Spine 和 Leaf 交换机之间通过 ECMP(Equal Cost Multi Path)动态选择多条路径。区别在于,Spine 交换机现在只是为 Leaf 交换机提供一个弹性的 L3 路由网络,数据中心的南北流量可以不用直接从 Spine 交换机发出,一般来说,南北流量可以从与 Leaf 交换机并行的交换机(edge switch)再接到 WAN router 出去。 Spine/Le...

一个三级/四层的Leaf/Spine架构的园区网络组网模型: 楼层内,接入层交换机作为Leaf,楼层汇聚交换机作为Spine,构成第一级网络 楼栋内,楼层汇聚交换机作为Leaf,楼栋汇聚交换机作为Spine,构成第二级网络 园区内,楼栋汇聚交换机作为Leaf,园区汇聚交换机作为Spine,构成第三级网络 01、更优秀的横向扩展性 随着园区规模的从小...
Spine-Leaf 架构是数据中心网络拓扑,它由两个交换层组成,分别是 Spine 和 Leaf。Leaf 层由接入交换机组成,这些交换机会对来自服务器的流量进行汇聚并直接连接到 spine 或网络核心。Spine 交换机可以一种全网格拓扑与所有 leaf 交换机实现互连。 Spine-Leaf架构与传统网络设计有何不同? 传统上,数据中心网络基于三层...

With the exponential growth of servers and the extension of the data center switching layer, the spine-leaf architecture is gradually replacing the traditional three-tier architecture as a rising star. So how much do you know about spine-leaf architecture? How do you build a spine-leaf ...
Why are spine-leaf architectures becoming more popular? Building a spine-leaf architecture with HPE Aruba Networking CX Switching How does a spine-leaf architecture differ from traditional network designs? Traditionally, data center networks were based on a three-tier model: ...
Why leaf-spine structure is needed The traditional data center computing network consists of an access layer, an aggregation layer and a core layer. The traditional three-tier architecture has many shortcomings. 1.Waste of resources. In the traditional three-layer structure, a lower-layer switch ...
