Problems solved by technology

[0007] Although K-bucket shows excellent efficiency in each independent operation, in the field of network information monitoring, it is necessary to perform repeated operations on key information to achieve the purpose of long-term monitoring. In this case, use K-bucket routing Mode, the process of finding nodes is unavoidably repetitive and leads to inefficiency

Embodiment Construction

[0032] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] like figure 2 As shown, the present invention is aimed at the node maintenance method based on one-dimensional linked list of P2P network monitoring, comprises the following steps:

[0034] (1) Storage of node information; each node stores priority (priority), resNum (response times), resOutTime (non-response times) and node-related information. The relevant information here includes the ID of the node, the IP of the node, the TCP communication port of the node, the UDP communication port of the node, and the version information of the node.

[0035] priority indicates the priority of the node in this linked list, resNum indicates the number of responses received during the query process, and the ID of the node is a data randomly generated by the...

Abstract

The invention discloses a node maintenance method for P2P network monitoring based on one-dimensional chain tables. The method comprises the steps that according to the special needs of network monitoring application, monitored resources are repeatedly inquired to achieve the aim of monitoring the network, a traditional bucket K is abandoned, the one-dimensional chain tables are used for storing node information, the network is monitored through the inquiring function of the P2P network, the priority of nodes is set according to inquired feedback information, the one-dimensional chain tables are dynamically adjusted according to the priority of the nodes, therefore, the one-dimensional chain tables are arranged according to the priority to achieve the aim that the nodes with response information can be preferentially inquired in the next inquiring process, and therefore the inquiry of each time is prevented from being started from zero repeatedly, the number of iterations of the inquiry is reduced, inquiry time is greatly reduced, and the efficiency of monitoring the network is improved.

Description

technical field [0001] The invention belongs to the technical field of P2P networks, and in particular relates to a one-dimensional link list-based node maintenance method for P2P network monitoring. Background technique [0002] With the popularization of the Internet and the rapid development of digital technology, more and more digital content such as e-books, music, and movies are traded and disseminated online. The digitalization of online publishing and traditional paper works has become a development trend. However, because digital information is easy to be copied, modified and illegally disseminated, there are a lot of piracy and infringement problems in the digital content disseminated on the Internet. End users intentionally or unintentionally copy and paste digital content arbitrarily, especially for popular resources The secondary transmission (such as disk copy, network sharing, etc.) that is scrupled consumes potential users at an alarming rate, causing huge e...
