分区计算
能分区计算的场景： 淘宝（根据商品分区），游戏（根据服务器分区）
不能分区计算的： QQ, 铁路买票。（关系网络每个点都有联系，不能划分开）
Peer-to-peer Architectures
-
From a high-level perspective, the nodes that
constitute a peer-to-peer system are all equal. -
System functions are represented by every node
-
Interaction between processes is symmetric
-
Servent: act as a client and a server at the
same time -
Overlay network(覆盖网络)
结构化: 分布式哈希DHT
非结构化: Gossip非结构画覆盖网络
从杂乱到收敛，有学习能力的网络，从非结构化进化到结构化（可以由机器学习加速）
-
Nodes such as those maintaining an index or acting as a broker are superpeers(超级节点)
-
Client-superpeer relation can be fixed or dynamic.
