... A router is at layer 3. So, it connects LANs. LANs can have different layer 2s. How could we communicate between machines on different layer 2s? Answer: a router that speaks both layer 2s, and somehow translates. But, the machines have to be able to identify each other and have a common “language”. ...

Basically, there are centralized and distributed models, where the routing computation is done in a centralized server or in multiple PCEs in the network. Moreover, there are single layer cooperating PCEs, where each PC ...

Distributed firewall

A firewall is a system or group of systems (router, proxy, or gateway) that implements a set of security rules to enforce access control between two networks to protect ""inside"" network from ""outside"" network. It may be a hardware device or a software program running on a secure host computer. In either case, it must have at least two network interfaces, one for the network it is intended to protect, and one for the network it is exposed to. A firewall sits at the junction point or gateway between the two networks, usually a private network and a public network such as the Internet.
