As a result, Internet devices usually use a single path and let the routers handle the path selection. Enter Multi-Path TCP (MPTCP), which exploits the presence of multiple interfaces on a device, such as a mobile phone that has both Wi-Fi and cellular antennas, to achieve multi-path connectivity. Only for low-bandwidth flows.

Flow-based network monitoring relies on collecting information about packet flows (i.e. a sequence of related packets) as they traverse routers, switches, load balancers, ADCs, network visibility switches, and other devices. Flow-based monitoring provides significant advantages over other network monitoring methods.

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. Sometimes, your connections don’t have enough bandwidth.

Some of these devices an enterprise network engineer owns and manages, and a lot of it they don’t. Rather than collecting only flow data from routers, or only eBPF information from containers, the fact that application traffic traverses so many devices means we need much more data to get an accurate view of what’s happening.

The quality of the network router switches and network interfaces. The software/driver/firmware stack that needs to be executed to send or receive a network packet (referred to as the open systems interconnection, or OSI).
