By Douglas E. Comer
Machine Networks and Internets is suitable for all introductory-to-intermediate classes in laptop networking, the web, or net functions; readers want no heritage in networking, working structures, or complex arithmetic.
Leading networking authority Douglas Comer provides a wide-ranging, self-contained journey of the ideas, ideas, and applied sciences that permit today’s net to aid purposes starting from net looking to telephony and multimedia. This 5th version has been completely reorganized, revised, and up to date: it contains wide new insurance of themes starting from instant protocols to community functionality, whereas lowering or taking out assurance of older protocols and applied sciences. Comer starts off through illuminating the purposes and amenities provided by way of today’s net. subsequent, he systematically introduces the underlying community applied sciences and protocols that cause them to attainable: low-level information communications; packet switching, LAN, and WAN applied sciences; and net protocols comparable to TCP, IP, UDP, and IPv6. With those thoughts and applied sciences validated, he introduces a number of of an important modern concerns confronted through community implementers and bosses, together with caliber of carrier, web telephony, multimedia, community defense, and community administration. Comer has rigorously designed this publication to help either top-down and bottom-up instructing techniques. scholars desire no historical past in working structures, and no subtle math: Comer is predicated all through on figures, drawings, examples, and analogies, no longer mathematical proofs.

One of the primary reasons for the success of TCP/IP standards lies in their tolerance of heterogeneity. Instead of attempting to dictate details about packet switching technologies, such as packet sizes or the method used to identify a destination, TCP/IP takes a virtualization approach that defines a network-independent packet and a network-independent identification scheme, and then specifies how the virtual packets are mapped onto each possible underlying network. Interestingly, TCP/IP’s ability to tolerate new packet switching networks is a major motivation for the continual evolution of packet switching technologies.
