Technical specialists and network managers explain how to design, build, and operate a large global Internet Protocol network, and overview many of the transport and access components. After discussing carrier-scale networks and IP networks in general, they look at scaling issues, peering with other networks, and other practical building and maintaining issues; the connections between the points of presence of an Internet provider and their customers; and some less technical aspects of operations. Issues of network management are discussed throughout as appropriate. Annotation copyrighted by Book News, Inc., Portland, OR

Internetworking Protocol (IP) addresses are the unique numeric identifiers required of every device connected to the Internet. They allow for the precise routing of data across very complex worldwide internetworks. The rules for their format and use are governed by the Internet Engineering Task Force (IETF) of the The Internet SOCiety (ISOC). In response to the exponential increase in demand for new IP addresses, the IETF has finalized its revision on IP addressing as IP Version 6, also know as IPng (ng = Next Generation). Key hardware vendors such as Cisco and major Internet Service Providers such as America Online have already announced plans to migrate to IP Version 6.IP address allocation within an organization requires a lot of long-term planning. This timely publication addresses the administrator and engineer's need to know how IP 6 impacts their enterprise networks. - Easy-to-read, light technical approach to cellular technology - Ideal for companies planning a phased migration from IP 4 to IP 6 - Timely publication: The IETF standard was finalized in early 1999 and will begin to be implemented in late 1999/2000. The current IP Version 4 address set will be exhausted by...
