With the increase of the number of nodes, the data flow of a port in the network increases, which is easy to cause bottlenecks.
2. Addressing table
With the increase of the number of nodes, the mac table of the switch and the routing table of the router will increase rapidly. In addition, if the appropriate addressing strategy (especially the choice of router routing protocol) is not adopted, the resources of a large number of network nodes will be occupied when looking up the list, resulting in the overall performance degradation.
3. Utilization rate of network nodes
With the increase of the number of nodes, the network node equipment will be frequently accessed (internal and external), and the equipment load will also increase with the increase of the number of nodes, thus affecting the overall performance of the network.
4. Other reasons
1) Due to the backward internal software version, the adaptability to the increased network scale is getting worse and worse, which will affect the network performance.
2) The aging and backwardness of equipment will affect its ability to handle the increased network-scale data.
3) The network nodes are complex, and the attacks of viruses and hackers will cause performance degradation.
This friend, brother, I tried my best to answer your question. It's purely personal. I hope you can get an authoritative answer or wait for someone else's answer, but this is my own original work. I hope I can help you. Look at this webpage. I found it on Zhihu. You can also have a look. There is some truth in this, just add it.
