Not familiar with the terms "session border controller" or "session delivery network"? Don't worry. Andy Ory, CEO of fast-growing Bedford, Mass.-based Acme Packet, is more than happy to share his passionate vision of how SBCs and SDNs -- and the emerging era of "opt-in communications" -- will change your business and the world. In this installment of the IDG Enterprise CEO Interview Series, Ory spoke with IDGE Chief Content Officer John Gallant about how Acme Packet is bringing identity, security and control to the wilds of the Internet, and why the world's top carriers -- and a growing number of enterprise IT shops -- are relying on the company to reduce costs and develop a whole new generation of network services.
