Abstract: Disclosed herein are techniques for tracking file system (FS) utilization by a plurality of applications. According to some embodiments, a technique can be implemented by a computing device on which the FS is implemented, and includes the steps of (1) receiving, from an application among the plurality of applications, a request to perform an input/output (I/O) operation pertaining to a first FS object, where the request includes a unique identifier (ID) associated with the application, (2) creating or locating, within the FS, the first FS object, (3) performing the I/O operation against the first FS object, (4) creating or locating, within the FS, a second FS object associated with the unique ID, and (5) updating the second FS object to reflect the I/O operation. Other techniques include observing, analyzing, etc., FS utilization by the plurality of applications.

Abstract: A method and apparatus for scheduling upstream data packets in a communication system is described. The present inventive method obtains a priority value (PV) for an upstream data packet and compares (using hardware registers) the PV of a queued upstream data packet to a current system timer. In accordance with one embodiment of the present invention, the current system timer comprises the current clock time of the communication system. When a PV equals the current system timer, the method transmits the upstream data packet associated with the PV to the CMTS via the upstream transmission path.
