Fifth embodiment of the invention provides a kind of method for asking addressing between distributed system process, and this method utilizes
DNS Protocol finds target process IP address, and information on services caused by DNS cache is overcome to update not in time and DNS
The problem of pressure of single-point inquiry, more particularly on PAAS (platform services) platform;When using micro services framework, solve
The problem of how being cooperated between micro services process.
DNS (domain name system, Domain Name System) is a kind of computer and networks being organized into domain hierarchy structure
Service naming system, it for TCP (transmission control protocol, Transmission Control Protocol)/IP (network it
Between the agreement that interconnects, Internet Protocol) network, the service that it is provided is for being converted to host name and domain name
The work of IP address.
DNS query is parsed in a variety of ways.Client computer can also obtain sometimes by using from former inquiry
Cache information reply inquiry on the spot, then dns server can be used the resource record information cache of its own come response inquiry,
Requesting clients can be represented to inquire or contact other dns servers, to parse the title completely, and be then back to response
Client computer, this process are known as recurrence.
It, can be by DNS entry in visitor in order to reduce the access pressure to dns server but since DNS Protocol is when formulating
Family end is cached, however in distributed environment, especially in the environment of PAAS, provide the IP address of the target process of service
It can generally change with restarting for service processes.
It is the existing stage, all default in the operating system of various mainstreams to realize DNS Protocol stack, the exploitation language of mainstream
Speech is also all supported by way of DNS query, to obtain the IP address information of destination service;And in a distributed system, due to
Can have the process developed using various development languages is had so being completed the inquiry of target service address using DNS Protocol
Very strong applicability.
Therefore, will provide one kind for this problem in the present embodiment can be such that service caller quick sensing service carries
The variation of donor IP, and can guarantee high-frequency access dns server Query Information will not occur, and to entire DNS query system
The case where system causes to impact, leads to its fluctuation of service occurs.
In distributed structure/architecture, if the process where ISP is restarted on new host, IP address can be sent out
Changing, and the purpose of the embodiment of the present invention is:It solves after service IP address variation, service caller energy quick sensing arrives this
A variation, and ensure the efficient of interprocess communication, the stabilization of system operation, and various development languages can be supported to develop as possible
Program, service addressing can be carried out using the method.Therefore, it asks to seek between the distributed system process of the embodiment of the present invention
The method of location is as follows, and this method is realized by three components, i.e. service registration component, information on services registration center component and service
Enquiring component, setting signal as shown in fig. 7, be described separately below.
(1) service registration component is arranged in ISP's host computer side.
Service registration assembly operating host where service provider monitors the service that ISP's process is provided,
Service registration component requires ISP's process in issuing service, and the information of service is write in a local file, this
Sample service registration component can perceive the information on services that service offer process is provided by the variation of file content.
The effect that this component can generate is as follows:It is run using single process, does not interfere with ISP's operation, it can be with
Realize Fault Isolation;The interaction of log-on message is carried out using file, need not use individual SDK, there is very strong usability,
It can support the program of various development language exploitations.
(2) information on services registration center component is arranged in service register center.
Information on services registration center component is the component for centrally stored information on services, using cluster mode, service note
After the information of the volume component service that monitoring process provides being collected into, the progress of information on services registration center can be will send information to
It preserves.
The effect that this component can generate is as follows:Reduce the pressure of consumer end storage all information;It can quick more new demand servicing
State, and can realize the function that change is notified to consumer end in time.
(3) service-seeking component is arranged in service consumer host computer side.
In same host, service caller can pass through for service-seeking component and service caller (i.e. service consumer)
DNS Protocol and service-seeking component interaction obtain the information on services that ISP is registered.In order to operating system and exploitation
The DNS Protocol interaction of language acquiescence, these can use DNS A records (only supporting to pass through domain Name acquisition IP address), because
In micro services framework, when micro services process is restarted, the IP address of host (virtual machine) can change where general micro services, but it takes
It is engaged in what port substantially changed, so the format energy meet demand recorded using DNS A, and have maximum adaptability.
The effect that this component can generate is as follows:It is interacted, need not be used individual with service consumer using DNS Protocol
SDK has very strong usability, can support the program of various development language exploitations;It is deployed in identical master with service consumer
On machine, for inquiry request not by network transmission, query performance is high;Using the information of own cache, response association requests can be reduced
With the frequency of interaction of information on services registration center component, it is conducive to ensure the stable operation of information on services registration center component;It is only slow
The required information on services of this service consumer is deposited, consumption system resource is few.
The general steps of the above method are as follows:
The first step:The information on services that service registration collect components service provider is provided.
Second step:Service consumer inquires service provider information using DNS Protocol.
Third walks:After information on services changes, modification information notifies service user.
In the following, refining its implementation process for each big step.
The first step may include again:
(1):Service registration component starts as a background process, and beginning listening for a specified local file content is
It is no to change.
(2):After the completion of ISP's process initiation, information on services (Service name and the service release that can be provided
Number) be written in the file of service registration component monitoring, and can periodically be written, relevant timestamp is updated, the heart is played
The effect of jump.
(3):Service registration component can report information on services to service registration after the content for perceiving file changes
Center.
Second step may include again:
(1):The dns server address of host is configured to 127.0.0.1 where service consumer, and those skilled in the art know
Dawn, which is the address interacted with dns server.
(2):Service consumer creates network connection using Service name and port, due to the use of be Service name as domain
Name, can trigger service consumer process and use DNS Protocol, and corresponding IP address is inquired to service-seeking component.
(3):It is inquired if it is first time, service-seeking component can then inquire the related letter of service to service register center
Breath after inquiring the corresponding IP address of service, returns to service consumer, and register and monitor in service register center, if
This service provision information changes, proactive notification service-seeking component.
(4):It is inquired if not first time, then the buffered IP information of ISP of service-seeking component, then
It is directly returned to service consumer.
(5):If inquiring the IP address less than information service, mistake is returned.
(6):When returning to service message person's information, the TTL attributes of DNS can be set to 1 second, such service consumer
Process would not hold the cache entries of information on services for a long time, so that it may to allow service message person quick sensing ISP
Variation.
Third, which walks, may include again:
(1):After service registration collect components to new service registration information, log-on message is reported in service registration
The heart.
(2):Service register center obtains the service-seeking component paid close attention to this information on services according to the login name of service
List.
(3):According to the list that upper step obtains, new service registration information is issued to service-seeking component.
Using the above method provided in an embodiment of the present invention, compared with prior art, there is benefit below:
To development language used by service provider and service consumer, there is no limit;Service consumer is taken by the machine
Business enquiring component inquires information on services, due to not having the step of network transmission, efficiency very high using DNS Protocol;The TTL of DNS is set
It is set to 1 second, can guarantee variation of consumer's energy quick sensing to the information of ISP;Each service consumer takes from the machine
Business enquiring component Query Information, inquiry pressure dissipation will not lead to the inquiry pressure mistake of service register center on each host
It is high.
The key point of the present invention is being used as service query protocol with by DNS, while inquiry pressure being shared to more
On a host, excessive inquiry pressure is avoided, service register center delay machine is caused, while decreased in inquiry information on services
When take, improve the performance of system.In the following, continuing to illustrate to the above process in conjunction with attached drawing.
The sequence diagram for the information on services that Fig. 8 is provided by service registration collect components service provider comprising following step
Suddenly:
