Bandwidth refers to the width of a communications channel, and it may be helpful to envision bandwidth as a hose or pipe that carries data communications instead of water. Comparatively a communications channel (such as a T1 line) could be said to have a wide bandwidth, while a lower-speed communications channel (such as a 56 Kb dial-up line) could be said to have a narrow bandwidth.
Bandwidth is typically expressed in bits-per-second (bps) in the digital world. With recent advances in performance, bandwidth speeds may now be expressed in Mbps (megabits per second) or Gbps (gigabits per second).
The A10 Networks' EX Series is a robust bandwidth management appliance. (See "Bandwidth Management" for details.) Both the AX Series and EX Series feature high throughput levels to support high bandwidth requirements.
