!!! Overview [{$pagename}]s are [Network devices] which transverses the entire [OSI-Model] Stack from the Top on one [host] to the top on the other [host]. An [example] would be a [{$pagename}] that could translate from [Ethernet] to [Token-Ring] so that the [payload] was intact and not altered. A [routing] on the other hand can only transfer [payloads] between similar [networks] and [Bridging] only if the same [Network Address] method is used. [{$pagename}] generally implies the [Payload] is not altered or even [Observed|Observer]. If the [Payload] is [Observed|Observer] then the [Network device] is considered a [Proxy]. [{$pagename}] [SHOULD NOT] need to determine the [URI Scheme], for example, of the [payload] !! [{$pagename}] [Classification] There are many specific [{$pagename}] [Classifications] * [Firewall] * [Application Load Balancing] * Payment Gateway * Residential Gateway - Often these are [{$pagename}]s which may have a [Firewall] * TV Gateway !!
