Scenarios are frequently used within techniques for planning and designing systems. They are an especially helpful means of visualizing and understanding the incorporation of new systems within systems of systems. If used as the basis for decisions about candidate designs, then it is important that such decisions can be rationalized and quantitative assessment is particularly important. In this paper,...
Autonomic network management is viewed as the capability of network entities to self-government, which frees IT professionals from time-consuming and tedious configuration tasks. Hence, IT professionals can focus on high level management (business goals, for example). In this paper, we propose an approach of agent-based architecture for autonomic networking on the basis of Motorola's FOCALE architecture...
The paper proposes an architecture for heterogeneous network platform based on adaptation layer according to service capability requirements and characteristics of modern service industry. In order to shield the diversity of heterogeneous networks to provide open interfaces in the adaptation layer, an abstract method of service capability is proposed to get a set of SCF components and sub-platforms...
The vision of service-oriented computing is one of loosely coupled services that create agile applications to encapsulate business objectives and processes. The potential of services to form complex systems of systems, with emergent behaviour, necessitates the need to understand how we can we develop sufficient confidence in their qualities. In this paper we argue that successful development and evolution...
The theory of service oriented architecture (SOA) provides an idea to achieve application integration and on-demand services provision. But at the same time, its loose coupling structure brings great challenges to achieve effective service management. This paper analyzes the characteristics of SOA service deployment structure, and then proposes a novel SOA-oriented federate SLA management architecture...
Network enabled capability (NEC) is the U.K. Ministry of Defencepsilas response to the quickly changing conflict environment in which its forces must operate. In NEC, systems need to be integrated in context, to assist in human activity and provide dependable inter-operation. In order to provide reliable and sustainable military capability, fast paced changes must be conducted without halting the...
Traditional enterprise application integration (EAI) is essentially a "peer to peer" methodology which has many defects such as brittle, expensive, and impossible to maintain. The EAI implement with global workflow technologies is cheap and convenient. By study on environment and stratagem of enterprises, this paper establishes a solution of the EAI based on global workflow technologies...
Small-world phenomenon has been observed in existing peer-to-peer (P2P) networks, such as Gnutella and Freenet. Due to the similarity of P2P networks to social networks, the previous small-world model proposed by Duncan Watts can be adopted in the design of P2P networks: each node is connected to some neighbouring nodes, and a group of nodes keep a small number of long links to randomly chosen distant...
