Multi-interface fusion method of communication node

The invention discloses a multi-interface fusion method of a communication node, which comprises the following steps: establishing an address table and an interface table; regularly testing the state and the parameter information of each network interface by a state/parameter maintenance module; wiring the state and parameter information of each network interface into the interface table and updating the interface table; automatically distributing business data to be sent out by the communication node by a business leading module according to the interface state information of the interface table; and sending out the business data through the set network interface so that the defects of inconvenient interface management and maintenance of the manual closing of a network interface by users or manual route table configuration in the prior art. At the same time, when a plurality of network interfaces capable of visiting the outer network or the inner network exist, the optimal network interface is further selected for outwards sending according to the performance parameter of the outer network connection of the interface table, or the business data carry out load balance on the network interfaces, so the business data can be distributed to the optimal network interface, or the business data can be transmitted and distributed to a plurality of network interfaces, and the integral transmission bandwidth of the outer network or the inner network of the system is indirectly improved.
