中文摘要：

本研究基于Sqlite3数据库、多线程和策略路由等关键技术，通过为上网业务建立自由通路并对其进行维护，实现多网融合网关的网络资源共享功能。系统测试结果表明，自动路由通路较为畅通和稳定，且各用户均能合理地共享网络资源。

英文摘要：

Based on sqlite3 database, multi-threading, strategy routing and other key technologies, this paper re- alized heterogeneous network resource sharing in a multi-network integration gateway by automatic establishment and maintenance of the routing path. System test results showed that the automatic routing paths were quite smooth and sta- ble and the network resources can be reasonably shared among different users.
