We've been using, for example, the CA service assurance solution for physical network infrastructures, and we've been using that. Now as the network infrastructure evolves more towards a virtualized network function that really brings in the need for the VNA, so that now you can take the service assurance stack and make it work both with the physical as well as the virtual networking infrastructure. I think of the other broader things as the industry is migrating from physical infrastructures to virtual infrastructure, I think there's a bigger question that the industry is looking, is how to we close-loop the fulfillment and assurance. I think as we look at closing the loop between the fulfillment, so that we can really start bringing in close-loop control and really start achieving higher levels of automation all in the network. I think that's the next big step, and obviously in that regard I'm sure the solution will evolve further and bring in those capabilities that can make those close-loop controls realized in the real world.
