CSCum39930 - Pilot Packet to Multiple Destinations
Applicable Products: GGSN, HA, PDSN, P-GW
Feature Changes
Pilot Packet to Multiple Destinations
Pilot Packet is a feature which provides subscriber session information to an external element. When there is a trigger
for any event in which a subscriber's IP address assignment is allocated, changed, or de-allocated, a “Pilot” packet is
generated. Pilot packets are generated when:
for any event in which a subscriber's IP address assignment is allocated, changed, or de-allocated, a “Pilot” packet is
generated. Pilot packets are generated when:
Non-NAT IPv4 address is allocated to a session
Non-NAT IPv4 address is de-allocated
NAT chunk is allocated to a session
NAT chunk is de-allocated
IPv6 address is allocated to a session
IPv6 address is de-allocated
This feature is enhanced to allow Gateways to send the same Pilot Packet to up to four IP destinations/nodes. These IP
destinations are IPv4 nodes. IPv6 is not required or supported. Pilot packets have to be configured in the destination
context of a session.
destinations are IPv4 nodes. IPv6 is not required or supported. Pilot packets have to be configured in the destination
context of a session.
Previous Behavior: Currently the ASR5x00 sends Pilot Packet to only a single IP destination.
New Behavior: The Pilot Packet feature will send Pilot packets to multiple applications, up to four destinations.
