Abstract
The techniques described herein present opportunities for service providers and/or network providers to optimize the Quality of User Experience (QoE) for data services by determining, using a broader network-based approach, the root cause of problems causing a service degradation. To determine the root cause of the problems, the techniques may collect different trace files from multiple different nodes in the telecommunications network. Each trace file includes a log of trace identifiers for numerous different data packets that have been generated, received, transmitted, relayed, and/or routed via the node in the telecommunications network, and each trace file log entry may be associated with a timestamp. Once collected, the techniques may correlate the different trace files from the multiple different nodes to identify, using a broader network-based analysis, service optimization opportunities.
