I embarked on an embedded project to learn more about networking. Let's say I'm looking to have a PLC as a Modbus TCP server with dual Ethernet ports. On one port I would like to connect the PLC to a LAN either in star or ring topology. The second port should be used to connect other ethernet devices/PLCs in daisy chain.

This method, called passive OS fingerprinting, involves matching uniquely identifying patterns in the network traffic a host produces, and classifying it accordingly. In most cases, these patterns are evaluated on a single network packet, rather than a sequence of flows between a client host and a server.

For one, cloud refers to the move to distributed application architectures, where components are no longer all resident on the same server or data center, but instead are spread across networks, commonly including the Internet, and are accessed via API calls. It’s high time for network performance monitoring to come into the cloud era.

On a network, configurations are constantly changing. Unfortunately, configuration change accidents can happen that bring down parts of the network. Interface dropping packets. Interface issues caused by misconfigurations, errors, or queue limits lead to network traffic failing to reach its destination.
