Setting Up an MQTT Testing Environment (Part 1)

Setting Up an MQTT Testing Environment (Part 1)

Recently, I have been testing the integration of Mobotix cameras with HomeAssistant. Through testing, I found that the images from Mobotix cameras can be successfully integrated into HomeAssistant via the Onvif protocol or RTSP. So how can the alarm signals from the Mobotix cameras be integrated into HA? Since Mobotix cameras support the MQTT protocol, … Read more

How the Minimum Frame Length of 64 Bytes in Ethernet for TCP/IP Protocol is Determined

How the Minimum Frame Length of 64 Bytes in Ethernet for TCP/IP Protocol is Determined

The TCP/IP protocol specifies that the minimum frame length for transmission is 64 bytes; any frame shorter than 64 bytes is considered invalid. So, how was this 64 bytes determined? This can be traced back to the CSMA/CD protocol. As is well known, early Ethernet operated on a shared bus, where multiple computers were connected … Read more
