IPv6 Essentials

Więcej o książce

Pv6 Essentials covers all aspects of IPv6, the protocol set to play a crucial role in future IP-based networks. As IPv4, developed nearly 30 years ago, becomes outdated and struggles to meet modern demands, IPv6 emerges as its evolution. Both protocols are expected to coexist for years, supported by various interoperability and transition mechanisms. This book addresses key topics, including the IPv6 header, extension headers, and the 128-bit address format; ICMPv6 functions like neighbor and router discovery, autoconfiguration, Path MTU discovery, and multicast group management; security features within IPv6 and the IPSEC framework; and QoS elements and architectures. It also explores sample network designs, Mobile IPv6, and routing protocols such as RIPng, OSPFv3, BGP, and IS-IS, along with upper-layer protocols like DHCP, DNS, and HTTP. Additionally, it provides insights into interoperability and transition scenarios, along with a quick-start guide for implementing IPv6 on various operating systems, including Sun Solaris, Linux, and Windows. This well-structured introduction is valuable for network professionals, administrators, managers, and executives, illustrating IPv6's features and practical applications, including packet trace files. The book also offers market insights, IPv6 address space registration guidance, and advice on integrating IPv6 into corporate network strategies.
