TCP/IP for Microsoft® Windows® CE allows devices to participate as peers and servers on local area networks (LANs) and remote networks.

OS Design Information

The following table shows operating system design information for TCP/IP.

Element	Information
Dependencies	Winsock, FormatMessage API, and Full C Runtime
Hardware considerations	None

Modules and Components

The following table shows the components and modules that implement TCP/IP.

Item	Module	Component
TCP/IP support	tcpstk	None

TCP/IP Implementation Considerations

You can include the TCP/IP Catalog item in your OS design by choosing item from the Catalog. Choosing this Catalog item sets the appropriate Sysgen variable for enabling TCP/IP.

The following table shows the Sysgen variable that enables TCP/IP.

Sysgen variable	Description
SYSGEN_TCPIP	When this variable is set, TCP/IP is included in the run-time image. TCP/IP is a set of protocols that co-operating computers and devices can use to share resources across a network. It includes support for IP, ARP, ICMP, IGMP, TCP, UDP, name resolution and registration, and DHCP. This TCP/IP is available in both headless and display-based devices. Note This Sysgen variable only adds TCP/IPv4 to your OS design. To include TCP/IPv6, you must also set the SYSGEN_TCPIP6 variable. For more information about this Sysgen variable, see IPv6 Overview.
SYSGEN_IPHLPAPI	When this variable is set, the IP Helper API is included in the run-time image. The IP Helper API is a set of functions that gives you the ability to manage TCP/IP services, such as ARP, Route, and DHCP. The IP Helper API can be used by applications to query for network notifications and network statistics. It is available in both headless and display-based devices. For more information, see Internet Protocol Helper APIs.
