Multi-homed network routing and forwarding method based on programmable network technology

摘要

When the routing and forwarding of data packets are performed, the present invention performs address-to-port matching according to the forwarding flow table address matching method, and each port is matched according to the matched port to correspond to one destination address group. Classifying the address; Selecting an appropriate port and a corresponding destination address group based on the information and port selection function from the link information table, and tailoring the destination address group of the remaining ports; Further tailoring the remaining destination address groups using the address filter function and previous hop information provided in the data; If it is possible to determine a single destination address by selecting a single address for the remaining addresses in the destination address group, use it as the destination address, and forward the message to the destination address using normal routing and forwarding methods, otherwise, the destination address group Disclosed is a method of routing and forwarding a multi-homed network based on programmable network technology, comprising packaging and determining a single destination address per hop using a single address selection method until a destination address is reached.
