Embodiment 1

[0050] Such as figure 1 As shown, it is a schematic diagram of networking of a network traffic caching system provided in Embodiment 1 of the present application. The network traffic caching system can be applied in an operator network environment, and its main components include a core router, an SDN switch, and a transparent proxy caching server. WEB website server, Deep Packet Inspection (Deep Packet Inspection, DPI) traffic analyzer, SDN controller, cache log analysis server and management platform; wherein,

[0051] In addition to the basic routing function, the core router also has the policy routing function, that is, when forwarding the IP data packet carrying the web page request message, it matches the IP data packet with the pre-configured policy routing, and if it matches, the IP data packet The packet is forwarded to the SDN switch; if it does not match, the IP data packet is forwarded to the WEB server. Here, the pre-configured policy routing only matches IP dat...

Embodiment 2

[0066] Aiming at the above-mentioned network traffic caching system, Embodiment 2 of the present application proposes a network traffic caching method, the flow chart of which is as follows figure 2 shown.

[0067] S201: The client initiates a webpage request message.

[0068] Here, the client can click a certain Uniform Resource Locator (Uniform Resource Locator, URL) hyperlink on a hypertext markup language (HyperText MarkupLanguage, HTML) page in the browser or enter a certain URL in the search bar of the browser. After the domain name, a webpage request message is initiated. Wherein, the webpage request message includes source IP address information, domain name information, destination IP address information, destination port number, and the like. Wherein, the destination IP address information may be obtained from the DNS server by calling a domain name system (Domain Name System, DNS) resolution program before the client initiates the web page request message, and th...

Embodiment 3

[0095] Such as image 3 As shown, the flow chart of the network traffic caching method provided in Embodiment 3 of the present application includes the following steps:

[0096] S301: The core router determines the IP data packet carrying the web page request message to be forwarded.

[0097] S302: Match the IP data packet with a pre-configured policy route, wherein the policy route only matches an IP data packet with specified IP address information and carrying a Transmission Control Protocol TCP port number of 80.

[0098] If it matches, the IP packet is forwarded to the software-defined network SDN switch, so that the SDN switch determines the way to respond to the web page request message; wherein, the way to respond to the web page request message is to respond to the web page request message by the Internet WEB website server, or by transparent The proxy cache server responds to the web page request message;

[0099] If not matched, the IP data packet is forwarded to ...

Abstract

The present application relates to the field of network technology, in particular to a network traffic caching system, method and device, which are used to solve the problem that neither the reverse proxy caching scheme nor the transparent proxy caching scheme in the prior art can be effectively applied to the operator's network environment; The network traffic caching method provided by the embodiment of the present application includes: when the core router forwards the IP data packet bearing the web page request message, it matches the IP data packet with the pre-configured policy route; if it matches, then forwards the IP data packet to SDN switch, so that the mode of responding to web page request message is determined by SDN switch; Wherein, the mode of responding to web page request message is to respond to web page request message by WEB website server, or respond to web page request message by transparent proxy cache server; If do not match, then will The IP data packet is forwarded to the WEB website server, so that the WEB website server responds to the webpage request message.

Description

technical field [0001] The present application relates to the field of network technology, and in particular to a network traffic caching system, method and device. Background technique [0002] With the rapid development of computer network technology, a large number of Web cache servers are deployed in the computer network, which effectively speeds up the user's access rate and relieves the processing pressure of the web server (Web Server). [0003] The existing Internet Web cache deployment methods mainly include reverse proxy caching scheme and transparent proxy caching scheme, among which, [0004] Option 1: The reverse proxy caching solution follows the Hyper Text Transfer Protocol (HTTP), and its key technical point is that the domain name system (Domain Name System, DNS) server responds after receiving the domain name resolution request sent by the browser. The IP address of the Web cache server is given to the browser so that the browser and the Web cache server c...
