针对用户对通信业务的要求越来越高,网络管控能力逐渐减弱,难以保障业务的服务质量的问题,设计并实现了资源预留系统,该系统可以为数据流预留资源,保证业务的QoS需求.该系统建立在软件定义网络架构上,并以带宽预留的蚁群算法为路由算法.提出了一种新算法BRACO,该算法为数据流计算的路径可以满足一定的时延和丢包率的要求.通过搭建仿真网络,验证了该系统可以为业务预留资源,并满足业务的QoS要求.
In view of the fact that the users are getting more and more requirements for communication services and the network management and control capabilities are gradually weakened, it is difficult to guarantee the service quality of services. A resource reservation system is designed and implemented. The system can reserve resources for data flows and ensure QoS Requirements.The system is based on the software-defined network architecture and uses the bandwidth-reserved ant colony algorithm as the routing algorithm.A new algorithm BRACO is proposed, which calculates the path of the data stream to meet the delay and packet loss Rate requirements.By setting up a simulation network, the system verifies that the system can reserve resources for the service and meet the QoS requirements of the service.
