QoS and Traffic Performance Analysis using the HP E5200A Broadband Service Analyzer

Quality of Service (QoS) is the term used to describe the end-to-end network performance of an ATM connection. At the ATM layer, a set of QoS parameters and traffic types are defined that allow QoS to be managed on a network.

These parameters and classes form the basis of the connection agreements between a service user and the network operator. In a connection agreement, the network guarantees to meet or exceed the QoS requirements of user connections that conform to agreed traffic characteristics.

The QoS parameters defined by ATM Forum TM4.0 and ITU-T I.356 include
- cell error ratio (CER)
- cell loss ratio (CLR)
- cell misinsertion rate (CMR)
- cell transfer delay (CTD)
- cell delay variation (CDV)
- severely-errored cell block ratio

The HP E5200A Broadband Service Analyzer offers a range of SMARTtests and several predefined macro tests that allow you to quickly and easily determine whether your network is meeting the agreed QoS parameters and network performance.
