Data link frame reordering
Datalink frames or networking packets contain protocol information in the header and optionally in the trailer of a frame or a packet. We are proposing a method in which part of or all of the protocol information corresponding to a frame or a packet is transmitted separately in another datalink frame. The “Separately Transmitted Protocol Information” is referred to as STPI. The STPI contains enough protocol information to identify the next hop node or port. STPI can be used avoid network congestion and improve link efficiency. Preferably, there will be one datalink frame or network packet corresponding to each STPI, containing the data and the rest of the protocol information and this frame/packet is referred to as DFoNP. The creation of STPI and DFoNP is done by the originator of the frame or packet such as an operating system. |
