OpenFlow - Enabling Innovation in Networking and Routing Protocols.

RouteFlow, is an open source project following the centralizing network control, unifying state information and decoupling forwarding and configuration from programmable networking hardware. RouteFlow is composed by an OpenFlow controller application and a RouteFlow server running a virtual network environment that reproduces the connectivity of a physical infrastructure. This virtual network also includes routing engines that generate the forwarding information base (FIB). In turn, the FIB is translated into OpenFlow tuples taht are installed in the OpenFlow-enabled devices of the forwarding plane. RouteFlow is the evolution of our early work on QuagFlow -- Partnering Quagga with OpenFlow and works transparent to the specific routing engine (e.g., Quagga, XORP, BIRD) as long as it is based on the Linux networking stack.

OpenSS7 is an opensource development project to provide a robust and GPL'ed SS7 stack for Linux and other UN*X operating systems

The content-addressable network (CAN) is a distributed, decentralized P2P infrastructure that provides hash table functionality on an Internet-like scale. CAN was one of the original four distributed hash table proposals, introduced concurrently with Chord, Pastry, and Tapestry.

Kademlia is a distributed hash table for decentralized peer-to-peer computer networks designed by Petar Maymounkov and David Mazières in 2002.[1][2] It specifies the structure of the network and the exchange of information through node lookups. Kademlia nodes communicate among themselves using UDP. A virtual or overlay network is formed by the participant nodes. Each node is identified by a number or node ID. The node ID serves not only as identification, but the Kademlia algorithm uses the node ID to locate values (usually file hashes or keywords).

Stochastic diffusion search (SDS) was first described in 1989 as a population-based, pattern-matching algorithm.[1] It belongs to a family of swarm intelligence and naturally inspired search and optimisation algorithms which includes ant colony optimization, particle swarm optimization and genetic algorithms; as such SDS was the first Swarm Intelligence metaheuristic. Unlike stigmergetic communication employed in ant colony optimization, which is based on modification of the physical properties of a simulated environment, SDS uses a form of direct (one-to-one) communication between the agents similar to the tandem calling mechanism employed by one species of ants, Leptothorax acervorum.

Time is eternal, but methods of tracking it are not -- and so a Johns Hopkins University astronomer wants to replace the Gregorian calendar, with its leap years and floating dates and 15th-century effluvia, with a sleek and standardized system for the world.

One of the most-hyped features of the erstwhile BeOS was its fully buzzword-compliant filesystem. BFS had it all—journaling, 64-bit support, a database-like metadata, streaming access support, and multithreaded reads. But there were some warts there, too. Ars takes a look back at BFS, and talks to one of the Be employees who build the filesystem. We also talk to the coder behind the open source version of BFS.
