Methods, systems, and media are provided for the improved efficiency in bandwidth usage for transmitting repeated packets in a manner that is transparent to users. Fast, in-network per-packet caches (INPPC) at each node of a transmission retain packets for a configurable period of time or a number of packets. Rather than retransmit data from a first node to a second node within the time period for retention, an identifier is sent. The identifier allows the receiving node to access the first packet still in cache memory and reduces the size of the transmission, thereby optimizing bandwidth usage. Signatures that allow for efficient determination of packet redundancy, such as hashes, can be used. Accordingly, less bandwidth is utilized for repeated transmissions, such as transmission control protocol (TCP) retransmissions, or users accessing the same content within close proximity both physically and temporally.
