Data networks are telecommunications networks that are installed and operated for information exchange between data communication devices such as computers and voice gateways. Although data networks can transfer any type of digital media (voice, data or video), the type of network, services used and optional configurations can dramatically affect the performance of data services. This book provides a functional description of the key data network parts including hubs, routers, bridges and gateways. You will discover the differences between personal area networks (PANs), premises distribution networks (PDNs), local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs). The basic operation of Ethernet is provided along with how Ethernet has evolved and the different types of Ethernet systems that are available today. Discover how data networks are configured and managed using simple network management protocol (SNMP). Learn the basic operation of gateways and firewalls and how firewalls operate to protect networks from the unwanted transmission of information. The operation of different types of data systems and how they operate is explained including Ethernet, Token Ring, FDDI, PON, ATM, Frame Relay, and the Internet. Find out how data networks can be configured to allow many users to share the same data network using virtual private networks. You will lean about the common types of data services such as CBR, ABR, UBR and their typical service costs. Some of the most important topics featured are: . Functional parts of data networks . Descriptions of hubs, routers, bridges and gateways. . The differences between PAN, PDN, LAN, MAN, and WAN Networks . How Ethernet and other types of data networks operate . How packets are automatically routed in IP networks . How gateways and firewalls operate . Overviews of Ethernet, Token Ring, FDDI, PON, ATM, Frame Relay and the Internet . Introduction to virtual networks (VPNs) . Data services including CBR, ABR and UBR
