Getting visibility into the 5G core network requires a fabric that can access data through various virtual tapping (vTap) solutions from network equipment manufacturers (NEM), third parties, and network function providers (NFP). The visibility fabric must be able to terminate, process, and forward 5G core data packets in different encapsulated formats from the virtual taps to the monitoring probes.
Automation helps remove the complexity of the network layer communication between the taps and the probes. It requires a visibility fabric that can capture traffic from multiple sources in a coordinated and synchronized manner. The resulting data provides insight into the 5G core in multivendor deployments, enabling duplicate packets to be recognized and processed. Also needed is the ability to replicate traffic to feed multiple probe environments and a visibility fabric that can upgrade to new probes without changing the underlying architecture or transport layer.
