摘　　要：宽带接入网络及相关业务的迅猛发展对城域网业务边缘节点提出更高要求。文章首先介绍现网BRAS的部署情况以及存在的设备可靠性低、建设成本高、设备资源利用率低、运维复杂等问题,然后提出BRAS设备的池组化组网架构,并阐述基于池组化技术的BRAS部署及组网方案的发展趋势,最后重点分析BRAS部署及组网方案不同演进阶段的关键技术(包括双机热备、虚拟集群、Pool技术及基于SDN的云化网关等)。With the rapid development of broadband access network and related business, metropolitan area network business edge node should perform better. This paper ifrst introduces the current network deployment of BRAS and low reliability of equipment, high construction costs, low equipment resources utilization rate, complex operations and so on. Then aiming at these problems, it proposes a pooling networking architecture of BRAS, expounds the BRAS deployment based on pooling technology and the development trend of networking schemes, and ifnaly analyzes the key technologies of BRAS deployment and networking scheme in different evolution stages including double machine hot standby, virtual cluster, Pool technology and SDN-based cloud gateway, etc.
