BGP高防是什么意思呢？BGP高防服务器租用 45.250.42.X

大家都知道BGP高防是DDOS流量攻击的首选防御之一，那么BGP高防到底是什么？BGP高防有什么优势呢？我给大家讲一下

BGP高防协议是什么？

BGP协议指边界网关协议（Border Gateway Protocol），简称BGP，主要用于互联网AS（自治系统）之间的互联，BGP协议的最主要功能在于控制路由的传播和选择最好的路由

BGP高防的原理是什么？

BGP高防的原理是通过把域名解析到高防IP，并配置源站IP，所有公网流量都必须经过高防IP机房，通过端口协议转发的方式将访问流量通过高防IP转发到源站IP，同时将恶意攻击流量在高防IP上进行清洗过滤后将正常流量返回给源站IP，从而确保源站IP稳定访问

BPG线路有以下功能特点：

单IP多线接入，通过BGP可以实现一个IP对应电信、联通、移动、长城、教育网等不同线路的带宽，而不需要服务器端配置多个IP。BUP会自动选择最佳途径，使运行速度加快。而且在多线路中有途径发生了故障，BGP会自动选择最佳路线，从而不会影响运行。

使用BGP高防可以解决跨运营商访问慢、部分小运营商访问不稳定的情况

从运营商网络质量来看，BGP带宽是中国内地地域目前最昂贵的、线路质量也是最好的线路，对于延迟要求比较苛刻的业务（如即时对战游戏）也会优先选用BGP线路
