NETWORK SCHEDULING METHOD AND SYSTEM FOR REALTIME APPLICATIONS AND CORRESPONDING COMPUTER-READABLE STORAGE MEDIUM

摘要

A network scheduler for real time applications is described. The network scheduler supports scheduling of network packets in a multi-threaded operating system to insure correct scheduling order and to preclude kernel preemption of active threads. The network scheduler resides between a kernel (and device drivers) and multiple sessions at the user-level. The network scheduler uses input/output control primitives such as HOLD and RELEASE to control servicing of the queues of packets at the kernel or network device driver. The control primitives serve as a middleware interface to the underlying kernel or network device driver. The network scheduler functions as a proxy scheduler to manage the queues of packets at the kernel or network device driver.
