Embodiment
The present invention is a kind of heartbeat detection scheme, is applied to have in the network equipment of service network port, and its basic thought is: the network equipment periodically sends heartbeat message by the heartbeat detection port to detecting the opposite end, receives to detect the heartbeat response of returning the opposite end; When the heartbeat detection port is not received the heartbeat response that detects the opposite end, select a current service network port that does not have business, send heartbeat message by selected service network port to detecting the opposite end; Judge whether service network port receives the heartbeat response that detects the opposite end; If it is normal then to determine to detect the opposite end; Otherwise it is unusual to determine to detect the opposite end.Detecting under the unusual situation in opposite end, can take over to detect the opposite end business and restart and detect the opposite end.
As seen, heartbeat detection scheme of the present invention is provided with multiple detection, when the heartbeat detection port does not receive the heartbeat response, does not judge at once that the opposite end is unusual, but proceeds to detect by service network port.And, the service network port that is adopted is not have professional service network port, even all service network ports all have the business migration of professional also can be a certain selected service network port to arrive other service network ports, the service network port that this is selected is specifically designed to heartbeat detection, guarantee that heartbeat message and/or heartbeat sound would not be dropped because of the service network port heavy traffic, improved the success rate that successfully receives the heartbeat response, thereby improved accuracy of judgement degree, and then reduced because of error in judgement causes the opposite end and under non-abnormal conditions, be interrupted professional probability the opposite end state.
Preferably, the heartbeat detection port comprises the heartbeat detection network interface and the serial ports that are specifically designed to heartbeat detection of embodiment of the invention setting, and sends heartbeat message by heartbeat detection network interface and serial ports to detecting the opposite end simultaneously; When heartbeat detection network interface is not received the heartbeat response that detects the opposite end, judge whether the heartbeat detection of serial ports is normal; Only do not receive all under the situation of the heartbeat response that detects the opposite end that at heartbeat detection network interface and serial ports it is unusual just to determine to detect the opposite end.Thereby guarantee under the unusual situation of heartbeat detection network interface, can judge the state of opposite end rapidly from the detection case of serial ports.This with detect earlier with the heartbeat detection network interface, treat that the unusual implementation that detects with serial ports again of network interface compares, detect in the time of serial ports and network interface and can reduce by two mouthfuls of unnecessary waiting time when switching, play the effect of rapid judgement.
Technical scheme of the present invention goes for the heartbeat detection between host apparatus and the stand-by equipment.When describing technical scheme of the present invention, being applied to the network store system shown in Fig. 1 with heartbeat detection scheme of the present invention is that example is described below, and the double storage controllers in this network store system is active and standby each other.
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, describe the present invention.
Fig. 2 shows storage control A in the embodiment of the invention carries out heartbeat detection to storage control B method flow diagram.Storage control B is identical to the method principle that storage control A carries out heartbeat detection.As shown in Figure 2, this flow process may further comprise the steps:
Step 201: whether storage control A is in real time to self existing business to monitor, and the record traffic monitoring result.
In this step, judge in the set time section whether have data service, if, judge that then there is business in self, otherwise, judge that self does not have business.Wherein, the set time section can be a heart beat cycle.Heart beat cycle is meant the time interval of double transmission heartbeat message.
The execution that constantly circulates of this step.
Step 202: with the heart beat cycle is circulating unit, periodically sends heartbeat message to storage control B simultaneously by heartbeat detection network interface and serial ports.
The present embodiment difference with the prior art not only is simultaneously to send heartbeat message by heartbeat detection network interface and serial ports, and present embodiment to send heartbeat message be circulating unit with the heart beat cycle, irrelevant with the time that receives the heartbeat response.Therefore, after need not to wait to receive heartbeat response, need to wait for that a heart beat cycle could send next heartbeat message as prior art.Because present embodiment need judge repeatedly that the overtime just judgement of heartbeat detection network interface heartbeat detection network interface is unusual, so such design can be shortened judgement time.
Step 203: after heartbeat message is sent out, adopt the default heartbeat timeout time at every turn, judge in the heartbeat response that whether the heartbeat detection network interface receives storage control B feedback in the time of current heartbeat timeout as the current heartbeat timeout time; If then after sending heartbeat message, continue the judgement of execution in step 203 next time; Otherwise, execution in step 204.
When carrying out heartbeat detection by the heartbeat detection network interface, judge synchronously whether serial ports receives the heartbeat response in the current heartbeat timeout time, if, it is normal to determine that then serial ports detects, record serial ports detected state, otherwise, it is unusual to determine that serial ports detects, record serial ports detected state.The serial ports detected state of record is as the basis for estimation of step 207.
Step 204: judge heartbeat timeout, accumulative total successive heartbeat expired times; Selection is different from the self-defined heartbeat timeout time of current heartbeat timeout time, as the current heartbeat timeout time of heartbeat timeout judgement next time.
Wherein, Lei Ji successive heartbeat expired times are cleared after the heartbeat detection network interface receives the heartbeat response.
In this step, selecting to be different from the self-defined heartbeat timeout time of current heartbeat timeout time can have multiple mode, and present embodiment is introduced two kinds of preferably selection modes:
Mode one, random fashion.In preset range, select the self-defined heartbeat timeout time at random.For example, the self-defined heartbeat timeout time is: basic value adds 0 second random value between (s)-2s, and the granularity of random value is 0.1s.If basic value is 1.5s, then selecting the preset range of self-defined heartbeat timeout time at random is exactly 1.5s-3.5s.
The storage control that adopts random fashion can reduce mutual backup is restarted the probability of opposite end simultaneously, and reason is: in the present embodiment, the storage control of backup is arranged in the same hardware frame physically mutually, therefore can restart the opposite end by hardware.Heartbeat path between storage control A and storage control B (comprising the path that described heartbeat detection network interface, serial ports are connected with service network port) fault, when causing detection to respond less than the opposite end heartbeat, storage control A and storage control B all can judge simultaneously that in this process step 210 opposite end is unusual, and then restart the opposite end.But storage control A and storage control B may be in the normal process business, belong to non-restarting under unusual, and the business of storage control A and storage control B all is interrupted so.In order to reduce the probability of happening of this situation as far as possible, present embodiment adopts random fashion to determine the self-defined heartbeat timeout time, so because the self-defined heartbeat timeout asynchronism(-nization) that storage control A and storage control B select, the two judges that the unusual moment of opposite end is also different, greatly reduces the probability of restarting the opposite end simultaneously.If selecting the range spans of self-defined heartbeat timeout time at random is 2s, and granularity is 0.1s at random, and 3 heartbeat timeouts are set think that heartbeat is unusual, storage control A and the storage control B probability of restarting the opposite end simultaneously will be reduced to 1/400 so.
In the present embodiment, when judging for the first time heartbeat detection network interface heartbeat timeout, then select the self-defined heartbeat timeout time at random, in practice, can when judging whether heartbeat timeout preceding m-1 time, all adopt the default heartbeat timeout time, and occur heartbeat timeout continuously m-1 time, select at random in judgement, guarantee that the time-out time that last judgement is used is random value, can reach the purpose that the opposite end probability is restarted in reduction simultaneously equally.Wherein, m is an overtime time threshold value.But, repeatedly adopt random value can further reduce the probability of restarting the opposite end simultaneously.
Mode two, keep out of the way mode.Increase progressively on current heartbeat timeout time basis, the heartbeat timeout time after will increasing progressively is as the self-defined heartbeat timeout time.For example, the computing formula that the self-defined heartbeat timeout time is set is: self-defined heartbeat timeout behind the n time heartbeat timeout time=default heartbeat timeout time+n+n*n*0.1, wherein, n is a positive integer, and 0.1 for adjusting the factor.Suppose that the default heartbeat timeout time is 1.5 seconds (s), then behind the generation heartbeat timeout first time, the self-defined heartbeat timeout time is 1.5+1+0.1=2.6s; After the heartbeat timeout second time took place, the self-defined heartbeat timeout time was 1.5+2+2 * 2 * 0.1=3.9s.
Mode is kept out of the way in employing, can increase progressively the heartbeat timeout time step by step after not receiving for the first time opposite end heartbeat response, thus avoid because of the heartbeat timeout time too short, cause not receiving the drawback that the heartbeat response is brought.If storage control A selects the different adjustment factors for use with storage control B, the self-defined heartbeat timeout time of the two selection also can reduce the probability of restarting the opposite end simultaneously as random fashion with difference so.Select the different adjustment factors for different storage controls the different granularities that increases progressively to be set in fact exactly, in practice, also can select to increase progressively granularity at random.
Step 205: whether the successive heartbeat expired times of judging accumulative total are more than or equal to the preset times threshold value; If then execution in step 207; Otherwise, execution in step 206.
For example, the preset times threshold value can be set to 2 or 3.
Step 206: after heartbeat message is sent out, judge whether in current time-out time, to receive the heartbeat response; If then execution in step 203; Otherwise, execution in step 204.
Step 207: judge whether serial ports detects normal; If then execution in step 211; Otherwise, execution in step 208.
Wherein, judge whether serial ports detects normal according to being: the serial ports detected state of step 203 record.
Step 208: select a current service network port that does not have business, send heartbeat message to storage control B by selected service network port.
In this step, judge self whether to exist to be in the service network port that does not have service condition, if then from be in the service network port that does not have service condition, select one, as selected service network port; Otherwise, previously selected service network port as selected service network port, and is suspended the business of selected service network port.Before the business of suspending selected service network port, give other service network ports with the IP address configuration of service port to be suspended, like this, the business of the service network port that is suspended is moved on other service network ports, guarantees professional continuity.
When storage control B sends heartbeat message, adopt pre-configured service network port to be in the IP address of the same network segment by selected service network port, send heartbeat message to storage control B with storage control B.
Step 209: judge whether service network port receives the heartbeat response of storage control B, if then execution in step 212; Otherwise, execution in step 210.
Step 210: determine that storage control B is unusual, restart storage control B according to the professional monitoring result of step 201.This flow process finishes.
In this step, restart storage control B according to the professional monitoring result of step 201 and comprise:
Judge according to the professional monitoring result of step 201 whether self currently has professional an existence, if, then restart storage control B, take over the business of storage control B; Otherwise, after waiting for a period of time, restart storage control B, take over the business of storage control B.Stand-by period can set in advance, and for example is set to 3.5s.
Present embodiment supposes that self having under the professional situation opposite end does not have business, restarts the opposite end; And self do not having under the professional situation, suppose that the opposite end has and do not have business, self is restarted in the wait opposite end, and the other side is not restarted self, restarts the opposite end again.The purpose of doing like this is further to reduce the detection both sides and restart all interrupted probability of business that the opposite end causes both sides simultaneously.
In the operation of the business of restarting storage control B and adapter storage control B, present embodiment is restarted storage control B earlier, takes over the business of storage control B again, and the blanking time of these two operations can be very of short duration.Because the business of taking over so, when both sides determine to restart the opposite end simultaneously, can be avoided such a case after restarting the opposite end: both sides fight for before restarting the opposite end and take over the confusion that the opposite end resource causes.
Step 211: alarm, and in subsequent heartbeats detects, detect heartbeat by serial ports.
The purpose of alarm is to notify the keeper to check the heartbeat detection network interface, to remove the fault of heartbeat detection network interface.Recover the detection of heartbeat detection network interface after the trouble shooting.
In follow-up process by serial ports detection heartbeat, attempt simultaneously carrying out heartbeat detection with the heartbeat detection network interface, if receive the heartbeat response, then as shown in phantom in Figure 2, return execution in step 203 by the heartbeat detection network interface.
Step 212: alarm, and in subsequent heartbeats detects, detect heartbeat by service network port.
The purpose of alarm is to notify the keeper to check heartbeat detection network interface and serial ports, with the fault of releasing heartbeat detection network interface and the fault of serial ports.Recover the detection of heartbeat detection network interface and serial ports after the trouble shooting.
In follow-up process by service network port detection heartbeat, attempt simultaneously carrying out heartbeat detection with the heartbeat detection network interface, if receive the heartbeat response, then as shown in phantom in Figure 2, return execution in step 203 by the heartbeat detection network interface.
So far, this flow process finishes.
In order to realize heartbeat detecting method of the present invention, the embodiment of the invention has also proposed a kind of heartbeat detection apparatus.Heartbeat detection apparatus can be applied among the storage control A and storage control B of Fig. 1.
Fig. 3 is the structural representation of heartbeat detection apparatus in the embodiment of the invention.As shown in Figure 3, this heartbeat detection apparatus comprises heartbeat detection unit 31, heartbeat detection port unit 32 and n service network port 33, and n is the integer more than or equal to 1; Wherein,
