AI Technical Summary

Problems solved by technology

Due to the lack of security protection when verifying adjacent nodes, anyone can interfere with the receiving end by sending the same packet content and format to deceive the receiving end node, so that the developed application cannot operate normally
This may include examples such as when a customer's operating system is compromised by a hacker, or when a malicious user wants to intentionally trick the network

Abstract

A network system is provided to coordinate nodes in a network topology to exchange neighbor information. The network system includes a plurality of processing nodes, where each processing node includes a processing node manager configured to receive a key via a secured connection, wherein the key comprises an instruction to forward advertised discovery packets to each of the plurality of processing nodes; send advertised discovery packets advertising network port information to each of the other plurality of processing nodes; and receive and examine advertised discovery packets from each of the other plurality of processing nodes, the advertised discovery packets comprising an authentication code, wherein examining the advertised discovery packets comprises verifying the authentication code is compliant with the received key.

Description

technical field [0001] The present invention relates to the field of data security, in particular to providing data security protection to network units, especially providing coordinated nodes into network topology to exchange information of adjacent nodes and avoid deceiving packets to interfere with network topology generation. Background technique [0002] In an established network topology, such as in a data center, each node may want to discover information about each other's neighbors. In general, the more information is exchanged, the more applications can be developed based on the information exchanged. Protocols designed for this purpose are well known, including Link Layer Discovery Protocol (LLDP) and Cisco Discovery Protocol (CDP), for example. LLDP is a well-known neighbor discovery protocol that allows Ethernet network devices to publish topology information such as device configuration and detailed identification information to nearby devices. For example, a...
