The invention discloses a resource transmission method and a resource transmission device for a caching platform. The resource transmission method comprises the steps of acquiring resource information of networking devices, wherein the resource information is used for indicating resources corresponding to the networking devices; generating the resources to be issued of a multicast group based on the resource information, wherein the multicast group comprises the plurality of networking devices; and issuing the resources to be issued to each networking device in the multicast group by the issuing mode of the multicast group. According to the resource transmission method, the technical problem that the resource transmission efficiency is low during the resource transmission process of the caching platform is solved.
