Internet Protocol switching definition

Internet Protocol switching

(also IP switching, multi-layer switching)

Internet Protocol switching is a network technology that combines routing and switching to forward data packets in a network (i.e., to send information). In traditional methods, each data packet is looked at individually to decide where it should go next. In IP switching, when the best route for a data packet is found, it is remembered without re-evaluating it each time. IP switching is typically quicker than traditional routing and can be great for busy networks.

How Internet Protocol switching works

When a data packet arrives at an IP switch, the switch looks at its destination IP address (i.e., where the packet needs to go).
The IP switch uses special hardware to look up the destination IP address.
Based on the lookup, the IP switch determines the best port for the packet.
The packet is immediately forwarded through the selected port, allowing the data to travel quickly and efficiently within the network.

Benefits of IP switching

IP switching is fast and can forward data much quicker than traditional routing.
It optimizes network traffic flow, reducing congestion and latency for smoother data transmission.
IP switching simplifies the network by combining routing and switching into one device, making it less complicated.
It can easily accommodate growing networks, making it suitable for both small and large organizations.

IP switching limitations

Configuring IP switching can be complex.
IP switches may not provide the same advanced routing features as dedicated routers.
High-speed IP switching needs specialized hardware, which can be resource-intensive.
