for a better understanding let’s take a real example:
1. when i request a web site —–> one UL TBF is established
2. the browser does not diplay the whole web page of the requested site ——–> the first DL TBF is established
3.Web page doesn’t show all its images, so i Refresh it ——> another UL TBF is established
4. After refresh, browser displays missing image ——–> is this case, the MFS will establish another DL TBF to send the missing part of the web page?? or it will use the first established DL TBF?????
I appreciate ur reply
