Freehold Township, NJ – October 26, 2011 – Traffix Systems, the Diameter control plane experts, contributed Diameter routing support with its DRA in the VoLTE (Voice over LTE) Interoperability Testing event that was organized by the MultiService Forum (MSF) and backed by the GSMA, the association representing the interests of mobile operators worldwide. The test event held in September 2011, backed by the GSMA as part of its VoLTE initiative, focused on validating key network interfaces to ensure multi-vendor deployment strategies for LTE/EPC/IMS technology and setting best practices for LTE deployment strategies.

The Traffix expert team demonstrated core Diameter routing, bridging of Diameter interoperability gaps between vendors, LTE roaming, security and other interconnect use cases, utilizing dynamic policy control between home and visited networks employing DRAs (Diameter Routing Agents).

“Traffix participation with its Diameter platform Signaling Delivery Controller (SDC) succeeded in showing the central role of DRAs in LTE networks,” said Lenny Ridel, CTO of Traffix. “We validated roaming scenarios as specified by GSMA PRD IR.88 (LTE Roaming Guidelines for VoLTE S6a and S9 interfaces), and the MSF inclusion of DRA technology within a single PLMN. The SDC also provided protocol normalization for Diameter messages to support interoperability.”

“We’re pleased to welcome Traffix to the MultiService Forum,” stated Kyu-Ouk Lee, MSF President. “The knowledge, experience, and enthusiasm that Traffix brings to the MSF will make a valuable contribution to our ongoing interoperability program, and we welcome its contribution.”

The market leading Traffix Signaling Delivery Controller (SDC) consolidates Diameter Gateway, Diameter Load Balancer, and Diameter Router solutions on one unified platform. Traffix will continue to participate in building and validating practical LTE network use cases in industry forums for deployment scenarios with the SDC.
