xl2tpd is an implementation of the Layer 2 Tunnelling protocol (RFC 2661).
L2TP allows you to tunnel PPP over UDP. Some ISPs use L2TP to tunnel user
sessions from dial-in servers (modem banks, ADSL DSLAMs) to back-end PPP
servers. Another important application is Virtual Private Networks where
the IPsec protocol is used to secure the L2TP connection (L2TP/IPsec,
RFC 3193). The L2TP/IPsec protocol is mainly used by Windows and
Mac OS X clients. On Linux, xl2tpd can be used in combination with IPsec
implementations such as Openswan.
Host Identity protocol on Linux is an implemetation of the Host Identity protocol (HIP) and the related architecture. HIP is a proposal to change the TCP/IP stack to securely support mobility and multi-homing. Additionally, it provides for enhanced security and privacy and advanced network concepts, such as moving networks and mobile ad hoc networks. HIP is "cool", which means that as a mobile VPN solution, when your network interfaces go up or down, there is no need to re-establish a secure tunnel.
This the first release of a free TCP/IP/PPP protocol stack for the uC/OS Real-Time Operating System. As a first release it s still rather rough and very much larger than desired however it is working well in an embedded product and therefore may be useful to others. Much of the code is ported from public sources including BDS Lite and KA9Q (and its derivatives) and carries copyright notices from those sources. Essentially TCP is based on KA9Q but with ideas from BSD, IP is a simple implementation supporting BSD structures, ICMP is ported from BSD, and PPP is ported from the BSD version of the distribution common to BSD, Linux, and many other systems
jWAP is a Java implementation of the Wireless Application protocol (WAP).
It includes Wireless Session protocol (WSP) and Wireless Transaction
protocol (WTP). Additionally, jWAP contains a WAP Binary XML (WBXML)
Parser/Generator. It requires Java >= 1.2.
WAP browser is based on the Wireless Application protocol web browser, WAP1.3 will enable mobile phones and other devices connected to the Internet, browse the Internet website.
