1．self-innovated

QQSG is QQ Tech’s self-innovated traffic management device working on application layer. Sitting on carriers’ MAN exit, the enabler enforces management efforts over network traffic on one POS link with 2.5G or four GE links.

2． High Performance

Based on NPU, QQSG can Create as much as 700,000 sessions per second. QQSG applies strong policy control while still maintains line rate forwarding with low delay, low jitter and low packet loss rate.

3． Powerful Application Identification

Based on DPI and DFI, QQSG-IAM can identify more than 1000 applications ，covering all kinds of mainstream application types, which include P2P, VoIP, IM, Video, Stream Media, online games, stock software, enterprise  internal applications, network management protocol, secure protocols, etc. The application identify rate is higher than 90%, which is in the leading position in the industry.

4． Flexible traffic control and Application Layer optimizing policies

QQSG supports various control manage policy; it can permit, deny or pipe traffic flow of all kinds combination of any subscribers/subscriber groups, applications/application groups, and time range. The traffic control granularity is 1kbps. Each link can be applied different policies on both uplink and downlink.

5． Network Acceleration

QQSG-talented ACK Network Acceleration technology can reduce application respond time and forward delay, upgrade service experience, which will highly improve the experience of real-time-sensitive network applications, such as video conference, VOIP. It also can cut the re-forwarding time to save up the network resource.

By applying ACK acceleration, it will save 15%~30% responding time and the network resource.

6． High Security/High Stability

The device is bridged into the network transparently, without needing change the existing route plan，and also can avoid the attacks from outside 。It supports ByPass function. The system will switch to no-power bypass module when abnormal situation happens, such as hardware or software failure, power down, the applying network traffic will not be affected. The switching time is lower than 10ms.

7．A Whole Network Optimize Solution

QQSG can provide a whole Network Optimize Solution, including Application Layer Traffic Identification, Network traffic Surveillance, Resource Optimization, Network Security, which will rise the using efficient of network resources, lower the operation cost and increase the profit.

8． Excellent Supporting Team

QQ Tech. has a experienced technologist team, responsible for following, identifying and updating the new coming applications. can discover and follow new development of technologies and applications，publish new protocol identification software version regularly ，also can do develop new functions based on client-specified demands
