动态DNS+网关分离的分布式数据中心互联方法

DDNS + gateway separation method for interconnect of distributed data center

分析了高校多校区分布式数据中心现存互联问题,在传统单侧网关和RHI+网关分离互联方式的基础上,提出了一种DDNS+网关分离的互联思路,以前端DDNS技术实现业务流量站点的选择,利用SLB设备配合VMware实现用户访问的不间断。在实验环境中,在线或新上线用户在虚拟机漂移前后能够快速访问到数据中心的同一种业务,适用于业务流量大、IP规划复杂、连续性要求高的应用场景。该互联方法必须在数据中心的边缘增加DDNS设备,在两地的数据中心交换机侧旁挂SLB设备。

The multi-campus university distributed data centers interconnected problems existing in the traditional gateway were analyzed and based on RHI + gateway unilateral separation methods on the Internet, a DDNS + gateway interconnection separation idea to front-end technology was proposed to achieve business traffic sites DDNS selection, using the device with the VMware SLB to achieve uninterrupted user access. In a lab environment, online or new on-line users drifting around in a virtual machine can fast access to the data center to the same kind of business, suitable for the business flow, IP planning complex continuous demanding scenarios. The interconnection method must increase DDNS equipments in the data center edge, hanging the SLB device next to the switch side of data centers in both places.
