Often times when deploying network monitoring probes they are passive devices tapped into the network using port spans, also known as port mirroring. Since the Acme Packet SBC is acting as a SIP b2bua and sees all SIP traffic it also has the ability to act as a probe without the need for port spans or mirroring.
Using IPFIX (IP Flow Information Export) the SBC will provide real-time statistics to the Oracle Communications Operations Monitor (formerly Palladion) Mediation Engine. The ME is able to provide real-time SIP ladder diagrams, call correlation, detect one-way RTP audio streams, provide alerting (fraud detection, call failures, emergency 911), display SBC configs, report on degraded MOS and RFactor scores, as well as show devices performing SIP Registration through the SBC and their associated endpoint make, model, and firmware information.
Currently Operations Monitor is the only platform I am aware of that can perform all of this real-time with no delay or lag. SIP ladder diagrams will display and continue to refresh in real-time whether a call is in progress or mid-call with intermediary dialog taking place.
All traffic traversing through the SBC north and southbound is reported using IPFIX
The network-interface configuration element on the SBC determines which interface is used to send the IPFIX Export Data to the Mediation Engine. In most cases it will be the Management interface although it could be a slot0 or slot1 interface if desired.
Oracle Operations Monitor’s Mediation Engine supports an interactive multi-tenant web interface using HTML 5.
While the SBC is sending IPFIX Export Data the Operations Monitor platform will display SIP ladder diagrams on a per call basis showing a correlated call flow in real-time.
