Example Embodiment

[0029] Specific implementation method

[0030] The present invention will be described in detail below with reference to the drawings and embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and specific operation process are given, but the applicable platform is not limited to the following embodiments.

[0031] Such as figure 1 As shown, the present invention divides any three consecutive two-hop nodes in the Internet into a collection node C (Collector), a suspect node S (Suspect), and a monitoring node R (Spotter). The data flow is initiated by the collecting node, after asymmetric encryption, the data is transmitted to the monitoring node through the transmission of the suspect node. After the monitoring node receives the data, it passes the verification and aggregates the information back to the collecting node. The collecting node judges whether the suspect node has an error or w...

Abstract

The invention discloses an error positioning method for a distributed dynamic routing network. Three nodes of any two continuous hops in the internet are divided into a collecting node, a suspicion node and a monitoring node. Data traffic is initiated by the collecting node, and after asymmetric encryption is carried out, data are transmitted to the monitoring node through the suspicion node. After the monitoring node receives the data and verification is passed, information is gathered and fed back to the collecting node. The collecting node judges whether the suspicion node has errors or not or whether the suspicion node is a malicious node or not according to the data transmitted to the suspicion node and feedbacks of the monitoring node. By means of the error positioning method, positioning of three errors including data package content damage, node error packet losing and retransmission and node spite delaying and data package out-of-order transmission is achieved.

Description

technical field [0001] The invention relates to the field of wrong location of computer network direction. Specifically, it is mainly an algorithm for error location through random hop verification in a distributed dynamic routing network environment. Background technique [0002] With the continuous expansion of the scale of the Internet, the selection of routes by routers and the forwarding of data packets have a greater and greater impact on the speed and quality of data transmission. [0003] However, due to the vulnerability of the router itself due to bugs and configuration errors considered by the administrator, problems such as packet loss, retransmission, and out-of-sequence occur frequently. As a result, the quality of service (Quality of Service, QoS) of the network will decline, and it may also be exploited by hackers, resulting in a series of security threats such as Denial-of-Service and Man-in-Middle attacks. question. Therefore, quickly locating the wrong ...
