I was recently asked for a few bullet points on some recent “interesting network infrastructure developments”. In the five minutes I had, I offered the following:
- TRILL – Transparent Interconnection of Lots of Links – a new layer 2 routing protocol which promises to replace STP. What’s really interesting about TRILL is that it does not need to be loop free; there are no blocking ports; and frames can take the shortest path. See http://www.ipjforum.org/?p=582Â andÂ http://en.wikipedia.org/wiki/TRILL_(computing).
- Open Networking Foundation – https://www.opennetworking.org/ – “The Open Networking Foundation (ONF) is a non-profit consortium dedicated to the transformation of networking through the development and standardization of a unique architecture called Software-Defined Networking (SDN), which brings direct software programmability to networks worldwide. The mission of the Foundation is to commercialize and promote SDN and the underlying technologies as a disruptive approach to networking that will change how virtually every company with a network operates.” – members include Facebook, Google and Microsoft.
- OpenFlow – http://www.openflow.org/ – “OpenFlow enables networks to evolve, by giving a remote controller the power to modify the behavior of network devices, through a well-defined “forwarding instruction set”. The growing OpenFlow ecosystem now includes routers, switches, virtual switches, and access points from a range of vendors.” – adopted by Googleand others.
- OpenCompute – slightly off networking but relevant – http://opencompute.org/ – “A small team of Facebook engineers spent the past two years tackling a big challenge: how to scale our computing infrastructure in the most efficient and economical way possible. … Everyone has full access to these specifications. We want you to tell us where we didnâ€™t get it right and suggest how we could improve. And opening the technology means the community will make advances that we wouldnâ€™t have discovered if we had kept it secret.”
