A bridge router or brouter [1] is a network device that works as a bridge and as a router. The brouter routes packets for known protocols and simply forwards all other packets as a bridge would. [2] Brouters operate at both the network layer for routable protocols and at the data link layer for non-routable protocols. As networks continue to ...
The bridge has three ports. A is connected to bridge port 1, B is connected to bridge port 2, C is connected to bridge port 3. A sends a frame addressed to B to the bridge. The bridge examines the source address of the frame and creates an address and port number entry for host A in its forwarding table. The bridge examines the destination ...
A network switch (also called switching hub, bridging hub, Ethernet switch, and, by the IEEE, MAC bridge [1]) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.
Competing WAN technologies (T1, ISDN) required a router on the customer premises. PPPoE used a different Ethernet frame type, which allowed the DSL hardware to function as simply a bridge, passing some frames to the WAN and ignoring the others. Implementation of such a bridge is multiple orders of magnitude simpler than a router.
As traffic passes from the network to the Internet, NAT translates the source address in each packet from a private address to the router's public address. The router tracks basic data about each active connection (particularly the destination address and port). When the router receives inbound traffic from the Internet, it uses the connection ...
Wireless routers perform the same functions as a wired router and base station, but allow connectivity for wireless devices with the LAN, or as a bridge between the wireless router and another wireless router for a meshnet (the wireless router-wireless router connection can be within the LAN or can be between the LAN and WWAN).

A modem and router work in tandem to deliver you an internet connection and then grant access to your various devices. Modem vs. router: The differences between the pieces of hardware that connect ...
Routers and other network-layer devices form boundaries between broadcast domains. The notion of a broadcast domain can be compared with a collision domain, which would be all nodes on the same set of inter-connected repeaters and divided by switches and network bridges. Collision domains are generally smaller than and contained within ...
