QoS & Traffic Management Solution

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

What is QoS and Traffic Management?

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.

How Our Traffic Management Solution Works

The Stingray Service Gateway prioritizes traffic as follows:

IP packets hitting the SSG form a flow. The DPI engine determines for each flow compliance with signatures that are loaded from the VAS Cloud and can be customized by the operator.
The network administrator distributes signatures according to traffic classes, taking into account priority: for example, the major part of the bandwidth is given to YouTube traffic ensuring high quality of video downloading and streaming, and the lesser part is given to torrents.
Network resources are distributed in such a way that the subscriber does not have problems with highly sensitive services.

Key Features of Stingray QoS for Traffic Management

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 favor 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 Q-in-Q 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.

Why Choose VAS Experts?

Deep expertise in DPI and network technologies

The company is the developer of the Deep Packet Inspection (DPI) solution with its own, constantly updated signature database. This allows for the accurate identification and classification of more than 6,000 applications and services (from streaming video to IoT protocols), which is the foundation for all solutions.

Converged all-in-one platform

Instead of a set of disparate systems from different vendors, VAS Experts offers a single software platform that combines the functions of BNG, CG-NAT, traffic prioritization and filtering, network protection

This simplifies network management, reduces infrastructure complexity and total cost of ownership (TCO).

Software-Based Approach: Flexibility and Cost Reduction

The solutions run on standard x86 hardware, allowing for lower CAPEX and OPEX due to:

replacement of vendors' proprietary hardware
easy scaling and upgrading
quick deployment of new services and functions without replacing hardware.

Experience proven by successful implementations worldwide

The company has more than 2,000 implementations in 50+ countries (Europe, CIS, Latin America, Asia, Africa). This experience confirms that the solutions work in networks of any scale and are adapted to different requirements of regulators and businesses.

Easy migration from Sandvine, Cisco and other vendors

VAS Experts has proven methods and tools for seamless transition from other vendors' platforms, which minimizes risks and eliminates downtime for the operator. This is a direct consequence of experience and compatibility of solutions.

24/7 technical support and individual approach

VAS Experts provides a full cycle of support: from implementation to round-the-clock support and regular software updates and DPI signature database.

In addition, the company's engineers are ready to adapt solutions to the specific tasks of a particular operator.
