Abstract: Techniques are provided for managing a user space protocol stack are disclosed herein. A nexus in a kernel space can receive a packet from a packet pool, and extract information from the packet to generate a flow key indicating a particular flow for the packet. The nexus can further look up the flow key in a flow table to determine whether there is an existing flow key stored in the flow table matching the flow key of the packet, and store the packet into a batch of packets of the existing flow when the existing flow key matches the flow key of the packet. When a release condition being met, the nexus can release the batch of packets of the existing flow to a user space protocol stack within a user space application through a channel communicatively coupled to the nexus and the user space protocol stack.

Abstract: The present disclosure describes a portable system for performing business operations. The portable system includes a multi-function device (MFD) including a surface for keeping stationery items, the surface have multiple curved edges for accommodating space constraints, a customizable partition for providing visual privacy to at least one of an official and multiple customers while filling multiple forms and branding, a perforated pattern across at least three sides of the MFD for providing ventilation, a cable management unit for connecting the MFD with a power source, one or more storage units for storing promotional material, a number of filled forms, a product manual, and one or more maintenance records, and a printout interface for providing a point of interaction for customers in order to access one or more printouts. The portable system also includes a user interface for allowing an official or customers to interact with the MFD.
