Most data concerning the topology of complex networks are the result of mapping projects which bear intrinsic limitations and cannot give access to complete, unbiased datasets. A particularly interesting case is represented by the physical Internet. Router-level Internet mapping projects generally consist of sampling the network from a limited set of sources by using traceroute probes. This met...

Recently the Internet has witnessed the emergence of content distribution networks (CDNs). In this paper we study the problem of optimally replicating objects in CDN servers. In our model, each Internet Autonomous System (AS) is a node with nite storage capacity for replicating objects. The optimization problem is to replicate objects so that when clients fetch objects from the nearest CDN serv...

In the first phase, questionnaire, interview, and focus group were used as tools to invest...

Internet technology has become an important channel for accessing information and solving problems. However, researchers have indicated that most students lack effective strategies for searching for information on the Internet, and hence their learning performance is not as good as could be expected. To address this issue, in this study, a five-phase learning cycle approach is proposed to condu...

We describe the ingredients of an intelligent agent (a broker) for connguration and execution of knowledge systems for customer requests. The knowledge systems are conngured from reusable problem-solving methods that reside in digital libraries on the Internet. The approach followed amounts to solving two subproblems: (i) the conngura-tion problem which implies that we have to reason about prob...

Traditional problem determination techniques rely on static dependency models that are difficult to generate accurately in today’s large, distributed, and dynamic application environments such as e-commerce systems. In this paper, we present a dynamic analysis methodology that automates problem determination in these environments by 1) coarse-grained tagging of numerous real client requests as ...
