Locust single-machine multi-core stress test, and data communication processing of master-slave nodes

Let me briefly explain the background first. Before the APP is launched, the login interface needs to be performance tested. After evaluation, I gave priority to locust for script development. This time I used locust’s single-machine multi-core running capability, but it also involves data communication between master and slave nodes. There are very few effective […]

Specific application of ROS Service Service communication mechanism in unmanned vehicles

1. Introduction In the communication mechanism, we have introduced this Service service before: Application of ROS Communication Mechanism Service (Service) It is generally suitable for scenarios where communication processing is relatively simple. Here we will actually operate some very common services on the unmanned vehicle: publishing voltage data, turning on and off LED lights, turning […]

Algorithm Issues in Communication Networks Experiment 4-Depth-First Algorithm and Breadth-First Algorithm (Node Traversal)

Experiment 4 Algorithm issues in communication networks-depth-first algorithm and breadth-first algorithm (node traversal) 1. Introduction In communication networks, node traversal is an important task that helps understand the topology of the network, identify potential problems, and perform various analyses. Depth-first search algorithm and breadth-first search algorithm are two commonly used graph traversal methods, which can […]
