Version 3.0 available!
Spines is a generic messaging infrastructure that provides transparent unicast, multicast and anycast communication over dynamic, multi-hop networking environments without the need for expensive router programming environments or low level router coding. It provides automatic reconfiguration and network flexibility required for research and production deployments.
Some of the main usages of Spines are:
- Creates generic network topologies with dynamic link characteristics (bandwidth, latency, loss rate, burstiness) on regular computer clusters.
- Deploys overlay networks in the Internet, to achieve additional services not available in the current networking infrastructure (e.g. overyay multicast), as well as improved performance for existing services.
- Creates a logical LAN over unorganized, multi-hop hybrid and wireless networks. As an example, it provides the communication infrastructure between wireless access points in SMesh, a completely transparent wireless mesh network with instantaneous handoff.
Spines instantiates virtual router nodes on participating computers and creates virtual links between these nodes. Spines uses best-effort links, as well as reliable and soft real-time links between the nodes for store and forward capabilities. Packets are routed automatically in through the network topology. The Spines topology can be dynamically adjusted, and nodes select their routing based on various metrics including hop distance, latency or packet loss.
In order to use Spines, applications use an API almost identical to the Unix Socket interface. Virtually any socket-based application can be easily adapted to work with Spines. The Spines API provides TCP and UDP-like functions for both reliable, and best effort point to point communication, and also provides multicast functinality in a transparent way, very similar to IP Multicast.
Spines was created by Yair Amir and Claudiu Danilov, and is currently developed at the Distributed Systems and Networks Lab at Johns Hopkins University.
