Open-iSCSI project is a high performance, transport independent, multi-platform implementation of RFC3720.
an open source implementation of the IEEE 802.1x protocol. It can be used in *any* scenario where one can abstract out the notion of a port. It requires entitie(s) to play three roles in the authentication process: that of an supplicant, an authenticator and an authentication server
Open5066 is an open source implementation of NATO NC3A STANAG 5066 protocol stack for HF radio communications. It aims to implement all of SIS (Annex A), DTS (Annex C), and some of the application layer (Annex F) functionality such as HMTP.
The "Open Device Monitoring and Tracking Protocol", otherwise known as OpenDMTP?, is a protocol and framework that allows bi-directional data communications between servers and devices (clients) over the Internet and similar networks. OpenDMTP is particularly geared towards Location-based information (LBS) such as GPS, as well as temperature and other data collected in remote-monitoring devices.
OpenOTP is an implementation of the HOTP protocol using a ZeitControl Cardsystems ZC3.9 BasicCard and standalone balance reader, standalone Spyrus PAR2 (Personal Access Reader), or PCSC-Lite supported smart card reader.
ORTE is an open source C implementation of the Object Management Group (OMG) Data Distribution Service (DDS) and RTPS protocol.
Protocol for SYnchronous Conferencing: not only allows peer-to-peer instant messaging but also brings multi-user chat into a distributed dimension
an implementation of OLSR in the Python language, plus various tools
a C++ implementation of the OLSR protocol for mobile wireless ad hoc networks. It is meant to be enhanced with QoS features from the QOLSR research group
Resilient Streaming Protocol
The Resilient Streaming Protocol (RSP) is a one-way IP/UDP based media streaming protocol that was developed initially to provide high reliability audio streaming between the mountainchill.com internet radio station's rural studios and shoutcast servers.
a user-space implementation of the Layer 2 Tunneling Protocol (RFC 2661)
Remote SPeaker Protocol: enables you to control speakers in multiple PCs via udp broadcasts
RTnet is an Open Soure hard real-time network protocol stack for Xenomai and RTAI (real-time Linux extensions). It makes use of standard Ethernet hardware and supports several popular NIC chip sets, including Gigabit Ethernet. Moreover, Ethernet-over-1394 support is available based on the RT-FireWire protocol stack.
Stream Control Transmission Protocol: a reliable, message-oriented, multihomed transport protocol. Developed by the IETF SIGTRAN working group to transport SS7 over IP, it is now the third general-purpose transport developed by the IETF
both a protocol definition and a software implementation of a new encryption layer for IPv4. It makes use of symmetric cryptography for encrypting the whole traffic on a network
SLRRP Implementation Project
SLRRP is the Simple Lightweight RFID Reader Protocol, an individual submission Internet-Draft to the IETF for a protocol to convey configuration, control, status, and tag information between controllers and readers in an IP-based RFID network.
T/TCP for Linux
an experimental extension for TCP, the T/TCP (TCP for Transactions) standard
The Linux PTP Project
The Linux PTP Project is an implementation of the Precision Time Protocol (PTP) according to IEEE standard 1588 for Linux.
a protocol that enables a client piece of software to securely tell a server process on a remote machine to execute a predetermined command. tumbler is similar to port knocking and is designed so that a remote user can securly and steathily enable and disable server processes, or open and close firewall holes on a computer connected to the Internet
an UCSPI protocol for the local communication domain. Provides selective access to privileged server processes to local users without setuid programs
a stripped down implementation of the TCP/IP protocol stack with a very low overhead
UniverSAl playGround for Ipv6: works to deliver the production quality IPv6 protocol stack for the Linux system, tightly collaborating with WIDE Project, KAME Project and TAHI Project
Virtual Network Address Translation
a novel architecture that allows transparent migration of end-to-end live network connections associated with various computation units. Such computation units can be either a single process, or a group of processes, or an entire host. It virtualizes network connections perceived by transport protocols so that identification of network connections is decoupled from stationary hosts. Such virtual connections are then remapped into physical connections to be carried on the physical network using network address translation
an implementation of the 802.1Q VLAN protocol for Linux
an implementation of VRRPv2 as specified in rfc2338. VRRP is a protocol which elects a master server on a LAN. If the master fails, a backup server takes over
Very Simple Control Protocol: a project that connect tiny little things and let them work together in a very easy way. Its use are intended for SOHO (Small Office Home automation) but it can be used in many other areas
a proposed Internet protocol that allows Internet server programs know if a particular (dynamically allocated) IP address is currently allocated to a known (trusted) user and, optionally, the identity of the said user
The eXtensible Binary Universal Protocol (XBUP) project is an attempt to design a general binary communication protocol and file format.
