### 基础知识
*安全半可靠UDP用户数据报协议*是@Kovri的两种加密@传输方式之一。
与@NTCP类似@SSU的*主要*目的是通过@隧道安全地传输@网内@I2NP消息但与@NTCP不同@SSU功能仅通过加密的[UDP](https://en.wikipedia.org/wiki/User_Datagram_Protocol)。
### 深度信息
- 与@NTCP一样@SSU也是面向连接的点对点数据传输
- 称为“半可靠”,因为@SSU将重复转发“未确认的”消息达到最大数量则丢弃
- @SSU还提供了几个独特的服务(除了它作为@传输层的功能):
- IP检测本地检测或使用[对等节点测试](https://geti2p.net/en/docs/transport/ssu#peerTesting)
- [网络地址转换](https://en.wikipedia.org/wiki/Network_address_translation)遍历 (使用[介绍人](https://geti2p.net/en/docs/transport/ssu#introduction)
- [防火墙](https://en.wikipedia.org/wiki/Firewall_%28computing%29)状态,如果执行,@SSU可以通知@NTCP如果外部地址或防火墙状态发生变化
### 备注
