Optical LAN is the best choice for implementing open-source and standards-based SDN in the LAN

This is the final blog in a series that covers how the US Federal Government continues to deploy traditional copper-based LANs while investigating how to add Software Defined Networking (SDN) functionality inside buildings and across campus. Previous blogs covered why Tellabs OLAN is architecturally the ideal choice for SDN, why legacy copper-based LANs is poorly suited to accommodate SDN and how OLAN already matches SDN intent and already supports SDN like functionality today.

Now here is when this topic gets real interesting.

Ultimately the goal for a true SDN is that it is open-source and standards-based. Frankly, the legacy copper-based LAN equipment manufacturers are not, and likely will not follow through with this deliverable.

On the contrary, PON is already an integral part of the SDN evolution with NETCONF, YANG and OpenFlow models already under study by standards bodies like FSAN, ITU, BBF and ONF. Furthermore, the Virtual Optical Line Terminator Hardware Abstraction (VOLTHA) initiative is driving the SDN application for PON and many major players, like AT&T, are contributing to this initiative right now.

The best proof of this comes from AT&T’s recent SDN announcement that their VOLTHA work with the Open Networking Foundation (ONF) includes their 10G symmetrical XGS-PON equipment being supported by the first release of VOLTHA software. What that means is that the VOLTHA “brain” is providing the vendor agnostic PON management over vendor-specific 10G symmetrical XGS-PON hardware devices today.

Very impressive AT&T!
