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 between...
可以添加额外的Spine交换机并将其连接到每个Leaf ,从而进一步增加容量。同样,当端口密度成为问题时,可以无缝添加新的Leaf 交换机。在这两种情况下,网络都不必为基础设施的这种扩展(“横向扩展”)而重新设计,也没有停机时间。 参考文献: https://ebrary.net/168922/computer_science/traditional_three_layer_network_ar...
Spine-Leaf体系架构是由Spine和Leaf这两个交换层组成的数据中心网络拓扑结构。Leaf层由访问交换机组成,汇聚来自服务器的流量,并直接连接到Spine或网络核心。Spine交换机在全网格拓扑中互连所有Leaf交换机。上图中,绿色节点代表交换机,灰色节点代表服务器。在绿色节点中,最上面的是Spine节点,下面是Leaf节点。 Spine-Leaf...
Leaf-spine,也叫leaf-spine architecture,或leaf-spine network topology,其中文意思(及常用翻译)是:叶脊网络架构,或叶脊网络拓扑。它指的是一种新型的两层网络连接结构。这里的leaf(叶子),指的是端点或边缘层网络设备。而spine(脊柱),则是核心、中心层网络设备,它负责与leaf节点进行连接。 与传统的三层(3-tier)...
Leaf/Spine网络架构下,各节点都是具备L3功能的交换机,搭建起的是一个全三层的IP Fabric。 IP这种协议在设计之初就充分地考虑了环路规避、多路径转发、高可靠、多路径等因素,无需再引入STP或配置更为复杂的堆叠和MC-LAG——结合BGP路由和ECMP的负载平衡设计,园区网络中所有的物理线路理论上来说都可被充分利用,在不...
其中第五代的架构叫做Jupiter Network Fabrics,可以视为一个三层Clos。leaf交换机还是作为ToR,向北连接到叫做 Middle Block的spine交换机。Middle Block和ToR组成一个集群(相当于Facebook的Server Pod,内部是一个二层Clos)叫做Aggregation Block Superblock。MiddleBlock向北还有一层super spine也就是Spine Block。
针对以上问题,网络工程师们提出了一种新的数据中心设计,称作基于 Clos 网络的Spine-and-Leaf 架构(Clos network-based Spine-and-Leaf architecture,中文也翻译成叶脊网络)。事实已经证明,这种架构可以提供高带宽、低延迟、非阻塞的服务器到服务器连接。
A spine-leaf architecture is data center network topology that consists of two switching layers—a spine and leaf. The leaf layer consists of access switches that aggregate traffic from servers and connect directly into the spine or network core. Spine switches interconnect all leaf switches in a...
