BGP

Term from Network Services industry explained for recruiters

BGP (Border Gateway Protocol) is like a postal system for the internet - it's how different networks share information about the best paths to send data between them. When companies mention BGP in job descriptions, they're looking for people who can help manage how their network connects to other networks, including internet service providers. This is especially important for large organizations that need reliable internet connections. Think of it as being the traffic controller for internet data, making sure information takes the best possible route. Similar terms you might see include "routing protocols" or "internet routing."
