Comparison Between Layer-2, layer-3, and layer-4 switches (1) layer-2 switches, layer-3 switches, and layer-4 switches: layer-2 switches are relatively mature and belong to data link layer devices, it can identify the MAC address information in the
Let's take a look at the differences between Layer 2 switches, Layer 3 switches, and Layer 4 switches.
(1) Differences Between Layer 2 switches, Layer 3 switches, and Layer 4 switches
The layer-2 switching technology is mature. The layer-2 switch
The layer-2 switching technology is mature. The layer-2 switch is a data link layer device that can identify the MAC address information in the data packet and forward it according to the MAC address, the MAC addresses and corresponding ports are
The two-fork search tree is described earlier, and he has no problem with the efficiency of finding and inserting in most cases, but he is less efficient in the worst case. The data structure of the balanced lookup tree introduced in this article
1) layer-2 Exchange Technology
The layer-2 switching technology is relatively mature. The layer-2 switch is a data link layer device that can identify MAC locations in data packets.Address information, which is forwarded based on the MAC address,
I. Main differences between layer-3 vswitches and vroutersThe most fundamental difference between a layer-3 Switch and a router is that a layer-3 Switch also has a "routing" function, which is consistent with the routing function of a traditional
It is not very difficult to see an algorithm question on the Internet. There are also solutions for searching, but there are usually several layers of for loops. I tried to write it down.
