Embodiment Construction

[0049] In order to solve the above problems, the prior art provides a bypass cache implementation solution for BT data download, which is to deploy a cache server between the client and the gateway. The cache server may be a bypass cache server or an intelligent router. The cache server usually needs to have a large storage space and can support the traditional Tracker protocol to realize data cache. Its implementation process is as follows figure 1 shown.

[0050] Wherein, the client requests data to the Tracker server, and the cache server listens to the data request sent by the client; figure 1 shown by the arrow ② in ), so that the client can obtain the target data from the device; if the local cache does not have the target data, the cache server will send a download request to the Tracker server (such as figure 1 As shown by the arrow ① in ), to obtain the address index table of the target data from the Tracker server, and download the target data to the local cache ac...

Abstract

The invention provides a data caching method and a data caching device. The method comprises the following steps: S1, monitoring a data request sent by a client to a Tracker server; S2, parsing out a key value corresponding to target data from the data request; S3, finding out the target data in a local data cache according to the key value; S4, sending a download request to the Tracker server and a DHT network to acquire an address index table corresponding to the target data if the target data is not found out, wherein the address index table includes the download address of the target data; and S5, downloading the target data to the local cache according to the download address in the received address index table. Therefore, more address index tables can be obtained, the download speed is increased, the downloaded data is more comprehensive, the cache service is still not affected even if the Tracker server fails, and the system stability is improved.

Description

technical field [0001] The present invention relates to communication technology, in particular to a data buffering method and device. Background technique [0002] At present, the network occupies an increasingly important position in people's daily life, and the performance of the network directly affects people's application experience. Among them, network speed is an important indicator that affects people's application experience. However, limited by the limited network bandwidth, people have begun to devote themselves to developing various technologies that can increase the speed of data transmission within the limited bandwidth. For example, P2P (peer-to-peer, peer-to-peer) technology is a popular network data transmission technology at present, and its transmission speed is improved mainly through distributed exchange of data. BT (BitTorrent, bit stream) technology is a typical application of P2P technology. The working principle of BT technology can be understood ...
