Overview#Gateways are Network devices which transverses the entire OSI-Model Stack from the Top on one host to the top on the other host.
Gateway generally implies the Payload is not altered or even Observed. If the Payload is Observed then the Network device is considered a Proxy. Gateway SHOULD NOT need to determine the URI Scheme, for example, of the payload
Gateway Classification#There are many specific Gateway Classifications
- Application Load Balancing
- Payment Gateway
- Residential Gateway - Often these are Gateways which may have a Firewall
