Abstract: The present invention relates to a method for accessing a switch external memory from a control plane and a data plane. A control module issues information about an authorized entity and an authorized operation to a switch, and the switch receives and stores the authorized information; the switch receives a file I/O operation instruction and determines whether an operation entity has the authority of the file I/O operation instruction according to the instruction and the authorized information; and for the operation entity having the authority of the file I/O operation instruction, the switch extracts an instruction index and parameter from the file I/O operation instruction and executes a file I/O operation.

Abstract: The present invention relates to a content-centric network on-demand distance vector route method, comprising: a request source node of a required request route broadcasts a route request packet CCN_RREQ to other nodes in a network, and starts a route discovery process; after a target node receives the route request packet CCN_RREQ, replying with a route reply packet CCN_RREP; after the request source node receives the route reply packet CCN_RREP returned by the target node, establishing a path between the request source node and the target node according to the content of the route reply packet CCN_RREP.
