Real-time traffic (voice and video) demands a network that delivers low latency, low packet loss and low jitter. And that's not easy to accomplish. The dynamic character of modern networks, and the growing requirement for highly distributed configurations can lead to errors in design or implementation that cause quality problems for voice and video apps. And so, a new breed of testing methodologies and tools is required to test or monitor converged networks and to isolate problems. This presentation will analyze and categorize these tools, and list vendors that provide the different kinds of solutions needed to manage today's complex networks.
