The effect of the time delay of detection.
In order to be further described to above-mentioned scheme shown in FIG. 1, referring to FIG. 2, it illustrates another realities of the present invention
The method flow diagram of the heartbeat message sending method of example offer is provided.The heartbeat message sending method can be used in client.It should
Heartbeat message sending method may include:
In step 202, with T1/ 3 send N number of heartbeat message, T to server for the period1For client negotiation time-out when
Between.
Client negotiates time-out time using one third and sends heartbeat to server as the period when connecting with server
Message, also referred to as Ping message, if the network between client and server is unobstructed, server smoothly receives Ping report
Text can then return to a Pong message to client, identical information be carried in the Ping message and Pong message, if client
The Pong message for receiving client end response in the predetermined time after Ping message is being sent, then is confirming the connection with server
Normally.
In embodiments of the present invention, the Pong message that the Ping message and server that user end to server is sent return
In can only carry type of message, system time when message ID and client send Ping message；The Ping successively sent
The message ID carried in message can be incremented by successively.
In step 204, for each of N number of heartbeat message heartbeat message, when receiving the heartbeat message pair
When the response message answered, the system time t for including in the response message is obtained1And response message terminal when being received
System time t2。
When client receives a Pong message, it can extract and carry in the Pong message, client is sent pair
System time when the Ping message answered.Client also obtains system time when receiving the Pong message simultaneously.
In step 206, network delay δ=t of the heartbeat message is determined2-t1。
The client that client will acquire sends the system time Pong report corresponding with receiving when Ping message
The time interval between system time when literary is retrieved as the network delay of the Ping message.
In a step 208, the network delay δ of the heartbeat message is added into it is pre-set, length be N annular team
Column.
It is N number of circle queue that a length is preset in client, if client obtains the network of a Ping message
Delay, and the circle queue state is less than, then is added into the annular team for the network delay of the Ping message as an element
In column.
Specifically, network delay as shown in Figure 3, which obtains and negotiate time-out time, updates schematic diagram, wherein client with
T1/ 3 send Ping message to server for the period, when server receives Ping message every time, i.e., return to one to client
Corresponding Pong message, sending Ping message to the time received corresponding Pong message from client is that the Ping is reported
Network delay δ in text.In Fig. 3, circle queue length is fixed as 8, each network delay δ that client will acquire1、δ2、
δ3…δ8It is added into circle queue.
In step 210, according to the network delay of N number of heartbeat message and the negotiation time-out time T of the client1Really
Fixed new negotiation time-out time T2。
Specifically, client can determine new negotiation time-out time according to following three mode:
1) when the circle queue has been expired, the average value of N number of network delay in the circle queue is obtained；It is N number of to detect this
Whether the average value of network delay is greater than x*T1, x > 0；If the average value that testing result is N number of network delay is greater than x*T1, then
Determine T2=(1+X) T1；X > 0.
By taking Fig. 3 as an example, when being added into 8 elements in circle queue, client obtains each network in circle queue
Delay, calculates its average value, and compare the average value and T1Size relation between the 10% of/3, if the average value is greater than T1/3
10%, then the network delay of the Ping message sent before explanation is bigger than normal, at this point it is possible to which new negotiation time-out time is determined
For T2=(1+0.1) T1, i.e., original is negotiated after time-out time increases 10% as new negotiation time-out time.
2) when the circle queue has been expired, the maximum value of N number of network delay in the circle queue is obtained；It is N number of to detect this
Whether the maximum value of network delay is greater than y*T1, y > 0；If the maximum value that testing result is N number of network delay is greater than y*T1, then
Determine T2=(1+Y) T1；Y > 0.
Alternatively, when being added into 8 elements in circle queue, client obtains each in circle queue by taking Fig. 3 as an example
Network delay extracts maximum value therein, and compares the maximum value and T1Size relation between the 15% of/3, if the average value
Greater than T1The network delay of the 15% of/3, then the Ping message sent before explanation is bigger than normal, at this point it is possible to by new negotiation time-out
Time is determined as T2=(1+0.1) T1, i.e., original is negotiated after time-out time increases 10% as new negotiation time-out time.
3) when the circle queue has been expired, the average value of N number of network delay in the circle queue is obtained；It is N number of to detect this
Whether the average value of network delay is less than z*T1, z > 0；If the average value that testing result is N number of network delay is less than z*T1, then
Determine T2=(1-Z) T1；0 < Z < 1.
Alternatively, when being added into 8 elements in circle queue, client obtains each in circle queue by taking Fig. 3 as an example
Network delay extracts average value therein, and compares the maximum value and T1Size relation between the 10% of/3, if the average value
Less than T1The network delay of the 5% of/3, then the Ping message sent before explanation is less than normal, at this point it is possible to by new negotiation time-out
Time is determined as T2=(1-0.05) T1, i.e., original is negotiated into time-out time and reduced after 5% as new negotiation time-out time.
It should be noted that scheme shown in the embodiment of the present invention is only illustrated with above-mentioned specific example, in reality
In the application of border, the step-length of the above-mentioned threshold value for comparing and increase or diminution can be carried out according to the actual conditions of network
Adjustment, for example, in the case where needing to guarantee higher Detection accuracy, when detecting to need to increase negotiation time-out time,
Original can be negotiated into time-out time and once increase by 20%, in the case where needing to guarantee lower fault detection time delay, work as detection
When needing to reduce negotiation time-out time out, original can be negotiated into time-out time first-stage reduction 10%.
In the step 212, by the negotiation time-out time of the client by T1It is updated to T2。
In step 214, according to updated negotiation time-out time T2Subsequent heartbeat message is sent to the server.
As shown in figure 3, client passes through updated negotiation time-out time and sends after updating negotiation time-out time
Subsequent heartbeat message.
In the step 216, by the updated negotiation time-out time T2It is sent to the server.
For the ease of the new negotiation time-out time of server timely learning, client after updating and negotiating time-out time,
The updated negotiation time-out time is sent to by server by new type of message, so that server accurately carries out failure
Detection.
Client empties circle queue, and repeat above-mentioned steps 206- after updating negotiation time-out time
212, when circle queue is again filled with, further according to negotiation time-out time T2It will negotiate time-out with the network delay in circle queue
Time is updated to T3, recycle according to this.
