Problems solved by technology

However, due to the individual differences between each service node, the service performance of each service node may be different. If the data request cannot be sent in a targeted manner according to the service performance difference of each service node, it is not conducive to the improvement of download performance.

specific Embodiment approach

[0025] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] First of all, since different service nodes belong to different network topologies, the network links between each service node and local nodes are also different, and will reflect different service performances. Therefore, an efficient data download scheduling technology should be able to adapt to the service status of the current service node, send data requests in a targeted manner according to the performance of each service node, download more data from service nodes with good performance, and reduce the impact on low-performance nodes. The data request of the service node to ultimately improve the overall download capacity.

[0027] Network traffic changes in real time, and the service performance of each service node als...

example

[0044] In this example, when the local node sends an initial data request to the service node, it first records the time when the initial data request is sent, the requested data volume of the initial data request, and when receiving data, records the time when the first data packet arrives at the local node and the last The time a packet arrives at the local node.

[0045] Then, take the time when the first data packet arrives at the local node minus the time when the initial data request is sent as parameter one; The time difference is used as parameter 2; finally, parameter 1 and parameter 2 are integrated through a certain weight distribution as the current service performance parameter of the service node. In this way, after one request cycle, each service node will obtain real-time service performance parameters. Local nodes can schedule data downloads according to the real-time performance parameters of each service node.

[0046] This embodiment specifically includes...

Abstract

The embodiment of the invention provides a data scheduling method of P2P networks and a system thereof. The method comprises the steps that: local nodes send an initial data request to all service nodes and all the service nodes send back the initial data to the local nodes; the local nodes calculate the performance parameters of all the service nodes respectively according to the performance indexes of all the service nodes transmitting the initial data; all the service nodes are sorted according to the performance parameters calculated and a data request is carried out again to service nodes according to the sorting result. The method and the system can improve downloading performance, realize real-time monitoring towards the performance of all the service nodes, control the current downloading scheduling by utilizing the monitoring situation, thereby guaranteeing full and effective utilization of the current service nodes and being able to self adapt to the change of network situations.

Description

technical field [0001] The present invention relates to the technical field of peer-to-peer connection (peer to peer, P2P), and more particularly, to a data scheduling method and system for a peer-to-peer connection network. Background technique [0002] The development and evolution process of computer network is swinging between centralization and distribution. In the early computer usage mode, many users shared large computers, and later developed personal computers, moving from centralized to distributed. A similar situation exists on the Internet, where a client (browser)-server approach has begun, using a centralized server on a website. Further development will move toward distributed, centralized servers will become distributed, and each user terminal is both a client and a server, which is the peer-to-peer (P2P) mode. [0003] P2P is a peer-to-peer Internet technology. Simply put, P2P directly connects people and allows people to interact directly through the Int...
