用于异构网络融合的用户前置设备
摘要：
本发明公开了一种用于异构网络融合的用户前置设备，其上联侧有射频接入端口(HFC Port)和第一数据收发端口(Uplink Port)；它还包括一外部总线，射频接入端口(HFC Port)通过数字Tuner模块、TS流解析模块(TS Module)与外部总线相连；上联侧的第一数据收发端口(Uplink Port)通过第一数据收发模块(Module 1)与外部总线相连；下联侧的第二数据收发端口(Downlink Port)通过第二数据收发模块(Module 2)与外部总线相连；它还包括一个基于VPN技术的路由控制单元，与总线连接；在已有以太网连接的基础上，该路由控制单元再建立一个包含HFC下行通道的虚拟网络通道；该虚拟网络通道通过PPP协议，由远端服务器提供DHCP服务，分配IP地址，根据用户设备访问请求和应用服务的路由信息选择上联侧的承载通道。
摘要（英）：

The invention discloses user preposition equipment for heterogeneous network fusion. The uplink side of the equipment is provided with a radio-frequency access port (HFC Port) and a first data transceiving port (Uplink Port); the equipment also comprises an external bus, and the radio-frequency access port (HFC Port) is connected with the external bus through a digital Tuner module and a TS stream resolving module (TS Module); the first data transceiving port (Uplink Port) of the uplink side is connected with the external bus through a first data transceiving module (Module 1); a second data transceiving port (Downlink Port) of the downlink side is connected with the external bus through a second data transceiving module (Module 2); the equipment also comprises a VPN technology-based routing control unit which is connected with the bus; based on the existing Ethernet connection, the routing control unit reestablishes a virtual network channel comprising an HFC downlink channel; and a far-end server supplies DHCP service and distributes an IP address to the virtual network channel through PPP protocols, and the virtual network channel selects a loading channel of the uplink side according to user equipment access request and routing information of application service.
