Inbound/Incoming
Inbound traffic refers to data traffic that flows from external sources into a specific network. This can include, for example, user requests sent from external websites, servers, or other networks to a website or server.
Outbound/Outgoing
Outbound traffic refers to data traffic that is sent from a specific network to external destinations outside of that network. Typical examples include responses to user requests: a web server sends these back to the user’s browser. Data uploads from a local computer to a cloud service or another server are also considered outbound traffic.
This distinction between inbound and outbound data traffic is crucial for network administrators. It helps them monitor bandwidth usage, identify bottlenecks, and optimize network performance.
