Providing the required quality of service (QoS) to applications on a wide-area access network consistently and reliably is increasingly becoming a challenge. Cisco Bandwidth Quality Manager (BQM) is a network application congestion management tool that provides outstanding visibility and analysis of traffic, bandwidth, and QoS on IP access networks.Cisco BQM is part of the Cisco Network Application Performance Analysis Solution. This solution is a set of tools and services that help customers quickly isolate application performance problems and optimize their networks for current and future applications to help ensure that they meet their information technology performance and cost objectives. The solution helps maximize the value of applications and network assets by validating the behavior and performance of an application before it is deployed over the network. As part of the Cisco Network Application Performance Analysis Solution, Cisco BQM provides baseline analysis of detailed WAN traffic to help customers with problems take corrective action and avoid future problems.
