Choosing the wrong FreeRADIUS replacement platform costs carrier networks months of re-engineering and in the worst case- a full re-procurement cycle. Network architects planning this migration face constraints that generic AAA vendor content never addresses: active session continuity across cutover, BRAS/BNG compatibility with RADIUS CoA (RFC 5176), EAP method coverage for mixed-access environments, and the […]
Every time a subscriber tries to connect to your network, AAA server 5G infrastructure is the system that decides whether they get on and what they are permitted to do once they are. Get that decision wrong, or take too long making it, and the consequences cascade: failed sessions, revenue leakage, and subscribers hitting error […]
802.1X is the IEEE standard for port-based network access control. It decides whether a device may join a network before the device can send any traffic. A port configured for 802.1X stays closed until the connecting device proves its identity. If authentication fails, the port stays blocked. The same handshake runs everywhere: a switch port […]
Carrier-grade AAA (Authentication, Authorization, and Accounting) can run on Kubernetes in both public cloud and on-premises environments, and Alepo has a production deployment at Tier-1 scale doing exactly this. The architecture requires stateful session management that goes well beyond standard Kubernetes patterns, comprehensive Diameter and RADIUS protocol support, and uptime disciplines that demand careful pod […]
If you’re an ISP network engineer questioning whether your current RADIUS setup, FreeRADIUS, Cisco CPAR, or another commercial system, is adequate for where your network is going, this self-assessment gives you a structured, vendor-neutral answer. Score 7 diagnostic signs using Yes (2 pts), Maybe (1 pt), No (0 pts), then total your score. If you […]
When you compare the best AAA platforms for ISPs — or are scoping a RADIUS server replacement — the spec sheet is the least reliable thing in the room. Stated capacity, protocol checkboxes, and licence price tell you almost nothing about whether a system survives a Friday-night authentication storm or a botched migration. The eight […]
Running Cisco CPAR after end of life means operating an authentication layer that will never receive another security patch. Cisco officially ended support in October 2025. Every CVE disclosed since that date against CPAR’s code path is permanently unresolved. The exposure is not a future risk, it is a present one that compounds every month […]
RADIUS, Diameter, and TACACS+ are the three core AAA (Authentication, Authorization, and Accounting) protocols in operator networks, but they solve different problems. RADIUS authenticates subscribers at the access layer (broadband, WiFi, VPN). Diameter is the 3GPP signaling protocol of the 4G mobile core (HSS, PCRF, OCS interfaces). TACACS+ authenticates the engineers administering network devices, with per-command authorization and audit. Modern Communications Service Provider […]
The 30-day MVNO launch is real — but only if your MNO agreement, SIM vendor, and product catalog are locked before Day 1. Here’s the week-by-week breakdown of what actually happens, what causes delays, and how to avoid them.
An Online Charging System (OCS) is the real-time billing engine inside a telecom network. It authorizes a service, deducts balance or quota as the service is used, and updates the subscriber’s account instantly — before the next session starts. It is what makes prepaid, postpaid, and 5G services chargeable in real time, and it is […]
