Teach you to quickly calculate the PoE switch backplane bandwidth

With the rapid development of network monitoring, PoE switch as a good partner, has also been widespread concern. Whether it is the construction of safe city, or Arcades Hotel video surveillance, can be used in PoE switches. Do network monitoring, people know that the performance of a switch to measure the quality of the two important parameters of the backplane bandwidth and packet forwarding rate, in the actual selection of the PoE switch, how to calculate?

Hong Ruiguangxiang fast PoE switch PS104 as an example:

The calculation formula is: backplane backplane bandwidth bandwidth (Gbps= port x2 port number corresponding to the rate of X / PS104) 1000, a total of 5 ports, each port is 100M, namely the backplane bandwidth = (5x100x2) / 1000=1.0Gbps.

If you are not very clear, I will use fungrichda PS1082T as an example, this is a Gigabit PoE switch, there are 8 Mbps ports and 1 Gigabit ports, backplane bandwidth calculation: backplane bandwidth = (8x100+1x1000) x2 / 1000=3.6Gbps.

Hong Rui many PoE switches can be calculated, in short, the calculation of backplane bandwidth, the number of ports are counted.
