220.127.116.11 Chunk Generation
RDC chunk generation takes as input a file and two parameters, the hash window and the horizon, and produces a set of offsets into the file that indicates the start of the chunks of the file. Prior to their use, the hash window and the horizon MUST be negotiated between the source location and target location of the file to ensure that chunks are generated consistently on both ends. Negotiation of hash window and horizon is application-specific and is not addressed in this document.<1>
The following diagram illustrates chunk generation.

With each chunk, RDC computes a signature. See section 18.104.22.168.
