Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).
coNCePTuaL is a domain-specific programming language for rapidly generating programs that measure the performance and/or test the correctness of networks and network protocol layers. A few lines of coNCePTuaL code can produce programs that would take significantly more effort to write in a conventional programming language.
DAPL (Direct Access Provider Library) is a transport-independent, platform-independent, high-performance API for using the remote direct memory access (RDMA) capabilities of modern interconnect technologies such as InfiniBand, the Virtual Interface Architecture, and iWARP. This is the reference implementation of that specification by the DAT Collaborative who maintain the DAPL API.
ngrep strives to provide most of GNU grep's common features, applying them to the network layer. ngrep is a pcap-aware tool that will allow you to specify extended regular or hexadecimal expressions to match against data payloads of packets. It currently recognizes IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw across Ethernet, PPP, SLIP, FDDI, Token Ring, and null interfaces, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.
GASNet (Global-Address Space Networking) is a language-independent low-level networking layer that provides network-independent, high-performance communication primitives tailored for implementing parallel global-address space SPMD languages such as UPC, Titanium, and Co-Array Fortran. The interface is primarily intended as a compilation target and for use by runtime library writers (as opposed to end users), and the primary goals are high performance, interface portability, and expressiveness.
Howl is a cross platform implementation of the Zeroconf zero configuration networking standard. It includes daemons and a client side SDK for registering, browsing, and resolving network services, and assigning link local IP addresses without a DHCP server. On Windows 2000/XP, it includes a sidebar in Internet Explorer that allows users to browse zeroconf-enabled Web and FTP servers.
NRL OLSR is the NRL's implementation of the OLSR ad-hoc mobile network routing protocol, using RFC 3626 packet formats. It supports IPv4 and IPv6. Support for Ethereal and NS2 exists but may not be current. NRL's implementation is derived from INRIA's OLSR software router, which is also available.
MPI Parallel Environment (MPE) is a software package for MPI (Message Passing Interface) programmers. It provides users with a number of useful tools for their MPI programs such as a set of profiling libraries that collect information about the behavior of MPI programs, graphical trace file analyzers, serializers, type checkers, collective operations validators, etc.
