Abstract

Scalable and reliable experiment support software needs to be developed to enable construction of large-scale experiment environments and experiments on the environment. The number of management servers in an experiment environment is generally less than the number of experiment nodes. This creates one-to-many communication when transferring data such as OS disk images. Recent experiment support software utilizes unicast communication for such types of data transfer, but this decreases the operational reliability of the software due to traffic congestion. To address this issue and increase reliability we propose the use of multicast communication. This paper investigates the requirements of reliable multicast for centralized testbeds using analysis and different considerations.
