摘要： Methods and apparatus for accelerating VM-to-VM Network Traffic using CPU cache. A virtual queue manager (VQM) manages data that is to be kept in VM-VM shared data buffers in CPU cache. The VQM stores a list of VM-VM allow entries identifying data transfers between VMs that may use VM-VM cache “fast-path” forwarding. Packets are sent from VMs to the VQM for forwarding to destination VMs. Indicia in the packets (e.g., in a tag or header) is inspected to determine whether a packet is to be forwarded via a VM-VM cache fast path or be forwarded via a virtual switch. The VQM determines the VM data already in the CPU cache domain while concurrently coordinating with the data to and from the external shared memory, and also ensures data coherency between data kept in cache and that which is kept in shared memory.

摘要： Methods and Apparatus for Multi-Stage VM Virtual Network Function and Virtual Service Function Chain Acceleration for NFV and needs-based hardware acceleration. Compute platform hosting virtualized environments including virtual machines (VMs) running service applications performing network function virtualization (NFV) employ Field Programmable Gate Array (FPGA) to provide a hardware-based fast path for performing VM-to-VM and NFV-to-NFV transfers. The FPGAs, along with associated configuration data are also configured to support dynamic assignment and performance of hardware-acceleration to offload processing tasks from processors in virtualized environments, such as cloud data centers and the like.

摘要： Technologies for simulating service degradation in telemetry data include a simulator device. The simulator device is to identify a telemetry data stream from a production system to a first management system. The simulator device is also to fork a copy of the telemetry data stream for transmission to a second management system, determine perturbations associated with a determined service degradation type, and apply the perturbations to the forked telemetry data stream. Other embodiments are also described and claimed.

摘要： Various approaches for the deployment and coordination of terrestrial cellular (e.g., 5G) network exclusion or mitigation zone, for the dynamic deployment of radio frequency blocking for in-motion aerial devices are described. Approaches are also described for a space-based non-terrestrial network exclusion or mitigation zone, including for maintenance or multi-constellation/multi-orbit coordination. The calculation, distribution, deployment and use of exclusion and inclusion zones are described for coordination with such a terrestrial cellular network or non-terrestrial satellite network.

摘要： Various approaches for the deployment and coordination of inter-satellite communication pathways, defined for use with a satellite non-terrestrial network, are discussed. Among other examples, such inter-satellite communication pathways may be identified, reserved, allocated, and used for ultra-low-latency communication purposes.

摘要： Methods for frequency scaling for per-core accelerator assignments and associated apparatus. A processor includes a CPU (central processing unit) having multiple cores that can be selectively configured to support frequency scaling and instruction extensions. Under this approach, some cores can be configured to support a selective set of AVX instructions (such as AVX3/5G-ISA instructions) and/or AMX instructions, while other cores are configured to not support these AVX/AMX instructions. In one aspect, the selective AVX/AMX instructions are implemented in one or more ISA extension units that are separate from the main processor core (or otherwise comprises a separate block of circuitry in a processor core) that can be selectively enabled or disabled. This enables cores having the separate unit(s) disabled to consume less power and/or operate at higher frequencies, while supporting the selective AVX/AMX instructions using other cores. These capabilities enhance performance and provides flexibility to handle a variety of applications requiring use of advanced AVX/AMX instructions to support accelerated workloads.

摘要： Various approaches for detecting and mitigating interference in a supplemental coverage from space (SCS) networking arrangement are disclosed, using an SCS zone for a geographic area in connection with exclusion, coordination, or inclusion of SCS communications in the geographic area. In an example, an approach for dynamically mitigating interference includes: obtaining orbital position data for at least one satellite vehicle (e.g., low-earth orbit (LEO) SV), which can perform SCS network communications to a geographic area that includes a terrestrial network (e.g., 5G network); determining operational parameters to mitigate terrestrial interference of the SCS network communications in the geographic area, with the geographic area identified based on the orbital position data; and modifying operation of the SCS network communications in the geographic area, based on the determined operational parameters.

摘要： Various approaches for the verification of 5G networks, including the use of fingerprint-based IQ measurements for authentication and integrity monitoring, are discussed. In an example, a method of using fingerprints for authentication of network use includes: capturing in-phase and quadrature (IQ) data from a network connection between a user equipment (UE) and a 5G network; performing authentication of the network connection between the UE and the 5G network, by using a symbol of the IQ data as a random factor for the authentication; and monitoring the IQ data on an ongoing basis to verify the network connection between the UE and the 5G network. The method may also include creating a baseline IQ measurement from the IQ data when performing the authentication between the UE and the 5G network, and monitoring the IQ data by using a comparison of an ongoing IQ measurement to the baseline IQ measurement.

摘要： Various approaches for the packet processing, and the use of templates for generating modification commands for packet processing, are discussed herein. In an example, operations performed by network packet processing circuitry include: obtaining a stream of packets; obtaining a packet modification template that provides at least one command to insert content within the packets and change the packets according to an output format of a network protocol; receiving parameters to modify the packet modification template; and applying the packet modification template to modify the packets. In further examples, application of the packet modification template is performed using multiple processing components arranged in parallel groups of serial pipelines, each of the serial pipelines applying a portion of the packet modification template within at least a first stage and a second stage in each of the serial pipelines.
