→ A network protocol developed by Cisco for the collection and monitoring of network
traffic flow data generated by NetFlow-enabled routers and switches (Rouse, 2014)
Original networking protocol for DOS and Windows PCs:
→ NetBIOS

→ The original networking protocol for DOS and Windows PCs. These packets did not
contain a network address and were not easily routable between networks. As a
result, the interface to NetBIOS and the transport part of NetBIOS were later
separated so that NetBIOS applications could use routable protocols such as TCP/IP
and SPX/IPX (PC Magazine, 2018).
Most common way network address translation is implemented. Also called "NAT overloading,"
or "network address port translation" (NAPT):
- Port Address Translation (PAT)
- NetFlow
- NetBIOS
- Switching
- Hosts

overloading," "network address port translation" (NAPT) and "NAT/PAT."
→ It assigns a different TCP port number to each client session with a server on the
internet. When responses come back from that server, the source port number becomes
the destination port number and determines which user to route the packets to. It also
validates that the incoming packets were indeed requested (PC Magazine, 2018).
Serves as a standard template for describing a network protocol stack:
- Border Gateway Protocol (BGP)
- Open Systems Interconnection Model (OSI Model)
