Learn which computers are on each side of the bridge By reading the source addresses on incoming frames and recording this information in forwarding tables Data link layer devices Connecting similar type of networks But they can connect different types of cable Not popular anymore Losing market share to layer 2 switches as the latter become cheaper and more powerfulĬonnect LANS with different data link layer, but the same network layer protocol Allows different types of cabling Perform more processing than bridges or layer 2 switchesĩ Routers (Cont.) Operations Compared to Bridges Network cable Functions in the same way as in LANs Optical fiber - more commonly chosen (provides higher data rates) Hardware devices Computers or special purpose devices used for interconnecting networks Bridges Routers Gatewaysĭevice Operates at Packets Physical Layer Data Link Layer Network Layer Bridge Data Link Layer Filtered using data link layer addresses Same or Different Same Same Router Network Layer Routed using network layer addresses Same or Different Same or Different Same Gateway Network Layer Routed using network layer addresses Same or Different Same or Different Same or DifferentĬonnect LANs with the same Data Link and same Network layers Allows different types of cabling Operate in a similar way to layer 2 switches (learning bridges)ħ Learning Bridges Operate in a similar way to layer 2 switches: Making information transfer possible between departments Use high speed circuits to connect LANs Provide connections to other backbones, MANs, and WANs Sometimes referred to as An enterprise network A campus-wide network
