For (71) service, we need a virtual-circuit subnet. Let us see how that works. The idea behind virtual circuits is to avoid having to choose a new (72) for every packet sent. Instead, when a connection is established, a route from the (73)machine to the destination machine is chosen as part of the connection setup and stored in tables inside the (74) That route is used for all traffic flowing over the connection, exactly the same way that the telephone system works. When the connection is released, the virtual circuit is also terminated. With connection-oriented service, each packet carries an (75) telling which virtual circuit it belongs to.A．connectionlessB．connection-orientedC．datagramD．telegram

● A glue that holds the whole Internet together is the network layer protocol,(71). Unlike most older network layer protocols, it was designed from the beginning with internetworking in mind. Its job is to provide a -(72) way to transport datagrams from source to destination, without regard to whether these machines are on the same network or whether there are other networks in between them.Communication in the Internet works as follows. The (73)layer takes data streams and breaks them up into datagrams. Each datagram is transmitted through the Internet, possibly being fragmented into smaller units as it goes. When all the pieces finally get to the destination machine, they are reassembled by the(74) layer into the original datagram. This datagram is then handed to the transport layer, which inserts it into the receiving process' input stream.An IP datagram consists of a header part and a text part. The header has a (75) part and a variable length optional part.(71) A. IP (Internet Protocol)B. IP (Interworking Protocol)C. TCP (Transport Control Protocol)D. TCP (Transfer Communication Protocol)(72) A. best-qualityB. quality-guaranteedC. connection-orientedD. best-efforts(73) A. data linkB. transportC. networkD. application(74) A. data linkB. transportC. networkD. application(75) A. 40-byte fixedB. 64-byte fixedC. 20~64 bytes variableD. 20-byte fixed

A virtual (71) network, or VPN, is an encrypted connection over the Internet from a device to a network. The encrypted connection helps ensure that sensitive data is safely (72). It prevents (73) people fromeavesdropping on the traffic and allows the user to conduct work remotely. Traffic on the virtual network is sent securely by establishing an encrypted connection across the Internet known as a (74).A remote access VPN securely connects a device outside the corporate office. A site-to-site VPN connects the corporate office to branch offices over the Internet. Site-to-site VPNs are used when distance makes it impractical to have direct network connections between these offices. Think of site-to-site access as (75) to network.
