In order to be further described the scheme shown in above-mentioned Fig. 1, please refer to Fig. 2, it illustrates the method flow diagram of the heartbeat message sending method that another embodiment of the present invention provides.This heartbeat message sending method may be used in client.This heartbeat message sending method can comprise:
In step 202., with T
1/ 3 send N number of heartbeat message for the cycle to server, T
1for the negotiation time-out time of client.
Client is when being connected with server, consulting time-out time with 1/3rd is the cycle send heartbeat message to server, also referred to as Ping message, if the network between client and server is unobstructed, server receives this Ping message smoothly, then can return a Pong message to client, identical information is carried in this Ping message and Pong message, if client receives the Pong message of client end response in the scheduled time after Ping message sending, then confirm with the connection of server normal.
In embodiments of the present invention, system time when type of message, message ID and client send Ping message can only be carried in the Ping message that sends of user end to server and the Pong message that returns of server; The message ID carried in the Ping message successively sent can increase progressively successively.
In step 204, for each heartbeat message in this N number of heartbeat message, when receiving response message corresponding to this heartbeat message, obtain the system time t comprised in this response message
1, and the system time t of this terminal when this response message is received
2.
When client receives a Pong message, can extract and to carry in this Pong message, client sends system time during corresponding Ping message.Client also obtains system time when receiving this Pong message simultaneously.
In step 206, the network delay δ=t of this heartbeat message is determined
2-t
1.
System time during this client got transmission Ping message and the time interval between system time when receiving corresponding Pong message are retrieved as the network delay of this Ping message by client.
In a step 208, to be added into by the network delay δ of this heartbeat message and to pre-set, length is the circle queue of N.
Pre-setting a length in client is N number of circle queue, if client obtains the network delay of a Ping message, and this circle queue state less than, then the network delay of this Ping message is added in this circle queue as an element.
Concrete, network delay as shown in Figure 3 obtains and consults time-out time and upgrades schematic diagram, and wherein, client is with T
1/ 3 is the cycle send Ping message to server, when server receives Ping message at every turn, namely return a corresponding Pong message to client, sending Ping message to the time received corresponding Pong message from client is network delay δ this Ping message.In figure 3, circle queue length is fixed as 8, each network delay δ that client will get
1, δ
2, δ
3δ
8be added into circle queue.
In step 210, according to the network delay of this N number of heartbeat message and the negotiation time-out time T of this client
1determine new negotiation time-out time T
2.
Concrete, client can determine new negotiation time-out time according to three kinds of modes below:
1) when this circle queue is expired, the mean value of the N number of network delay in this circle queue is obtained; Whether the mean value detecting this N number of network delay is greater than x*T
1, x > 0; If testing result is the mean value of this N number of network delay be greater than x*T
1, then T is determined
2=(1+X) T
1; X > 0.
For Fig. 3, when being added into 8 elements in circle queue, client obtains each network delay in circle queue, calculates its mean value, and compares this mean value and T
1/ 3 10% between magnitude relationship, if this mean value is greater than T
1/ 3 10%, then the network delay of Ping message sent before illustrating is bigger than normal, now, new negotiation time-out time can be defined as T
2=(1+0.1) T
1, as new negotiation time-out time after increasing 10% by former negotiation time-out time.
2) when this circle queue is expired, the maximum of the N number of network delay in this circle queue is obtained; Whether the maximum detecting this N number of network delay is greater than y*T
1, y > 0; If testing result is the maximum of this N number of network delay be greater than y*T
1, then T is determined
2=(1+Y) T
1; Y > 0.
Or for Fig. 3, when being added into 8 elements in circle queue, client obtains each network delay in circle queue, extracts maximum wherein, and compares this maximum and T
1/ 3 15% between magnitude relationship, if this mean value is greater than T
1/ 3 15%, then the network delay of Ping message sent before illustrating is bigger than normal, now, new negotiation time-out time can be defined as T
2=(1+0.1) T
1, as new negotiation time-out time after increasing 10% by former negotiation time-out time.
3) when this circle queue is expired, the mean value of the N number of network delay in this circle queue is obtained; Whether the mean value detecting this N number of network delay is less than z*T
1, z > 0; If testing result is the mean value of this N number of network delay be less than z*T
1, then T is determined
2=(1-Z) T
1; 0 < Z < 1.
Or for Fig. 3, when being added into 8 elements in circle queue, client obtains each network delay in circle queue, extracts mean value wherein, and compares this maximum and T
1/ 3 10% between magnitude relationship, if this mean value is less than T
1/ 3 5%, then the network delay of Ping message sent before illustrating is less than normal, now, new negotiation time-out time can be defined as T
2=(1-0.05) T
1, reduce after 5% as new negotiation time-out time by former negotiation time-out time.
It should be noted that, scheme shown in the embodiment of the present invention is only illustrated with above-mentioned instantiation, in actual applications, can adjust above-mentioned threshold value for comparing and increase or the step-length that reduces according to the actual conditions of network, such as, when needing to ensure higher Detection accuracy, when detecting that needs increase negotiation time-out time, former negotiation time-out time once can be increased by 20%, when needing to ensure lower fault detect time delay, when detecting that needs reduce negotiation time-out time, can by former negotiation time-out time first-stage reduction 10%.
In the step 212, by the negotiation time-out time of this client by T
1be updated to T
2.
In step 214, according to the negotiation time-out time T after renewal
2follow-up heartbeat message is sent to this server.
As shown in Figure 3, after time-out time is consulted in renewal, namely client sends follow-up heartbeat message by the negotiation time-out time after renewal.
In the step 216, by the negotiation time-out time T after this renewal
2send to this server.
Know new negotiation time-out time in time for the ease of server, the negotiation time-out time after this renewal, after time-out time is consulted in renewal, is namely sent to server by new type of message, so that server accurately carries out fault detect by client.
Client, after time-out time is consulted in renewal, namely empties circle queue, and repeats above-mentioned steps 206-212, when circle queue is full of again, then according to negotiation time-out time T
2with the network delay in circle queue, negotiation time-out time is updated to T
3, circulate according to this.
