Achieving zero-copy I/O has long been an important goal in the networking community. However, data serialization obviates the benefits of zero-copy I/O, because it requires the CPU to read, transform, and write message data, resulting in additional memory copies between the real object instances and the contiguous socket buffer. Therefore, we argue for off loading serialization logic to the DMA path via specialized hardware. We propose an initial hardware design for such an accelerator, and give preliminary evidence of its feasibility and expected benefits.
