摘　　要：随着卫星通信技术的日益发展,系统内部多信道并存的现象越来越普遍,信道间传输的业务容易引起相互干扰,单纯运用传统路由器很难完成系统中不同信道间的业务完整隔离;同时,多信道卫星通信系统网络拓扑结构复杂,易引起控制混乱等问题。针对这些问题,提出一种基于虚拟局域网(Virtual Local Area Network,VLAN)的多信道卫星通信地面系统的设计方法。该方法充分利用网络划分VLAN技术的隔离性和安全性特征,结合多信道通信技术使用多个信道同时传输业务的特征,提升特征维度,实现高效、可靠的多信道卫星通信,具有易于硬件实现的特点,提高网络通信的吞吐量。With the increasing development of satellite communication technology,the phenomenon of multiple channels coexisting within the system is becoming more and more common,and the services transmitted between the channels are prone to cause mutual interference,and it is difficult to complete the complete isolation of services between different channels in the system simply by using the traditional router;at the same time,the network topology of the multichannel satellite communication system is complicated,which is prone to cause problems such as chaotic control.Aiming at these problems,a Virtual Local Area Network(VLAN)based design method for multi-channel satellite communication ground system is proposed.The method makes full use of the isolation and security features of network segmentation VLAN technology,combines the features of multi-channel communication technology that uses multiple channels to transmit services at the same time,and enhances the feature dimensions to realize efficient and reliable multi-channel satellite communication with easy hardware implementation and improve the throughput of network communication.
