As Internet of Things advances, various smart objects and services permeate in our living environment. Due to their dynamic join/leave behaviors, service discovery protocols (SDPs) have been proposed. As new SDPs are introduced and legacy SDPs evolve, the incompatible islands of smart objects inevitably arise. To solve this issue, many research works are presented, but they cannot accommodate a new...
To reduce the work load of network administrators, e.g., fault detection/recovery, performance analysis and security maintenance etc., knowledge-based intelligent support system for network administrator based on active information resource (AIR-NMS) have been proposed. In this paper, we describe some design pattern and some implemented examples of activated information resource (AIR) on network administration...
As a solution to Single Sign-On (SSO), OpenID can simplify users' operation process and reduce resource provider's overhead. Its application in the websites is becoming popular and the multi-level security of OpenID has also become a topic of concern. First the basic OpenID infrastructure is introduced, including its components, hierarchy and other key issues. A multi-level security framework for...
We present the design and implementation of ENDEAVOUR - a framework for integrated end-to-end disaster recovery (DR) planning. Unlike existing research that provides DR planning within a single layer of the IT stack (e.g. storage controller based replication), ENDEAVOUR can choose technologies and composition of technologies across multiple layers like virtual machines, databases and storage controllers...
Large-scale data grid systems (LDGS) facilitate collaborative sharing of large collections (Petabytes and 100s of millions of objects) containing files, databases and data streams that are geographically distributed across heterogeneous resources and multiple administrative domains. LDGS provide a "universal view" of the distributed data, resources, users and methods and hide the idiosyncrasies...
