Question: How can a university network disable intra-network music sharing (ie: itunes)?

[xxxxxxcoolx]

Hi, my university campus has modified its wireless internet network recently and since then students connected to the network can no longer share their music library on iTunes. What are the possible changes they have made to the network that resulted in this ? I am writing a newspaper article about this issue so if anyone has any clue as to how they can disable music sharing on campus, please let me know. Thank you!!

itunes sends out a special signal that can be picked up by others through the internet. Your university campus probably used a firewall to block that signal. It's kinda like how school block 18+ sites. the computer sends out a signal requesting for data transfer and the firewall declines the computer or blocks the response from the site
