DBS因特网接入系统中隧道机制的研究和实现

Research and Implementation of Tunneling Mechanism in DBS Internet Access System

介绍了直接广播卫星(DBS)因特网接入系统的结构和路由配置。针对下行数据和上行数据经由分离的信道传输的特点,在上行信道上采用隧道机制传输IP数据报,并且给出了这一技术在Linux平台上的实现。

In this paper, the architecture and routing configuration of DBS Internet access system is introduced. According to the features of separated forward and backward links, tunneling mechanism for IP dadagram transportation on backward link is employed and realized on Linux platform.
