It seems that in a very large variety of Modem Routers (Wired solutions) or Access point (wireless solutions) there seems to be an option for static and specific limit per user. For example 4Mbps max upload and 10Mbps max upload per user.
However the need here is to have the network device distribute the full range of the available bandwidth to the users. The requirement is that if you have 3 users sharing 30Mbps available from ISP to be able and simultaneously download at 10, 10 and 10 Mbps each, etc. An additional requirement would be to set percentages in that 70% for first and 15% and 15% for the other two would mean that ~21Mbps would be available for first user and the rest of 9 Mbps would be distributed evenly among second and a third user. Note that if the first two users have disconnected then third user is expected to happily enjoy the full speed of 30Mbps
Are there solutions that are offering something similar to the above scenario ? Many thanks
