Internetworking with TCP/IP, Volume 1: Principles, Protocols, and Architecture (6th Edition)
Douglas E. Comer
Format: PDF / Kindle (mobi) / ePub
An internationally best-selling, conceptual introduction to the TCP/IP protocols and Internetworking, this book interweaves a clear discussion of fundamentals and scientific principles with details and examples drawn from the latest technologies. Leading author Douglas Comer covers layering and packet formats for all the Internet protocols, includingTCP, IPv4, IPv6, DHCP, and DNS. In addition, the text explains new trends in Internet systems, including packet classification, Software Defined Networking (SDN), and mesh protocols used in The Internet of Things.
The text is appropriate for individuals interested in learning more about TCP/IP protocols, Internet architecture, and current networking technologies, as well as engineers who build network systems. It is suitable for junior to graduate-level courses in Computer Networks, Data Networks, Network Protocols, and Internetworking.

keep a record of bindings between IP addresses and Ethernet addresses. Second, if it has the necessary information, a switch can respond to an ARP request without broadcasting the request. Third, an Ethernet address can only change if a computer is powered down, and a switch can tell whether a computer has been powered down. Therefore, a switch can create its own cache of ARP information and can answer requests. For example, if computer A sends an ARP request for computer B, the switch can
Although a host with multiple network connections can be configured to act as a router, the resulting system may not perform as expected. 8.3 Direct And Indirect Delivery Loosely speaking, we can divide forwarding into two forms: direct delivery and indirect delivery. Direct delivery, the transmission of a datagram from one machine across a single physical network directly to another, is the basis on which all internet communication rests. Two machines can engage in direct delivery only if they
and two IP addresses I1 and I2. Is it possible for that machine to receive a datagram destined for I2 over the network with address I1? Explain. 8.5 In the above exercise, what is the appropriate response if such a situation arises? 8.6 Consider two hosts, A and B, that both attach to a common physical network, N. What happens if another host on the network sends A a datagram that has IP destination B? 8.7 Modify Algorithm 8.1 to accommodate the IPv4 source route options discussed in Chapter 7.
