摘　　要：为了克服智能光网络(ASON)在承载基于业务协定等级(SLA)业务期间因链路资源失效而中断连接,提出一种基于差异化SLA业务的自适应自愈生存技术。该技术统筹考虑链路资源对SLA业务的贡献度以及链路资源陷阱问题,通过循环计算为全网任意节点提取出可用路由,并引入权重机制分别为差异化的SLA业务量身制定局向资源和自愈资源。同时根据共享风险链路组(SRLG)的模型思想,最大化局向资源的服务能力最小化自愈资源的使用率。指标显示,该技术可提供科学的自适应生存能力。In order to overcome the disconnection caused by link resource failure when ASON is carrying SLA service,an adaptive self-healing survival technology based on differentiated SLA service is proposed.The technology considers the contribution of link resources to SLA services and the problem of link resource traps,extracts the available routes for any node in the whole network through cyclic calculation,and introduces the weight mechanism to tailor the local resources and self-healing resources for differentiated SLA services.At the same time,according to the model idea of shared risk link group(SRLG),the service capacity of local resources is maximized and the utilization rate of self-healing resources is minimized.The index shows that the technology can provide scientific adaptive survivability.
