摘　　要：随着各行各业数字化转型深入发展,政务、医疗、金融等行业入云业务提出很高的时延保障要求,而传统IP报文基于负载均衡转发,哈希算法中没有时延因子,导致以上高优先级业务未能确保在低时延平面传送和保障。结合云网融合发展趋势、IP承载网的IPv6+技术,探讨运营商在云网融合时代,实现IP承载网时延选路及保障方案。With the rapid development of digital transformation in all industries,government affairs,medical care,finance and other cloud services put forward high latency requirements,while traditional IP packets are forwarded based on load balancing scheme,and there is no delay factor in the hash algorithm,so it cannot be ensured that high-priority services are transmitted on the low-latency planes. Combined with the development trend of cloud and network convergence,IPv6+ technology on IP bearer network,it discusses the delay routing and guarantee scheme of IP Bearer Network of operators in the era of cloud network integration.
