A system and method for implementing collision resolution scheduling in satellite optical burst switch

Abstract

A system and method for implementing collision resolution scheduling of satellite optical burst switch. According to the topology of space-based broadband transmission backbone network and the statusof each switching node, through the scheduling method of network resources pre-allocation, at that boundary of the space-based broadband transmission backbone network, the data to be transmitted and exchanged to the space-based broadband transmission backbone network is controlled, the switching time and the forwarding path of each optical burst data entering into the space-based broadband transmission backbone network are planned in advance, and the collision resolution scheduling of the optical burst data exchange of the space-based broadband transmission backbone network is realized. The optical burst data of the space-based broadband transmission backbone network is generated by the electric domain. After completing the electro-optical conversion at the edge node of the backbone network, the optical burst data enters the backbone network for optical burst exchange. After reaching the destination edge node, the optical burst data is converted, and then the data is sent to the processing terminal to complete the data routing exchange process. Through pre-planning and scheduling, the system can resolve the collision of satellite optical burst switch by using network resources.

Description

technical field [0001] The invention relates to a system and method for realizing optical burst conflict resolution applied to a satellite backbone optical switching network, and belongs to the field of communication. Background technique [0002] With the further improvement of the switching capacity of the satellite network, the original on-board power processing method will not be able to meet the requirements of large-bandwidth and high-speed data transmission and exchange in the future, and the use of optical signals for on-board data transmission and exchange will become an important part of future satellite large-capacity data transmission. Network technology development direction. Due to the large data traffic of the satellite backbone network and the limited optical data on-board storage technology, it is impossible to avoid optical data exchange conflicts at the optical switching nodes of the backbone network by means of store and forward. Conflict issues. [000...

AI Technical Summary

Problems solved by technology

[0003] The current system does not involve the implementation method of satellite optical burst switching data conflict resolution. The ground optical burst switching scheduling method mainly uses optical buffering or single node scheduling to control the transmission of optical data, and does not mention the use of the entire switching network.
