US 11,232,052 B2 · Timing control method and system applied on the network simulator platform

Abstract

A timing control method and system applied on the network simulator platform are disclosed. When at least one subprocess calls a system call to enter a blocking I/O, a marking operation is performed, the kernel issues a first notification event to a network simulator, to request the network simulator to pause until the subprocess leaves from the blocking I/O. when the kernel detects that the subprocess leaves from the blocking I/O already, the kernel issues a second notification event to the network simulator, so that the network simulator continues to simulate. The present invention can control the subprocess to not continuously occupy resource, and first and second notification events can prevent a simulator timer from continuously running during the subprocess execution period, to cause an abnormal timing of a simulation result.

Dependent claims

A timing control method, applied on a network simulator platform, wherein a network simulator is installed in a computer and configured to simulate at least one target software, and the timing control method comprises:

when at least one subprocess calls a first system call to enter a blocking I/O, performing a marking operation;
when a kernel detects that the at least one subprocess enters the blocking I/O, issuing a first notification event to inform the running network simulator that a status of the at least one subprocess is changed, and request the running network simulator to pause until the at least one subprocess leaves the blocking I/O;
and
when the kernel detects that all of the at least one subprocess leaves the blocking I/O already, issuing a second notification event to the network simulator, so that the network simulator continues to operate.

A timing control system applied on a network simulator platform, comprising:

a network simulator installed in a computer and configured to simulate at least one target software;
at least one subprocess, wherein when the network simulator and the at least one subprocess use the same resource and the subprocess calls a first system call to enter a blocking I/O, a marking operation is performed;
and
a kernel, wherein when detecting that the at least one subprocess enters the blocking I/O, the kernel issues a first notification event to inform the running network simulator that a status of the at least one subprocess is changed, and request the network simulator to pause, so that the at least one subprocess entering the blocking I/O uses the resource by turns, and when the kernel detects that all of the at least one subprocess leaves the blocking I/O already, the kernel issues a second notification event to the network simulator, so that the network simulator continues to operate.
