Data transmission method and system

Abstract

The invention relates to a data transmission method, which comprises the following steps that: duplicate resource data information of a resource file which is downloaded and distributed from the whole network is collected from the client, a push resource list and an abandonable push resource list are generated according to the downloaded and distributed duplicate resource data information of the resource file and are transmitted; basic information of the client when in running is acquired, whether the basic information conforms to a set push initial condition is judged, if the basic information conforms to the set push initial condition, a push request is transmitted, and if the basic information cannot conform to the set push initial condition, the push request is not transmitted; and a push task is returned according to the push request, and corresponding push resource is downloaded from a network according to the returned push task. In addition, the invention also provides a data transmission system. Due to the adoption of the data transmission method and the system, the download task is reasonably and initiatively pushed according to the basic information of the client, so the client stores and uploads the resource, the distribution of the resource on the network can be balanced, the utilization rate of the client network bandwidth can be improved, the peer-to-peer (P2P) download performance can be improved, and the server bandwidth can be saved.

Description

【Technical field】 [0001] The invention relates to the field of Internet data transmission, in particular to a data transmission method and system. 【Background technique】 [0002] A peer-to-peer network (such as a Peer-to-Peer network, referred to as a P2P network) is a network topology that can be dynamically configured in any environment without requiring other infrastructure. Compared with the traditional network, it has the characteristics of self-organization, multi-hop routing and dynamic topology. The peer-to-peer network is easy to realize full utilization of resources and maximum sharing. [0003] In the traditional client / server (Client / Server) mode, data distribution uses a dedicated server, and multiple clients obtain data from this server. This mode can achieve data consistency and is easy to control and manage, but Due to the limited number of servers, the system is likely to have a single failure point, and a single server faces many clients. Due to the limit...

[0004] However, in the current P2P network, due to the uneven distribution of user interests, the distribution of resources in the network is also extremely uneven, and the diffusion speed of resources in the network is relatively lagging behind the transfer speed of user interests. The law causes the distribution of resources in the network to be extremely unbalanced with user needs, and the download speed of different resources varies greatly

For example, in the initial stage of the release of some new popular resources, the user demand is large and the copies of P2P network resources are insufficient, resulting in a sharp increase in server pressure and slow user download speed.

[0005] In addition, a small number of active client users have a large number of resources and undertake the main upload task, while another part of idle clients have no resources or have a small amount of unpopular resources, so that their upload bandwidth is wasted
