ascent Posted January 5, 2010 Report Posted January 5, 2010 my server 25 raid 2 patry going raid server upload 1.5Mb/s is this normal?
ProjectX Posted January 6, 2010 Report Posted January 6, 2010 Yup confirmed, 3 raids in instancies and 6Mbit/s upload. It always hapens when a lot of people are in the same place. I think it is something with Raid related ( maybe not, didnt try to do it without raid ).Tried to turn off LoS and Addon Channel and it didnt worked. Dunno why so much data is send to players ...
FragFrog Posted January 6, 2010 Report Posted January 6, 2010 Quite simple: because it increases cubicly with number of players that can see eachother. Elaboration: consider 1 player sends 1kb of data per second to everyone in view - it is a rough estimation, but in my experience a fair one. If there are 2 players, this means 1kb + 1kb. For 3 players, this becomes: 1kb + 1kb (data for player 1 send to player 2 and 3) 1kb + 1kb (data for player 2 send to player 1 and 3) 1kb + 1kb (data for player 3 to players 1 and 2) = 6kb, or to put it differently, 3^2. Consider the following numbers: 10 players: 10^2 = 100kb 15 players: 15^2 = 225kb 20 players: 20^2 = 400kb 25 players: 25^2 = 625kb With two raids of 25 users each you're already looking at 1300kb/s bandwidth - while if you would have 10 raids of 5 people each the number of people is the same but the amount of bandwith would only be 250kb/s! So yes, large concentrations of players will (dramatically) increase the amount of bandwidth needed.
ascent Posted January 7, 2010 Report Posted January 7, 2010 hm.. so big.. arcemu 1,000 player upload 500~800kb/s
FragFrog Posted January 7, 2010 Report Posted January 7, 2010 Keep in mind there are a lot of factors influencing the amount of bandwidth. For example, I used 1kb/s in my explanation because it yields nice round numbers, but if you use a higher level of compression this might easily become a lot less. Likewise, if you lower visibility distance not as many players will be able to see eachother and the bandwidth used is a lot lower as well. If bandwidth is a problem, there are plenty of ways to solve it
