Quiz 9

__ routing involves storing all the routing information at one central location.

Centralized

__ and virtual circuit networks require path setup time and cannot dynamically reroute packets should a network problem occur.

Circuid-switched

__ avoids congestion by requiring users to negotiate with the network regarding how much traffic they will be sending, or what resources the network must provide to satisfy the user's needs before the user sends any data.

Connection admission control

A classic algorithm that calculates at least-cost path through a network is __ algorithm.

Dijkstra's least-cost

Almost all MANs are based on one of two basic forms of supporting technology: __ or Ethernet.

SONET

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

UNKNOWN

__ area networks can cover large geographic distances, including the entire Earth.

Wide

When a node on a wide area network __ network transmits its data , the data is received by all the other nodes.

broadcast

A __ network is the only network that offers a dedicated path.

circuit-switched

The three basic types of subnetworks are __, packet-switched, and broadcast.

circuit-switched

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

connectionless

One of the primary advantages of __ routing is the fact that no single node is responsible for maintaining all routing information.

distributed

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

fiber-optic

A network limit, called the __, can be placed on how many times any packet is copied.

hop limit

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 __ implicit congestion control.

implicit

A __ area network is typically confined to a single building or a couple floors within one building.

local

A wide area network connects its workstations through the use of a __ design and requires routing to transfer data across the network.

mesh

When a network or a part of a network becomes so saturated with data packets that packet transfer is noticeably impeded, __ occurs.

network congestion

All wide area networks are collections of at least two basic types of equipment: a station and a __.

node

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

virual circuit
