internet usage 'other'

[#1]

My internet usage consists of web, gaming, streaming and ... 'other' Other constitutes about 10% - what is 'other', or what could it be? I am not the only user.

"other" constitutes traffic which is either:
Not listed above (e.g. isnt web/email/p2p)
OR
its traffic which plusnets traffic management system hasnt recognised. Not necessarily an issue - unless you start seeing slow speeds when you use a certain protocol.
hope that helps
