QoS Traffic Policing

Quality of Service (QoS) service allows to achieve a high output by the ability of DPI technology to classify all traffic by priorities, providing wider bandwidth to certain applications and protocols.

Availability and high quality of service are the main indicators of the provider’s performance. Such problems as slow pages’ downloads and stuttering sound during video calls are very annoying for users. These issues can be improved by managing QoE (Quality of Experience) with the QoS function of the Stingray platform.

QoS helps a network device (router or similar) to optimize traffic to be sufficient for the applications which are critically important for users. The service can dynamically apply various methods of differentiation to traffic. It is mostly applicable in IP telephony, IPTV, video conferencing, and other delay-sensitive services.

Benefits of QoS

  • Load-resistant and always available network
  • Real-time mapping and automated solution of network and applications performance issues
  • Possibility to setup custom policies and quotes to block the specific content or to prevent network abuse

Provider Challenges That BNG Solves

Ensures Internet access quality and speed

Differentiates and prioritizes traffic

Prevents network overload

Features

Hierarchy of Prioritization

To ensure QoS, Stingray SG allows traffic prioritization on all stages of its delivery to the user:

  • by common channel
  • by the subscriber’s tariff
  • by VLAN and ports if there are several UPLINKS (channels to upper provider) and need for balancing

Upper Limit Control

Stingray Service Gateway allows monitoring the channel’s upper limit.

When a user approaches this limit, the service prioritizes traffic by protocols and directions: for low-priority traffic forced out of bandwidth in favour of high priority one.

Decrease Expenses

To avoid purchasing additional UPLINK speed during peak hours, the QoS function assigns lower priority to background applications (torrents, file downloads, updates, etc.) and higher priority to online video, web browsing, or online games.

So during peak hours, the user will not notice quality deterioration, and the UPLINK speed will not be exceeded.

Traffic Mapping

To ensure the required QoS on the router or shaper, Stingray SG changes the priority field of the packets passing through it after defining a protocol or an autonomous system.

The following fields are supported:

  • DSCP/TOS in the headline of IP packets
  • priority in VLAN and QinQ packets’ headlines
  • traffic class in the headline of MPLS packets

Users' Tariff Plans

Stingray SG allows to limit the bandwidth for the user (within the tariff plan) and to prioritize traffic within this bandwidth. It provides high Quality of Service for the most demanded applications - even if the same IP address is assigned to several users, one of which loads the channel unevenly (for example, by running a torrent client).

Assigning high priority to sensitive services like streaming video, IP telephony, IPTV ensures their stable operation and high quality.
