“Thanks to Logate’s industry knowledge and expertise, we were able to successfully
integrate the AAA solution in our multi-vendor environment.
During the project their
team showed remarkable skills in creating and deploying a stable solution in 3 data
centers, all working in active-active load sharing mode.
The solution is currently serving thousands of transaction per second, while its capacity can be easily scaled at any time, which was one of our requirements that Logate has fulfilled.”

Supporting multiple access technologies on a single AAA platform
In 2018. Hrvatski Telekom sought for a vendor to replace their old AAA (RADIUS) system for fixed users and to build a test AAA system, and to extend their NFVI infrastructure. Based on the extensive experience, Logate was chosen as a provider. After successful completion of the project, the cooperation continued on the project of extending the AAA platform to support mobile users and VoWiFi. Logate managed to introduce an efficient, scalable and stable virtual AAA system that was capable to support services offered by the client in a virtual environment and across several data centers.
The capabilities of OpenProvider AAA were especially distinguishable when the system was required to handle a growing number of users and user transactions that Hrvatski Telekom ex- perienced, especially in the domain of mobile services, for which Hrvatski Telekom is known to be a leader in the Croatian market.
The system was implemented on 3 data centers, all working in the active-active load sharing mode.

The collaboration history and challenge - Crnogorski Telekom and Logate
Crnogorski Telekom is the company where Logate initially developed its OpenProvider AAA platform, in 1998, in C language, to serve the needs of the dial-up and ADSL services at that
time. As the services evolved so has the platform. In 2009. its internal architecture was completely changed with the introduction of Service Management Engine (SME) and Open Function, which simplified product configuration and runtime modification. In 2009. OpenProvider was already protocol and vendor agnostic. From the start, the platform was also designed to run in a virtual environment.
In 2012. the system was further upgraded by replacing the underlying RADIUS server with
FreeRADIUS server for protocol related functions and OpenProvider Policing engine for implementing business and policy rules, subscriber and session management. In this version
OpenProvider includes EAP with all subtypes integrated. This version also included Transparent Auto Login (TAL) functionality and extended RADIUS Proxy policing with Forwarding Authorization, Accounting, CoA and PoD packets.
Finally, the product was upgraded once more as vAAA version (VNF) that was developed in
accordance with ISG NFV ETSI standards and 3GPP standards. Designed to be deployed on
Telco Cloud environment (virtualized infrastructure) where TOSCA MANO orchestrator is
present. It was released in 2017 and maintained and upgraded since.

Since the early days of Crnogorski Telekom in Montenegro, Logate developed OpenProvider AAA from scratch to meet the developing needs of the Montenegrin telecommunications market.

- IP Policy, charging control and subscriber data management for Broadband, Mobile and WiFi users.
