Abstract: A cluster load balancer can be coupled to a network for monitoring network traffic. The cluster load balancer can include one or more computing devices. The one or more computing devices can be configured to receive a data packet, the data packet comprising a device identifier of a first device connected to a network for a communication session, wherein the data packet is a user plane data packet or a control plane data packet; generate a probe identification based on the device identifier of the first device in the data packet; add the probe identification to the data packet; and transmit the data packet with the probe identification to a second device in communication with a plurality of network probes. The second device can be configured to forward the data packet to a network probe of the plurality of network probes based on the probe identification in the data packet.
