Here is my scenario.
There are two branch offices in Germany and here Melbourne in Australia. People in Melbourne are going to connect to Citrix VDI in Germany. The latency from here to Germany is about 330ms which people experience some delays while browsing Internet. Bandwidth is sufficiently fast as they are on fiber (100Mb down/up).
Is there a way to improve this latency problem? I know we cannot change physics of distance but what service ISPs offer for this kind of case?
