A number of Voice over Internet protocol (VoIP) trials are under way. The purpose of trials is to learn what is required to successfully launch and operate a new service. Those already familiar with the Packet-Cable reference architecture will recognize the central elements of the platform: access network, call management server, gateways and back office. Dealing with technology-based services, it is easy to fall prey to "feature creep," forgetting the need to weigh the capital and operating expenditures required to install and maintain the equipment. Securing the network against attack is an area of concern for engineers. Service-destroying attacks must be prevented from reaching network elements where the damage could affect customer service or potentially shut down the network. Multimedia extensions to Packet Cable enable real time services, and the question to consider is how to build the foundation for next generation services with today's investment.
