Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

Referring to Fig. 1, a message processing method in Embodiment 1 of the present invention includes:

101. The transparent proxy server obtains the handshake message sent by the client to the WEB server.

It can be understood that the transparent proxy server works in the transparent proxy mode and is located between the client and the WEB server. When the client interacts with the WEB server, the data packets generated will pass through the transparent proxy server. When the client needs to establish a connection with the WEB server, because in the TCP/IP protocol, a three-way handshake is used to establish a connection, during the first handshake, the client will send a handshake message to the WEB server, which is transparent at this time. The proxy server can obtain the handshake message, and the transparent proxy server can identify the destination IP address in the handshake message.

102. When determining that the destination IP address in the handshake message is the preset IP address of the target WEB server, the transparent proxy server determines the target VAS server according to the destination IP address and the corresponding relationship, and the corresponding relationship is the corresponding relationship between the VAS server and the IP address of the target WEB server.

It can be understood that the IP address of the target WEB server is preset in the transparent proxy server, and the transparent proxy server can combine the destination IP address identified from the handshake message with the preset IP address of the target WEB service Compare, when it is judged that the destination IP address is the IP address of the preset target WEB service in the transparent proxy server, the transparent proxy server can The corresponding relationship between the IP addresses of the servers determines the target VAS server.

103. The transparent proxy server constructs a connection between the client, the target VAS server, and the WEB server, and the target VAS server is used to process data interacted between the client and the WEB server message.

It can be understood that the specific VAS server is used to process data packets of one or more types of services, and when the data packets sent by the client to the WEB server are obtained, the transparent proxy server can transfer the The data message is forwarded to the target VAS server, so that the target VAS server performs corresponding value-added service processing on the received data message, and sends it to the WEB server, and the WEB server feeds back to the client The data message may also be processed by the VAS server.

In the embodiment of the present invention,

When the transparent proxy server establishes a connection with the WEB server, it obtains the handshake message sent by the user end to the WEB server, and when the destination IP address of the handshake message is determined to be the IP address of the preset target WEB server, according to the VAS server The corresponding relationship with the IP address of the target WEB server determines the VAS server. Compared with the prior art, the VAS server can be determined without the need for the client to establish a connection with the WEB server, so that the interaction between the client and the WEB server The service packets are processed by the VAS server in a timely manner, improving user experience.

In the message processing method described in Embodiment 1, when it is determined that the destination IP address in the handshake message is the preset IP address of the target WEB server, in practical applications, the IP address of the target WEB server The address may be configured in the transparent proxy server, or obtained by the transparent proxy server. Wherein, the IP address of the target WEB server obtained by the transparent proxy server can be in various ways, specifically as follows:

1. The transparent proxy server acquires the IP address of the target WEB server, specifically: the transparent proxy server determines the domain name of the target WEB server; the transparent proxy server determines the IP address of the target WEB server according to the domain name of the target WEB server The IP address of the target WEB server; the transparent proxy server saves the IP address of the target WEB server.

Referring to Fig. 2, a method for message processing in Embodiment 2 of the present invention includes:

201. The transparent proxy server obtains the handshake message sent by the client to the WEB server.

It can be understood that the transparent proxy server works in a transparent proxy mode, the transparent proxy server is deployed between the client and the WEB server, and is a proxy server that neither the client nor the WEB server perceives, and the client and the WEB server Data packets generated during interaction will pass through the transparent proxy server. For example, in the PCC architecture, the transparent proxy server is PCEF/TDF.

When the client needs to initially establish a connection with the WEB server, the handshake message generated between the client and the WEB server will pass through the transparent proxy server. At this time, the transparent proxy server can obtain the handshake message and identify Get the destination IP address in the handshake message. For example, in the TCP/IP protocol, a three-way handshake is used to establish a connection. During the first handshake, the client will send a synchronous (synchronous, syn) handshake to the WEB server At this time, the transparent proxy server can obtain the syn handshake message, and the transparent proxy server can identify the destination IP address in the syn handshake message.

The client end may be a mobile terminal such as a mobile phone or a tablet computer, or a device capable of accessing the network such as a laptop computer, which is not specifically limited herein.

Optionally, 202 and 203 are also included after 201 in this embodiment.

202. The transparent proxy server determines the domain name of the target WEB server, determines the IP address of the target WEB server according to the domain name of the target WEB server, and saves the IP address of the target WEB server.

It can be understood that, before the client sends a business message to the WEB server, the client usually sends the domain name of the WEB server to the DNS server for domain name resolution. The terminal feedbacks the query result including the IP address of the WEB server. Wherein, the manner in which the transparent proxy server determines the IP address of the target WEB server may specifically be: use the domain name sent by the client as the domain name of the target WEB server, and send the IP address to the client after analyzing the DNS server. The IP address contained in the feedback query result is used as the IP address of the target WEB server; or, the transparent proxy server can also determine the IP address of the target WEB server by recording the number of times the client uses the WEB server domain name to resolve, such as a transparent The proxy server records the first number of resolutions performed by the client using the domain name of the first WEB server and the second number of resolutions performed by the second domain name of the second WEB server. When the first number is greater than or equal to the first When the number of times and the preset ratio of the sum of the second times, the transparent proxy server can use the domain name of the first WEB server as the domain name of the target WEB server, and according to the query result fed back by the DNS server, determine The IP address corresponding to the domain name of the target WEB server is the IP address of the target WEB server.

It should be noted that the preset ratio in this embodiment is 90%, and in practical applications, the preset ratio can be set according to actual needs, which is not specifically limited here.

In this embodiment, after the transparent proxy server determines the domain name of the target WEB server, it determines the IP address of the target WEB server through the query result fed back by the DNS server. The corresponding relationship between the domain name of the domain name and the IP address of the WEB server determines the IP address of the target WEB server, which is not limited here.

The corresponding relationship between the domain name of the WEB server and the IP address of the WEB server may be pre-configured in the transparent proxy server, or the IP address corresponding to the domain name fed back by the transparent proxy server through the domain name and DNS Constructed, the details are not limited here.

203. The transparent proxy server acquires the correspondence between the VAS server and the IP address of the target WEB server.

It can be understood that the transparent proxy server can generate the corresponding relationship by sampling and detecting the data packets sent from the client to the target WEB server, specifically: the transparent proxy server passes Deep Packet Inspection (Deep Packet Inspection , DPI) analyze the destination IP address in the sampling data message, i.e. the IP address of the target WEB server, and track and record the VAS server through which the data message passes, the transparent proxy server according to the IP address of the target WEB server Generate the corresponding relationship with the VAS server through which the data message passes, and save the corresponding relationship.

It should be noted that the corresponding relationship may be obtained by the transparent proxy server, or may be pre-configured in the transparent proxy server after other devices obtain the corresponding relationship, which is not specifically limited here.

The VAS server is used to process specific types of data packets, such as virus filtering, page adaptation, video optimization, etc., which are not limited here.

The client sends data packets to the WEB server through Transmission Control Protocol (Transmission Control Protocol, TCP) or other protocols, which are not limited here.

204. The transparent proxy server judges whether the destination IP address in the handshake message is the preset IP address of the target WEB server, if not, execute step 205, and if yes, execute step 206.

The transparent proxy server can resolve the destination IP address in the handshake message, and compare the resolved destination IP address with the IP address of the target WEB server, thereby judging the destination IP address in the target data message. Whether the address is the IP address of the target WEB server.

205. The transparent proxy server establishes a connection between the client and the WEB server.

When the transparent proxy server determines that the destination IP address in the target data packet is not the IP address of the target WEB server, the transparent proxy server establishes a connection between the client and the WEB server.

206. The transparent proxy server determines a target VAS server according to the destination IP address and a corresponding relationship, where the corresponding relationship is a corresponding relationship between the VAS server and the IP address of the target WEB server.

When the transparent proxy server determines that the destination IP address is the IP address of the target WEB server, the target VAS server is determined according to the correspondence between the VAS server and the IP address of the target WEB server.

207. The transparent proxy server constructs a connection between the client, the VAS server, and the target WEB server, and the target VAS server is used to process data interacted between the client and the WEB server message.

It can be understood that the VAS server can provide value-added service processing for data packets of a specific business type. For example, the video optimization server is used to process data packets whose business type is a video service. In Hypertext transfer protocol (Hypertext transfer protocol, HTTP ), the content type of the video service request report includes: video/mp4, video/x-flv, video/x-f4v, etc.; the page adaptation server is used to process data packets whose service type is a page adaptation service, In the HTTP protocol, the content types of the page adaptation data message include: text/html, application/vnd.wap.xhtml, application/xhtml+xml, ext/vnd.wap.wml, application/vnd.wap. wmlc, image/jpeg, image/gif, image/png, etc.; the content insertion server is used to process the data message whose service type is the content insertion service. In the HTTP protocol, the content type of the content insertion data message includes: text /html, application/vnd.wap.xhtml, application/xhtml+xml, etc.

It should be noted that the VAS server can process one or more types of data packets at the same time, for example, the VAS server can process video data packets and page adaptation data packets at the same time, which is not limited here.

Include in the described transparent proxy server the port that is used for connecting with client end, the port that is used for connecting with VAS server and the port that is used for connecting with WEB server, after determining VAS server according to handshake message, described transparent proxy server can be according to set A communication channel is established between the port connected to the client end and the port connected to the VAS server, thereby realizing the connection between the client end, the target VAS server and the target WEB server. After the transparent proxy server establishes the connection between the client and the VAS server, the target VAS server can process the data that the target VAS server uses to process the interaction between the client and the WEB server message.

In the embodiment of the present invention, the transparent proxy server uses the domain name whose frequency of domain name resolution is greater than or equal to 90% as the domain name of the target WEB server, and then can determine the target WEB server according to the domain name of the target WEB server That is to say, the client uses the IP address of the target WEB server frequently, so according to the correspondence between the IP address of the target server and the VAS server, the success rate of determining the target VAS server can be increased.

2. The transparent proxy server obtains the IP address of the target WEB server, specifically: the transparent proxy server determines the first number and sending number of the first data message sent by the client to the WEB server The second number of times of the second data message, the first number is greater than the second number of times, the first data message includes the first destination IP address, and the second data message includes the second destination IP address; if When the first number is greater than or equal to the preset ratio of the sum of the first number and the second number, it is determined that the first destination IP address is the IP address of the target WEB server; the transparent proxy The server saves the IP address of the target WEB server.

Referring to FIG. 3, a message processing method provided by Embodiment 3 of the present invention includes:

301. The transparent proxy server obtains the handshake message sent from the client to the WEB server.

It can be understood that the transparent proxy server works in a transparent proxy mode, the transparent proxy server is deployed between the client and the WEB server, and is a proxy server that neither the client nor the WEB server perceives, and the client and the WEB server Data packets generated during interaction will pass through the transparent proxy server. For example, in the PCC architecture, the transparent proxy server is PCEF/TDF.

When the client needs to initially establish a connection with the WEB server, the handshake message generated between the client and the WEB server will pass through the transparent proxy server. At this time, the transparent proxy server can obtain the handshake message and identify Get the destination IP address in the handshake message. For example, in the TCP/IP protocol, a three-way handshake is used to establish a connection. During the first handshake, the client will send a synchronous (synchronous, syn) handshake to the WEB server At this time, the transparent proxy server can obtain the syn handshake message, and the transparent proxy server can identify the destination IP address in the syn handshake message.

The client end may be a mobile terminal such as a mobile phone or a tablet computer, or a device capable of accessing the network such as a laptop computer, which is not specifically limited herein.
