Flannel Network K8s itself does not handle network communication; it provides a Container Network Interface (CNI) for this purpose. The communication is managed by CNI plugins, of which there are many open-source options, such as Flannel and Calico. Although K8s does not manage the network, it requires that Pods within the cluster can communicate with … Read more
The OpenWRT system achieves data transmission between Ethernet (wired) and WiFi (wireless) through a multi-layer network architecture design and inter-process communication (IPC) mechanisms. Its core design includes network interface bridging, inter-process communication framework (ubus), firewall and routing rules, and unified configuration management system. The following are the specific implementation principles and key components: 1. Network … Read more
To configure a device in OpenWrt to function simultaneously as an AP (Access Point) and STA (Client) for network bridging, the following steps must be completed. This configuration allows the device to connect to an upstream WiFi (STA mode) while providing wireless access to downstream devices (AP mode), enabling network extension or use when a … Read more
