针对卫星宽带网络业务的多样性,提出了一种基于业务QoS(服务质量)需求和星间链路信息的多路径并行路由方案。该方案利用星间链路历史信息和准实时信息进行路由预规划,并基于星间链路实时信息和业务QoS需求对预规划的路由方案进行动态调整,实现业务数据在源节点和目的节点之间进行多路径并行传输。该方案不仅确保了业务传输的高可达性,而且使整个卫星网络链路资源得到充分利用,实现负载均衡。
Aiming at the diversity of satellite broadband network services, a multi-path parallel routing scheme based on QoS requirements and inter-satellite link information is proposed. The scheme uses the inter-satellite link historical information and quasi-real-time information to pre-route the routing and dynamically adjusts the pre-planned routing scheme based on the inter-satellite link real-time information and service QoS requirements to implement the service data at the source node and the destination node Multi-path parallel transmission between. This scheme not only ensures high reachability of service transmission, but also makes full use of the entire satellite network link resources to achieve load balancing.
