Adaptive resource management in active network nodes

Resource management in active network nodes is challenging because more types and amount of resources are needed compared with traditional networks, and the consumption of different types of resources is not equally balanced. Hence, it is possible and important to consider the relationship between different types of resources, needed by an application. Adaptation of applications resource usages in network nodes enables the applications to react promptly to the resource status in the network nodes and therefore offers a better performance guarantee and more flexibility to the applications. This paper studies the resource management in active network nodes considering the relationship among different types of resources. The resource vectors (RVs) are introduced to describe the resource requirements of applications and their adaptation capabilities. And an adaptive resource management mechanism based on RV is proposed and the implementation of it in an active node is given.
