Chapter 1:
R3: Standards are important because they assure that projects or work are done in an efficient manner that meet implicit instructions are follow rules that generally used in an a particular field.
R4:
- Dial-up : home
- DSL: home or enterprise
- Cable to HFC: home
- 100 Mbps switched Ethernet: enterprise
- Wireless LAN: mobile
- Cellular: mobile
R22: Error control, flow control, segmentation and reassembly, multiplexing, and connection setup. It is definitely possible for some of these tasks to be performed by two or more layers.
Chapter 2:
R1:
- e-mail : SMTP
- web: HTTP
- streaming multimedia: HTTP
- network news: FTP
- remote terminal access: Telnet
Chapter 5:
R3- The link layer protocol can also offer framing and link access (MAC) services to the network layer. Two services that have corresponding services in IP/TCP are error detection and recovery.
R4-
Collision will not be a problem because the transmission time is less than the propagation delay, so the channel will clear by the time the transmission finishes and the next propagation starts
R9-
MAC address space - 48 bits - 2^48
IPv4 - 32 bits - 2^32
IPv6 - 128 bits - 2^128
Chapter 4:
R2: Datagram-based network layer: forwarding; routing. Additional function of VC-based network layer: call setup.
R3: Forwarding deals with moving a packet from a router's input link to the appropriate output link. Routing deals with determining the end-to-end paths between sources and destinations.
R12: Yes. 1 IP address is assigned per router interface
R4:
- Dial-up : home
- DSL: home or enterprise
- Cable to HFC: home
- 100 Mbps switched Ethernet: enterprise
- Wireless LAN: mobile
- Cellular: mobile
Chapter 3:
R4: An application developer may want to use UDP or TCP because UDP is faster and will not throttle the sending rate because of congestion. Also reliable data transfer may not be needed.
R6: The application developer can build reliable data...
