  • Patent number: 11502956
    Abstract: A method for content caching in information centric network virtualization includes receiving, by a first node, a first data packet; in response to a cache distance identifier hop of the first data packet being less than a preset maximum cache distance, setting hop=hop+1 and sending the first data packet to a next node by the first node; in response to the hop being not less than the preset maximum cache distance and there being available cache space in the first node, setting hop=0, storing the first data packet, and sending the first data packet to the next node by the first node. The node determines whether to cache a data packet based on the cache distance identifier of the data packet, which comprehensively considers the cache energy consumption caused by caching the data packet in the node and the transmission energy consumption caused by transmission of the data packet in the link, thereby effectively reducing the total energy consumption of the network.
