Virtual BUS: an easy-to-use environment for distributed resources

This paper discusses how a distributed environment providing effortless networking can be efficiently implemented in a network system. To formalize the distributed environment, we introduce the concept of “Virtual BUS”. It is similar to the concept of the computer system´s bus architecture. We define user behavior as accessing the resources in a network through his/her own bus. Based on this simple formalization, we discuss the key issues in implementing distributed environments to support different requirements for realizing the quality of service desired. We implement an experimental effortless networking environment based on the Virtual BUS concept and show that the concept realizes effortless networking while guaranteeing QoS
