动态决策域多业务接纳控制研究

基于无信令判决的流感知接纳控制实现了多业务接入区分,为不同业务提供了差异化性能保障.由不同业务状态指标构建的链路状态空间能够对业务流间的相互影响进行响应,实时调整进程中不同业务流的分布.在模糊化状态指标门限的基础上,映射状态空间的动态决策域,并构建对应判决表,节点仅由业务感知类型和判决表执行业务区分的接纳控制,保障已接纳业务请求的服务质量.推导出链路状态转移的稳定性条件是弹性流不过载,仿真证明了链路公平速率的稳定性.

Dynamic Decision Domain Based Admission Control Algorithm for Multi-service Network

Flow-aware admission control based on no singling decision provided diversified performance for different services by distinguishable access in multi-service.The link state spaces constructed with different service metrics could respond to the change state.And different flows in progress were modulated to rational distribution in real-time. The link state space was mapped to dynamic decision domain based on fuzzying the threshold of service state metrics.The link decision table was made at the same time.The node assured the requested quality of service for services in progress according to the service-aware category and decision table.The stable condition of the link state transfer was deduced that elastic flows are in under-load.Simulation result shows that the link fair rate changes steadily.
