Modern converged networks include different traffic types, each with unique requirements for security, Quality of Service (QoS), transmission capacity, and delay. Some examples include:
Voice signaling and bearer
Core application traffic, such as Enterprise Resource Planning (ERP) or Customer Relationship Management (CRM)
“Other” traffic, such as web pages, e-mail, and file transfer

Although QoS is wonderful, it is not the only way to address bandwidth shortage. Cisco ...
