Systems and methods for monitoring traffic across Diameter Core Agents (DCAs) 501 such as, for example, Diameter Signaling Routers (DSRs) and/or Diameter Routing Agents (DRAs). In some embodiments, a method includes receiving a first set of one or more messages 506, 509 at a telecommunications monitoring system, the first set of one or more messages transmitted between a Diameter client 502 and a Diameter device 501. The method also includes receiving a second set of one or more messages 507, 508 at the telecommunications monitoring system, the second set of one or more messages transmitted between the Diameter device 501 and a Diameter server 503. The method further includes correlating the first set of one or more messages with the second set of one or more messages as part of a single Diameter call, i.e. it is determined that those messages correspond to a single call. This process may allow downstream applications to construct an end-to-end view of the Diameter call, and provide key performance indicators (KPI)between LTE endpoints. Since diameter core 501 only modifies a few specific Attribute-Value Pairs (AVPs) of the ingress packet's 504 header, only the modified AVPs may be extracted without performing full decoding transaction and session tracking of egress packets 505 (Intelligent Delta Monitoring). |
