FogConnet 是用于P2P网络中连接、调度、传输等功能于一体的组件
- 支持多种传输控制协议（UDP、QUIC、RTC、KCP、uTP、SCTP等）
- 探测NAT类型，并收集和维护用于P2P连接的
<IP:Port>列表 - 支持双向 “打洞” 和高级端口预测
- NAT类型最优匹配组合策略
- 连接控制与物理距离最近原则
- 所有网络信号采用事件机制处理
- 对资源消耗极少（一般运行状态下内存占用3-5M，峰值不超过50M）
- API简单、易懂，支持多种方式接入
FogConnect depends on following packages:
- Linux(e.g. Ubuntu, OpenWrt), Windows, MacOS, Android, iOS
Install common deps:
sudo apt-get install git make
Install dependencies:
sudo apt-get install openssl libssl-dev libwebsockets-dev libjansson-dev libevent-dev libglib2.0-dev
make
平均P2P建立连接时间：1.2~2秒
