Embodiment
Below with reference to accompanying drawings exemplary embodiment of the present disclosure is described in further detail.Although show exemplary embodiment of the present disclosure in accompanying drawing, however should be appreciated that can realize the disclosure in a variety of manners and not should limit by the embodiment set forth here.On the contrary, provide these embodiments to be in order to more thoroughly the disclosure can be understood, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
Frequently send the problem of heartbeat message to solve terminal, embodiments provide a kind of method sending heartbeat message, as shown in Figure 1, the method comprises:
101, periodically main heartbeat message is sent to server.
The heartbeat response packet that described main heartbeat message in step 101 returns for obtaining described server.In the network operation process of reality, terminal needs to perform multitask operation under the mandate of the server of network side, and therefore terminal needs the presence remaining on network side.It is by periodically realizing to the mode of server transmission heartbeat message that terminal maintains its presence.When server has new task indicating terminal to perform, will the heartbeat message that the terminal received sends be responded, perform new task to authorization terminal.It is no matter the heartbeat message of which kind of form, it is sent out periodically to server, can determine after server receives that terminal is in network connection state, if server needs authorization terminal to perform new task, then server can respond the heartbeat message that terminal sends, and issues the instruction performing new task to terminal.If server does not receive the heartbeat message of terminal transmission every certain hour, then server can judge that terminal disconnects, thus carries out corresponding terminal disconnection logical process.
In the present embodiment, for keeping the heartbeat message of terminal presence to be defined as main heartbeat message, the heartbeat response packet that described main heartbeat message returns for obtaining server.Main heartbeat message not only plays a part to keep terminal presence, and periodically sends main heartbeat message to server server can also be made to respond main heartbeat message at any time, issues new heartbeat response packet in time to terminal.
102, the heartbeat response packet of reception server transmission.
Described heartbeat response packet in step 102 carries the executing state parameter for different task.Periodically send in the process of main heartbeat message in above-mentioned steps 101 to server, if server does not have new task to want authorization terminal to perform, then server can not respond the main heartbeat message that terminal sends, and described main heartbeat message only plays a part the presence keeping terminal at network side.When server has new task to want authorization terminal to perform, server can respond the main heartbeat message that terminal sends, and issues task-performance instructions to terminal.Described task-performance instructions can be realized by the mode of heartbeat response packet, can carry the executing state parameter for different task in described heartbeat response packet.
Above-mentioned have new task to want authorization terminal to perform when server time, the main heartbeat message that server might not send terminal immediately respond and issue heartbeat response packet, server also can respond the main heartbeat message that terminal sends and issue heartbeat response packet again after obtaining a part of new task after a while, to make can carry in heartbeat response packet more for the executing state parameter of different task.
The executing state parameter of the different task described in the present embodiment should have the parameter characterizing different task, also will have the parameter characterizing executing state.Wherein, usually can immobilize after determining at first for the parameter characterizing described different task, namely different task has corresponding different parameters; Parameter for characterizing described executing state can for continually varying numerical value, and also can be two numerical value or two letters, concrete the present embodiment be restricted this.Wherein, described continually varying numerical value or described two numerical value or two letters can be used for characterizing terminal the need of execution new task.
103, according to the executing state parameter in heartbeat response packet, the task that server is to be issued is determined.
Terminal is after receiving the heartbeat response packet that issues of server response heartbeat message, according to the executing state parameter of the different task of carrying in described heartbeat response packet, judge the task that server is to be issued, then send task to be issued from heartbeat message so that server treats responding from heartbeat message of issuing of task in time.In the process judging the task that server is to be issued, task to be issued can be judged according to the situation of change of the executing state parameter of different task, also can judge task to be issued according to specific numerical value or letter, concrete the present embodiment is not restricted this.
104, periodically send task corresponding to be issued from heartbeat message so that the corresponding task that reception server issues.
Step 104 be determine in step 103 server terminal after issuing of task start to server send corresponding task to be issued from heartbeat message, mentioned here is can be consistent with main heartbeat message message format from heartbeat message in itself, only main heartbeat message not only plays the object keeping terminal presence, also assures that server can respond to main heartbeat message at any time, issue heartbeat response packet to terminal in time.Then be when server has task to need to be handed down to terminal from the object of heartbeat message, terminal can send in time correspondence task to be issued from heartbeat message, server can be responded to from heartbeat message in time, when Deterministic service device issues task, there will not be delay phenomenon.
Server issues in the process of task actual, might not be at every turn respond and issue task receiving carrying out immediately after heartbeat message that terminal sends, if terminal only sends once from heartbeat message, probably make server cannot respond from heartbeat message.Therefore, at server to before responding from heartbeat message, terminal is wanted periodically to send from heartbeat message to server, Deterministic service device can at needs to when responding from heartbeat message, receive that terminal sends in time from heartbeat message, thus to issue from task corresponding to heartbeat message to terminal.
In the present embodiment indication main heartbeat message and from heartbeat message, its form can be Internet protocol message (Internet Protocol message, be called for short IP message), transmission control protocol message (Transmission Control Protocol message, be called for short TCP message), HTTP message (Hypertext transfer protocol message, be called for short HTTP message), user datagram protocol message (User Datagram Protocol message, be called for short UDP message) etc., the form of the present embodiment to heartbeat message is not restricted.
The method of the transmission heartbeat message that the embodiment of the present invention provides, periodically main heartbeat message can be sent to server, to obtain the heartbeat response packet carrying the executing state parameter of different task, thus determine corresponding task to be issued according to this executing state parameter, and send it from heartbeat message, so that the corresponding task that reception server issues.Compared with prior art, the embodiment of the present invention can when only having new task to perform just send for task response from heartbeat message, effectively can not only reduce the quantity without sending heartbeat message under task status, but also do not affect the timely response of task and issue.
Further, as to the refinement of above-described embodiment and expansion, the executing state parameter of the different task that in above-mentioned steps 103, heartbeat response packet carries can present with the form of mapping table, according to the executing state parameter in mapping table, terminal determines whether its mapping of task is the task that server is to be issued.
In implementation process, different tasks is to having different ID or other marks, and executing state parameter can corresponding key value, such as character, a numeral etc., and each task and corresponding executing state parameter map one by one.The mapping table of respective task and current executing state parameter is all preserved in terminal and server, server is when there being new task to issue, the executing state parameter of corresponding task in mapping table can be revised, issue the heartbeat response packet including mapping table after amendment to terminal.Terminal is after receiving heartbeat response packet, the mapping table preserve self and the amended mapping table of server are compared, when the executing state parameter of the several task of discovery certain or certain changes, terminal determines that the task of these executing state Parameters variation is the new task that server is to be issued.Immediately, terminal to server send these business from heartbeat message so that server responding from heartbeat message and issuing new task these tasks.
Exemplary, in different tasks, mark corresponding to switch change task can be decided to be the mark that mark corresponding to Switch, scan task can be decided to be Scan, strategy change task corresponding can be decided to be Strategy etc.; Executing state parameter can according to Arabic numerals 1,2,3,4 ... characterize.For scan task, when not having new task to perform, the executing state of the scan task Scan in the mapping table that present terminal is preserved is 1, when there being new scan task, the executing state of the scan task Scan in the mapping table that server issues is 2, terminal have received mapping table that server issues and compares with the mapping table that this locality is preserved, to determine and after performing new scan task, the mapping table that can send server carries out this locality and preserves, the executing state of the scan task Scan in the mapping table that terminal is now preserved just becomes 2, the mapping table sent for next time and server is compared.And so forth, after terminal performs new scan task again, the executing state of its scan task Scan can become 3,4,5,6 successively ... etc..Above-mentioned just for scan task, same mode, also the task that switch change task, strategy change task, Run Script task etc. are different can be performed, these tasks can single execution also can executed in parallel, this depends in the mapping table that server issues has the executing state parameter of how many tasks to there occurs change.
Optionally, also the executing state parameter of different task can be represented in the mode of state flag bit, exemplary, described state flag bit can be set as T (True) and F (False), T representative has tasks carrying, and F represents without tasks carrying.Here it should be noted that, the mode representing executing state parameter with state flag bit T and F does not need terminal to carry out preservation and follow-up comparison to the heartbeat response packet carrying execution status of task parameter, this mode only needs the state flag bit of the executing state parameter by reading different task after receiving heartbeat response packet at every turn, if the state flag bit of task is T, then illustrate that this task is the task that server is to be issued, if the state flag bit of task is F, then illustrate that this task is not the task that server is to be issued.Or as the optional mode of another kind, flag bit also can represent by 0 and 1.Wherein, 0 meaning characterized corresponds to above-mentioned F, represents without tasks carrying; 1 meaning characterized corresponds to above-mentioned T, and representative has tasks carrying.
Above-mentioned example is for a station terminal, in like manner, for multiple stage terminal, can add new parameter in the mapping table, namely represent the parameter of different terminals.The parameter of GC group connector can be IP address, also can by some algorithm (as hash algorithm) by server-assignment to terminal mark that can mutually distinguish.Just contain the parameter of GC group connector in such mapping table respectively, represent the parameter of different task and represent the parameter of different task executing state, between these three kinds of parameters, there are mapping relations.Or the mark of a GC group connector also can be added in the parameter representing different task.Exemplary, the parameter of GC group connector can be set successively by Client1, Client2, Client3, Client4 etc., can be reduced to C1, C2, C3, C4 etc.Terminal C1 can corresponding switch change task Switch, strategy change task Strategy, scan task Scan etc., terminal C2, C3, C4 etc. also can corresponding switch change task Switch, strategy change task Strategy, scan task Scan etc., or in the parameter representing different task, add mark and Switch-C1, Strategy-C1, Scan-C1 etc. of a GC group connector, Switch-C2, Strategy-C2, Scan-C2 etc.The different task representing that different terminals is corresponding can both be known by different mapping modes, and the executing state of respective task.The projected forms of concrete the present embodiment to mapping table is not restricted.
Carry out, in the process of information interaction, multiple situation to occur in terminal and server.Such as, when terminal due to artificial or failure cause disconnects from network connection state time, revise the heartbeat response packet after task status in server and may not send to terminal, and when terminal connects into network again, terminal may not need to perform the task in this amended heartbeat response packet.The heartbeat response packet that when being at this moment just necessary to disconnect terminal, server had been revised carries out aftertreatment.Therefore when terminal is in first time access network, receive the useless heartbeat response packet that server issues, optionally, before execution step 101, namely before terminal to server periodically sends main heartbeat message, can first and server carry out the initial synchronization of heartbeat response packet.The initial synchronization of described heartbeat response packet, can comprise the mapping table that mapping table that this locality preserves by server preserves according to terminal and carry out initial synchronization, make the task status in respective mapping table consistent; Also terminal and server can be comprised by the layout initial synchronization of respective mapping table.
Above-mentioned terminal First Contact Connections enters network and not only refers to terminal again connect into network after network interruption is opened, but also refers to the new terminal first connection installed and enter network.No matter terminal in which way First Contact Connections enters network, the initial synchronization that server and terminal carry out heartbeat response packet can ensure that terminal receives up-to-date heartbeat response packet, performs up-to-date task, avoids the task of terminal execution error.
Step 104 periodically send corresponding wait issuing of task after heartbeat message, terminal finally can receive the corresponding task that server issues, concrete reception opportunity and server issue and can respond main heartbeat message and to issue opportunity of heartbeat response packet similar by the server as described above-mentioned steps 102 from opportunity of the corresponding task of heartbeat message, repeat no more herein.
After terminal receives the task corresponding from heartbeat message that server issues, send and reach from the object of heartbeat message.Therefore, optionally, the step from heartbeat message stopping sending corresponding task can be performed after step 104.In implementation process, can select to stop immediately after receiving the task that server issues to send corresponding from heartbeat message, also can select in the certain hour after receiving the task that server issues, stop sending corresponding from heartbeat message after again not receiving new task.
Here it should be noted that, stop sending the step from heartbeat message of corresponding task and both can appear at same execution mode with the step that server carries out the initial synchronization of heartbeat response packet, also can individually occur in one embodiment.Role is all identical in various embodiments for they.
Carry out there will be various situation in the detailed process of information interaction in terminal and server.Such as, when all tasks are all when sending from heartbeat message to server, main heartbeat message does not just have concrete effect, therefore just can select in this case to stop sending main heartbeat message.Once terminal stop send any one task from heartbeat message, namely when terminal stop send at least one task from heartbeat message time, restore cycle property should send main heartbeat message to server immediately, for the heartbeat response packet carrying different task executing state parameter that reception server at any time issues, when avoiding new task to issue, end delay sends corresponding to heartbeat message.Aforesaid operations can ensure that terminal sends the quantity of heartbeat message and is in minimum state all the time, and does not affect server to the response of task with issue.
The embodiment of the present invention, before periodically sending main heartbeat message to server, is carried out the initial synchronization of heartbeat response packet with server, be ensure that terminal receives up-to-date heartbeat response packet, avoids terminal to receive and the task of execution error.Meanwhile, main heartbeat message transmission and stop mechanism again the quantity forwarded of heartbeat message being controlled all the time at minimum state.
Further, as the realization to said method, the embodiment of the present invention additionally provides a kind of device sending heartbeat message, this device can be arranged in terminal, also and data interaction relation can be had between terminal, in order to realize the method shown in different execution modes that above-described embodiment provides independent of terminal.As shown in Figure 2, this device comprises: transmitting element 21, receiving element 22 and determining unit 23, wherein,
