SigScale OCS

SigScale OCS performs the AAA (Authentication, Authorization & Accounting) functions for Network Access Servers (NAS) (e.g. Wi-Fi access points). To perform these AAA functions, OCS uses RADIUS (Remote Authentication Dial-In User Service) protocol. It also manages subscriber account balances, debiting in real time, to support a prepaid service. SigScale OCS will be released as a fully open source project hosted on GitHub with binary installable packages available for several popular Linux distributions.

  • Highly Available

    Application architecture will support and re-enforce the protection in other layers to ensure the maximum availability.

  • Low footprint

    Underlying Erlang OTP stack ensures the OCS utilizes the lowest amount of CPU cycles hence providing a smooth performance with minimum resources.

  • Massively scalable

    Modularized architecture allows the expansion with ease.

  • Simple installation and management

    We provide binary packaged distributions for popular environments.

  • Embedded internal RADIUS servers

    WISPs don't have to worry about integrating an external RADIUS Server and databases since the SigScale OCS has an embedded internal RADIUS server.

  • Concurrency Oriented

    OCS is all about handling lots of traffic and many of them at the same time

OCS Management

  • A modern material design interface provides an intuitive front end to the powerful backend engine of SigScale OCS. The UI is easy to use for all day to day operations, making management a pleasure. Securely access it from anywhere with desktops, tablets and smartphones.


    The UI also provides reports on both accounting and access requests. Operators may check current activity or browse archived IP detail records (IPDR).

  • Clients

    Quickly and easily add a network access server (NAS) to the Clients table by identifying the IP address and password (secret) assigned to the device. Only known clients will be authenticated, others are ignored. Disconnect and change of authorization (CoA) port may be tailored for each client device.

  • Subscribers

    End user device credentials are added to the Subscribers.table. Several types of authentication may be used including MAC, simple username/password and extensible authentication protocol (EAP). An Ethernet address as identity, with no secret (password), may be used to replace static access control lists (ACL) or Mikrotik WPA-PSK may be used with unique pre-shared keys per MAC. Usernames may be authenticated using passwords. Where devices support EAP a compatible method will be negotiated with configurable preference of either EAP-PWD or EAP-TTLS.

  • Credit Management

    Each subscriber is given a starting balance when they are provisioned. Real time accounting manages that balance and when it is depleted the subscriber will be disconnected immediately. The balance may represent a safety limit for "unlimited" packages or may be fine grain managed with topups done over the REST API interface.

Cellular Experience ! Without Captive Portals

Why can't connecting to a Wi-Fi network be as easy as connecting to a cellular network ?
