The convergence of voice, data, and video networks is creating a new environment with major challenges for telecommunications. In response to the changes, telecommunications equipment manufacturers and service providers are competing fiercely to bring quality solutions to market first. From then to now In a traditional telecommunications network, communications intelligence is distributed among various devices.
Network elements provide collective call processing intelligence.
As the intelligence of the converged network shifts from the core network to the edges of the network, communi cation equipment becomes increasingly sophisticated. In the next-generation converged network, the call processing intelligence is localized in devices at the edge of the network. Bandwidth sufficient to handle bearer data is guaranteed in the circuit-switched model. In the converged network, mechanisms for transporting control signaling and bearer data compete for bandwidth, possibly affecting quality of service. A new paradigm for testing signaling and bearer data channels as well as various technologies simultaneously is required.
