Exam 8: ATM Technologies

Which type of traffic has the highest tolerance for delay?

One of the disadvantages of a PVC is that the circuit must be created and maintained manually.

A value of zero in the Cell Loss Priority field in an ATM header indicates that the cell has high priority and cannot be dropped.

SMDS cannot be transported over ATM.

In ATM, like Ethernet and token ring networks, all connected devices see all network traffic.

What is an SPVC? What is one advantage and one disadvantage of an SPVC?

Latency is the amount of time it takes for the switch to process and forward a cell.

In service interworking the ATM end node between the frame relay and the ATM network does not significantly change the encapsulation of the frame relay frame.

ATM is able to transport a wide range of information transmissions at high speeds by dividing data into equal-sized cells and attaching a header to ensure that each cell is routed to its destination.

What does QoS stand for, and how is it related to ATM?

Like some other WAN technologies, ATM uses virtual circuits, which are called ____.

ATM continues to have a strong base as a ____ technology.

For the voice attribute, the ATM throughput can be described as ____.

An ATM cell has ____ bytes of payload information.

The Transmission Convergence sublayer does not ____.

The ATM Group is a consortium of hardware vendors, telecommunications service providers, and users who work with the ITU-T on specifications for LAN and WAN applications of ATM.

Cells, like packets, carry a fixed-length data payload.

For constant bit-rate service for connection-oriented voice and video, you use the ____ service type.

In which layer do you find the SAR and Convergence sublayers? What are their functions?

The overall goal of managing ATM LANs and WANs is to monitor network congestion and flow control for optimal traffic patterns.
