Implement method of resource reservation protocol with multi-services convergence transmission for optical burst switching networks

摘要

An implement method of reservation protocol with multi-services convergence transmission for OBS networks differentially processes the synchronous service flow and the asynchronous service flow, and assembles multiple different types service data into different data burst (DB) by generalized optical-burst paradigm. It functionally expands burst control packet (BCP) and classifies the BCP into two categories: routine burst control packet (R-BCP) and synchronous trace burst control packet (T-BCP). Then it can differentially reserve wavelength channel resource and preempt resource to try to keep the transmission features of synchronous service such as period, low delay jitter and low dropping probability on the base of ensuring the basic QoS requirements of various kinds of service, and realize that a single OBS network efficiently provides asynchronous service and synchronous service.
