Network technology for accelerating optical outburst exchange resource subscription using wireless optical communication

Abstract

Preengagement region is designed and constructed around tangent method. Bias time is setup by using bias time sub module. Radio laser signal BHP is sent to boundary chain of radio laser comm. from boundary node interface. Then, BHP is passed and processed through following steps: being received and processed by radio light core node; passing through multicast of core link of radio laser comm. to core node interface of boundary Burst route process; using core node processes BHP, and exchanges information at ports between neighboring core nodes etc. to establishes connection rapidly. The method speeds up operation for preengaging resources to reengagement region in high quality. Comparing with switching network of light outburst in pure fiber, the invention reduces bias time, and time of using resources by BHP.

Description

technical field [0001] The present invention belongs to the field of optical communication technology and its implementation, and its implementation relates to optical fiber communication and wireless laser communication, and relates to the reduction of optical burst switching (Optical Burst Switching, OBS) one-way resource reservation through wireless optical core nodes and related network elements. It takes time and other processing costs, involves the reservation domain, and involves high resource utilization and high service quality brought about by the integrated operation of the optical fiber communication network and the wireless laser communication network. Background technique [0002] Dense Wavelength Division Multiplexing (DWDM) optical transmission provides unprecedented huge bandwidth. With the mature application of DWDM technology and corresponding equipment, in order to overcome the bottleneck of electrical switching capacity, reduce network costs, and improve ...

AI Technical Summary

Problems solved by technology

[0010] In a pure optical fiber OBS network, the required minimum bias time is Σ j = 1 T H d j , Corresponding processing costs, etc., have brought delay problems; the network resources available for BHP and its corresponding burst data packets are limited, especially at the same time, each BHP that reserves resources at a core node randomly comes from each edge node, and the competition ( contention) deteriorates the network performance and makes the resource usage efficiency extremely low. In this regard, the existing solutions in the pure optical fiber OBS network technology have limited performance and may further aggravate the delay problem

When the network provides services, resource utilization efficiency and quality of service (QoS) are not ideal, which greatly reduces the rationality of the OBS network mechanism and the application prospects of the OBS network, and must be properly resolved
