Suppose you have 2 "pipes": Round Robin: 1 packet to pipe1 1 packet to pipe2 1 packet to pipe1 1 packet to pipe2 Weighted round Robin, weighted 2 to 1: 1 packet to pipe1 1 packet to pipe1 1 packet to pipe2 1 packet to pipe1 1 packet to pipe1 1 packet to pipe2 "Per session" balancing may be useful when you have paths that are not very "equal". If you load balance to different ISPs packets could arrive out of order (in fact they are likely to). This is not really a problem for modern TCP stacks. Session balancing, if done properly, should guarantee that the ACKs for a download go out the same pipe as the data is arriving. Its not clear from the datasheet if thats the case, but thats the correct way to do it. Its seems like a quite comprehensive product to me, from the docs. Ted's analysis is backwards. "load balancing" is a vague term. "Weighted Round Robin" is a more specific term for how they have implemented the load balancing. Danial __________________________________________ Yahoo!
