Description

Method and device for processing concurrent requests by single TCP (Transmission control protocol) connection

Technical Field

The application belongs to the technical field of computer communication, and particularly relates to a method and a device for processing concurrent requests through single TCP connection.

Background

In prior art products, communication is indispensable. Among them, TCP is a common communication method. In a real scene, most of the concurrent communication needs to be realized by establishing a plurality of TCP connections.

In a scenario, a connection between a server and a client can only be created when the client initiates the connection for the first time, and once the connection is broken, no data communication can be performed between the server and the client.

In the scenario where only a single TCP connection exists, if a server or a client needs to concurrently send a request to another end, the prior art temporarily stores the request tasks in a certain storage queue, and then the unique TCP connection sequentially takes out the request tasks from the storage queue and sends the request to the other end.

In the prior art, the concurrent request in the true sense can not be realized through a single TCP connection. The request tasks are circularly taken out from the queue and then requested in a mode of temporarily storing the request tasks in the queue, and data in a request result of the mode has certain time delay. When a large number of concurrent tasks exist, if the request is made in a queue temporary storage mode, the queue is too large, and a large amount of memory space is occupied.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, fig. 1 is a flowchart illustrating a method for processing a concurrent request by a single TCP connection according to an exemplary embodiment, where the method for processing a concurrent request by a single TCP connection includes the following steps:

step S101, acquiring a request for establishing TCP connection, which is sent by a client for the first time;

step S102, establishing a TCP connection according to the request of the TCP connection;

step S103, according to the TCP connection, the TCP connection is divided into at least two virtual connections, and the virtual connections are used for complete communication;

step S104, receiving a request task sent by a client, and distributing the virtual connection to the request task by a first connection scheduler so as to complete the request task through the virtual connection.

As is known, the tcp (transmission Control protocol), a transport Control protocol, is a connection-oriented, reliable transport layer communication protocol based on byte streams, and is defined by RFC 793 of IETF. TCP is intended to accommodate layered protocol hierarchies that support multiple network applications. Reliable communication services are provided by means of TCP between pairs of processes in host computers connected to different but interconnected computer communication networks. TCP assumes that it can obtain simple, possibly unreliable, datagram service from lower level protocols. In principle, TCP should be able to operate over a variety of communication systems connected from hard wire to packet switched or circuit switched networks.

Specifically, in the TCP establishing process, the TCP established for the first time is a real TCP connection, the client initiates a request for establishing the TCP connection to the server, the server receives the request for establishing the TCP connection sent by the client for the first time, and the server confirms the request for establishing the TCP connection and returns a response message to the client; the client sends a confirmation message to the server to establish TCP connection with the server. After which this real TCP connection is split into a number of virtual connections available for full communication and these virtual connections are managed by the connection scheduler. At this point there is only one real TCP connection, although there are many virtual connections. When a client initiates a request task to a server, the request task first reaches a connection scheduler, the connection scheduler allocates the split virtual connection to the request task, and then the virtual connection is used for communication.

It can be understood that, in the method for processing concurrent requests by a single TCP connection provided by the present application, a request for establishing a TCP connection, which is sent by a client for the first time, is obtained; establishing a TCP connection according to the request of the TCP connection; according to the TCP connection, the TCP connection is divided into at least two virtual connections, and the virtual connections are used for complete communication; and receiving a request task sent by a client, and distributing the virtual connection to the request task by a first connection scheduler so as to complete the request task through the virtual connection. The concurrent requests are processed under the single TCP connection, other storage parts do not need to be used for temporarily storing the requests, other components used in the requests are simplified, the problem that the space occupied by a memory is too large due to the fact that multi-request tasks are processed under the single TCP connection is solved, and the concurrent processing under the single TCP connection is truly realized.

As a further improvement of the above method, in some embodiments, according to the TCP connection, the splitting of the TCP connection into at least two virtual connections, the virtual connections being used for complete communication, includes:

TCP is a transport layer protocol in the internet that uses a three-way handshake protocol to establish a connection. After the active side sends out the SYN connection request, the opposite side waits to answer SYN + ACK, and finally ACK confirmation is carried out on the SYN of the opposite side. This method of establishing a connection prevents the generation of a false connection, and the flow control protocol used by TCP is a sliding window protocol of variable size. According to the method and the device, whether the TCP connection is established between the client and the server is judged, and the virtual connection is segmented according to the judgment result, so that the transmission stability is ensured.

As a further improvement of the above method, in some embodiments, receiving a request task sent by a client, and allocating, by a first connection scheduler, the virtual connection to the request task so as to complete the task through the virtual connection includes:

According to the technical scheme, the connection scheduler is responsible for managing and distributing virtual connection, and the problems that in the prior art, when a large number of concurrent tasks exist, if a request is made in a queue temporary storage mode, a queue is too large and occupies a large amount of memory space are solved.

In some embodiments, after receiving a request task sent by a client, the first connection scheduler assigns the virtual connection to the request task, so as to complete communication between the client and a server through the virtual connection, the method further includes:

judging whether the request task is completed;

wherein the requesting task may be one or more.

It can be understood that, when the connection needs to be closed, firstly, whether the request task is completed is judged; disconnecting the TCP connection with the server when the request task is determined to be completed; that is, as long as the real TCP connection is closed, the cut virtual connection will be automatically closed; upon determining that the request task is not complete, the client maintains communication with the server over the affiliated virtual connection.
