4 SONAR
The role of the Sonar test server in 7signal Sapphire is to emulate one of the customer’s
production servers. Sapphire Eye or Micro Eye connects to Sonar to measure QoS provided by
the network. Measurements are performed in both directions (uplink and downlink). Uplink
means traffic from end-user device (e.g. Eye) towards network (e.g. Sonar). Downlink means
traffic from network towards the end-user device.
Single Sonar can serve several monitoring stations which has access through IP networks to
Sonar. One Sonar server can therefore be used as the test point for several networks.
The 7signal Sapphire solution supports the concurrent use of several Sonar test servers, which
means that Sonar can be installed on several servers within a company. Using several Sonars
enables the company to detect and locate problems in its network. Sonar can be located in the
same network as the access points, in a server room in the same building, or anywhere on the
Internet – such as in the centralized identification and authorization center of an international
organization.
