Embodiment Construction

[0089] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following detailed description will be given in conjunction with the accompanying drawings and specific embodiments.

[0090] Existing methods for IPv6 asset management include probe collection method, DNS reverse query method, addressing rule method, and traffic analysis method. Each method can effectively discover IPv6 assets only under the premise of certain specific scenarios, but for general scenarios, most of the existing methods are difficult to efficiently discover and manage IPv6 assets.

[0091] Probe intensive collection method, by deploying intensive probe devices in each terminal subnet to monitor and detect IPv6 asset information in each subnet, the probe will report the collected information to the management center regularly, so as to achieve corrective actions. Collection of information about each IPv6 asset a...

Abstract

The invention provides an inter-network node information spreading method and device, and belongs to the technical field of network security. The inter-network node information spreading method is executed by a first router, the first router is adjacent to a second router on a network, and the method comprises the following steps: sending a link state update (LSU) message to the second router, a link state advertisement (LSA) in the LSU message comprising node information of the first router; and receiving a link state acknowledgement (LSACK) message replied by the second router, wherein the LSACK message comprises header header information of the LSA. According to the technical scheme of the invention, the data traffic generated in the node information spreading process can be reduced, and the method is suitable for a universal IPv6 scene.

Description

technical field [0001] The present invention relates to the technical field of network security, in particular to a method and device for disseminating node information between networks. Background technique [0002] With the promotion of IPv6 network deployment and application at the national level, more and more Internet asset devices have or are using IPv6 networks. Due to the large-scale deployment and application of various intelligent terminal equipment, Internet of Things facilities, and various application service platforms, as well as the accelerated commercialization of 5G networks, new scenarios such as autonomous driving and the Internet of Everything continue to emerge, and IPv6 networks will be used in the future. Assets and equipment may grow exponentially more than before. How to manage the assets in the IPv6 network space will face many new challenges in the above-mentioned situations. [0003] Challenge 1. The available address space for IPv6 is larger. ...
