Ken Salchow, F5 Network's manager of Core Technical Marketing, explores the IP Multimedia Subsystem, or IMS. Salchow explains that IMS is set to become the framework that Internet Service Providers will use to deliver new, highly customizable services, by separating the access network from the service network. IMS will benefit ISP's by allowing them to offer a greater variety of products, with more network efficiency, and IMS will benefit consumers, providing new choices in products, services and mobility. Salchow suggests that IMS brings the concept of Fixed Mobile Convergence one step closer to reality.
