How does Gateway Work?
Gateway has a simple working methodology of five steps:
- Step 1: It gets data from the network
- Step 2: It intercepts and analyzes the received data.
- Step 3: It routes the data to the destination address.
- Step 4: It converts the received data to make that compatible with the receiver network.
- Step 5: It sends the final data inside the network.
Actually what happens on the gateway after receiving a data packet is that they check header information that is present in the data packet. After that, it validates the destination IP address and searches for any error. If it gets no error then it makes that data packet compatible for the new network by converting protocols or other stuff.
What are Gateways in Computer Network?
A gateway is a network node or device that connects two networks that use different transmission protocols. Gateways play an important role in connecting two networks. It works as the entry-exit point for a network because all traffic that passes across the networks must pass through the gateway.
