1. High reliability and stability
After over a decade years of research experience in the data communication network field and studious research on broadband user's requirements, broadband solutions have won customers' trust in all respects, especially in hardware or software design and in systematic strong ability, and these routers can run reliably for a long time in harsh environments such as high temperature, poor ventilation and bad grounding.

2. Strong data-processing capability
GUANGDA 100M broadband routers adopts ARM9 and Intel IXP as their processors but further combine the switching chips, so this series of products has large throughput and high performance-to-price ratio. They secure the reliable and rapid operation of such kernel functional modules as NAT, VPN, P2P identification and control, and firewall in an environment of multi-user and large flow.

3. Flexible multi-WAN access
A maximum of 4 WAN ports can be used for networking; The access modes such as Ethernet, FTTB optical fiber, ADSL and cable are supported; The multi-line policies such as "bandwidth nesting", "intelligent routing" and "master/standby" are supported.

4. User-friendly and flexible flow control
Beside providing multiple users the broadband NAT network surfing, this router series supplies flexible speed limitation strategy. When the network bandwidth is idle, the bandwidth of each user will be automatically increased; When the network bandwidth is busy, the bandwidth will be averagely distributed, preventing bandwidth from being over occupied. The assistant strategies such as big flow host limitation mechanism, flow outburst factors and optional user punishment limitation bring various and feasible methods for network management.

5. Various behavior management policies
1)Identifies and controls the IM software like QQ and MSN on the application layer,and supports the white list,all which facilitates the network management of the enterprise.
2)Identifies the P2P application program on the application layer and carries out multiple strategies like blocking and speed limitation.
3)Stops the share, entertainment and shopping websites from being displayed on the screen on the basis of the database technology.
4)Corrsponding strategy database can be updated online.

6. Multiple anti-attack policies
GUANGDA broadband routers are strong in preventing attacks. They can make a correct statistics and detailed analysis on all types of packets such as ARP, IP, ICMP, TCP and UDP. The attacks can be automatically prevented once they are found. The alarm information will also be provided. Therefore, you need not worry about the security of your network.
For ARP cheat, GUANGDA provides IP-to-MAC binding, ARP-to-SCAN technology and free ARP and other mechanisms to secure the intranet; If working with GUANGDA private switching products, these router products can be armed with DHCP-Snooping. In this way, ARP cheat cannot hide itself and it is 100% sure that ARP cheat can be detected and prevented.

7. lround VPN functions
GUANGDA routers support VPN protocols such as L2TP, PPTP, GRE, IPIP and IPSec, and provide encryption algorithms, so that an overall solution can be provided to the construction of the remote office, the mobile office and the virtual private network.

8. User-friendly Web page
A simple and clear Web graphic interface is provided for configuration, so you can easily operate it even you are not professional.
