Built-in QoS, GoS and Security Features

The StreamStar4 Broadband Wireless Access system supports built-in Quality of Service and Grade of Service.

QoS/GoS offers:

  • Uplink and Downlink CIR and MIR (Commited and Maximum Bandwidth)
  • User Class (Priority)
  • Application and Traffic type priorities based on ToS


QoS: Quality of Service 

The native QoS defines how various types of traffic are to be handled over the network. There are three main queues at the Layer 2 scheduler level: Voice, High Priority Data, and Low Priority Data.

Voice always has the highest priority and will always be sent first.  Data priorities are determined by reading the ToS (Type of Service) byte in each IP packet. ToS values can be configured on a base station level to be treated as high or low priority.


GoS: Grade of Service

GoS is the integrated bandwidth management capability, where each terminal can be configured with a specific service class. Service classes contain the minimum and maximum uplink and downlink rates (CIR/MIR), and the user class setting. Users in the higher user class take precedence over lower class users. GoS is a terminal level setting.


Additional features include VLAN segmentation, PPPoE and DHCP packet tagging, multi-factor terminal authentication, and CPE subsidy lock.

Base Stations and Voice Controller support built-in billing features - DHCP Option 82 tagging, CDR export and real-time billing, and DNS captive portal redirection.
