Diameter Interfaces

F5 Traffix Signaling Delivery Controller (SDC) Supports 50+ Interfaces

Fully Compliant with 3GPP and More

Traffix Diameter protocol solutions support over 50 Diameter interfaces, such as: Gy interface, Gx, Sp, S6d, S9, S6a, Sy, Rx, SWx, Ro, Gz, Sta, SGi, SWm, S13 and others. We also support vendor specific variants of a given interface.

Looking for info on a specific Diameter interface? Press and hold CTRL + F then type the name of your interface.

The SDC provides a future compatible, dynamic, flexible and simple mechanism for adding new Diameter interfaces by uploading Diameter data dictionaries to the solution. The dictionary is in a XML file format. The solution supports simultaneous usage of multiple dictionaries, enabling a Diameter Signaling Delivery Controller to interconnect with multiple Diameter nodes. The SDC provides seamless and transparent support for any vendor specific AVPs. The system can transparently handle multiple different versions of the same AVP with different encoding.  If the solution needs to modify these AVPs, they can be added into the dictionary file with different names, to allow a user to access and modify these AVPs using their real names.

The complete list of interfaces supported by the SDC is available in the table below. The solution is compliant with 3GPP Releases 7,8, 9, 10 and 11.
