US 2017/0374085 A1 · METHOD FOR DEEP DATA INSPECTION OVER AN INDUSTRIAL INTERNET FIELD BROADBAND BUS

Abstract

The invention discloses a method for deep data inspection over an industrial internet field broadband bus, the method including: obtaining, by a first node, a message to be transmitted; judging, by the first node, whether a bus device address in the message to be transmitted lies in a preset range of bus device addresses; and if the bus device address lies in the preset range of bus device addresses, then transmitting, by the first node, the message to be transmitted to a processor of the first node. The first node only forwards the message to be transmitted, lying in the preset range of bus device addresses to thereby improve the security of transmitting the message.

Dependent claims

A method for deep data inspection over an industrial internet field broadband bus, the method being applicable to a two-wire data transfer network in which respective nodes are connected over the network according to their IP address, and the respective nodes are synchronized in clock, wherein the method comprises:

obtaining, by a first node, a message to be transmitted;
judging, by the first node, whether a bus device address in the message to be transmitted lies in a preset range of bus device addresses;
and
if the bus device address lies in the preset range of bus device addresses, then transmitting, by the first node, the message to be transmitted to a processor of the first node.
