¿µ¹®³»¿ë¿ä¾à Currently, there exist various network testbed infrastructures for developing and experimenting innovative network technologies. The testbeds are managed by their own control frameworks and administered by local policy, such as authentication and authorization of users, resource allocation policy, and so on. So, it is hard to build large scale testbeds in the global scale. It is known that federation can provide large scale, diverse, and realistic network testing environments. Resources must be able to appear and be useful on more than one testbed in order to increase utilization and resource diversity rather than exclusive use. This document investigates federation scenarios and problems which will occur during federating multiple heterogeneous testbeds. The problems include considerations for authentication and authorization mechanism, control framework, description and management of testbed components. Also, several requirements to mitigate the identified problems are discussed.
