For mobile carriers, network service dependability and customer experience are critical to success. But while network probes can provide visibility into wireless core networks, these devices have limited capacity and may not withstand fluctuating mobile subscriber traffic. At the same time, underloading network probes can create additional costs. Only by striking the right balance can carriers improve visibility into wireless networks while controlling costs.
The Ixia GTP Session Controller 7433 helps service providers maximize network probes and capacity while improving visibility into wireless core networks. The solution effectively identifies and tracks mobile subscribers and load balances that the network probes by enforcing capacity and rate limits for each customer, even as mobile traffic rates fluctuate. If the controller detects faulty or overloaded monitoring probes, it automatically redistributes the load to other probes in the cluster. As a result, monitoring probes are able to focus on Quality of Experience (QoE) analysis rather than spend cycles trying to reassemble GTP session traffic.
