #exible and wide applicable server selection mechanism. We add
