AI Technical Summary
Technical Problem
In industrial control systems, transmission failures of control data packets can prevent the upper layer of the controlled entity from receiving them on time, leading to erroneous behavior. Existing technologies are unable to effectively reduce this situation.
Method used
The access layer handles data packet delivery based on the cache status, including delivering normally arriving data packets, timed-out data packets, or not delivering data packets, and sends notification information when necessary to reduce downtime caused by upper-layer timer timeouts.
Benefits of technology
By optimizing the data packet delivery strategy, the risk of erroneous execution and downtime of the controlled party is reduced, thereby improving the stability and reliability of the system.

Abstract
一种数据递交方法及装置，该方法包括：确定接入层向上层递交第一数据包的递交时刻；根据接入层的缓存在第一数据包的递交时刻存储数据包的情况，处理接入层向上层的数据包递交。例如，处理接入层向上层的数据包递交可包括接入层向上层递交正常到达的第一数据包，或者，超时的第二数据包，或者，不向报数据包。接收方根据接入层的缓存中数据包的存储情况，向上层递交数据包，可在减少上层定时器超时引起的宕机的情况下，最大限度的减少被控制方的行为错误。
