Abstract

Protection and restoration are essential mechanisms for guaranteeing more reliable traffic delivery services. But it is not easy to apply existing mechanisms to optical burst switching (OBS) networks due to its one-way reservation signaling and the statistical burst multiplexing. Thus, to achieve the high transmission performance and reliability simultaneously, unique properties of OBS must be considered in the design of protection scheme. In this paper, we introduce a new 1:1 link-based OBS protection with several control messages. It minimizes burst losses by deflecting bursts until the source edge router arbitrates a working burst path to a backup path when a link failure occurs. Based on this, we propose a genuine dynamic resource sharing (DRS) protection algorithm. It optimizes the number of provisioned protection wavelengths adaptively based on the traffic load as well as the quality of service (QoS) requirements of bursts in near real-time. In addition, DRS can be used as the temporary short-term contention resolution method. The simulation results verify that the proposed schemes improve the network resource sharing and backup link’s channel utilization while guaranteeing the targeted protection reliability and QoS requirements of class bursts.
