Abstract

The present invention relates to a satellite optical burst switching conflict resolution scheduling implementation system and method, according to the network topology of the space-based broadband transmission backbone network and the status of each switching node, through the scheduling mode of pre-allocation of network resources, in the space-based broadband transmission backbone network The boundary controls the data that will enter the space-based broadband transmission backbone network for transmission and exchange, pre-plans the exchange time and forwarding path of each optical burst data entering the space-based broadband transmission backbone network, and realizes the optical burst data exchange of the space-based broadband transmission backbone network conflict resolution scheduling. The optical burst data of the space-based broadband transmission backbone network is generated by the electrical domain. After the electrical-optical conversion is completed at the edge node of the backbone network, it enters the backbone network for optical burst exchange. After reaching the destination edge node, the optical-electrical conversion is completed, and then the data is sent to the processing terminal. , to complete the data routing exchange process. The system utilizes network resources to resolve conflicts in satellite optical burst switching through pre-planning and scheduling.

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...
