Preferred embodiment 1

FIG. 8 is a flowchart of processing a page content according to a preferred embodiment 1 of the present invention. As shown in FIG. 8, the following steps may be substantially included:

Step S802: On the forward node of the forward broadcast system network, the page content is captured periodically (or non-periodically), specifically, the hot content may be captured, and the hot content may be determined by using the prior art. Any of the methods in the present invention is not limited thereto.

In order to save bandwidth, the content of the captured hot content can be filtered (for example, the advertisement content is filtered out), and the content is compressed after being compared with the last crawled content.

In step S804, the content package of the hot content can also be distributed by means of a reliable multicast protocol.

In step S806, the multicast content is received at the user side gateway (corresponding to the slave node of the above embodiment).

If the sender compresses the content package, the receiver needs content to decompress and operate.

Step S808, buffering the received content to generate a cache entry.

Step S810, the user terminal initiates an HTTP access request.

Step S812, on the user gateway side, request interception of the user http.

Step S814, after intercepting the http request, performing a query comparison with the cached content item.

Step S816, if the entry requested by the user is stored in the cache, the cached content is directly returned to the user to speed up the user's HTTP access.

Step S818, if the entry requested by the querying user is not stored in the cache, the content resource is requested from the remote content server.

The user terminal is non-perceived throughout the acceleration process and does not require proxy settings for the user terminal.

In the actual communication process, the physical layer of each child node determines whether it is its own data according to a specific situation, and decides whether to send the data to an upper layer for processing or forwarding, that is, a preferred embodiment of the present invention, based on the underlying physical link. It is a feature of the broadcast feature to implement a reliable multicast protocol (Real Time Messaging Protocal, RTMP for short message). The primary node multicasts or broadcasts the message, and all the child nodes can receive it and send it to The application layer caches or forwards the content, which can greatly save bandwidth traffic. If a unicast protocol transmission (such as TCP protocol transmission) is used in the forward broadcast system, it will consume N times of bandwidth traffic (assuming the current primary node) There are N child nodes), and the more child nodes, the higher the bandwidth saving ratio.

The Reliable Multicast Protocol (RTMP) is based on the IGMP multicast protocol and has several implementations:

1) The multicast server and the receiver perform multicast packet acknowledgment to implement reliable multicast transmission; this solution requires a feedback link, and the link error rate requirement is relatively reduced; 2) the multicast server performs the packet content. Redundant algorithm coding, the multicast receiver performs algorithm decoding to combat error and packet loss; this scheme can not require feedback link, but has higher requirements on link error rate.

The reliable multicast protocol module 92 (corresponding to the transmitting module 42 of the above embodiment) implements a reliable multicast protocol based on the characteristics of the broadcast system to achieve bandwidth saving.

The content buffering module 94: decompresses and caches the multicast content, and generates a content item list.

Intercepting the matching module 96 (corresponding to the query module 64 of the above embodiment): intercepting the HTTP request of the user, and comparing the cache entries in the content buffer module, if the accelerated cache resource is identified Exist, immediately return resources to the user to achieve accelerated access.

The above-mentioned technical solution provided by the present invention performs multicast distribution on the hot content that the user terminal needs to access, which greatly saves bandwidth traffic; and combines content caching and http packet interception technology to realize user HTTP access acceleration; meanwhile, the method It is non-aware of the user terminal and avoids intervention in the user terminal settings.
