Abstract
A programmable network technology-based multi-homed network routing and forwarding method includes a data packet performing address-to-port matching a forwarding flow table address matching method; classifying addresses to matched ports corresponding to a destination address group; selecting a link information table and a port selection function, an appropriate port and a corresponding destination address group; cropping destination address groups of the remaining ports using an address filtering function and previous hop information carried in data to further crop the remaining destination address groups and addresses in the destination address group, a single destination address can be determined using a single address selection method, taking the single destination address using a universal routing and forwarding method to forward a packet to the destination address; otherwise, packaging the destination address group, and using a single address selection method to determine the single destination address hop by hop until the destination address is reached.
