电路交换和消息交换的区别

先决条件——计算机网络|切换技巧
电路交换和消息交换都是用于将不同设备相互连接的方法。电路交换和消息交换之间的主要区别在于，电路交换是通过在两个系统之间设置物理路径来完成的，而消息交换则采用存储转发方法。

电路切换

消息切换

在消息交换中，数据首先由一个节点存储，然后转发到另一个节点以将数据传输到另一个系统。

电路交换和消息交换的区别：

S.NO	Circuit Switching	Message Switching
1.	Circuit Switching is done by setting a physical path between two systems.	In message Switching, data is first stored by one node then forward to another node to transfer the data to another system.
2.	In circuit switching, data is not stored.	In message Switching, data is first stored, then forwarded to the next node.
3.	Circuit Switching needs a dedicated physical path that’s why the messages need not be addressed.	Message switching does not need a dedicated physical path and on Message switching, The messages are addressed independently.
4.	Circuit Switching is Geographical addressing.	Message Switching is Hierarchical addressing.
5.	Circuit Switching is costlier than message Switching.	The cost of message switching is less than circuit switching.
6.	Circuit switching routing is manual type routing.	Message Switching routing is not manual type routing, here route is selected during call setup.
7.	Circuit switching reserves the full bandwidth in advance. because of that, there is a lot of wastage of bandwidth	Message Switching does not reserve the entire bandwidth in advance. and that’s why bandwidth is used to its maximum extent.
8.	In-circuit switching, the charge depends on time and distance.	In message switching, the charge is based on the number of bytes and distance.
9.	Congestion occurs per minute in circuit switching.	In message switching, no congestion or very little congestion occurs.
10.	Circuit switching uses Analog and digital media on a variety of platforms.	Whereas Message switching uses digital media on a variety of platforms.
11.	In-circuit switching there is no propagation delay.	While In Message switching there is a propagation delay.
12.	The transmission capacity of circuit switching is very low.	while the transmission capacity of message switching is high.
