eGTP-C Support for Enhanced S-GW Restoration
This fuctionality is now supported. See
GTP Throttling
Corrected Content: This section includes corrections to previously published content. The previous content stated that,
“This feature has been implemented as lab quality. All associated CLI commands and performance statistics are also
now supported at lab quality”, which is incorrect. GTP Throttling functionality has been implemented as deploy quality.

This feature will help control the rate of incoming/outgoing messages on P-GW/GGSN. This will help in ensuring P-
GW/GGSN doesn’t get overwhelmed by the GTP control plan messages. In addition, it will help in ensuring the P-
GW/GGSN will not overwhelm the peer GTP-C peer with GTP Control plane messages.

Important:
Use of GTP and Diameter Interface Throttling requires that a valid license key be installed. Contact
your Cisco account representative for information on how to obtain a license.
This feature requires shaping/policing of GTP (v1 and v2) control messages over Gn/Gp and S5/S8 interfaces. Feature
will cover overload protection of P-GW/GGSN nodes and other external nodes with which it communicates.

Important:
GTP throttling will be done only for session level control messages. Path management messages will
not be rate limited.
External node overload can happen in a scenario where P-GW/GGSN generates signaling requests at a higher rate than
other nodes can handle. Also, if the incoming rate is high at P-GW/GGSN node, we might flood any of the external
nodes; hence, throttling of both incoming and outgoing control messages is required.
