Exam 9: Introduction to Metropolitan Area Networks and Wide Area Networks

When an application is simply observing its own throughput and not relying on any special types of signals coming from the network, this is called ____ congestion control.

Wide area networks carry both data and voice.

Some congestion control methods are based on simple techniques such as the flow control methods.

With ____ routing, routing tables are created once, typically when the network is installed, and then never updated again.

The two types of packet-switched networks are the datagram and the ____.

One disadvantage of distributed routing is related to the problems that arise if the routing tables need to be updated.

A network that is connected in a ____ is one in which neighbors are connected only to neighbors.

A ____ application does not guarantee the delivery of any information or data.

A network that expands beyond a metropolitan area is a ____ area network.

Some MAN topologies are based on a ring.

Wide area networks share a few characteristics with local area networks.

MANs are almost exclusively ____ networks, and thus capable of supporting data rates into the tens of millions and hundreds of millions of bits per second.

____ applications do not negotiate a connection, and the transfer of data is rarely, if ever, acknowledged.

With ____, when a frame relay router experiences congestion, it sends a congestion signal forward to the destination station, which in turn tells the originating station to slow down the transfer of data.

____________________ states that each node takes the incoming packet and retransmits it onto every outgoing link.

A(n) ____________________ is a device that allows one or more stations to access the physical network and is a transfer point for passing information through the network.

How is routing through a wide area network accomplished?

When all the routing information is in one place, it is difficult to make updates to the routing information.

A network that expands into a metropolitan area and exhibits high data rates, high reliability, and low data loss is called a(n) ___________________________________.

The SONET network topology is a ____.
