This module investigates the QoS service details necessary to provide acceptable voice quality over the best effort data network. Here, we first discuss general converged network QoS requirements. We find that QoS parameters extend beyond just bandwidth and delay, but also include jitter, packet loss, network availability, and security. We discuss traffic shaping and admission control, and learn how we can use admission policies to direct our network devices to handle different traffic types. We learn that frame tagging techniques help us segregate and prioritize our real-time traffic and non-real-time traffic. We explore the International Telecommunications Union Telecommunications (ITU-T) Standardization Sector H.323 packet multimedia transmission standard details. We examine the various H.323 components and protocols that make complex voice and video packetization work. We then introduce many of the varied QoS techniques, such as Differentiated Services (DiffServ), IP Precedence, Random Early Discard
