交换机和网关之间的区别

先决条件–网络设备

1.开关：
交换机是一个带缓冲器的多端口网桥，其设计可以提高其效率和性能。它是一个数据链路层设备。交换机可以在转发数据之前执行错误检查，这使得它非常高效，因为它不会转发有错误的数据包，而仅将正确的数据包转发到正确的端口。换句话说，交换机划分主机的冲突域。

2.网关：
网关是将两个网络连接在一起的通道，可以在不同的网络模型上工作。它基本上是系统之间的信使代理，从一个系统获取数据，解释数据并将其传输到另一个系统。它也称为协议转换器。它可以在任何网络层上运行。它比开关更复杂。

交换机和网关之间的区别：

SWITCH	GATEWAY
It works as multi-port bridge between networks.	It works as a passage between two networks.
It works in data link layer.	It works in all networks layers.
It performs error checking before forwarding packets.	It does not perform error checking.
It does not work as protocol converter.	While it works as protocol converter.
Packet filtering is provided in switch.	Packet filtering is not provided in gateway.
It is less complex.	It is more complex than switch.
It connects devices that work on same network model.	It connects two networks working on different models.
The format of packet is not changed.	Packet format is changed.
