Abstract: For some real-time applications, it is necessary to provide a fast switch over to the backup connection whenever the primary connection fails. With the increase in reliability of network link, it is more cost effective if the backup resources are shared among a number of users. However, the sharing of backup resources must be controlled to ensure the users are provided with high availability of the backup connections. In this paper, we derive a set of equations for the determination of the availability of a shared backup channel, develop a backup provision strategy based on the channel availability, and we then evaluate the effectiveness of the proposed controlled shared backup strategy.
