The present invention discloses a computer implemented system and method for a no lock, zero data copy message transfer mechanism used in a multi-core processor used in a modem in a telecommunications network. The method includes: for each of a plurality of processing cores, get the kernel to user space mapping (K-U) buffer and the corresponding buffer descriptor, the data packet is inserted into the buffer; and the buffer insertion ring buffer descriptor. The method further includes: create a frame descriptor K-U mapping buffer pointer, the frame is inserted into the frame descriptor queue dynamic PCD rules IP address mapping to the specified frame queue, and create a buffer descriptor from the frame descriptors.
