کتاب Computer Networks and Internets

کتاب Computer Networks and Internets

Computer Networks and Internets is appropriate for all introductory-to-intermediate courses in computer networking, the Internet, or Internet applications; readers need no background in networking, operating systems, or advanced mathematics.

Leading networking authority Douglas Comer presents a wide-ranging, self-contained tour of the concepts, principles, and technologies that enable today’s Internet to support applications ranging from web browsing to telephony and multimedia.

This Fifth Edition has been thoroughly reorganized, revised, and updated: it includes extensive new coverage of topics ranging from wireless protocols to network performance, while reducing or eliminating coverage of older protocols and technologies.

Comer begins by illuminating the applications and facilities offered by today’s Internet. Next, he systematically introduces the underlying network technologies and protocols that make them possible: low-level data communications; packet switching, LAN, and WAN technologies; and Internet protocols such as TCP, IP, UDP, and IPv6. With these concepts and technologies established, he introduces several of the most important contemporary issues faced by network implementers and managers, including quality of service, Internet telephony, multimedia, network security, and network management.

Comer has carefully designed this book to support both top-down and bottom-up teaching approaches. Students need no background in operating systems, and no sophisticated math: Comer relies throughout on figures, drawings, examples, and analogies, not mathematical proofs.

IP for 3G

IP for 3G

What is an ‘all-IP’ network? What difference will IP networkingmake to 3G services?

Third Generation (3G) mobile offers access to broadband multimediaservices – and in the future most of these, even voice and video,will be IP-based.

However 3G networks are not based on IPtechnologies, rather they are an evolution from existing 2Gnetworks.

Much work needs to be done to IP QoS and mobilityprotocols and architectures for them to be able to provide thefunctionality 3G requires.

IP for 3G gives a comprehensive overview of 3G networkingfunctionality and examines how IP protocols can be developed toprovide some of the basic building blocks of a mobile system(mobility, QoS and call control)
Features:

 Clear explanation of how 3G works at the network level. 

Review of IP protocol and architectural principles.

 Extensive review, classification and analysis of IP mobilityprotocols – macro and micro- including IPv6.

 Analysis of IP QoS protocols and proposed solutions for mobilenetworks.

 Tutorial on SIP (Session Initiation Protocol) and how SIP can beused for multimedia session control.

 Description of latest UMTS developments – including Release5.

Discussion of 4G networks – what does 4G mean?

IP for 3G will appeal to mobile telecommunications and networkengineers who want to know about future developments as well assystem designers and developers.

Students and academics onpostgraduate courses related to telecommunications, especially 3Gnetworking or IP protocols, will find this text ideal supplementaryreading, only assuming a general knowledge of GSM and generalnetworking principles.
