Acronym for bridge protocol data unit. BPDUs are data messages that are exchanged across the switches within an extended LAN that uses a spanning tree protocol topology. BPDU packets contain information on ports, addresses, priorities and costs and ensure that the data ends up where it was intended to go. BPDU messages are exchanged across bridges to detect loops in a networktopology. The loops are then removed by shutting down selected bridge interfaces and placing redundant switch ports in a backup, or blocked, state.

- BPL repeater
In Access broadband over power line (BPL) systems, a BPL repeater is a device used to boost the distance the signal can travel. broadband over power line (BPL). A typical BPL signal travels only for 1,000 to 3,000 feet down line, and a BPL repeater can be used to increase the distance the signal can […]
Short for Broadband Remote Access Server, it is the aggregation point for the subscriber traffic. It provides aggregation capabilities (e.g. IP, PPP, ATM) between the Regional/Access Network and the NSP or ASP. Beyond aggregation it is also the injection point for policy management and IP QoS in the Regional/Access Networks.
