Exam 9: Wan Technology and Protocols

Each packet contains some portion of the user data plus control information needed for proper functioning of the network.

Circuit switching and packet switching are traditional approaches to wide area network design.

Flexibility,resource sharing,robustness,and responsiveness are all advantages of ________ switching.

With ________ a dedicated path is established between two stations for communication.

The ________ element represents the functions and hardware needed to connect digital devices such as data processing devices and digital telephones to the network.

Dynamic use of bandwidth is utilized with ________.

The function of the ________ is to provide a transparent signal path between any pair of attached devices.

Priorities cannot be used with packet switching.

The ________ level deals with the physical interface between an attached station and the link that attaches that station to the packet switching node.

In the ________ approach in packet switching each packet is treated independently with no reference to packets that have gone before.

Communication via circuit switching involves three phases: circuit establishment,data transfer and ________.

Node-node links are usually multiplexed using either frequency division multiplexing or time division multiplexing.

A ________ switch is one in which the signal paths are physically separate from one another.Each connection requires the establishment of a physical path through the switch that is dedicated solely to the transfer of signals between the two endpoints.

Elaborate algorithms are used to cope with the time delay and overhead penalties of network operation in a packet switching network.

The term ________ refers to the logical connection between two stations through the network.

________ switching involves the partitioning of a lower speed bit stream into pieces that share a higher speed stream with other bit streams.The individual pieces are manipulated by control logic to route data from input to output.

Analog data must be converted to digital before transmission for packet switching.

Circuit switching connections ________.

Circuit switching was developed to handle ________ traffic.

A ________ is a general purpose computer running specialized software that turns it into a smart phone switch.These cost significantly less than traditional circuit switches and can provide more functionality.
