QoS manager software is used for entering QoS probe settings, calculating latency and jitter packet loss, and analyzing bandwidth. All parameter data are saved as .csv files at specified times, and the SNMP function allows for the transfer of data to the upper network management software.

Up to 10 probes per package
|
|
|
QoS manager software can handle up to ten QoS probes. Using the Probe Registration function, each of the probes' IP addresses can be registered. In addition, each probe can be synchronized with an NTP server, GPS, or external lpps clock.

Using the filter function
to select various packets
|
|
|
The data filter function takes packets that have passed through the packet filter and indicates the places that were matched in the Manager software.

Packet filtere and data filter
|
|
|
Manager software has two measurement modes: Continuous measurement mode and window mode.
|
- Continuous measurement mode
In Continuous measurement mode, the packets passing through the QoS probe are continually monitored. Since all packets are subject to filtering, this mode provides an effective means for solving network problems.
Note
There is a limit on the number of packets that manager software can handle continuously. In the case of 100BASE-TX, manager software might not be able to handle all packets depending on the filter conditions.

|
|
|
- Window mode 1
This mode reduces data processing performed by mManager software, so making it effective even if you connect several probes, or when network traffic is high.
- Window Mode 2
In window mode 2, the measurement interval can be divided into some preset number (cycle) and the packets in the specified period of time are measured at each cycle. Various kinds of packet measurement can be realized by setting different filtering conditions for each cycle. The figure above shows a case in which the interval is divided into four cycles. Since two filtering conditions can be set per cycle, a maximum of eight conditions can be set in this case.

Using the SNMP MIB function, the QoS monitoring system can be combined with the upper network manager software. The report function of manager software produces graphical reports on latency, jitter, or packet loss.
