交换机传输网络在卫星地球站的应用

扫码查看
广东卫星地球站交换机传输网络通过使用2层VLAN划分不同虚拟网络,缩小广播域,提高带宽资源的使用效率.在远距离传输的链路上,使用链路聚合技术LACP的方式实现链路冗余备份,提高传输链路的可靠性.在交换机之间互联的端口使用ACL(Access Control List,访问控制列表),实现了对网络中IP报文的精准过滤和通过,提高了网络环境的安全性和可靠性.
Application of Switch Transmission Network in Satellite Earth Stations
The switch transmission network of Guangdong Satellite Earth Station mainly uses 2-layer VLANs to divide different virtual networks,narrow the broadcasting domain,and improve the efficiency of bandwidth resource utilization.On the long-distance transmission link,the link aggregation technology LACP is used to realize link redundancy backup and improve the reliability of the transmission link.The use of ACL(Access Control List)on the interconnected ports between switches enables precise filtering and passing of IP packets in the network,ensuring the security and reliability of the network environment.
