I would agree only under certain limited situations. Per packet load balancing COULD increase jitter, and if you're running VOIP (or similar protocols) could degrade performance. It could also affect TCP performance (on OSes not SACK enabled) as well. This would only really happen if you're T1's are near capacity (~above 80% or so). Near when queues start causing noticeable delays.
If were talking about 2 identically configured T1's, on the same router, through the same loop provider, connected to one ISP--I highly doubt a situation where packet reordering would arise. It's not impossible, but unlikely as all the circuits would be utilized the same, thus queue delays should be similar across the board.
I've done this on a private network with 4 T1's and never had a problem. We were pushing 100GB database dumps across it and performance did quadruple over the single T1.
Yes, but the original poster was dealing with DS3s connected to different NAPs, which is why the packet out-of-order issue can be significant. Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---
