    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium for Content Delivery Networks Interconnection (CDNI) request routing using the PCP FLOWDATA option. In one aspect, a method includes receiving a request for content, and receiving, from a PCP server, flow characteristics for providing the content, where the PCP server receives the flow characteristics for providing the content from a PCP proxy that receives the flow characteristics from the client device. The method includes transmitting first data for querying the downstream content delivery network (CDN) to determine whether the downstream CDN can provide the content and satisfy the flow characteristics. The method includes receiving a response indicating the ability of the downstream CDN to provide the content and satisfy the flow characteristics, and transmitting second data based on the response, where the client device transmits flow metadata based on the second data to the PCP proxy.

    Abstract: In one embodiment, a client device includes a processor to send a first GET request to a server for a first data chunk of a data item, a communication interface to receive packets of the first data chunk, a buffer to buffer the packets, wherein the processor is operative to obtain a first measure of round trip time (RTT), the processor is operative to estimate a time t1 when receipt of the last packet of the packets of the first data chunk in the buffer will be completed, the processor is operative to determine a next fetch time, t2, to send a second GET request to the server for a second data chunk of the data item, based on the time t1 adjusted by a portion of the first measure of RTT, the processor is operative to send the second GET request to the server at about time t2.
