Embodiment 1
[0035] Embodiment 1 of the present invention provides a Capwap tunnel connection control method, the step flow of the method can be as follows figure 2 shown, including:
[0036] Step 101. Determine whether a packet retransmission is successful.
[0037] In this embodiment, when the access controller AC performs a round of Echo Request message retransmission on the control channel of the Capwap tunnel, it can adjust the maximum number of retransmissions respectively according to the success or failure of a message retransmission, so , in this step, it can be determined whether a packet retransmission is successful.
[0038] Specifically, if a message is retransmitted successfully, it can be understood that the AC dispatches an Echo Response message after retransmitting the message. If the packet retransmission failed this time, it can be understood that the AC did not schedule the Echo Response packet after the packet retransmission this time.
[0039] This step specifical...
Embodiment 2
[0063]Preferably, the first threshold value and the second threshold value involved in Embodiment 1 can be set as dynamically changing values according to the current maximum number of retransmissions, and each time the maximum number of retransmissions is increased or decreased The magnitude of can also be set, for example, set according to the current maximum number of retransmissions. For example, the first threshold value can be set as a value obtained by rounding up two-thirds of the current maximum number of retransmissions (for example, the current maximum number of retransmissions is 5, and two-thirds of the current maximum number of retransmissions is upwards When the value obtained by rounding is 4), the increased maximum retransmission times can be the value obtained by rounding up to four-thirds of the current maximum retransmission times (for example, the current maximum retransmission times are 5, and the current maximum retransmission times Four-thirds of the ...
Embodiment 3
[0072] Embodiment 3 of the present invention provides a Capwap tunnel connection control method, the step flow of the method can be as follows image 3 shown, including:
[0073] Step 201, initialize the maximum number of retransmissions.
[0074] In this embodiment, the maximum number of retransmissions is 5 times stipulated in the existing protocol as an example for illustration.
[0075] Step 202, determine that the Capwap tunnel enters the normal operation state.
[0076] Step 203, determine whether a round of packet retransmission occurs.
[0077] For each round of packet retransmission, the number of packet retransmissions (which can be represented by Count) can be initialized, and the initialization value can be 0, that is, N-1 indicates that the number of packet retransmissions is N. It can be understood that every time a packet is retransmitted, the number of packet retransmissions is increased by 1.
[0078] And in this embodiment, if the normal operation time of...
