Patent ID: 8868715

Claim:
A method comprising: analyzing network traffic statistics of a network using at least one processor; analyzing end-to-end QoS measurements of two directions of at least one call; identifying network devices and links traversed by the at least one call, wherein the identified links are communication links connecting the network devices; determining QoS metrics for at least one of the identified network devices and at least one of the identified links traversed by the at least one call; relating the network traffic statistics with the end-to-end QoS measurements on a common timescale and across network paths; displaying network topology using the at least one processor; displaying traffic measurements of the network devices and links; displaying one or more graphs of the end-to-end QoS measurements of the two directions of the at least one call and the QoS metrics for the at least one of the identified network devices and the at least one of the identified links over a measured time period; and displaying a visually distinctive area that indicates a threshold of acceptable calls.
