COMMUNICATION DEVICE CAPABLE OF MULTI-PATH DATA TRANSMISSION, DATA COMMUNICATION NETWORK SYSTEM AND DATA COMMUNICATION METHOD

摘要

Disclosed is a communication device capable of multi-path data transmission, comprising: two or more network link ports, and a path decision component comprising a data modification unit, a learning unit and a path decision unit. The data modification unit modifies path information. The learning unit is used for learning a port number, the path information and a source user switch ID, and forming a user switch ID table. The path decision unit queries the user switch ID table, and sends, based on a destination user switch ID, a data frame to the one or more network link ports. Also disclosed are a communication network and communication method using the communication device.
