【新功能！】负载均衡SLB支持UDP协议了！

尊敬的阿里云SLB用户：

您好，为了满足视频、 DNS 、 金融行情推送 等用户场景需求，阿里云负载均衡SLB已经 支持UDP协议 ，目前已经所有地域上线，并且对所有用户开放。用户不需再提交工单进行申请，请知晓。

阿里云SLB团队
2015年12月1日

＝＝＝＝＝＝＝＝附上UDP FAQ和相关文档

1、UDP相关FAQ

Q: UDP协议与TCP协议有什么区别？
A: TCP协议是面向连接的协议，在正式收发数据前，必须和对方建立可靠的连接。UDP是面向非连接的协议，它在数据发送前不与对方先进行三次握手，而是直接进行数据包发送传送。这两种协议分别适用于不同的应用场景。

Q: UDP协议适用于哪些场景？
A: UDP协议主要适用于关注实时性而相对不注重可靠性的场景，如视频聊天、金融实时行情推送、DNS、物联网等。

Q: 谁可以申请试用UDP协议？
A: 有SLB实例或者多个ECS实例，且有UDP协议场景需求的用户都可以通过工单申请试用UDP协议，预计一个月左右对所有用户开放UDP协议。

Q: 目前哪些地域支持UDP协议？
A: 目前所有抵御都已支持UDP协议。

Q: UDP协议的健康检查如何配置？
A: 与当前四层TCP协议一致，建议配置参数：响应超时时间 10s；健康检查间隔 5s；不健康阈值 3；健康阈值 3。
