GL launches real-time VoIP network-monitor system

'Packetscanweb, along with GL's Packetscan, Listener and Oracle database, provide the essential elements for a centralised packet-monitoring system,' said Karthik Ramalingam, project manager.

Packetscan captures live VoIP traffic and segregates into SIP, H323, Megaco or MGCP-type calls.

Hundreds to thousands of calls can be monitored in real-time, including detailed analysis of selected voice-band streams.

Packetscanweb is a network monitoring extension of Packetscan, wherein multiple Packetscans monitor and provide statistics to a central database.

With Packetscanweb, users can assess, in real-time, various network-wide statistics using a simple web-based interface.

'Using any browser-capable-device, you can access the results from anywhere in the world,' Ramalingam added.

The real-time data consisting of details of all calls captured or measured by various Packetscan probes are displayed.

Packetscanweb provides various statistics, such as probe name, calling/called number, start time, call duration, session request delay (ms), session disconnect delay (ms), originating IP address, and destination IP address.

Call detail records can be displayed based on time filter or record index and have an option to export into PDF form.

Each call detail is depicted by message sequence that gives a ladder diagram of the call flow between the called and the calling numbers.

And enhanced graphs and reports view provides an overall summary of the captured packet traffic over the entire network with the help of graphs such as call-volume display, call-failure cause, session request delay (SRD), listening and conversational MOS display.
