摘要

According to one aspect, a method includes obtaining a request for content through a physical network layer at a first node, the first node being one of a plurality of nodes in a content network layer, each node of the plurality of nodes including the content, wherein the request includes a first packet. The method also includes identifying a second node of the plurality of nodes from which to obtain the content, and inserting a segment routing (SR) list into the first packet, the SR list specifying an address of the second node as a next destination of the first packet. Finally, the method includes providing the packet including the SR list from the first node to the second node, wherein the second node is arranged to change the next destination of the packet to an address of the content included on the second node.
