一 重要的概念https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#%E4%B8%80-%E9%87%8D%E8%A6%81%E7%9A%84%E6%A6%82%E5%BF%B5
1.1 什么是 Dubbo?https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#11-%E4%BB%80%E4%B9%88%E6%98%AF-dubbo
1.2 什么是 RPC?RPC原理是什么?https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#12-%E4%BB%80%E4%B9%88%E6%98%AF-rpcrpc%E5%8E%9F%E7%90%86%E6%98%AF%E4%BB%80%E4%B9%88
1.3 为什么要用 Dubbo?https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#13-%E4%B8%BA%E4%BB%80%E4%B9%88%E8%A6%81%E7%94%A8-dubbo
1.4 什么是分布式?https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#14-%E4%BB%80%E4%B9%88%E6%98%AF%E5%88%86%E5%B8%83%E5%BC%8F
1.5 为什么要分布式?https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#15-%E4%B8%BA%E4%BB%80%E4%B9%88%E8%A6%81%E5%88%86%E5%B8%83%E5%BC%8F
二 Dubbo 的架构https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#%E4%BA%8C-dubbo-%E7%9A%84%E6%9E%B6%E6%9E%84
2.1 Dubbo 的架构图解https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#21-dubbo-%E7%9A%84%E6%9E%B6%E6%9E%84%E5%9B%BE%E8%A7%A3
2.2 Dubbo 工作原理https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#22-dubbo-%E5%B7%A5%E4%BD%9C%E5%8E%9F%E7%90%86
三 Dubbo 的负载均衡策略https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#%E4%B8%89-dubbo-%E7%9A%84%E8%B4%9F%E8%BD%BD%E5%9D%87%E8%A1%A1%E7%AD%96%E7%95%A5
3.1 先来解释一下什么是负载均衡https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#31-%E5%85%88%E6%9D%A5%E8%A7%A3%E9%87%8A%E4%B8%80%E4%B8%8B%E4%BB%80%E4%B9%88%E6%98%AF%E8%B4%9F%E8%BD%BD%E5%9D%87%E8%A1%A1
3.2 再来看看 Dubbo 提供的负载均衡策略https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#32-%E5%86%8D%E6%9D%A5%E7%9C%8B%E7%9C%8B-dubbo-%E6%8F%90%E4%BE%9B%E7%9A%84%E8%B4%9F%E8%BD%BD%E5%9D%87%E8%A1%A1%E7%AD%96%E7%95%A5
3.2.1 Random LoadBalance(默认，基于权重的随机负载均衡机制)https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#321-random-loadbalance%E9%BB%98%E8%AE%A4%E5%9F%BA%E4%BA%8E%E6%9D%83%E9%87%8D%E7%9A%84%E9%9A%8F%E6%9C%BA%E8%B4%9F%E8%BD%BD%E5%9D%87%E8%A1%A1%E6%9C%BA%E5%88%B6
3.2.2 RoundRobin LoadBalance(不推荐，基于权重的轮询负载均衡机制)https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#322-roundrobin-loadbalance%E4%B8%8D%E6%8E%A8%E8%8D%90%E5%9F%BA%E4%BA%8E%E6%9D%83%E9%87%8D%E7%9A%84%E8%BD%AE%E8%AF%A2%E8%B4%9F%E8%BD%BD%E5%9D%87%E8%A1%A1%E6%9C%BA%E5%88%B6
3.2.3 LeastActive LoadBalancehttps://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#323-leastactive-loadbalance
3.2.4 ConsistentHash LoadBalancehttps://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#324-consistenthash-loadbalance
3.3 配置方式https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#33-%E9%85%8D%E7%BD%AE%E6%96%B9%E5%BC%8F
四 zookeeper宕机与dubbo直连的情况https://github.com/qystack2020/JavaGuide/blob/master/docs/system-design/data-communication/dubbo.md#%E5%9B%9B-zookeeper%E5%AE%95%E6%9C%BA%E4%B8%8Edubbo%E7%9B%B4%E8%BF%9E%E7%9A%84%E6%83%85%E5%86%B5
