15Ethernet link aggregation and switch stacking and clustering

1. Network reliability requirements 1. Network reliability Network reliability refers to the ability to ensure uninterrupted network services when single or multiple points of equipment or links fail. Network reliability can be achieved at multiple levels, including boards, devices, and links. 2. Single board reliability 2.1.Single board reliability-1 A modular switch consists of a chassis, […]

python and PLC communication (Ethernet modbustcp)

To establish communication with a PLC in Python, you usually need to perform the following steps: 1. Determine the communication protocol of the PLC: Different PLC manufacturers and models may use different communication protocols, such as Modbus, OPC UA, Profinet, etc. Please first determine which communication protocol your PLC uses (this article is modbustcp). 2. […]

Android13 Ethernet and WIFI coexist

1. Introduction In actual project development, especially when Ethernet-related functions are used, it often involves the situation where WiFi and Ethernet are turned on at the same time. Android has very little native compatibility for this. Only one will take effect, and Ethernet will be used first. Therefore, the system mechanism needs to be changed […]

Plug and play: How Ethernet switch combo ports change the game for network connectivity?

Hello, this is the Network Technology Alliance site. In modern networks, Ethernet switches are key devices widely used to connect various network devices. These switches typically have multiple ports for connecting computers, servers, routers, and other network devices. Combo port is a special type of port that changes the functionality and flexibility of the switch […]
