Network node and method of operating the network node

摘要

A method of operating a network node includes receiving a response packet including an encoded content name, decoding the encoded content name, and transmitting the response packet based on the decoded content name. The encoded content name is encoded based on a predetermined condition, or on an attribute rule comprising at least one attribute, wherein the network node satisfies the predetermined condition; and the decoding comprises decoding the encoded content name based on the predetermined condition, said predetermined condition being set by a network node configured to generate the response packet to limit a network range in which transmission of the response packet is allowed, said at least one attribute comprising either one or both of domain information; and interface information, wherein the attribute rule is associated with an access authority with respect to content included in the response packet.
