Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license. It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols (e.g. NetFlow, sFlow, IPFIX, RSPAN, CLI, LACP, 802.1ag). In addition, it is designed to support distribution across multiple physical servers similar to VMware's vNetwork distributed vswitch or Cisco's Nexus 1000V.
RANCID monitors a router's (or more generally a device's) configuration, including software and hardware (cards, serial numbers, etc) and uses CVS (Concurrent Version System) or Subversion to maintain history of changes.
RANCID does this by the very simple process summarized as:
- login to each device in the router table (router.db),
- run various commands to get the information that will be saved,
- cook the output; re-format, remove oscillating or incrementing data,
- email any differences (sample) from the previous collection to a mail list,
- and finally commit those changes to the revision control system
MidoNet is an Apache licensed production grade network virtualization software for Infrastructure-as-a-Service (IaaS) clouds.
In the field of telecommunications, a Clos network is a kind of multistage circuit switching network, first formalized by Charles Clos in 1952,[1] which represents a theoretical idealization of practical multi-stage telephone switching systems. Clos networks are required when the physical circuit switching needs to exceed the capacity of the largest feasible single crossbar switch.
Scapy is a powerful interactive packet manipulation program. It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, match requests and replies, and much more. It can easily handle most classical tasks like scanning, tracerouting, probing, unit tests, attacks or network discovery (it can replace hping, 85% of nmap, arpspoof, arp-sk, arping, tcpdump, tethereal, p0f, etc.). It also performs very well at a lot of other specific tasks that most other tools can't handle, like sending invalid frames, injecting your own 802.11 frames, combining technics (VLAN hopping+ARP cache poisoning, VOIP decoding on WEP encrypted channel, ...), etc. See interactive tutorial and the quick demo: an interactive session (some examples may be outdated).
Ostinato is an open-source, cross-platform network packet crafter/traffic generator and analyzer with a friendly GUI. Craft and send packets of several streams with different protocols at different rates. For the full feature list see below.
Ostinato aims to be "Wireshark in Reverse" and become complementary to Wireshark.
No netsplits on server unavailability
Traditional IRC networks split whenever a server has brief network connectivity issues to the rest of the IRC network, or whenever a server needs to be upgraded. With RobustIRC, your users will not notice when you roll out a new version or reboot the machine on which a particular RobustIRC server is running.
Robust against connectivity issues between clients and the network
A brief hickup of your internet connection means your session will be terminated in traditional IRC. With RobustIRC, you will transparently be connected to a different server.
The Kontalk Network is a community-driven instant messaging network designed for smartphones and tablets.
