Differences between hubs and vswitches (1)

The appearance of Switch replaces the original HUB.

First, let's first briefly understand the difference between a vswitch and a hub. A hub uses a bandwidth sharing method. For example, a hub is like a one-way street. The "10 m" bandwidth is used by multiple ports. When a port occupies most of the bandwidth, the other port will appear very slow. On the contrary, a vswitch is an exclusive Channel that ensures the bandwidth used by each port, such as a Mbps switch. It ensures that each port has a mbps bandwidth.

Because the vswitch has obvious advantages over the hub, the current hub is almost extinct in the market. The more important factor is that the price of the switch is declining. Driven by the cost-effectiveness, the hub cannot leave the "".

Currently, the network device market has many different names for switches. To a large extent, different brands have different names for switches. I roughly classify switches into several categories: common switch, network management switch, L3 switch, and modular switch.

Common Switch

This is easy to understand, that is, what functions are not available, simply support the data transmission function.

Network Management Switch

This means that devices can be managed and used, such as VLAN division and data traffic restrictions.

L3 Switch

A layer-3 switch is a relatively high-end device, which is not used in general homes or small businesses. A layer-3 Switch has a routing function and is mainly used to connect distributed layer switches.
