queing vs load balancing

Which is the first thing of queueing and load balancing?

I've experienced load unbalance in 2*512K serial interfaces which are configured as load sharing per packet and cbwfq. If load balancing is after the queueing, load must be equally shared.

Load balancing comes before queueing.

Re: queing vs load balancing

Hi,

Plz be clear about load balancing and queueing. Load balancing occurs when you have multiple links to the same site whereas **Queueing is triggered** only when the packet input rate is higher than the packet output rate. This happens if your processor is overloaded and there is very less memory to handle incoming packets.

Queueing different classes of traffic under CBWFQ is *NOT* load balancing. Your outbound traffic from both the routers simply depends on how much and what type of traffic was inbound to each of the routers. Hence a lot depends on how you have configured load balancing and the CBWFQ classes.

Let me know if you need more info.

Regards,

Naveen.
