Securing GTP and SCTP Traffic

Support for rate limiting based on APN-controlled aggregate rate limiting (SRX1500, SRX4100, SRX4200, SRX4600, SRX5400, SRX5600, SRX5800, and vSRX)–Starting in Junos OS Release 21.2R1, you can apply rate limiting for specific access point names (APNs) by using APN-controlled aggregate rate limiting (ARL). You can also configure APN groups and attach these groups to the GPRS tunneling protocol (GTP) profile for ARL. Configure the apn-control statement at the [edit security gtp] hierarchy level to enable the various configurations of APN-controlled ARL.
