Traditional IP packet forwarding analyzes the （ ）IP address contained in the network layer header of each packet as the packet travels from its source to its final destination. A router analyzes the destination IP address independently at each hop in the network. Dynamic （ ）protocols or static configuration builds the database needed to analyze the destination IP address （the routing table）.The process of implementing traditional IP routing also is called hop-by-hop destination-based （ ）routing. Although successful，and obviously widely deployed，certain restrictions，which have been realized for some time，exist for this method of packet forwarding that diminish its （ ）. New techniques are therefore required to address and expand the functionality of an IP-based network infrastructure.This first chapter concentrates on identifying these restrictions and presents a new archiecture，known as multiprotocol （ ）switching，that provides solutions some of these restrictions.问题1选项A.datagramB.destinationC.connectionD.service问题2选项A.routingB.forwardingC.transmissionD.management问题3选项A.anycastB.muticastC.broadcastD.unicast问题4选项A.reliabilityB.flexibilityC.stabilityD.capability问题5选项A.costB.castC.markD.label
