Selective user plane monitoring multiple monitoring probes when a serving gateway has multiple IP addresses

Last updated:

Abstract:

A system for selective user plane (UP) monitoring includes a service gateway (SGW) having a plurality of units. The system further includes a network packet broker (NPB) configured to receive packets including UP data from tunnels created to enable transmission of the UP packets from UE to the plurality of SGW units. The NPB is also configured to receive packets including control plane (CP) data from channels enabling transmission of the CP packets from a base transceiver station to the SGW. The system also includes a plurality of probes operatively coupled to the NPB. The probes are configured to generate first metrics associated with the received CP packets and to selectively generate second metrics associated with the received UP packets based on one or more identifiers. The NPB is configured to forward UP packets being processed by a particular SGW unit to a particular probe of the plurality of probes.
