Element Function
TD140

At ingress ports, TD140 collects GTP traffic from S1-U, S11, S5/S8, S4, and Gn
interfaces in the packet core network.

Other traffic (non-GTPv1/v2 IP protocols) is load balanced based on IP

At egress ports, TD140 distributes packets based on session correlation among a
pool of G10s. It adds metadata including timestamp and port tag.

Generates alarms and forwards to Iris server.

Generates system health statistics for future use.
G10 Probes

Generates GTP session records and forwards to the Iris server. Session mapping
is persisted at probes:
- On failure/reboot of TD140, probes provide stored session mappings to TD140
- On failure of probe, configuration option to enable/disable rebalance of sessions
across remaining probes

Generates GTP XDRs and streams them to DataCast.

Generates alarms and forwards to Iris server.

Generates system health statistics for future use.
