随着5G、云计算和边缘计算的快速发展,城域网作为连接用户与核心网络的关键枢纽,面临带宽、时延和灵活性的多重挑战。以宽带远程接入服务器(broadband remote access server,BRAS)为核心研究对象,回顾其从传统硬件封闭架构向控制面和用户面(control-plane/user-plane,CU)分离的演进历程,并探讨新型数据处理器(data processing unit,DPU)网卡技术的发展历程和技术优势。其中,重点分析了DPU网卡实现BRAS转发面的技术方案与难点,为运营商构建高弹性、低时延的下一代城域网提供理论参考。
With the rapid development of 5G
cloud computing
and edge computing
metropolitan area networks (MANs)
as critical hubs connecting users and core networks
face multifaceted challenges in bandwidth
latency
and flexibility. Focusing on the broadband remote access server (BRAS)
its evolution from traditional closed hardware architectures to control-plane/user-plane (CU) separation was reviewed
and the technological advancements and advantages of the emerging data processing unit (DPU) network interface cards were explored. In particular
the technical solutions and challenges of implementing the BRAS forwarding plane using DPU-based network cards were analyzed in depth
providing theoretical references for operators to build highly resilient and low-latency next-generation MANs.
