华为 Quidway 系列多协议路由器，支持 PPP、FR、X25、SLIP、HDLC 等网络协议，用户可通过各种广域网线路接入 Internet 及互联互访。 路由器内置安全防火墙、NAT、RADIUS 安全认证，以及 CALL BACK 等多项互联安全防护功能；并通过 CA 认证协议的验证和 IPSec 隧道协议，在 Internet 上构建安全可靠的网络通道，基于硬件的数据加密，将保密数据加密后在隧道上传输，加密数据有可靠的保密性但牺牲了效率；非保密数据可以通过一般性安全处理在隧道上传输，保证较高的转发速率。硬件加密的算法采用专门的芯片（经过国家相关部门批准）进行加密，密钥长度大于 128 位，并提供高强度的一次一密功能。配合完全自主知识产权的软硬件平台，提供网络的安全互联和数据的安全传输的安全解决方案。 而 "备份中心"的可靠性备份解决方案，实现多种线路之间的任意备份和业务分担，为网络提供业界最坚固的保护屏障，保证网络的可靠运行。-Huawei Quidway series of multi-protocol routers to support PPP, FR, X25, SLIP, HDLC and other network protocols, users can through various WAN lines and Internet access to the Internet visits. Built-in security firewall router, NAT, RADIUS authentication, and a number of other CALL BACK Internet security protection functions; And through CA and validation of the agreement IPSec agreement on the Internet to establish a secure and reliable network access, hardware-based data encryption, data encryption confidentiality the tunnels on the Tunnel, a reliable data encryptio
