In order to guarantee the QoS requirements of multiple services in airborne all-domain heterogeneous and flexible networks, we propose a novel multi-priority and multi-path based QoS routing (MP2R) protocol in this paper. In the protocol, in terms of the route effectiveness and reliability, the route cost penalty function is constructed based on the multi-priority M/M/1 queueingqueuing system with the preemptive-resume policy. The minimum value of the function is derived through the optimization theory, and the optimum routing solution is acquired. The simulation results show that the MP2R protocol not only has the capabilities of differentiation services for different kinds of traffic and QoS provision, but also can utilize the network resource rationally, avoid congestion, achieve the load balancing, and meet the requirements of airborne all-domain heterogeneous and flexible networks effectively.
为了保障机载全域异构柔性网络中多种优先级业务的不同QoS需求，提出一种多优先级多径QoS路由（multi-priority and multi-path based QoS routing，MP2R）协议。该协议综合考虑路由有效性和可靠性指标，并基于强拆继续型服务策略的多优先级M/M/1系统，构造了路由代价惩罚函数，通过最优化理论对函数求解最小值，从而制定最优路由选择策略。基于机载网络模型路由仿真研究结果表明，MP2R协议不仅具有多业务类型的区分服务和QoS保障能力，而且能够合理利用网络资源，避免网络拥塞，实现负载均衡，有效满足机载全域异构柔性网络的性能需求。
