ABSTRACT:
A device may include logic configured to receive a data unit intended for a destination device and to obtain information from the data unit. The logic may be configured to identify a window using the obtained information, where the window has a range determined by a lower boundary and an upper boundary. The logic may be configured to forward the data unit to the destination device when a portion of the data unit information is within the window.
