Description

Method and system for acquiring server IP (Internet protocol) from cross-network segment

Technical Field

The present application relates to the field of internet technologies, and in particular, to a method and a system for acquiring a server IP across network segments.

Background

An IP address (Internet Protocol, IP) is an address of a 32-bit binary number, and theoretically, a calculation result of 2 to the power of 32 has a large address space, and about 40 hundred million possible address combinations exist. According to different bit rules of the network ID and the host ID, the IP address can be divided into an A-type address, a B-type address and a C-type address, wherein the A-type address comprises a 7-bit network ID and a 24-bit host ID, the B-type address comprises a 14-bit network ID and a 16-bit host ID, and the C-type address comprises a 21-bit network ID and an 8-bit host ID. Due to the difference between historical reasons and technical development, the class-A address and the class-B address are almost completely allocated, and in fact, the class-C address can be allocated to various organizations all over the world. Thus, IP addresses are a very important network resource, including Dynamic IP addresses (Dynamic IP) and Static IP addresses (Static IP). A static IP address (fixed IP address) is an IP address that is permanently assigned for use by a computer or network device. Dynamic IP addresses are a way to allocate IP addresses when they need to be used. Usually, a special server or a computer using a dedicated line for accessing the internet uses a fixed IP address and requires a relatively high cost. Because the IP address resource is very limited, most users access the internet by using dynamic IP addresses, for example, computers accessing the internet by Modem, ISDN, ADSL, cable broadband, cell broadband, etc., and an IP address needs to be temporarily allocated each time they access the internet. In some scenarios, the server in the computer room is easy to change IP after power-off restart, and all clients recording the server IP cannot connect to the server at this time, and further system shutdown is caused.

Therefore, it is desirable to provide a method and a system for acquiring a server IP across network segments, which are capable of rapidly acquiring the server IP across network segments in a communicable state by determining live IPs in a local area network and then sequentially sending confirmation requests until a correct IP is acquired, thereby saving resources and improving user experience.

It should be noted that the above description of the inter-segment acquiring server IP system 100 in the same lan is only for convenience of description, and the present application is not limited to the scope of the illustrated embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the principles of the system, which may be combined in any manner or combined with other elements to form a subsystem for use in a field of application in which the method and system described above is practiced. Such variations are within the scope of the present application.

Fig. 2 is an exemplary flow diagram of a method for obtaining a server IP across network segments provided in accordance with some embodiments of the present application. As shown in fig. 2, the process 200 may be implemented by acquiring the server IP system 100 across network segments. In some embodiments, the method 200 for obtaining the IP of the server across network segments may be initiated automatically or by command. The instructions may include system instructions, device instructions, user instructions, action instructions, and the like, or a combination of the several. As an example, the system instruction may be generated by information acquired by a sensor, for example, the client 130 detects information that the server 120 is not connectable, and the like. The user instruction may

At 201, when the client detects that the server is not connectable, a search procedure is started. Operation 201 may be implemented by acquiring a client 130 of a server IP system 100 across network segments. In some embodiments, when the client 130 detects that the server 120 is not connectable, the client 130 may initiate the method 200 of obtaining the server IP across network segments, e.g., initiate a lookup procedure. The search procedure may include searching for the server 120 of the current lan, etc.

At 202, an IP list of the current lan is obtained by the client using an asynchronous PING method. Operation 202 may be implemented by acquiring a client 130 of a server IP system 100 across network segments. For example, when the server 120 restarts changing IP, the client 130 lacks the IP address of the server 120, and in some embodiments, the client 130 may obtain the IP list of the current lan by using an asynchronous PING method (Packet Internet Groper). The Asynchronous PING method may include an Asynchronous Call (Asynchronous Call) without waiting for the return value of the called function and continuing operation. The IP list of the current lan may include IP address information lists of all servers in the server 120 in the same lan. The obtaining of the IP list of the current lan through the client 130 may be implemented by using asynchronous call, and the obtaining of all IP lists that can be PING-connected in the current lan through the client 130.

At 203, the IP list is traversed and UDP information is sent asynchronously by the client. Operation 203 may be implemented by acquiring a client 130 of the server IP system 100 across network segments. In some embodiments, the client 130 may traverse the IP list of the current lan and asynchronously send UDP information to the IP addresses of all servers in the server 120 within the same lan. In some embodiments, the asynchronous transmission may comprise an asynchronous transmission, and client 130 may only transmit UDP information without waiting for a response. The asynchronous sending of UDP information by the client 130 may include sending fixed information by the client 130, which may include information associated with the correct server.

At 204, the associated UDP information is received and specific information is returned through the server-side bootstrapping listening service. Operation 204 may be implemented by acquiring the server 120 of the server IP system 100 across network segments. In some embodiments, the server 120 may self-initiate the listening service, which may receive the associated UDP information when initiated and further return specific information to the client 130.

It should be noted that, the self-initiated snoop service of the server 120 in the operation 204 may be executed before the operation 201, or executed simultaneously with the operation 201, which is not limited in this application, that is, the operations are not in sequence in execution timing, and the above description of the operations of the flow 200 is only an exemplary description of the embodiments of the present application.

At 205, a server IP is determined by the client based on the received specific information. Operation 205 may be implemented by acquiring a client 130 of the server IP system 100 across network segments. In some embodiments, the client 130 may determine the IP of the server 120 according to the received specific information, and the IP of the server 120 may be any server IP of the server 120 in the same lan.

According to some embodiments of the present application, the process 200 may further include establishing a connection between the client and the correct server. The operation may be implemented by acquiring the client 130 and the server 120 of the server IP system 100 across network segments. In some embodiments, the client 130 may obtain the correct server and determine the server IP, and further establish a connection with the correct server. The correct server may include a server that receives the associated UDP information and returns specific information. In some embodiments, when the client 130 determines the server 120IP, the terminating client 130 sends the request message. The termination of sending the request information includes that the client 130 terminates sending information to other servers in the server 120 corresponding to the IP list which is not traversed, and the like. According to some embodiments of the present application, after the server in the server 120 restarts IP replacement, the client 130 may automatically and quickly establish communication with the server through the process 200.

According to some embodiments of the present application, if the received UDP information is not related, the process 200 may further include the server not returning the specific information. The operations may be implemented by obtaining the server 120 and/or the client 130 of the server IP system 100 across network segments. In some embodiments, when the UDP information received by the server 120 is not associated, the server 120 does not return specific information to the client 130, and the client 130 may continue to send the requested information. The request information may include UDP information transmitted by the client 130, and the like. When the UDP information is not associated, the server in the server 120 corresponding to the traversed IP address is not the correct server to which the client 130 needs to connect.

It should be noted that the above description of the process 200 is for convenience only and is not intended to limit the scope of the present application. It will be understood by those skilled in the art that various modifications and changes in form and detail may be made in the functions implementing the above-described processes and operations based on the principles of the present system, in any combination of operations or in combination with other operations constituting sub-processes without departing from the principles. For example, the process 200 may further establish a connection between the client and the correct server. Such variations are within the scope of the present application.

In summary, according to the method and system for acquiring the server IP across network segments in the embodiment of the present application, through determining the live IP in the local area network, and then sequentially sending the confirmation request until the correct IP is acquired, the server IP is quickly acquired across network segments in a communicable state, resources are saved, and user experience is improved.

It is to be noted that the above-described embodiments are merely examples, and the present application is not limited to such examples, but various changes may be made.

It should be noted that, in the present specification, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

Finally, it should be noted that the series of processes described above includes not only processes performed in time series in the order described herein, but also processes performed in parallel or individually, rather than in time series.
