Abstract
The invention provides a method for implementing fast FailOver in a cluster system. A service progress is identified by using a 32-bit integer. The method is characterized in that a communication protocol carries a service progress identifier; and two parties for communication position a specific position of the service progress according to the identifier, so that a method for sending a service request to a target system is implemented. The method is applied to the cluster system; and when the progress of a server is subjected to abnormal FailOver switching, a new progress of the server can be quickly positioned by a client.
Description
Technical field
The invention belongs to the telecommunication technology field, be particularly related in group system the inside, when the service end process exception withdraws from, when FailOver occuring switching, solve client and how to locate fast the problem of new service end process, and the application of the method in value-added telecom services.
Background technology
At present, telecom operators require service was provided in 7*24 hour to operation system, and making up group system is a well selection.When group system just needed a kind of solution service end process that the FailOver switching occurs, how client located the problem of new service end process fast.
Summary of the invention
The objective of the invention is the problem for service end process in the telecommunications group system and client process communication, when the FailOver switching occurs in the service end process, client realizes the service end process switching by obtain new service end progress information from LIST SERVER.
In order to realize goal of the invention, the technical scheme of employing is as follows:
The integer that a kind of use is one 32 is counted the identification service process, and its principle is to identify by carry service processes in communications protocol, and the both sides of communication identify the particular location of positioning service process according to this.
After the service end process entered service, every interval m second was to the LIST SERVER reporting state information.
LIST SERVER is preserved the mapping relations table of a service processes sign and service processes position information.If LIST SERVER is not all received status report, the information that delete this service processes at n*m in second.
The every interval of client x second is upgraded local mapping table to the mapping relations of the process identification (PID) of LIST SERVER request service and service processes position information.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do simple the introduction to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Figure is the flow chart that the integer of 32 of uses of the present invention is counted the realization FailOver of identification service process.
Embodiment
The enforcement scene of this patent is in a group system, to have two service processes to be deployed in respectively on two physical machines, a LIST SERVER, a client.
Implementing procedure is:
Two service processes (process number is a, and ip is ip_1 and ip_2) every n second to LIST SERVER mode status report.
Client every x second the map information (a:ip_1) to the process identification (PID) of LIST SERVER inquiry service and service end machine.
3. client need to be sent out when request to a, gets access to ip_1 from the mapping table of this locality, sends out request to ip_1.
4. if the machine at ip_1 place is unusual, LIST SERVER after second, is revised mapping relations a:ip_2 at t+n*m.
5. client after second, is revised mapping relations a:ip_2 at t+n*m+x, and follow-up request will send to the machine at ip_2 place
The above only is the specific embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (5)
1. realize quick FailOver in a group system, it is characterized in that using one 32 integer to count the identification service process, carry the service processes sign in communications protocol, the both sides of communication identify the particular location of positioning service process according to this, thereby realize service request is sent to a kind of method of goal systems.
2. integer according to claim 1 32 is counted the service processes sign, and its feature is used for identifying main COS at high 16, and low 16 are used for sign sub-services type, and different sub-services types can be shared a service processes.
3. according to claim 1ly a kind ofly count the method that service processes comes the particular location of positioning service process with integer, it is characterized in that, the client network element need to be safeguarded the mapping table of the particular location of a process identification (PID) and service processes, the tram that will obtain by mapping table service processes when at every turn sending service request to the service end process.
4. the mapping table of the particular location of a kind of process identification (PID) according to claim 3 and service processes is characterized in that, the client network element needs regularly to the mapping relations of LIST SERVER query procedure sign with the particular location of service processes.
5. preserved the mapping table of the particular location of process identification (PID) and service processes on the LIST SERVER according to claim 4, it is characterized in that, the client network element needs regularly to report to LIST SERVER the state information of oneself.
