Packet injection (also known as forging packets or spoofing packets) in computer networking, is the process of interfering with an established network connection by means of constructing packets to appear as if they are part of the normal communication stream. The packet injection process allows an unknown third party to disrupt or intercept packets from the consenting parties that are communicating, which can lead to degradation or blockage of users' ability to utilize certain network services or protocols. Packet injection is commonly used in man-in-the-middle attacks and denial-of-service attacks.
High energy efficiency task scheduling system for heterogeneous many-core network-on-chip based on multi-armed bandit
This invention discloses a high-efficiency task scheduling system for heterogeneous multi-core on-chip networks based on a multi-armed slot machine, relating to the field of task scheduling in heterogeneous multi-core systems. It addresses the problem of high power consumption in existing scheduling technologies by proposing this solution. During runtime, the following scheduling steps are periodically executed using time slices as the cycle: S1. Status acquisition of the underlying hardware platform and upper-layer application load; S2. Time and power consumption estimation based on on-chip network prediction; S3. Calculation of priority index and net gain; S4. Allocation of heterogeneous cores based on integer linear programming; S5. Runtime closed-loop feedback and control parameter updates. The advantage is that when the scheduler calculates the net gain, it imposes a strong mathematical penalty on applications with high packet injection rates that excessively distribute core allocation. This forces the system to perceive NoC traffic hotspots during runtime and intelligently converge applications with high communication demands to core configurations that are physically closer. This avoids problems such as virtual channel deadlock and bus congestion in NoC routers.
