在已分配波长信道预约低优先级但未到达本次节点，重发该数据突发更改的信息，等待数据缓冲延迟实现中的关键节点的数据已经预留波长。利用光缓存机制，光分组进入缓存前需确定好延迟时间，利用光纤分段式共享机制，优化公平和竞争机制，获取最短的光分组平均延时参数。通过模拟实验，分析找出能够减少适合气象网络光纤延迟的机制。确定优先级高低机制，利用调整光纤网络波长信道预约向高级别调用可以减少数据丢包和网络延迟。%In allocated wavelength channel reservation low priority but not arriving at the node,the data delayed has changed the retrans-mission of BCP information,that is waiting for the data delayed cache delay adjustments to achieve the wavelength channels on each node data delayed has an appointment at the core. Use light cache mechanism, determine a good delay time before optical packet into the cache. Apply mechanism of sectional sharing by using optical fiber,optimization of fair and competitive mechanism,obtaining the shortest optical packet average delay parameters. The simulation results show that the test analyzes and finds suitable mechanism which can reduce the weather network optical fiber delay. The conclusion is to determine the priority level adjustment mechanism,using the optical fiber network wavelength channel reservation to high level calls can be delayed to reduce data packet loss and network delay.
