Fig. 3 b is the schematic diagram of another distributed cluster system based on the first gateway cluster and the second gateway cluster, In, the difference of Fig. 3 b and Fig. 3 a is, the first gateway cluster can not include in the distributed cluster system shown in Fig. 3 b One link management node, the second gateway cluster can not include the second link management node, remaining, the first gateway layer 302, second The structure of gateway layer 402, the first central node layer and the second central node layer is identical and in Fig. 3 a.Meanwhile in Fig. 3 b One central node is by the first gateway of one or more of the first gateway cluster at least one of second gateway cluster the Two gateways send heartbeat detection message, and the second central node is by the second gateway of one or more of the second gateway cluster to the The second gateway of at least one of one gateway cluster sends heartbeat detection message, to determine the first gateway cluster and the second gateway collection Communications status between group.At the same time, the heartbeat that the first gateway cluster sends the second central node in the embodiment of the present invention Detection message makes that main body that heartbeat detection replies message is also and different in the prior art, and the second gateway cluster is to the first centromere It is also and different in the prior art that the heartbeat detection message that point is sent makes the main body that heartbeat detection replies message.In the prior art First central node of the first gateway cluster needs the heartbeat detection message sent to the second central node of the second gateway cluster It sends heartbeat detection to reply message, the second central node of the second gateway cluster needs the first centromere to the first gateway cluster The heartbeat detection message that point is sent sends heartbeat detection and replies message, and in framework provided in an embodiment of the present invention, it is only necessary to the Any one second gateway in two gateway clusters returns the heartbeat detection message back heartbeat detection that the first central node is sent Answer message, the heartbeat detection message back heart that any one first gateway in the first gateway cluster sends the second central node Test returns message is jumped, in this way can be when a central node break down, another central node still can be received The heartbeat detection sent to other side replies message, when can be avoided due to a central node failure, in this section of failure Since the communication link between the gateway in the gateway cluster is normal in time, but another gateway cluster is due to can not receive net The heartbeat detection that the central node of pass cluster sends over replies message, and the communications status being mistakenly considered between group system is to disconnect 's.
As shown in figure 4, the embodiment of the present invention provides a kind of method for detecting group system communications status, the group system packet Include the first gateway cluster and the second gateway cluster, wherein the first gateway cluster includes the first central node and N number of first net It closes, the second gateway cluster includes the second central node and M the second gateways, one or more of N number of first gateway first There are communication links for the second gateway of at least one of gateway and the second gateway cluster, this method comprises:
S101, one or more first gateways send state-detection message, the state-detection message to the first central node It is used to indicate each first gateway and the second gateway cluster in the first gateway of one or more described in first gateway cluster In the second gateway between communication link communications status；
S102, the first central node reception state detect message；
S103, the first central node determine first gateway cluster and the second gateway collection according to state-detection message Communications status between group.
The embodiment of the present invention provides a kind of method for detecting group system communications status, is obtained and is used by the first central node The second net in the first gateway cluster of instruction in one or more first gateways in each first gateway and the second gateway cluster The state-detection message of the communications status of communication link between pass, then the first central node is determined according to state-detection message Communications status between first gateway cluster and the second gateway cluster, so that, the first central node is only needed according to first The communications status of the communication link between the second gateway in gateway and the second gateway cluster, that is, can determine the first gateway cluster with Communications status between second gateway cluster.In compared with the prior art, the first central node need to obtain the first gateway cluster and The communications status of every communication link between second gateway cluster, and first is determined according to the communications status of every communication link Communications status between gateway cluster and the second gateway cluster, detection group system communications status provided in an embodiment of the present invention Method can reduce by the first central node between the first gateway cluster and the second gateway cluster there are when magnanimity communication link Burden.
It is provided in an embodiment of the present invention it is a kind of detect group system communications status method can by the first gateway cluster Lai It executes, it specifically can be as the first central node and one or more in the first gateway cluster as shown in Fig. 3 a or Fig. 3 b First gateway executes.
In order to make it easy to understand, below with the detection group system communication in another embodiment the present invention will be described in detail embodiment The method of state, referring to Fig. 5, the method for another detection group system communications status provided in an embodiment of the present invention, the detection The method of group system communications status is applied in distributed cluster system as shown in Figure 3a, comprising:
S501, the first link management node obtain in each of the first gateway cluster the first gateway and the second gateway cluster The communications status of every communication link at least one communication link existing at least one second gateway.
The embodiment of the present invention obtains each of the first gateway cluster the first gateway and second to the first link management node The communications status of every communication link at least one communication link existing for the second gateway of at least one in gateway cluster Mode specifically can be the first gateway cluster and the second gateway cluster each other periodically by the first gateway collection without limiting Every communication link sends heartbeat detection message between group and the second gateway cluster, and then the first link management node is according to from every The heartbeat detection that other side's feedback whether is received on communication link replies message communications status to confirm communication link, example Property, if the first central node sends heartbeat detection message, and the first link to the second gateway cluster by the first communication link Management node determination receives reply namely heartbeat of second gateway cluster to this heartbeat detection message on the first communication link Test returns message, then the first link management node determines that the communications status of first communication link is normal, otherwise, it determines should The communications status of first communication link is to disconnect.
The communications status of every communication link is reported to belonging to every communication link by S502, the first link management node First gateway.
On the one hand, the embodiment of the present invention can be stored with the mark of each first gateway in the first link management node, And the mark of the corresponding every communication link of each first gateway, the mark of every communication link are used to indicate the communication chain First gateway and the second gateway belonging to road；In this way, when each of first link management nodal test to the first gateway cluster The communication of every communication link in first gateway and the second gateway cluster in communication link existing at least one second gateway After state, the communications status of each communication link can be reported to corresponding first gateway.Illustratively, if the first link What management node determined the first link is identified as 01, and the mark 01 of first link indicates that first link belongs to the first net It closes, then the first link management node is after the communications status for detecting first link, by the communications status of first link It is reported to the first gateway.
On the other hand, the first link management node can also get the first gateway cluster and in the embodiment of the present invention Between two gateway clusters after the communications status of existing every communication link, the communications status of every communication link is reported Give each of one or more first gateways the first gateway, so that the first gateway of each of one or more first gateways According to the mark of every communication link and it is stored in the corresponding every communication link of first gateway in each first gateway It identifies, obtains first gateway in the communications status of every communication link between the first gateway cluster and the second gateway cluster The communications status of corresponding every communication link.Illustratively, there are three between the first gateway cluster and the second gateway cluster First gateway, there are 8 communication links between three first gateways and the second gateway cluster, then the first link management node is examined The communications status of 8 communication link is surveyed, and 8 communication links are reported to three the first gateways.Wherein, the first gateway cluster And second existing every communication link between gateway cluster refer to the first gateway of one or more of first gateway cluster and Every communication link in two gateway clusters in communication link existing at least one second gateway.
The third aspect of course for the processing load for reducing each first gateway, while reducing by the first link management node Burden, in the embodiment of the present invention the first link management node can also detect each first gateway it is corresponding at least one (at least one corresponding communication link of each first gateway refers in first gateway and the second gateway cluster at least communication link Existing communication link between one the second gateway) in the first communication link (the first communication link be the first link management node First communications status detected is normal communication in detecting corresponding at least one communication link of each first gateway Link) state be it is normal when, then by the communications status of first communication link be normal first link event be reported to this First gateway belonging to first communication link, and the first gateway is corresponding to remove first without reporting belonging to first communication link The communications status of remaining communication link except communication link；As long as namely the first link management nodal test is into the first gateway It is normal communication link there are a communications status, then can have to detect the corresponding every communication link of first gateway Communications status, and to the first gateway report the first link event (it is corresponding that first link event is used to indicate first gateway There are normal communication links at least one communication link), but if in corresponding at least one communication link of the first gateway The communications status of every communication link is to disconnect, then needs logical by every in corresponding at least one communication link of the first gateway The communications status of letter link is reported to the first gateway, and certain first link management node can report the second link to the first gateway (second link event is used to indicate in corresponding at least one communication link of first gateway is not present normal communication chain to event Road or second link event are used to indicate every communication link in corresponding at least one communication link of first gateway It is to disconnect).
S503, each first gateway are according to every communication link in corresponding at least one communication link of first gateway Communications status determines the communications status of each first gateway, wherein the communications status of each first gateway refer to first gateway with Communications status between second gateway cluster.
Illustratively, the communications status of the first gateway is normal, then shows in first gateway and the second gateway cluster It in existing communication link there are the communications status of at least one communication link is normal between at least one second gateway.
The communications status of first gateway is to disconnect, then shows at least one of first gateway and second gateway cluster the The communications status of all communication links is to disconnect in existing communication link between two gateways.
On the one hand, include when each first gateway receives the link state detection message that the first link management node reports When the communications status of corresponding at least one communication link of first gateway, then each first gateway is only needed according to respectively corresponding The communications status of at least one communication link determine itself communications status.
On the other hand, message package is detected when each first gateway receives the link state that the first link management node reports Include every in each first gateway and the second gateway cluster at least one communication link existing at least one second gateway The communications status of communication link, then each first gateway then needs the mark according to each communication link, from each first gateway With the communication of every communication link at least one communication link existing at least one second gateway in the second gateway cluster Corresponding at least one communication link of each first gateway is obtained in state, and according to corresponding at least one communication link Communications status determine the communications status of the first gateway.
The third aspect detects message package when each first gateway receives the link state that the first link management node reports Corresponding first link event of each first gateway or corresponding second link event of each first gateway are included, then receives First gateway of one link event determine the communications status of first gateway be it is normal, then receive the first of the second link event Gateway determines the communications status of first gateway to disconnect.
Due to for each first gateway, determining that the mode of state-detection message and principle are all the same, therefore, this Only illustrate by taking the three the first gateways as an example in inventive embodiments, the side for determining the communications status of each first gateway is discussed in detail Method, the three the first gateways are any one in the first gateway of at least one of the embodiment of the present invention, and are not had any Indicative meaning.
Specifically, step S503 can be accomplished by the following way:
S5031, exist at least when in the three the first corresponding communication links of gateway that the first link management node reports The communications status of one communication link be it is normal, then the three the first gateways determine that the three the first gateway communication states are normal.
Illustratively, if there are 3 articles between the three the first the second gateways of at least one of gateway and the second gateway cluster Communication link, for example, communication link 1, communication link 2 and communication link 3, if communication link 1, communication link 2 and communication It is/normal/when disconnecting that the communications status of link 3 is respectively as follows: disconnection, then the three the first gateways determine the three the first gateway communication shapes State is normal or the communications status of communication link 1, communication link 2 and communication link 3 is respectively as follows: normal/disconnection/disconnection When, then the three the first gateways determine that the three the first gateway communication states are normal.
S5032, when every communication in the three the first corresponding communication links of gateway that the first link management node reports The communications status of link is to disconnect, then the three the first gateways determine the three the first gateway communication states to disconnect.
Illustratively, if the communications status of communication link 1, communication link 2 and communication link 3 is respectively as follows: disconnection/disconnected When opening/disconnecting, then the three the first gateways determine the three the first gateway communication states to disconnect.
Each first gateway sends first gateway to the first central node and corresponds in S504, one or more first gateways State-detection message.
Illustratively, the first gateway 3021 is by the communications status of the second gateway of at least one of itself and the second gateway cluster The first central node is sent to for normal state-detection message；Second gateway 3022 by its in the second gateway cluster at least The communications status of one the second gateway is that the state-detection message disconnected is sent to the first central node；First gateway 3023 by its Communications status with the second gateway of at least one of the second gateway cluster is that normal state-detection message is sent in first Heart node.
S505, the first central node receive the state-detection that each first gateway reports in one or more first gateways and disappear Breath.
S506, the first central node according to state-detection message determine the first gateway cluster and second gateway cluster it Between communications status.
Wherein, step S506 can specifically be accomplished by the following way:
S5061, determine that state detecting information shows one or more of first gateway cluster when the first central node In one gateway there are the communications status between the second gateway at least one first gateway and the second gateway cluster be it is normal, then Show that the communications status between the first gateway cluster and second gateway cluster is normal.
Illustratively, if the first central node determines that the state-detection message that the first gateway 3021 reports indicates first net It closes the state-detection message that 3021 communications status is normal or the first gateway 3022 reports and indicates first gateway 3022 The state-detection message that communications status is normal or the first gateway 3023 reports indicates the communications status of first gateway 3023 To be normal, then the first central node determines that the communications status between the first gateway cluster and second gateway cluster is normal. The communications status of first gateway is normally to refer between the second gateway of at least one of first gateway and the second gateway cluster It there are the communications status of at least one communication link is normal in existing communication link.
S5062, determine that state detecting information shows in N number of first gateway in the first gateway cluster when the first central node The first gateway of one or more in communications status between M the second gateways in each first gateway and the second gateway cluster It is to disconnect, then shows the communications status between the first gateway cluster and the second gateway cluster to disconnect.
Illustratively, if the first central node determines that the state-detection message that the first gateway 3021 reports indicates first net The communications status for closing 3021 is to disconnect, and the state-detection message that the first gateway 3022 reports indicates the logical of first gateway 3022 Letter state is to disconnect and the state-detection message that reports of the first gateway 3023 indicates that the communications status of first gateway 3023 is It disconnects, then the first central node determines the communications status between the first gateway cluster and second gateway cluster to disconnect.The The communications status of one gateway is to disconnect referring to depositing between the second gateway of at least one of first gateway and the second gateway cluster Communication link in all communication links communications status be disconnect.
The embodiment of the present invention receives the state-detection message that each first gateway reports by the first central node, to determine Communications status between first gateway cluster and the second gateway cluster, such first central node only need to be concerned about each first net Close the communications status to the second gateway cluster.For example, there are 64 gateways in the first gateway cluster, have 256 on each gateway Item to the second gateway cluster communication link, then according to technical solution described in the prior, then the first central node It needs to detect the communications status of 64*256=16384 communication link, and is determined according to the communications status of 16384 communication links Communications status between first gateway cluster and the second gateway cluster, and when using technical solution as described in Figure 5, first Central node only needs to manage 64 gateways to the communications status of the second gateway cluster, therefore can greatly reduce center The pressure of node.
In order to make it easy to understand, below with the detection group system communication in another embodiment the present invention will be described in detail embodiment The method of state, referring to Fig. 6, the method for another detection group system communications status provided in an embodiment of the present invention, the detection The method of group system communications status is applied in distributed cluster system as shown in Figure 3b, the collection of the distribution shown in Fig. 3 b In group's system, the first gateway of at least one of first gateway cluster is used to send the second central node of the second gateway cluster Heartbeat detection message make a response, replied message with replying heartbeat detection, the second net of at least one of second gateway cluster It closes the heartbeat detection message sent for the first central node to the first gateway cluster to make a response, with to the first gateway cluster Reply heartbeat detection message, comprising:
S601, the first central node send the first instruction message to the first gateway of one or more of N number of first gateway, Heart beat status detection message is carried in first instruction message；First instruction message indicates that the first gateway examines heart beat status It surveys message and is sent in the second gateway cluster that there are at least one second gateways of communication link with first gateway.
S602, the one the first gateways receive first instruction message；And first instruction message is sent to the second gateway There are at least one second gateways of communication link with first gateway in cluster；Wherein, the one the first gateways are to receive the First gateway of the first instruction message that one central node is sent.
S603, one or more first gateways judge whether to receive one or more second gateways in the second gateway cluster At least one of the second gateway send heartbeat detection reply message, however, it is determined that receive in the second gateway cluster one or more The heartbeat detection that the second gateway of at least one of a second gateway is sent replies message, and thens follow the steps S604；Otherwise, it executes S605；
S604, it heartbeat detection is replied message is sent to the first central node.
S605, it continues to test and whether receives heartbeat detection and reply message.
S606, the first central node are after determining that the heartbeat detection for receiving the transmission of the first gateway replies message, then really Communications status between fixed first gateway cluster and second gateway cluster is normal.
S607, the first central node be not if it is determined that continuous several times receive the heartbeat of the first gateway transmission in predetermined period Test returns message, it is determined that the communications status between the first gateway cluster and second gateway cluster is to disconnect.
Fig. 7 show the heartbeat path of first gateway cluster of detection moment in predetermined period, specific as follows: the One central node first therefrom selects first gateway according to the communications status between the first gateway cluster and the second gateway cluster A2, the communications status between first gateway A 2 and the second gateway cluster be it is normal, the first central node is by heartbeat detection message It is sent to the first gateway A 2, the first gateway A 2 selects a communications status for normal communication link, heartbeat detection message is sent out Be sent to the second gateway cluster, it is assumed that in the second gateway cluster with the first gateway A 2 there are a communications status be normal communication chain Second gateway on road is the second gateway B2, at this point, heartbeat detection message will not be issued the second central node B by the second gateway B2, But the heartbeat detection message directly sent to first gateway A 2 makes reply, and sends heartbeat detection and reply message.Specifically , the second gateway B2 selects in one and the first cluster between at least one first gateway existing communication link by heartbeat detection The first gateway A 3 being sent in the second gateway cluster is replied message, the first gateway A 3 gives the first central node A, completes one Heartbeat loopback, at this point, the first central node A determines that the communications status between the first gateway cluster and the second gateway cluster is positive Often.
Since the first central node needs to know between each the first gateway cluster of detection moment and the second gateway cluster Communications status, therefore, the first central node of each detection moment in predetermined period can select first gateway to send the heart Detection message is jumped, (for example, a predetermined period includes three moment, the first moment, the second moment and third moment, one The first central node only can send heartbeat detection message by one central node of selection in a predetermined period, for example, only selecting the One gateway A 2 sends heartbeat detection message, also can choose one or more first gateways and sends heartbeat detection message, for example, the One moment sent heartbeat detection message by the first gateway A 1, and the second moment sent heartbeat detection message by the second gateway A 2, The third moment sends heartbeat detection message by third gateway A 3 or the first moment selected the first gateway A 2 to send heartbeat detection Message, the second moment select the first gateway A 3 to send heartbeat detection message, and the third moment selects the first gateway A 2 to send heartbeat inspection Survey message etc.).First replied message due to receiving the heartbeat detection that at least one second gateway is sent in the second gateway cluster Gateway is the selected communication of the second gateway according to the heartbeat detection message for receiving the transmission of the first gateway in the second gateway cluster What link determined, and there are at least one to communicate for the first gateway of at least one of each second gateway and first gateway cluster Link, therefore, receive the first gateway send heartbeat detection message the second gateway selection the first gateway may and Xiang Qifa The first gateway for sending heartbeat detection message is the same gateway, it is also possible to be with the first gateway for being sent to it heartbeat detection message Different gateways.
Since each moment of first central node in predetermined period can pass through one in the first gateway cluster Second gateway of one gateway into the second gateway cluster sends heartbeat detection message, at the same time, if communication link is just The heartbeat detection that Chang Zehui receives the second gateway feedback replies message, therefore, in the embodiment of the present invention, if the first central node Determine that preset times continuous in predetermined period do not receive the heartbeat detection that one or more first gateways are sent and reply message, Then determine that the communications status between the first gateway cluster and the second gateway cluster is to disconnect.
The embodiment of the present invention, without restriction, can according to need and be selected to above-mentioned predetermined period, the preset times Also it can according to need and be configured, for example, if not receiving the heartbeat detection that one or more first gateways are sent for continuous 5 times It replies message, it is determined that the communications status between the first gateway cluster and the second gateway cluster is to disconnect.
Since in actual use, group system as shown in Figure 2 may have following situations: due to link Event (including link state is normal or disconnects) is taken office when being reported to the first gateway cluster and the second gateway cluster reporting Anticipate a gateway cluster when there may be delays, such that being examined in the first gateway cluster of synchronization and the second gateway cluster The communications status between group system measured is inconsistent, for example, there are three links between gateway cluster A and gateway cluster B, Link event (including link state is normal or disconnects) is reported to central node A and central node B used time under normal circumstances For 1 chronomere, but it is also possible to be delayed.Link 2 and link 3 are already off before the moment 1, and link 2 and chain Link 2 and 3 link event of link are notified central node B, link 2 and link 3 to distinguish by corresponding second gateway in road 3 The link event of link 2 and link 3 is notified central node A by corresponding first gateway, and at the moment 1, link 1 is disconnected, and The link event of link 11 moment that has been delayed in gateway cluster A just reaches central node A, if link 3 connects again at the moment 2 On, the state of link 3 becomes normally, and the corresponding link event of link 3 reaches central node B at the moment 3, then, such as table 1 Shown: at the moment 1, the state of link 1 existing for the gateway cluster A and gateway cluster B that central node A is determined is normal, link 2 State be to disconnect, the state of link 3 is to disconnect, link 1 existing for the gateway cluster A and gateway cluster B that central node B is determined State be to disconnect, the state of link 2 is to disconnect, and the state of link 3 is to disconnect；At the moment 2, central node A determining link 1 State be to disconnect, the state of link 2 is to disconnect, the state of link 3 be it is normal, the state of central node B determining link 1 is It disconnects, the state of link 2 is to disconnect, and the state of link 3 is to disconnect；At the moment 3, the state for the link 1 that central node A is determined is Disconnect, the state of link 2 is to disconnect, the state of link 3 be it is normal, the state for the link 1 that central node B is determined is disconnection, chain The state on road 2 be disconnect, the state of link 3 be it is normal, therefore, think net in moment 1,3 central node A of moment 2 and moment It is normal for closing the state of cluster A；And for central node B, gateway cluster A is thought in 2 central node B of moment 1 and moment State between gateway cluster B is to disconnect, and just thinks that the state between gateway cluster A and gateway cluster B is extensive from disconnecting at the moment 3 It is multiple to arrive normally.
