Hi, everybody, I need to implement a kind of weighted round robin distribution for HTTP ICS-based reverse-proxy. I've found some info about packets distribution but neither about users (sessions) distribution. The difference is that, according to the algorithms, packets can be left in a queue (so load balancing is achieved), while users should not.
The given data is a list of N servers and their relative weights W[n]. Could someone suggest a link for appropriate algorithm? I tried to use the well-known round robin modification of constructing a virtual cicrle, divided into N sectors, each of which is proportional to corresponding server weight. But it may produce very uneven distribution in time, that is for a period it draws a series with some servers probabilities far from their weights, then it begins to draw a series with other servers probabilities far from their weights. I could show an example, but it's not necessary, I think. For a large period the mean values approximate to the weights. But I'd like to have a short time smooth distribution. Thanks in advance. Best wishes, Stanislav Korotky. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
