Abstract: Systems, methods, apparatus and computer-readable medium are described for improving efficiency and robustness for sharing data across different users, agents, processes, drivers, and applications in a system. A shared buffer between multiple entities may be used for sharing data such that the data is only stored once and accessed by multiple entities without copying the data over and over again. An example system may be a network device. For a received packet at a network interface of a network device, the packet may be stored directly in memory. The application or process responsible for accessing and/or manipulating the packet can directly do so by simply using a buffer pointer provided by the buffer manager.
