• Works on Layer 2• Forwarding based on MAC address• Logical: ”Bridge”, Hardware: Switch.• Learns what MAC address(es) is

connected to each port.→ Unicast only to correct port.

• Reduces load and risk for collisions. • Possibility for increased security.

Ethernet traffic over E1/DS1

› Proprietory protocol › Maps Ethernet frames to HDLC frames over nxE1.› Buffers on ingress/egress interfaces to handle bursts and priority.› Any E1 can be used for Ethernet transport (e.g. fixed, radio).› Independent transport of the E1s is possible.› The E1s must be kept intact on their way. No cross connection on 64 kbit/s level.
