Carrier-Level QoS Policies
Supports priority retagging and complicated flow classification based on VLAN, MAC, source address, destination address, IP or priority to better streamline carrier’s services. Supports flexible bandwidth control policies and supports port-/flow based flow limit, and ensuring the line speed forwarding of each port to make sure the high quality of video, audio and data services. Supports 8 priority queues by each port. Supports multiple queue schedule algorithms such as SP, WRR, or “P plus WRR”
Innovative virtual Cluster Switching Technique
TVSS(Techroutes Virtual Switch System):
Virtualize multiple physical devices into one. The performance, reliability and management of the virtual system are superior to the physical ones.
Improved Performance: TRVSS makes full use of each link in the physical devices, which avoids STP blocking the link and protects the original link to the maximum extent;
High Reliability: Based on the advanced distribution mechanism and efficient cross-physical link aggregation link function, the logic control plane, service control plane and service data plane are separated. Thus, the device can support continuous layer3 routing forwarding, avoiding service interruption as a result of a single point of failure; Easy Management: TRVSS realizes single IP management, greatly improving the networking efficiency and lowering the operating cost.
Easy Management: TRVSS realizes single IP management, greatly improving the networking efficiency and lowering the operating cost.

Varied Service Characteristics
Supports layer-2 and layer-3 multicast routing protocol, which enable the device can access to IPTV, HD video surveillance and HD video conference. Supports layer-3 routing protocol and super-large routing table capacity, which enables the device is available in large campus networks, enterprise networks and industry networks. Supports MPLS multi-VRF and layer-2 VPN.
Industrial Ethernet Ring with Zero Delay and Zero Packet Loss
Supports industry-level EAPS and ERPS, and their protection recovery time is less than 50ms. Their high reliability is represented by the null packet loss, which has been proved by many years of application in the Grid, rail transportation and defense systems.
Complete Security Mechanism
Equipment-Level Security: The advanced hardware infrastructure design realizes the level-based packet schedule and packet protection, prevents DoS-/TCP related SYN Flood, UDP Flood, Broadcast Storm or large traffic attacks, and supports level-based command line protection, endowing different levels of users with different management permissions. Security Authentication Mechanism: IEEE 802.1x, Radius and TRTacacs+ Enhanced Service Security Mechanism: supports the plaintext or MD5 authentication of relevant routing protocol, URPF, deep inspection of hardware packet, control packet and data packet and filtering technology.
Innovative Energy-Saving Design
Intelligent power management: The power system of TR-S3900 series supports real-time monitoring the device and the slow-start. It is also power-saving. Intelligent fan management system: The fan systems of S3900 Series supports automatic speed regulation, which efficiently slow the fan speed and mitigate the noise. Complies with the international standard IEEE 802.3a.
Flexible and Convenient Management and Maintenance
Supports management modes such as the console ort, Telnet, SSH, etc. Supports the WEB management mode, which is easy and efficient so that it makes installation and debugging convenient. Supports TFTP- patterned file upload/download management. Supports ISSU (In-Service Software Upgrade).
