环形拓扑和网状拓扑的区别

先决条件 – 网络拓扑
网状拓扑：
在Mesh拓扑中，节点完全通过专用链路相互连接，其中信息从节点到节点传播，如果有N个节点，Mesh拓扑中有N(N-1)/2条链路。

环形拓扑：
在环形拓扑中，每个节点都连接到它的左侧和右侧节点，其中信息在一个方向上以环形方式从节点传播到节点。如果存在 n 个节点，则在星形拓扑中也有 n 个链接.在环形拓扑中，要添加新节点，必须断开整个连接。

环形拓扑和网状拓扑的区别：

S.NO	Ring Topology	Mesh Topology
1.	In ring topology, every node is connected to it’s left and right side nodes.	In mesh topology, the nodes are connected to each other completely via dedicated link.
2.	The cost of ring topology is low.	The cost of Mesh topology is expensive.
3.	There are N links in ring topology, if there are N nodes present.	There are N(N-1)/2 links in Mesh topology, if there are N nodes.
4.	In ring topology, the information is travel from nodes to nodes in ring manner in one direction.	In mesh topology, the information is travel from nodes to nodes.
5.	Ring topology is poor extensible.	Mesh topology is also poor extensible.
6.	Ring topology is used in LAN.	Mesh topology is generally suited for WAN.
