Correct! 
 So Gateway B will process double of the traffic than gateway A.

Renzo, 
 1:2 means that Gateway ! will process 33% of the traffic while 66% of the traffic is processed by gateway 2. 
 If both gateway have 1, ttraffic will be load balanced.

In my opinion it should be like this: 
 
 w1 = weight link 1 
 w2 = weight link 2 
 pt = proportional traffic percentage 
 pt1 = traffic percentage link 1 
 pt2 = traffic percentage link 2 
 
 for first i calculate the proportional traffic percentage: 
 
 pt = 100 / ( w1 + w2 ) 
 
 and after this I can calculate the singular percentage for the 2 links: 
 
 pt1 = w1 x pt 
 pt2 = w2 x pt

example: 
 
 w1 = 1 
 w2 = 2 
 
 => pt = 100 / (1+2) = 100/3 = 33,3 
 
 => pt1 = 1 x 33,3 => 33% 
 
 => pt2 = 2 x 33,3 => 66%

modifying the weight we can modify the percentages. 
 for more than 2 links we can sum the weight of all the links inside the formula pt = 100 / ( w1 + w2 + ... + wn). 
 
 Best regards.

Hi Renzo_Snia, 
 That is exactly how the weight is calculated. But the traffic is routed to the gateway as per the number of sessions and not the data from each session. 
 e.g. 
 Session 1 is media streaming:200MB data used 
 Session 2 is website browsing :150KB date used 
 Session 3 is a FTP connection. : 200KB data used 
 If the weight between 2 gateway is 2 and 1 respectively to GW1 and GW2, then Session 1 and Session 2 would go through GW1 and Session 3 will go through GW2 .
