You can create a GPRS Tunneling Protocol (GTP) profile type on the BIG-IP® system to manage Global System for Mobile Communication (GSM), Universal Mobile Telecommunications System (UMTS), and latterly Long-Term Evolution (LTE) subscriber traffic across User Datagram Protocol (UDP) connections. The BIG-IP system supports GTP versions 1 and 2 on UDP connections. When configuring the GTP profile, you can specify the maximum number of messages held in the GTP ingress queue.
The BIG-IP® system enables you to manage GTP traffic by configuring the GTP profile for use with a pool and virtual server. When using the GTP profile, you can specify the maximum number of messages held in the GTP ingress queue.
