Traditionally, _____ methods of switching have been important. three We can divide today's networks into ____ broad categories. three Packet-switched networks can also be divided into ______subcategories: virtual-circuit networks and datagram networks two A ________ network is made of a set of switches connected by physical links, in which each link is divided into n channels. circuit-switched Circuit switching takes place at the ________ layer. physical In _______, the resources need to be reserved during the setup phase; the resources remain dedicated for the entire duration of data transfer phase until the teardown phase. circuit switching In _________, there is no resource allocation for a packet. datagram switching In _________, resources are allocated on demand. datagram switching In __________, each packet is treated independently of all others. datagram switching In _______ there are no setup or teardown phases. datagram switching A _________ network is a cross between a circuit-switched network and a datagram network. It has some characteristics of both. virtual-circuit We can say that a packet switch has _______ types of components. four The simplest type of switching fabric is the ______ switch. crossbar A ________ switch is a multistage switch with microswitches at each stage that route the packets based on the output port represented as a binary string. banyan In a banyan switch, for 8 inputs and 8 outputs, we have _____ stages. 3 In a banyan switch, for 8 inputs and 8 outputs, we have _____ microswitches at each stage. 4 A ________ switch combines space-division and time-division technologies to take advantage of the best of both. TST The most popular technology in time-division switching is called the _________. TSI Based on the Clos criteria, if N = 200, then n must be equal to or greater than ____. 10 Based on the Clos criteria, if N = 200, then k must be equal to or greater than ____. 19 Based on the Clos criteria, if N = 200, then the minimum number of crosspoints is greater than or equal to _______. 15,200 In a one-stage space division switch, if N = 200, the number of crosspoints is ______. 40,000 In a three-stage space division switch, if N = 200, the number of crosspoints is ______. less than 40,000 A ________ switch combines crossbar switches in several (normally three) stages multistage In _______ switching, the paths in the circuit are separated from one another spatially. time-division A switched WAN is normally implemented as a _______ network. virtual-circuit In a ________ network, two types of addressing are involved: global and local. virtual-circuit The network layer in the Internet is designed as a __________ network. datagram A switch in a datagram network uses a routing table that is based on the ______ address. destination The _______ address in the header of a packet in a datagram network normally remains the same during the entire journey of the packet. destination
