Deep Packet Inspection is a way of checking and filtering data in a packet when it is being passed, for things such as viruses and spams. DPI decides if the packets can be passed. It also decides the time and if it is important for it to be sent right away or if there is too much traffic on the network, the packets will be held. There are a lot of controversies about DPI as many people think it is a breach of privacy.
