在Spine-and-Leaf 架构中,任意一个服务器到另一个服务器的连接,都会经过相同数量 的设备(除非这两个服务器在同一 leaf 下面),这保证了延迟是可预测的,因为一个包 只需要经过一个 spine 和另一个 leaf 就可以到达目的端。 3 Overlay 网络 现代虚拟化数据中心的网络要加速应用部署和支持 DevOps,必须满足特定的...

1/16[译] 数据中心网络:Spine-Leaf 架构设计综述译者序本文内容翻译自 Cisco 的白皮书 Cisco Data Center Spine-and-Leaf Architecture: Design Overview(2016),翻译非逐字逐句,请酌情参考。搜索 spine-leaf 资料时看到这篇非常棒的文档,故通过翻译的方式做个笔 记顺便加深理解(不知是否有没有中文版)。本文翻译...
在Spine-and-Leaf 架构中,任意一个服务器到另一个服务器的连接,都会经过相同数量的设备(Server -> Leaf -> Spine Switch -> Leaf Switch -> Server),这保证了延迟是可预测的,因为一个包只需要经过一个 spine 和另一个 leaf 就可以到达目的端。 Spine-Leaf 的工作原理 Leaf Switch:相当于传统三层架构中的...
顾名思义,该架构共有一个脊(Spine)层和一个叶(Leaf)层,包括脊交换机(spine switches)和叶交换机。 | Spine-Leaf架构 每个叶交换机都连接到所有脊交换机,脊交换机不直接相互连接,形成一个 full-mesh 拓扑。 在Spine-and-Leaf 架构中,任意一个服务器到另一个服务器的连接,都会经过相同数量的设备(Server ->...
If this architecture is folded in half and turned on its side, it becomes the spine-leaf architecture discussed previously, as shown in Figure 6-5. Figure 6-5 Folded three-layer Clos network architecture model The number of access connections is still equal to the number of connections...
In a Layer 2 spine-leaf design, TRILL or SPB take the place of STP. All hosts are linked to the fabric and offer a loop-free route to their EthernetMedia Access Control (MAC) addressthrough a shortest-path-first computation. In a Layer 3 design, each link is routed. This approach is...

Familiarity: We used this model for over a decade, so network engineers are familiar with this design and the protocols we use. Disadvantages There are, however, some disadvantages, which is why the spine-leaf architecture is gaining popularity. ...
Why Choose Spine-Leaf? • Super Fast: Minimal delays, making it perfect for high-speed applications. • Highly Scalable: Easily expands by adding more leaf switches. • Reliable: Redundant connections prevent downtime. Drawbacks: • Complex Setup: Requires careful design and significant cablin...
