Therefore, many network device manufacturers are beginning to research how to comply with the non-standard network protocol stack and the Linux network protocol stack in the Linux operating system to meet the expansion requirement of the network application.

And thirdly, determining a target network protocol stack according to the indication information of the network application. The network application realizes the calling of the target network protocol stack by adapting the uniform interface function, and the method can realize the switching between the nonstandard network protocol stack and the Linux network protocol stack only by adjusting the socket interface or using a new uniform interface. The openness of network applications suffers.
Therefore, how to simply and efficiently realize that the extension requirement of the network application is met in the Linux operating system is a technical problem to be solved urgently.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The system architecture and the service scenario described in the embodiment of the present invention are for more clearly illustrating the technical solution of the embodiment of the present invention, and do not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by those skilled in the art that the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems along with the evolution of the system architecture and the appearance of a new service scenario.
The above method is described in detail with reference to specific examples.
In the embodiment of the invention, the network application can complete the network function only through a network protocol stack running in an operating system such as Linux and the like, the network application completes the network message transceiving and the network function control by calling a socket interface (a network function interface defined by a standard C library, wherein the socket interface comprises a plurality of functions such as socket (), bin (), list (), recvfrom (), sendto () and the like, and the socket docking interface of the network protocol stack is docked with the socket interface to realize the function of the socket interface. The socket interface can only be connected with the socket interface of one network protocol stack, so that when the network equipment such as a router/switch and the like has both a nonstandard network protocol stack and a Linux network protocol stack, the nonstandard network protocol stack and the Linux network protocol stack need to coexist to ensure that the expansion requirement of the network application can directly run on the network equipment such as the router/switch and the like
An embodiment of the present invention provides a method for processing a request, as shown in fig. 1, where the method includes:
In the embodiment of the invention, before the network application needs to send the call request to the network protocol stack, the network application calls the socket interface, and the socket interface calls the socket docking interface of the network protocol stack so as to send the call request to the network protocol stack. The socket docking interface of the network protocol stack is an interface used by the network protocol stack for docking with the socket interface. Socket docking interfaces of the network protocol stack correspond to socket interfaces one to one. On the Linux operating system, the network protocol stack must register the socket docking interface of the network protocol stack with the Linux system call table. When the network application calls the socket interface, the Linux operating system finds the socket docking interface corresponding to the network protocol stack through the Linux system call table and calls the socket docking interface.
In the embodiment of the invention, due to the expansion requirement of the network application, part of the network application can directly use the Linux network protocol stack, but part of the network application needs to use the nonstandard network protocol stack, so that the nonstandard network protocol stack and the Linux network protocol stack exist in the Linux operating system at the same time.
Optionally, the call request sent by the network application is received from a default socket docking interface, and may be the call request sent by the network application through calling a socket interface of the Linux operating system, and received from a socket docking interface of the Linux network protocol stack.
Preferably, the receiving, from the default socket docking interface, a call request sent by the web application includes:
and receiving the call request sent by the network application through calling the socket interface of the Linux operating system from the socket docking interface of the nonstandard network protocol stack.
In the embodiment of the invention, the Linux operating system is started, the nonstandard network protocol stack is initialized, the socket interface of the nonstandard network protocol stack is in butt joint with the socket interface of the Linux operating system, and the proc file is created. And the Linux network protocol stack completes initialization, and the socket docking interface of the Linux network protocol stack is not docked with the socket interface because the nonstandard network protocol stack is already docked with the socket interface. To ensure that the socket interface only interfaces with one network protocol stack. Therefore, the socket interface does not need to be changed or adjusted. As shown in fig. 2, an embodiment of the present invention provides a schematic diagram of a connection relationship between a non-standard network protocol stack and a Linux network protocol stack and a socket interface.
In the embodiment of the invention, if the network application needs to use the non-standard network protocol stack, the network application acquires the unique thread ID of the network application from the Linux operating system and writes the thread ID into a proc file created by the non-standard network protocol stack, wherein the proc file is a file supported by the Linux operating system and can be accessed by both the network application and the network protocol stack. Through the file, the network application can issue control information to the network protocol stack. The thread ID is a unique ID assigned by the Linux operating system to each network application. The nonstandard network protocol stack records the thread ID into a user thread ID table, wherein the user thread ID table records the thread IDs of all network applications needing to use the nonstandard network protocol stack.
In an embodiment of the present invention, before receiving, from a default socket docking interface, a call request sent by a web application, the method further includes:
after the network application is started, writing the thread ID of the network application, which is acquired by the network application from a Linux operating system, into a proc file created by a non-standard network protocol stack;
and the nonstandard network protocol stack records the thread ID into a user thread ID table, wherein the user thread ID table records the thread IDs of all network applications needing to use the nonstandard network protocol stack.
Preferably, before the thread ID of the web application acquired by the web application from the Linux operating system after the web application is started is written into a proc file created by a non-standard network protocol stack, the method further includes:
and docking the socket docking interface of the non-standard network protocol stack with the socket interface of the Linux operating system, and creating a proc file.
102, acquiring a thread ID of the network application from a Linux operating system, and judging whether a user thread ID table contains the thread ID, if so, processing the calling request; if not, calling a socket docking interface of the Linux network protocol stack to enable the Linux network protocol stack to process the calling request. The Linux network protocol stack is a network protocol stack carried by a Linux operating system, and is suitable for network application, such as NETCONF. The nonstandard network protocol stack is mainly a network protocol stack which is customized and developed by network equipment manufacturers such as a router/a switch and the like according to the characteristics of the network protocol stack, and compared with a Linux network protocol stack with a Linux operating system, the nonstandard network protocol stack has higher performance and lower resource consumption. The nonstandard network protocol stack works in a Linux operating system, and the nonstandard network protocol stack is used by the expansion requirement of network application, such as a routing protocol.
For example, a Linux operating system is started, a nonstandard network protocol stack is initialized, a socket interface of the nonstandard network protocol stack is connected with a socket interface of the Linux operating system, and a proc file is created. And the Linux network protocol stack completes initialization, and a socket docking interface of the Linux network protocol stack is not docked with the socket interface.
When a certain network application is started and the network application needs to use a non-standard network protocol stack, the network application acquires a unique thread ID of the network application from a Linux operating system and writes the thread ID into a proc file created by the non-standard network protocol stack. The nonstandard network protocol stack responds to the write proc file of the network application and records the thread ID to a user thread ID table of the nonstandard network protocol stack. The network application generates a socket interface call, such as a bind () function call, which calls a socket docking interface of the non-standard network protocol stack, thereby sending a call request to the non-standard network protocol stack. The nonstandard network protocol stack acquires the thread ID of the network application from the Linux operating system according to the call request of the network application, and the thread ID exists in a user thread ID table at the moment, so the call request is processed by the nonstandard network protocol stack.
For example, when a certain network application is started, the network application needs to use a Linux network protocol stack, and a socket interface call, such as a bind () function call, is generated during the running process, and the socket interface calls a socket docking interface of a non-standard network protocol stack, so that a call request is sent to the non-standard network protocol stack. The nonstandard network protocol stack acquires the thread ID of the network application from the Linux operating system according to the call request of the network application, and the nonstandard network protocol stack calls the socket docking interface of the Linux network protocol stack because the thread ID of the network application is not in the user thread ID table of the nonstandard network protocol stack, so that the Linux network protocol stack processes the call request of the network application.
The embodiment of the invention provides a request processing method, which can simultaneously run a nonstandard network protocol stack and a Linux network protocol stack on network equipment such as a router/a switch and the like, network applications can find the applicable network protocol stack according to requirements, all the network applications carry out information interaction with the network protocol stack through the same socket interface, and the Linux network protocol stack does not need to be improved. The method of the embodiment of the invention enhances the openness and compatibility of the network equipment and ensures that the expansion requirement of the network application can be directly operated on the network equipment such as a router/switch and the like.
