Quality of Service (QoS) is becoming increasingly important for many organizations. Applications such as Voice over IP (VoIP), video, and business systems compete with other less critical traffic for limited network resources, especially at the Wide Area Network (WAN) access point. Limited resources can create data loss or delays in the flow of information. This is particularly true with VoIP - delayed voice or dropped calls are just a few examples.

Companies need to protect their investment in the WAN, ensuring it is used for key business applications. IP convergence is also creating new challenges. Convergence often brings cost savings but can also add complexity. Finally, many new services and IT applications are entering the market. What should you look for in QoS products? Low cost, fast and easy installation, and a standards-based solution are required.
