Apparatuses and methods for distributing and/or receiving buffer content advertisements continuously to and/or from a plurality of neighboring peer apparatuses joined in a network are described. The buffer content advertisements identify the stored packets of data in a packet buffer. The continuously distributed and/or received buffer content advertisements may include incremental updates of content of the packet buffer piggybacked to every outgoing and/or incoming packet of data. The apparatus may determine packets of data advertised by a plurality of neighboring peers that the apparatus does not have in its packet buffer, and may request packets of data, of the advertised packets, from at least one of the plurality of neighboring peers. The apparatus may include a communication module to communicate buffer content advertisements continuously to the plurality of neighboring peers.
