3. Layer2 模式 每个service会有集群中的一个node来负责。当服务客户端发起ARP解析的时候,对应的node会响应该ARP请求,之后,该service的流量都会指向该node(看上去该node上有多个地址)。 并不是真正的负载均衡,因为流量都会先经过一个node后,再通过kube-proxy转给多个endpoints。如果该node故障,MetalLB会迁移 IP到另...

-> Space::loadBalance() 进入Space::loadBalance() 之后,就要看 pRoot_ 的状态了。 如果当前 pRoot_ 是 CellData 类型的,则调用的是 CellData::balance,没什么特别的事情好做的。 如果当前 pRoot_ 是 InternalNode 类,则调用的是 InternalNode::balance,这里面就比较复杂了,会自顶向下的尝试对各个层级的...
