Per user QoS

In our previous section, we explained per host rate limiting (see details). Per host bandwidth control is purely based on IP address, on a per IP/host basic. It has no visibility on the user identity and it’s not possible differentiate different service levels for different users within the same network.

Per user bandwidth control/allocation provides the granularity to assign bandwidth based on user’s identity. We can configure different user profiles, and attach the desirable profile to specific users to map to our access policies, eg. user1 logs and assigned with 2Mbps upload/download, user2 logs in and assigned with 4Mbps upload/download. This feature is only applicable on HotSpot Gateway or HotSpot Access, and is part of our HSG user authorization (access control) feature.

NOTES:

    • user accounts must be locally created within HSG RADIUS (or cloud RADIUS for HSA)
    • user authorization profiles (access policies) must be created within RADIUS. Each access profile sets the min/max bandwidth per user.
    • each user must be attached with their respective access profile.
    • different user can have different access profile, therefore having different access privileges even within the same network

Configuration prerequisites:

    • HotSpot service must be enabled on the user LAN, configured through CLI
    • Configure user accounts, profiles and assignments from RADIUS portal

CONFIGURATION EXAMPLE

In this example, we are trying to achieve following objectives:

    • subscribed backhaul bandwidth is 100Mbps
    • network (LAN-eth1) is allocated total 50Mbps, per host is capped at 2Mbps upload/download
    • network (LAN-eth2) is allocated total 50Mbps (with captive portal enabled)
      • some users (user1) are capped at 4Mbps upload/download, no guaranteed bandwidth
      • some users (user2) are capped at 8Mbps upload/download, no guaranteed bandwidth
      • some users (user3) are capped at 8Mbps upload/download, but guaranteed with 4Mbps upload/download.

RADIUS setting (for user accounts and access profiles)

RADIUS setting are done through a GUI - RADIUS portal.
