Core network sites where GTP protocol is used are facing an extremely increase of traffic that the existing monitoring tools are unable to cover. While respecting GTP protocol correlation Aster A-818 A-820 can smartly reduce the amount of traffic, preserving users data integrity.
IMSI based stateful correlation of GTP-C and GTP-U messages,
Session based off-load of useless traffic (e.g. IMSI or APN based),
Load balancing subscribertraffic flows to the output ports.
