Overview of Dedicated Circuits

Technology	Min BW	Max BW	Advantages	Disadvantages
Frame Relay or ATM	56kbps	384k - 45Mbps	usually no mileage charges easy to scale high reliability	wide variance of CIR from carrier possible latency in cloud relatively high cost from carrier
HDLC	56kbps	n * 1.54Mbps	lowest latency best performance easy to scale high reliability	highest cost from carrier mileage charges
ISDN	56kbps	~384kbps	very flexible capabilities costs less than HDLC & Frame Relay easy to scale	multichannel has reduced efficiency not available everywhere
xDSL	64kbps	7Mbps	high BW cheap from carrier good for "bursty" traffic patters	distance sensitive limited availability large variance in latency low or no CIR low priority traffic/repair
