Optical resilient packet ring (ORPR) buffer model and delay analysis

Abstract

A new Optical Resilient Packet Ring buffer model was introduced in this paper, end-to-end delay of packet in Optical Resilient Packet Ring was analyzed. The computing equation for end-to-end average delay of packet with different service priority was proposed,while fiber-delay-lines acting as transfer buffer at node.The relationship between delay and traffic, fiber delay lines unit length is analyzed via the equation.
