SAABCOT: Secure application-agnostic bandwidth conservation techniques

High speed modern networks are tasked with moving large amounts of data to diverse groups of interested parties. Often under heavy loads, a significant portion of the data exhibits large amounts of redundancy on short and/or long-term time scales. As a result, a large body of work has emerged offering bandwidth conservation exemplified by the work in caching and multicast. The majority of the techniques that have experienced widespread adoption rely on parsing / reacting to application-specific data. With the advent of simplified end-to-end security, as introduced by IPv6, these techniques will no longer have access to the plaintext data. We present a novel technique for preserving security while allowing in-network devices to identify redundant data flows in order to apply bandwidth conservation techniques. Our communication protocol does not require modifications to existing applications nor does it inflict a significant amount of overhead to the existing network infrastructure.
