 ## TODO
 
-节点心跳传输 geo 信息，geo 查询接口：`https://opendata.baidu.com/api.php?co=&resource_id=6006&oe=utf8&query=123.160.207.85`
+节点发送 open 请求后，如果是新节点则访问 geo 接口获取 geo 信息，并连带 host 和 port 信息提交到更新队列
 
-网关维护节点数据，节点发送心跳后，网关对比维护的数据，更新维护数据并将更新的部分追加到更新列表中。
+节点每次发送心跳后提供或计算 loss 和 rtt 信息，并对比 host 和 status，将需要更新的数据提交到更新队列
 
-网关定时发送更新配置
+网关监听并读取更新队列，定时发送更新数据到平台
 
 ### 长期
