This book is supposed to serve as a comprehensive and instructive guide through the new world of digital communication. On the physical layer optical and electrical cabling technology are described as well as wireless communication technologies. On the data link layer local area networks (LANs) are introduced together with the most popular LAN technologies such as Ethernet, Token Ring, FDDI, and ATM as well as wireless LAN technologies including IEEE 802.x, Bluetooth, or ZigBee. A wide range of WAN technologies are covered including contemporary high speed technologies like PDH and SDH up to high speed wireless WANs (WiMAX) and 4th generation wireless telephone networks LTE. Routing technologies conclude the treatment of the data link layer. Next, there is the Internet layer with the Internet protocol IP that establishes a virtual uniform network out of the net of heterogeneous networks. In detail, both versions, IPv4 as well as the successor IPv6 are covered in detail as well as ICMP, NDP, and Mobile IP. In the subsequent transport layer protocol functions are provided to offer a connection-oriented and reliable transport service on the basis of the simple and unreliable IP. The basic protocols TCP and UDP are introduced as well as NAT, the network address translation. Beside transport layer security protocols like SSL and TLS are presented. On the upmost application layer popular Internet application protocols are described like DNS, SMTP, PGP, (S)FTP, NFS, SSH, DHCP, SNMP, RTP, RTCP, RTSP, and World Wide Web.

Das globale Internet ist ein offenes Netz, das heißt nicht begrenzt und für jedermann zugänglich. Allerdings hat diese Offenheit ihren Preis: Es gibt keine zentrale Kontrolle, die z.B. Unbefugten Einblick in die Kommunikation und damit in die Privatsphäre anderer Internetnutzer verwehren würde. Um dennoch einen ausreichenden Schutz der Vertraulichkeit und Privatsphäre zu gewährleisten, müssen in eigener Verantwortung Techniken und Tools aus der Kryptografie eingesetzt werden, die Nachrichten verschlüsseln oder deren Unversehrtheit sicherstellen helfen. Die Autoren zeigen unterschiedliche Wege auf, wie der Schutz der Privatsphäre im Internet wiederhergestellt werden kann. Der Inhalt Sicherheitsziele und Bedrohungen im Internet Grundbegriffe der Kryptografie Vertraulichkeit und Verschlüsselung Authentifikation und Digitale Signaturen Public-Key-Infrastrukturen und Zertifikate Glossar sicherheitstechnischer Begriffe Die Zielgruppen Dozierende und Studierende der Informatik Informatiker, IT-Beauftragte sowie alle Internetnutzer, die sich für Sicherheitsfragen interessieren Die Autoren Prof. Dr. Christoph Meinel ist Direktor und Geschäftsführer des Hasso-Plattner-Instituts für Softwaresystemtechnik GmbH (HPI) sowie Inhaber des Lehrstuhls für Internet-Technologien und -Systeme an der Universität Potsdam. Dr. Harald Sack ist Senior-Researcher am Hasso-Plattner-Institut für Softwaresystemtechnik GmbH (HPI) an der Universität Potsdam.

Das Internet ist zu einem festen Bestandteil unseres täglichen Lebens geworden. Auf welchen technologischen Grundlagen das weltumspannende Internet arbeitet, verdeutlicht das Buch "Internetworking". In sieben Kapiteln werden dem Leser ausgehend von den physikalischen Grundlagen der Datenübertragung die Funktionsprinzipien und Technologien der lokalen Netzwerke (LANs) und der Weitverkehrsnetzwerke (WANs) veranschaulicht. Allgemein verständlich wird in den weiteren Kapiteln das dem Internet zugrunde liegende TCP/IP-Referenzmodell, sowie dessen Protokolle und zahlreichen Anwendungen vermittelt. Zusammengenommen stellt das Buch ein umfassendes Kompendium der Internet-Technologien dar, dessen praktischer Nutzen als Handbuch erhöht wird durch zahlreiche Abbildungen sowie Sachindex, Personenindex und Glossar zu jedem Kapitel.
