Hi I hope someone will able to help me out here with some explanation.
My current network is a mix of Linksys wifi AP and Cisco LAN switch.
I am actually doing some speed test.
I am monitoring my wifi connection throughput using Netperc while doing a normal copy and paste file transfer over a the wifi network connection to a LAN device.The speed I am getting is not up to my mark from the netperc monitoring output BUT when I am using a Iperf or Jperf to do further diagnosis the throughput is up to the speed that I am expecting from my network connection. What is the different?Network issue or? Any advise appreciated.
While you are doing file tranfer, many aspects will come into the picture like MTU size, number of fragments and TCP/IP header which will increase the size of your packet.
For example, you are transfering 10 MB of file. This 10MB is then fragmented into say 100 Bytes of each packet.
Now this data when it goes though all the 7 layers of OSI, will add its own headers at each layer. Hence when this 100 Bytes packet is ready to get delievered on physical wire, it size will me more than 100 Byes.
