Windows Server 2003 TCP/IP supports the following standard features:
-
Ability to bind to multiple network adapters with different media types
-
Logical and physical multihoming
-
Internal IP routing capability
-
Internet Group Management Protocol (IGMP) version 3 (IP multicasting)
-
Duplicate IP address detection
-
Multiple default gateways
-
Dead gateway detection
-
Automatic Path Maximum Transmission Unit (PMTU) discovery
-
Internet Protocol security (IPsec)
-
Quality of Service (QoS)
-
ATM Services
-
Virtual Private Networks (VPNs) with the Point-to-Point Tunneling Protocol (PPTP) and the Layer Two Tunneling Protocol with IPsec (L2TP/IPsec)
Performance Enhancements
In addition, Windows Server 2003 TCP/IP has the following performance enhancements:
-
Protocol stack tuning, including increased default window sizes and new algorithms for high-delay and high-loss links, which increases throughput
-
TCP-scalable window sizes (described in RFC 1323)
-
Selective acknowledgments (SACK) (described in RFC 2018)
-
TCP fast retransmit and fast recovery (described in RFC 2581)
-
Round Trip Time (RTT) and Retransmission Timeout (RTO) calculation improvements
-
Improved performance for management of large numbers of connections
-
Hardware task offload mechanisms including checksum offload and large send offload (LSO)
Services Available
The Windows Server 2003 operating system provides the following TCP/IP-related services:
-
Dynamic Host Configuration Protocol (DHCP) client and server and DHCP Relay Agent (with the Routing and Remote Access service)
-
In the absence of a DHCP server, Automatic Private IP Addressing (APIPA) is used
-
Windows Internet Name Service (WINS), a NetBIOS name client and server
-
Domain Name System (DNS) client and server, including support for DNS dynamic updates
-
Dial-up support using the Point-to-Point Protocol (client and server) and Serial Line Internet Protocol (client only)
-
PPTP and L2TP/IPsec, used for remote access and site-to-site VPN connections
-
TCP/IP network printing (client only with the Lpr.exe and Lpq.exe tools)
-
SNMP agent
-
NetBIOS interface
-
Network Location Service
-
Windows Sockets version 2 (Winsock2) interface
-
Remote Procedure Call (RPC) support
-
Network Dynamic Data Exchange (NetDDE)
-
Computer browsing (My Network Places) across IP routers
-
Reliable multicast with the Pragmatic General Multicast (PGM) protocol
-
Basic TCP/IP connectivity utilities, including: finger, ftp, rcp, rexec, rsh, telnet, and tftp
-
Server and client software for simple network protocols, including: Character Generator, Daytime, Discard, Echo, and Quote of the Day
-
Routing Information Protocol (RIP) listener (for Windows XP Professional) and RIP and Open Shortest Path First (OSPF) (with the Routing and Remote Access service)
-
Network Address Translator (NAT) capabilities using either the Internet Connection Sharing (ICS) or the NAT/Basic Firewall routing protocol component of the Routing and Remote Access service
-
Stateful firewalling capabilities using either the Internet Connection Firewall (for Windows Server 2003 with no service packs installed), Windows Firewall (for Windows Server 2003 Service Pack 1), or the NAT/Basic Firewall routing protocol component of the Routing and Remote Access service
-
Multicast forwarding and IGMP router and proxy capabilities with the Routing and Remote Access service
-
TCP/IP management and diagnostic tools, including: arp, ipconfig, nbtstat, netsh, netstat, ping, pathping, route, nslookup, and tracert
New Features for Windows Server 2003 TCP/IP
The features and improvements of TCP/IP that are new for Windows Server 2003 include the following:
-
Windows Server 2003, Windows XP with Service Pack 1, and Windows XP with Service Pack 2 now include a production-quality IPv6 protocol stack. For more information about IPv6, see Windows Server 2003 Help and Support Center or the Microsoft Windows IPv6 Web site (http://www.microsoft.com/ipv6).
-
Auto-negotiation of RFC 1323 options (window scaling and TCP timestamps).
-
Default support of network interface cards (NICs) providing large send offload (LSO) and checksum offload.
-
IGMP version 3.
-
Reliable multicast with PGM.
-
Alternate configuration.
-
Automatic determination of the interface-related and default route metrics.
The table below lists features and the operating system versions that they are present in as a reference. Features are described in more detail throughout this paper.
