> # About Reordering Network Frames

> When you experience a route change in the network, the new selected path may be faster or less congested than the old route.

> If the in-order guarantee feature is enabled, the frames within the network are treated as follows:

> - Frames in the network are delivered in the order in which they are transmitted.
> - Frames that cannot be delivered in order within the network latency drop period are dropped inside the network.
