| 网络事件 | 造成影响 | 能否感知 | 处理 |
|---|---|---|---|
| 非默认路由网卡IP变更 | 和变更网卡相关的局域网连接断开 | 能 | 重新进行mDNS广播 |
| 默认路由网卡IP变更 | 1. PMP 映射失效 2. P2P 映射失效，相关连接断开 3. 局域网连接断开 4. DHT 记录失效 | 能 | 1. 重新建立PMP映射 2. 重新获取网卡接口地址和外网出口地址 3. 重新进行mDNS广播 4. 重新广播到DHT网络 |
| 路由器LAN口IP改变WAN口IP不变 | 1. PMP网关地址失效 | 能 | 重新获取默认路由地址，刷新缓存 |
| 路由器WAN口IP改变 | 1. PMP 映射失效 2. P2P 映射失效，相关连接断开 3. DHT 记录失效 | 不能 | 1. 重新建立PMP映射 2. 重新获取外网出口地址 3. 重新广播到DHT网络 |
| network event | affect | can capture? | process |
|---|---|---|---|
| Non-default routing network card IP change | The LAN connection related to changing the network card is disconnected | Yes | Restart mDNS broadcast |
| Default routing network card IP change | 1. PMP mapping is invalid 2. P2P mapping is invalid and related connections are disconnected 3. LAN connection is disconnected 4. DHT records are invalid | Yes | 1. Re-establish PMP mapping. 2. Re-obtain the network card interface address and external network egress address 3. Re-broadcast mDNS 4. Re-broadcast to the DHT network |
| The router LAN port IP changes and the WAN port IP remains unchanged. | PMP gateway address invalid | Yes | Retrieve gateway address |
| Router WAN port IP changed | 1. PMP mapping is invalid 2. P2P mapping is invalid and related connections are disconnected 3. DHT record is invalid | No | 1. Re-establish PMP mapping 2. Re-obtain the external network egress address 3. Re-broadcast to the DHT network |
