Ingress and Egress Traffic

The terms “ingress” and “egress” refer to how data flows into and out of a network.

Ingress refers to the process of data entering a network. Egress, on the other hand, refers to the process of data leaving a network.

Ingress points in a network can include routers, switches, firewalls, and other network devices that receive data packets from external sources. Egress points in a network can include routers, switches, gateways, and other devices that transmit data packets to external networks or destinations.

When data enters a network, it passes through ingress points where it may undergo various processes such as filtering, inspection, and routing. Just like ingress, before data packets are transmitted out of the network, they may undergo various processes such as routing, filtering, and shaping to optimize the flow of data and ensure it reaches its intended destination efficiently.

The efficient management of ingress and egress points is critical for network performance optimization. Ingress points help protect the network from potential threats and unauthorized access, while egress points ensure efficient data transmission to external networks or destinations.
