The application discloses a large file cross-unit transmission method based on a business cooperation scene, relates to the technical field of cross-organization
data transmission and
resource scheduling, and takes a
business context as a core to map an
event type, an emergency level and an SLA deadline time into a calculable priority, and is linked with real-time
network measurement results, so that scheduling no longer stays in static file attributes, but can instantly improve the service share of a key request according to events such as out-of-stock early warning and promotion start, thereby reducing the probability that a high-emergency task is blocked by regular transmission. By introducing unit-level quotas, admission and interruptible
preemption on the side of a
bottleneck link, long-term occupation caused by first-come-first-served is avoided, basic fairness between different units is ensured, and bandwidth can be quickly transferred to more urgent flows at a business peak moment. Weighted round-robin weights are dynamically updated according to the emergency degree, the SLA urgency degree and the quota surplus degree,
hysteresis and minimum interval control are superimposed, and the agility of scheduling is improved.
