Next Generation TCP/IP Stack in Windows Vista and Windows Server "Longhorn"
Microsoft® Windows® Vista™ Beta 1 and Windows Server™ "Longhorn" Beta 1 include a new implementation of the TCP/IP protocol suite known as the Next Generation TCP/IP stack. The TCP/IP protocol stack provided with Windows XP and Windows Server 2003 was originally designed in the early 1990s and was modified and enhanced over time to meet the needs of home and enterprise users. The Next Generation TCP/IP stack in Windows Vista and Windows Server "Longhorn" is a complete redesign of TCP/IP functionality for both Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) that meets the connectivity and performance needs of today's varied networking environments and technologies.
