| 摘要: |
| 为满足短波用户接入Internet网络中的要求，结合软交换的思想，设计了一种短波接入网关
。主要通过tun/tap完成有线网数据的获取，通过协议代理完成不同链路之间的协议转换，
通过对短波链路物理层设备的控制完成短波链路数据的交互。通过搭建室内平台，验证了短
波网络与Internet网络的联通性，以及与其他短波网关相比在功能上的优势。 |

| Abstract: |
| In order to meet the demand of the HF(High Frequency) user who wants to join in
the Internet, according to the theory of the soft switch, a HF access gateway is des
igned. The virtual ethernet device(tun/tap) is used to make up the frame catch
in net-layer. And some protocol clients are used to transform different protoc
ol between different channels. For the sake of data transmission in the HF chann
el,the HF access gateway has to control the physical layer device. A test platf
orm is built up in the lab, and the result shows the connection of the HF user a
nd the Internet. Finally, the excellence of the HF access gateway is point out t
hrough comparing it with other HF access gateway. |
