Pcapy is a Python extension module that interfaces with the libpcap packet capture library. Pcapy enables Python scripts to capture packets on the network. Pcapy is highly effective when used in conjunction with a packet-handling package such as Impacket, which is a collection of Python classes for constructing and dissecting network packets.

RSerPool client/server API library for load distribution and Reliable Server Pooling (RSerPool) is the IETF's standard (RFC 5351 to RFC 5356) for a lightweight server pool and session management framework. It provides highly available pool management (that is registration handling and load distribution/balancing) by components called Registrar and a client-side/server-side API for accessing the service of a pool.

The rtptools distribution consists of a number of small applications that can be used for processing RTP data. rtpplay play back RTP sessions recorded by rtpdump rtpsend generate RTP packets from textual description, generated by hand or rtpdump rtpdump parse and print RTP packets, generating output files suitable for rtpplay and rtpsend rtptrans RTP translator between unicast and multicast networks

Ruby/DICT is an RFC 2229 compliant client-side library implementation of the DICT protocol, written in the Ruby programming language. It can be used to write clients that access dictionary definitions from a set of natural language dictionary databases.

[ excerpt from developer's web site with modifications ] The goal is to build a system capable of supporting massive concurrency (on the order of tens of thousands of simultaneous client connections) and avoid the pitfalls which arise with traditional thread and event-based approaches. SEDA is an acronym for staged event-driven architecture, and decomposes a complex, event-driven application into a set of stages connected by queues. This design avoids the high overhead associated with thread-based concurrency models, and decouples event and thread scheduling from application logic. By performing admission control on each event queue, the service can be well-conditioned to load, preventing resources from being overcommitted when demand exceeds service capacity. SEDA employs dynamic control to automatically tune runtime parameters (such as the scheduling parameters of each stage), as well as to manage load, for example, by performing adaptive load shedding. Decomposing services into a set of stages also enables modularity and code reuse, as well as the development of debugging tools for complex event-driven applications.

The SIP Scenario Generator creates SIP Call Flows or SIP scenario diagrams, in html format, of SIP messages from ethernet capture files. SIP Scenario Generator shows the actual call processing trace in a format that is easily understood using browser technology. Clicking on a sip message hyperlink displays the contents of the traced SIP message. The SIP Scenario Generator is a useful tool for SIP professionals, engineers, administrators, educators, etc.

Tcpillust - A graphical TCP connection analysis tool Tcpillust takes tcpdump file(s) specified on the command line and draw pictures like figures in the ``TCP/IP Illustrated'' series.

Skstream is an iostream based C++ socket library. It is ideally suited for use as the underlying transport for Atlas-C++, and has been well tested and debugged. It was first discovered for WorldForge when it was used in UClient and has since been packaged up as its own library for use on other WorldForge projects. The code was originally written by Rafael Guterres Jeffman who is not involved with the project but we have extensively rewritten it, and added new features such as IPv6 support and Unix domain sockets. It now maintained for WorldForge by Al Riddoch and others.

SubNetCalc is an IPv4/IPv6 subnet address calculator. For given IPv4 or IPv6 address and netmask or prefix length, it calculates network address, broadcast address, maximum number of hosts and host address range. The output is colourized for better readability (e.g. network part, host part). Also, it prints the addresses in binary format for better understandability. Furthermore, it can identify the address type (e.g. multicast, unique local, site local, etc.) and extract additional information from the address (e.g. type, scope, interface ID, etc.). Finally, it can generate IPv6 unique local prefixes.

utftpd is a TFTP server with fine-grained access control, support for blksize (RFC 2348), timeout options and support for revision control. You can assign three different kinds of rights to every client: - read: the right to read a file. - write: the right to write to an already existing file. - create: the right to create a file. Clients may be specified by a single ip address or a range of addresses or by ip address and mask. Revision control is optional and will never be turned on automatically for any file (you have to do the initial checkin into by hand).
