US Patent:

8472384, Jun 25, 2013

Filed:

Nov 30, 2010

Appl. No.:

12/956800

Inventors:

Jesse C. Shu - Palo Alto CA, US
Chaohui Zhang - Foster City CA, US

Assignee:

Juniper Networks, Inc. - Sunnyvale CA

International Classification:

H04W 4/00

US Classification:

370328

Abstract:

GPRS Tunneling Protocol (“GTP”) packets are intercepted by receiving a GTP tunnel packet, determining whether the GTP tunnel packet is to be intercepted, intercepting GTP tunnel packets if it is determined that the GTP tunnel packet is to be intercepted, and processing the intercepted GTP tunnel packets. Multiple tunnels may be intercepted simultaneously and GTP tunnel packets from different tunnels may be processed differently. Implementations include both inline and offline interception of GTP traffic between SGSN and GGSN.
