Claim Text:
1. A computer-implemented method comprising: receiving, by an upstream content delivery network and from a client device, a request for content; receiving, from a PCP server, flow characteristics for providing the content, wherein the PCP server receives the flow characteristics for providing the content from a PCP proxy that receives the flow characteristics from the client device; transmitting, to a downstream content delivery network, first data for querying the downstream content delivery network to determine whether the downstream content delivery network can provide the content and satisfy the flow characteristics; receiving, from the downstream content delivery network, a response indicating the ability of the downstream content delivery network to provide the content and satisfy the flow characteristics; and transmitting, to the client device, second data based on the response indicating the ability of the downstream content delivery network to provide the content and satisfy the flow characteristics, wherein the client device transmits flow metadata based on the second data to the PCP proxy, and wherein the PCP proxy transmits the flow metadata to the PCP server to indicate a priority level to give to the content received from the downstream content delivery network.
