Abstract

The invention discloses a weight ratio-based burst service bandwidth dynamic allocation method and system, and relates to the field of aerospace. The method comprises the following steps: polling thestate information of each preset node in sudden service bandwidth allocation insensitive to time delay, calculating the bandwidth allocation weight of each preset node according to the obtained information, and calculating the minimum guaranteed bandwidth of the preset node according to the bandwidth allocation weight; and performing bandwidth allocation according to the request bandwidth in combination with the guaranteed bandwidth to obtain an updated data transmission state and an updated request bandwidth of the preset node, and dynamically adjusting and correcting the bandwidth allocationof each preset node according to the updated data before the next round of transmission. Bandwidth transmission of a strong aging service, a time delay sensitive service and a burst service is effectively ensured, the reliability of data transmission is enhanced, the network bandwidth utilization rate is improved, and the network throughput is improved.

Description

technical field [0001] The invention relates to the aerospace field, in particular to a method and system for dynamically allocating burst service bandwidth based on weight ratio. Background technique [0002] With the continuous expansion of the scale of application tasks in the aerospace field, the types of payloads mounted on large aerospace information networks are increasing, the control is becoming more and more complex, the amount of information transmitted is increasing, and the transmission rate is increasing. High, the above characteristics put forward higher requirements for the real-time performance, data transmission bandwidth, data processing capability and reliability of the highly reliable application information network. [0003] FC-AE-1553 (Fibre-Channel Avionics Environment-Upper Layer Protocol: FC-AE-1553) network is considered to be a One of the protocols to meet the needs of future aerospace missions and become the preferred network for future aerospac...
