Well, I think it’s – I mean, there are – I mean, when you go to software, I think, you have to do a N number of things to make it transmit into people. For example, people, did they still want finished products, so we have to increasingly use the channel and all those. So, there are few things we are working on to really get ready for that model because just getting a one-stop shopping was more convenient for the customer, but lower margin for us and higher price for them and so, everyone is attractive towards that, but I think it’s going to take some time every customer is making a decision on their own timetable and depending on – it also depends on what’s the traffic rates are. If the traffic rates are very high, then going to a software solution is lower price and they will probably want to go on to – will probably want to go to the software model. But when the traffic rates are lower, like tier-2 provider, it’s not big advantageous because there is a minimum threshold of price that you have to cross to take advantage of software. So, all these make a difference, also the software product has basically two versions. One is basically buying software for traditional datacenter and that’s what we are talking about. Moving forward, as we have go to the cloud, the software is the only judge. So, when we say we are releasing multiple versions, there are about 10 to 20 different models, deployment models ranging from software in the cloud to software in the datacenter to buying a full function appliance to buying the tech product the way it was. So, it’s a many choices and we work with them to come out with the right thing for different customers. But it’s not clear right now and at this point, we are not pushing customers one way or other and that’s going to have a impact on the margins, but, we are actually quite conservative when we talk about the gross margins. We are assuming that it is going to take some time to move toward the software model.
