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.

Buffer manager

A framework that creates an abstraction layer to configure/display system resources and process/application resource utilization while accessing the system information from a CLI. The framework is implemented using a scripting language like python and uses pre-existing OS or OEM tools to configure/display system resource information and filter the output to implement the CLI. A user argument defines the choice to use the framework as a standalone utility (running in a Linux shell) or in a library mode. Since the framework makes use of OS or OEM tools and does not access any system resource directly, the framework can be run in the virtual machine and baremetal OS. The framework can access the OS or OEM tools to configure/display system resource information locally and remotely by establishing remote communication through rsh (remote shell) connections. This approach allows reuse of the code, minimizes the implementation complexity, reduces development time and minimizes defects.
