Abstract: A method and apparatus for a calibrated variable phase offset timing between synchronous clock subdomains is described. In one embodiment, the invention is an apparatus. The apparatus includes a first subsystem and a second subsystem coupled to the first subsystem. The apparatus also includes a clock signal generator coupled to the first subsystem and coupled to the second subsystem. The clock signal generator is to supply a first clock to the first subsystem and to supply a second clock to the first subsystem and to supply a third clock to the second subsystem. Each of the first clock, the second clock and the third clock are derived from a common clock, the first clock having a first predetermined phase offset relative to the third clock, and the second clock having a second predetermined phase offset relative to the third clock. The first predetermined phase offset and the second predetermined phase offset are adjustable based on performance characteristics of the first subsystem and performance characteristics of the second subsystem.

Abstract: One embodiment of the present invention provides a system for distributing files across a network. During operation, the system receives a request at a server to download a file to a client. If the server is not currently downloading the file, the system commences a download stream for the file on a multicast port. If the server is currently downloading the file, the system remembers a marked location on the file, wherein the marked location relates to a current packet number of the download stream on the multicast port. The system then continues downloading the file until the end of the file, thereby allowing the client to receive the remainder of the file. Next, the system downloads the file from the beginning of the file to the marked location, thereby allowing the client to receive previously transmitted portions of the file.
