Data may be queued before being transmitted due to other user's data that's also queueing for transmission. O c. Resources are used on demand, not reserved in advance. d. This technique was the basis for the telephone call switching during the 20th century and into the beginning of this current century. e. This technique is used in the Internet. f. Congestion loss and variable end-end delays are possible with this technique. g.

Choose one the following two definitions that makes the correct distinction between routing versus forwarding. Flag question Select one: O a. Routing is the local action of moving arriving packets from router's input link to appropriate router output link, while forwarding is the global action of determining the source-destination paths taken by packets. O b. Forwarding is the local action of moving arriving packets from router's input link to appropriate router output link, while routing is the global action of determining the source-destination paths taken by packets.
