ABSTRACT:
A method, apparatus and computer program product for the express forwarding frames having multiple fragments are presented. A timer (NAV) is maintained at each respective node of a wireless Local Area Network (LAN). At least two fragments of a frame are designated as a Time Sensitive Quality of Service (TSQ) frame fragments to be express forwarded. A duration field of each of the TSQ frame fragments is incremented by a first predetermined time increment (DT0) before the TSQ frame fragments are forwarded. The TSQ frame fragments are transmitted when a last frame fragment is ready to be transmitted. A response is received from the second node wherein non-forwarding neighboring nodes each set their NAV according to a value equal to the duration field of the response. The second node attempts forwarding of the TSQ frame fragments when acknowledgement of receipt of the TSQ frame fragments is complete.
