云网融合中的网络基础设施演进探讨

Research on network infrastructure evolution for cloud-network convergence

以“网是基础、云为核心、网随云动、云网一体”为发展原则的云网融合数字信息基础设施,成为数字经济时代发展的坚实底座。从现有网络技术发展演进与基础设施融合创新动向出发,探究云网一体化发展中网络基础设施面临的挑战,并提出一种具有固移融合、算网融合和云光融合特征的新型超融合组网方案。该方案以云为纽带,实现园区、入云、云内与云间四部分的网络连通,为推动云网融合一体化发展提供了思路。同时,方案的各部分彼此独立,弹性伸缩适配业务需求,并自然适应未来新型业务复杂不确定性演进。

As a solid foundation in the era of digital economy,the digital information infrastructure has the cloudnetwork convergence feature of network as the foundation,cloud as the core,network moving with the cloud,and cloud network integration.Based on the evolution of existing network technologies and the convergence innovation trend of infrastructure,this paper proposes a new super convergence networking scheme with the characteristics of fixedmobile convergence,computing-network convergence and cloud-optical convergence.The proposed scheme with the cloud as the link realizes the connection of the access network,cloud access network,cloud intranet and inter cloud network,which provides an idea for promoting the integrated development of cloud and network.Meanwhile,each part of the scheme can develop independently,flexibly adapt to business requirements,and naturally adapt to the complex and uncertain evolution of new business in the future.
