Detailed Description
For a more complete understanding of the nature and the technical content of the embodiments of the present application, reference should be made to the following detailed description of embodiments of the application, taken in conjunction with the accompanying drawings, which are meant to be illustrative only and not limiting of the embodiments of the application.
The following is an explanation of key terms related to the embodiments of the present application:
HTTP2 (HyperText Transfer Protocol 2.0.0): the hypertext transfer protocol version 2, initially named HTTP 2.0, abbreviated as h2 (encrypted connection based on transport layer security protocol (i.e., TLS) 1.2 or more) or h2c (non-encrypted connection), is the second major version of the HTTP protocol, used on the world wide web.
HTTP2 multiplexing, a characteristic of HTTP2 protocol, namely that when the client sends a message to the server, the client does not need to wait for receiving the response of the last request message and then send the next request message, and can send a plurality of request messages to the back-end server at the same time, and each request message has no dependency relationship and no dependency relationship between response information.
Fig. 1 is a flow chart of a connection multiplexing method provided by an embodiment of the present application, and as shown in fig. 1, the connection multiplexing method provided by the embodiment of the present application includes the following steps:
step 101: and acquiring a request message sent by at least one client to the destination server.
In the embodiment of the application, the client is also called a client, and refers to a program corresponding to a back-end server for providing local service for the client. Except for some locally running applications, which are typically installed on a common client, it is necessary to work with the backend server. In the internet technology, more commonly used clients include web browsers such as those used by the world wide web, email clients when receiving emails, and client software for instant messaging. For various application programs of the client, corresponding back-end servers and service programs are required to provide corresponding services in the network, such as database services, email services and the like, and specific communication connection needs to be established between the client and the back-end servers to ensure the normal operation of the client application programs.
The destination server includes one or more back-end servers, which are one type of computer that operates faster, is more loaded, and is more expensive than a conventional computer. The backend server provides computing or application services for other clients (such as PC, smart phone, ATM, etc. terminals and even large devices such as train systems) in the network. The back-end server has high-speed CPU operation capability, long-time reliable operation, strong I/O external data throughput capability and better expansibility. According to the services provided by the back-end server, the back-end server generally has the capabilities of bearing response service requests, bearing services and guaranteeing services.
The proxy server is an intermediate device in communication connection between the client and the back-end server, and is responsible for forwarding the request message Wen Heying reply information between the client and the back-end server.
In the embodiment of the application, the proxy server can simultaneously receive a plurality of request messages sent by a plurality of clients, wherein the number of the request messages sent by each client is one or more.
As shown in fig. 2, the proxy server can simultaneously receive the request messages A1, A2, A3 sent by the client 1, the request messages B1, B2, B3 sent by the client 2, and the request messages C1, C2, C3 sent by the client 3.
The request message sent by each of the plurality of clients may include multiple types, and as illustrated in fig. 2, the client 1 sends three request messages A1, A2, and A3, where the request messages A1 and A2 are requests for sending an email, and the request message A3 is a request for performing picture processing.
Step 102: and grouping the request messages based on a preset grouping rule, and determining grouping attributes of each group of request messages.
In the embodiment of the application, the preset rule is specifically a rule according to which a plurality of request messages are grouped, the preset rule can be selected into a plurality of forms, and grouping attributes corresponding to all the request messages in the same group of request messages are the same after the request messages are grouped according to the preset rule. According to different preset rules, specific attributes contained in the grouping attributes are different.
In one embodiment, the preset rule specifically groups the plurality of request messages according to the type of the resource of the request message sent by the client, for example, groups the request messages sent by the clients and belonging to the type of receiving and sending e-mails, and groups the request messages sent by the clients and belonging to the type of processing pictures. In this case, the packet attribute is specifically the requested resource type.
Here, if the packet attribute is specifically the requested resource type, the TCP connection corresponding to the packet attribute may be understood as a backend server corresponding to the packet attribute. For example, a set of request messages belonging to the type of e-mail may be sent to a back-end server dedicated to handling e-mail tasks, and a set of request messages belonging to the type of picture processing may be sent to a back-end server dedicated to picture processing tasks.
In another embodiment, the preset rule specifically groups the plurality of request messages according to a level of a priority corresponding to the request message sent by the client, for example, groups the request messages belonging to the first priority sent by each client, and groups the request messages belonging to the second priority sent by each client, where the first priority is higher than the second priority. In this case, the packet attribute is specifically the priority type of the request. Here, if the packet attribute is specifically the priority type of the request, the TCP connection corresponding to the packet attribute may be understood as a backend server corresponding to the packet attribute. For example, the proxy server may send a set of request messages belonging to a first priority to a first backend server and a set of request messages belonging to a second priority to a second backend server, where the processing speed of the first backend server is greater than the processing speed of the second backend server.
In addition, the preset rule can also be to group the request message according to different types of the client, in which case, the grouping attribute is specifically the type of the client; or the preset rule is to group the request message according to the security level of the request message, and the like, and in this case, the grouping attribute is specifically the type of the security level of the request. The embodiment of the application does not specifically limit the preset rules and grouping attributes, and the preset rules and the grouping attributes are several specific rules listed in the embodiment of the application and grouping attributes corresponding to the specific rules, and it can be understood that the preset rules and grouping attributes in the embodiment of the application can also be in other forms.
In fig. 2, after receiving the request messages A1, A2, A3, B1, B2, B3, C1, C2 and C3 sent by the client 1, the client 2 and the client 3, the proxy server groups the 9 requests according to a preset rule to obtain A1 st group of request messages consisting of A1, B2, C3 and A2 nd group of request messages consisting of C1, A3, B1, B3 and C2. Wherein, each request message in the 1 st group request message corresponds to the group attribute 1, and the 2 nd group request message corresponds to the group attribute 2. According to the determined two grouping attributes, the TCP connection corresponding to the two grouping attributes can be determined, and the method can be understood as determining 3 back-end servers corresponding to each group of request messages according to the determined two grouping attributes.
Step 103: and determining available established TCP connections corresponding to each packet attribute according to the packet attribute of each group of request messages, wherein each established TCP connection corresponds to one packet attribute.
In the embodiment of the application, the grouping attribute of each request message included in the same group of request messages is the same, and the grouping attribute is the same, which can be understood that each request message in the same group of request messages corresponds to the same TCP connection, and can also be understood that each message in the same group of request messages corresponds to the same back-end server.
In an alternative embodiment of the present application, the step 103 may be specifically implemented by the following process:
Step 3-1): determining whether TCP connections corresponding to each group of grouping attributes are stored in a connection pool according to the grouping attributes of each group of request messages;
Step 3-2): and if the corresponding TCP connection is stored in the connection pool, acquiring the available established TCP connection from the connection pool.
In order to reduce the number of times of establishing connection with the back-end server, the proxy server can maintain a connection pool, when the connection between the client and the back-end server is disconnected, the corresponding connection between the proxy server and the back-end server is not disconnected, but the proxy server is put into a connection pool maintained by the proxy server, and when a new request message of the client meeting the condition is dispatched to the same back-end server, the proxy server can take out the connection with the back-end server from the maintained connection pool to process the request message.
For the determined grouping attribute corresponding to each group of request messages, the proxy server firstly determines whether TCP connection corresponding to the grouping attribute of the group of request messages exists from a connection pool maintained by the proxy server, and if so, the proxy server can directly utilize the existing TCP connection corresponding to the grouping attribute to send the group of request messages.
In an alternative embodiment of the present application, the step 3-2) may be implemented by:
step 3-2-1): if the corresponding TCP connection is stored in the connection pool, determining whether the bandwidth of the TCP connection does not exceed a bandwidth threshold;
Step 3-2-2): and if the bandwidth threshold is not exceeded, acquiring available established TCP connection from the connection pool.
After determining that the TCP connection corresponding to the packet attribute of each group of request messages exists in the connection pool maintained by the proxy server, the proxy server also needs to judge whether the bandwidth of the TCP connection corresponding to each group of request messages exceeds a bandwidth threshold value, and the step is to realize load balancing, so as to avoid the influence on the processing speed of the request messages or the loss of response information due to overlarge load between the proxy server and the corresponding back-end server.
In an alternative embodiment of the present application, if the available established TCP connection corresponding to the packet attribute cannot be determined, the TCP connection is established with the corresponding backend server.
For the packet attribute corresponding to each group of request messages, if the proxy server cannot determine the available established TCP connection corresponding to the packet attribute, or it may be understood that if the proxy server determines that the TCP connection is not established with the backend server corresponding to the packet attribute, the proxy server needs to first perform an operation of establishing the TCP connection with the backend server corresponding to the packet attribute.
As shown in fig. 2, before sending the 1 st group request message to the server 1, the proxy server needs to confirm whether a TCP connection is established between the proxy server and the server 1, and if not, needs to establish a TCP connection with the server 1 first, and then sends the 1 st group request message. Similarly, before sending the 2 nd group request message to the server 2, the proxy server needs to confirm whether a TCP connection is established between the proxy server and the server 2, and if not, needs to establish a communication connection with the server 2 first, and then sends the 2 nd group request message.
Step 104: based on the connection multiplexing of the available established TCP connection, the request message of each packet attribute is sent to a corresponding back-end server which can realize the partial function of the destination server.
In the embodiment of the application, for each group of request messages, after each group of request messages is required to be encapsulated according to a communication protocol between a proxy server and a back-end server, each encapsulated group of request messages is sent to the back-end server corresponding to the grouping attribute of the group of request messages.
In an alternative embodiment of the present application, a communication protocol between the proxy server and the client, and between the proxy server and the backend server is HTTP2.
In the embodiment of the application, the HTTP2 communication protocol between the proxy server client and the back-end server supports parallel processing of a plurality of request messages and a plurality of response messages, and the request messages have no dependency relationship and the response messages have no dependency relationship.
In an optional embodiment of the present application, the proxy server records a correspondence between the client and the request message, so as to ensure that when receiving the response information of the backend server, the proxy server can determine the corresponding client.
The proxy server not only sends the request message of each grouping attribute to the corresponding back-end server based on the established TCP connection, but also records the connection information between each request message and the client, wherein the connection information can be specifically understood as the corresponding relation between the request message and the client; or the proxy server records the connection information between the request message and the client and the back-end server, and at this time, the connection information can be specifically understood as the corresponding relation between the request message and the client and the back-end server.
After receiving each request message, the back-end server can generate corresponding response based on the specific content of the request message. Based on the record of the connection information, the proxy server firstly determines a request message corresponding to the response information after receiving the response information sent by the back-end server, so as to determine which client needs to be specifically sent with the response information based on the recorded connection information.
For example, after receiving the response information sent by the back-end server 1 or the back-end server 2, the proxy server can determine that the response information is specific to the response information corresponding to the request message, for example, after receiving the response information a11 sent by the back-end server 1, the proxy server determines that the response information a11 is the response information corresponding to the request message A1, and further, based on the recorded client corresponding to the request message A1, the proxy server can determine that the response information a11 needs to be sent to the client 1.
In an alternative embodiment of the present application, the proxy server encapsulates each response message corresponding to each received request message according to a transmission protocol between the proxy server and the client, and then sends each response message to the corresponding client.
In an alternative embodiment of the application, the proxy server maintains a TCP connection with each back-end server in the event that the connection with the client is broken.
Taking the client 1 shown in fig. 2 as an example, after the request messages A1, A2 and A3 sent by the client 1 each receive corresponding response information, the client 1 disconnects from the proxy server, but the TCP connection between the proxy server and the back-end server 1 and the back-end server 2 is not disconnected, and the proxy server still maintains the TCP connection between the proxy server and the back-end server 1 and the back-end server 2in the connection pool. When the client 1 sends a request message to the back-end server 1 or the back-end server 2 again, the proxy server can directly take out the connection with the back-end server 1 or the back-end server 2 from the connection pool and use the connection.
The technical scheme of the embodiment of the application can enable the same connection between the proxy server and the back-end server to be used by a plurality of clients, realize the processing of a plurality of request messages sent by the plurality of clients, realize the multi-to-multi connection multiplexing effect between the plurality of clients and the plurality of back-end servers under the condition that the plurality of clients and the plurality of back-end servers exist simultaneously, remarkably improve the utilization rate of the connection between the proxy server and the server and improve the response speed of the request messages sent by the plurality of clients.
According to the technical scheme, on one hand, the number of connections between the proxy server and the back-end server is guaranteed, the proxy server is prevented from maintaining more TCP connections, and on the other hand, the request message sent to a certain back-end server for processing can be guaranteed to be of one type or only achieve one purpose, so that development, maintenance and upgrading of back-end service are facilitated.
