多年来，卫星网络在商业和学术界都得到了广泛的研究，文献中报道了许多重要的路由算法。然而，现有的路由算法很少关注路由生存能力与路由计算和存储开销之间的权衡。由于拓扑动力学的原因，RIP或OSPF等传统路由协议难以有效地应用于近地轨道卫星网络。根据基于虚拟节点的虚拟拓扑模型，提出了一种全新的低轨道卫星网络全分布式路由协议——分布式流量均衡路由（DTBR）。该协议不仅保证了路由的生存性，提供了流量均衡的能力，而且仅由于故障卫星的信息泛滥而产生的额外计算和存储开销很少。仿真结果验证了本文方法的有效性。
Satellite networks have been widely investigated both in the business and academia for many years, with many important routing algorithms reported in the literatures. However, fewer existing routing algorithms focus on the trade-off between the routing survivability and the routing computation and storage overheads. Due to topological dynamics, it is difficult to effectively apply the conventional routing protocols such as RIP or OSPF to Low Earth Orbit (LEO) satellite networks. According to the virtual topology model based on virtual node, this paper propose a new fully distributed routing protocol for LEO satellite networks, called Distributed Traffic Balancing Routing (DTBR). The proposed protocol not only guarantees the routing survivability and provides the ability of traffic balancing, but also result in few additional computation and storage overheads only deriving from the information flooding of failed satellites. Simulation results demonstrate positive conclusions of our methods.
