P2PAPP is the most import concept in this project, one P2PApp is able to map the remote service(mstsc/ssh) to the local listening. The main job of re-development or restful API we provide is to manage P2PApp.

## RoadMap
Short-Term:
1. Support IPv6.
2. Support auto run when system boot, setup system service.
3. Provide free servers to some low-performance network.
4. Build website, users can manage all P2PApp and devices via it. View devices' online status, upgrade, restart or CURD P2PApp .
5. Provide wechat official account, user can manage P2PApp nodes and deivce as same as website.

8. Optimize our share scheduling model for different network operators.
9. Provide REST APIs and libary for secondary development.
10. Support UDP at application layer, it is easy to implement but not urgent due to only a few applicaitons using UDP protocol.
11. Support KCP protocol underlay, currently support Quic only. KCP focus on delay optimization,which has been widely used as game accelerator,it can sacrifice part of bandwidth to reduce timelag.
12. Support Android platform, let the phones to be mobile gateway .
13. Support SMB Windows neighborhood.
14. Direct connection on intranet, for testing.

华为鸿蒙:
1. 允许应用后台运行:进入设置 → 搜索进入 应用启动管理 → 关闭 OpenP2P 的 自动管理 开关 → 在弹框中勾选 允许后台活动
2. 避免应用被电池优化程序清理:进入设置 → 搜索进入电池优化 → 不允许 →选择所有应用 → 找到无法后台运行的应用 → 设置为不允许
3. 关闭省电模式:进入设置 → 电池 → 关闭 省电模式 开关
4. 保持设备网络连接:进入设置 → 电池 → 更多电池设置 → 开启 休眠时始终保持网络连接 开关。
5. 给后台运行的应用加锁:打开应用后 → 进入多任务界面 → 下拉选中的卡片进行加锁 → 然后点击清理图标清理其他不经常使用的应用
6. 设置开发人员选项中相关开关:进入设置 → 搜索进入 开发人员选项 → 找到 不保留活动 开关后关闭 → 并在 后台进程限制 选择 标准限制
华为手机:
进入”设置“,搜索并进入“电池优化“界面,选中 OpenP2P 程序,不允许系统对其进行电池优化;
进入”设置“,进入”应用管理“界面,选中 OpenP2P 程序,点击”耗电情况“,开启”允许后台活动“即可;
小米手机:
进入”设置“,进入”更多应用“界面,选中 OpenP2P 程序,点击”省电策略“,设置为”无限制“;
进入”设置“,进入”特色功能“界面,选中”游戏加速“,将其关闭即可;
OPPO手机
进入”设置“,进入”应用管理“界面,选中 OpenP2P 程序,点击”耗电保护“,关闭所有设置项即可;
VIVO手机
