Abstract
The present invention discloses a satellite network code caching method based on Named Data Networking (NDN) and relates to the technical field of satellite network caching. Aiming at the transmission dependency generated by segmenting a content by conventional NDN caching, i.e., the problem that a user has to acquire a data block that requests a file block to be associated up and down to recover source data. The method removes the transmission dependency of data by adopting an encoding operation. To achieve efficient content distribution, the method places satellite node encoding packets by taking a minimized backhaul link load and a minimized content acquisition time delay as optimization objectives. An optimization problem is solved through a multi-population ant colony algorithm, and meanwhile, the content is retrieved rapidly.
