Abstract: An apparatus, a method, and a computer program for generating data packets according to a transport protocol from an application buffer comprising a plurality of data streams is provided. The apparatus comprises an input circuit configured to receive metadata comprising at least one of information about data packet types supported by the transport protocol, information about an offset and a length of the supported data packet types, and information about possible stream header start positions, possible payload start positions and possible offsets in the data streams. Further, the apparatus comprises a parsing circuit configured to identify offsets in an application buffer as possible segmentation points based on the metadata, to segment the application buffer at the possible segmentation points into segments for data packets, and to generate data packets according to the transport protocol based on the segments. Furthermore, an apparatus, a method and a computer program for processing the application buffer is provided.

Abstract: Embodiments include a method of opening a Quick User Datagram Protocol (UDP) Internet Connections (QUIC) socket on a computing platform, initializing QUIC packet processing of a hardware-based offloader, opening a QUIC connection to the offloader, and transmitting a first QUIC packet to the offloader over the QUIC connection. The hardware-based offloader encrypts and transmits the QUIC packet.

Abstract: Tenant support is provided in a multi-tenant configuration in a data center by a Physical Function driver communicating a virtual User Priority to a virtual traffic class mapper to a Virtual Function driver. The Physical Function driver configures the Network Interface Controller to map virtual User Priorities to Physical User Priorities and to enforce the Virtual Function's limited access to Traffic Classes. Data Center Bridging features assigned to the physical network interface controller are hidden by virtualizing user priorities and traffic classes. A virtual Data Center Bridging configuration is enabled for a Virtual Function, to provide access to the user priorities and traffic classes that are not visible to the Virtual Function that the Virtual Function may need.

Abstract: Examples may include a method of protecting memory and I/O transactions. The method includes allocating memory for an application, assigning a resource of a physical device to the application, assigning a process address space identifier to the assigned resource, creating a security enclave to protect the allocated memory of the application, and associating the security enclave with the process address space identifier to protect the allocated memory and the assigned resource.

Abstract: Examples described herein identify a flow that is considered heavy or high in transmit or receive rate. A filter rule can be assigned to the flow such that packets of the heavy flow are allocated to a queue and core for processing. Various queues and cores can be dedicated to processing received or transmitted packets of heavy flows and various queues and cores can be dedicated to process received or transmitted packets of non-heavy flows. An application acceleration layer can be used to migrate an application to a core that is to process received or transmitted packets of a heavy flow.

Abstract: Examples may include a computing platform having a host driver to get a packet descriptor of a received packet stored in a receive queue and to modify the packet descriptor from a first format to a second format. The computing platform also includes a guest virtual machine including a guest driver coupled to the host driver, the guest driver to receive the modified packet descriptor and to read a packet buffer stored in the receive queue using the modified packet descriptor, the packet buffer corresponding to the packet descriptor.
