Technologies for dynamically managing a batch size of packets include a network device. The network device is to receive, into a queue, packets from a remote node to be processed by the network device, determine a throughput provided by the network device while the packets are processed, determine whether the determined throughput satisfies a predefined condition, and adjust a batch size of packets in response to a determination that the determined throughput satisfies a predefined condition. The batch size is indicative of a threshold number of queued packets required to be present in the queue before the queued packets in the queue can be processed by the network device.

An apparatus and method for closed loop dynamic resource allocation. For example, one embodiment of a method comprises: collecting data related to usage of a plurality of resources by a plurality of workloads over one or more time periods, the workloads including priority workloads associated with one or more guaranteed performance levels and best effort workloads not associated with guaranteed performance levels; analyzing the data to identify resource reallocations from one or more of the priority workloads to one or more of the best effort workloads in one or more subsequent time periods while still maintaining the guaranteed performance levels; reallocating the resources from the priority workloads to the best effort workloads for the subsequent time periods; monitoring execution of the priority workloads with respect to the guaranteed performance level during the subsequent time periods; and preemptively reallocating resources from the best effort workloads to the priority workloads during the subsequent time periods to ensure compliance with the guaranteed performance level and responsive to detecting that the guaranteed performance level is in danger of being breached.

Apparatus and method for a closed-loop dynamic resource allocation control framework

In some examples, for process-to-process communication, such as in function linking, a virtual channel can be provisioned to provide virtual machine to virtual machine communications. In response to a transmit request from a source virtual machine, the virtual channel can cause a data copy from a source buffer associated with the source virtual machine without decryption or encryption. The virtual channel provisions a key identifier for the copied data. The destination virtual machine can receive an indication data is available and can cause the data to be decrypted using a key accessed using the key identifier and source address of the copied data. In addition, the data can be encrypted using a second, different key for storage in a destination buffer associated with the destination virtual machine. In some examples, the key identifier and source address is managed by the virtual channel and is not visible to virtual machine or hypervisor.

Process-to-process secure data movement in network functions virtualization infrastructures

In the present disclosure, functions associated with the central office of an evolved packet core network are co-located onto a computer platform or sub-components through virtualized function instances. This reduces and/or eliminates the physical interfaces between equipment and permits functional operation of the evolved packet core to occur at a network edge.

Apparatus, methods, and systems for tuple space search-based flow classification using cuckoo hash tables and unmasked packet headers are described herein. A device can communicate with one or more hardware switches. The device can include memory to store hash table entries of a hash table. The device can include processing circuitry to perform a hash lookup in the hash table. The lookup can be based on an unmasked key include in a packet header corresponding to a received data packet. The processing circuitry can retrieve an index pointing to a sub-table, the sub-table including a set of rules for handling the data packet. Other embodiments are also described.

Flow classification apparatus, methods, and systems

A computer-implemented method can include receiving a queue depth for a receive queue of a network interface controller (NIC), determining whether a power state of a central processing unit (CPU) core mapped to the receive queue should be adjusted based on the queue depth, and adjusting the power state of the CPU core responsive to a determination that the power state of the CPU core should be adjusted.

Using network interface controller (NIC) queue depth for power state management

The present invention relates to platform power management.

Platform and processor power management

Examples described herein relates to a network interface apparatus that includes packet processing circuitry and a bus interface. In some examples, the packet processing circuitry to: process a received packet that includes data, a request to perform a write operation to write the data to a cache, and an indicator that the data is to be durable and based at least on the received packet including the request and the indicator, cause the data to be written to the cache and non-volatile memory. In some examples, the packet processing circuitry is to issue a command to an input output (IO) controller to cause the IO controller to write the data to the cache and the non-volatile memory. In some examples, the cache comprises one or more of: a level-0 (L0), level-1 (L1), level-2 (L2), or last level cache (LLC) and the non-volatile memory comprises one or more of: volatile memory that is part of an Asynchronous DRAM Refresh (ADR) domain, persistent memory, battery-backed memory, or memory device whose state is determinate even if power is interrupted to the memory device. In some examples, based on receipt of a second received packet that includes a request to persist data, the packet processing circuitry is to request that data stored in a memory buffer be copied to the non-volatile memory.

Data consistency and durability over distributed persistent memory systems

A central processing unit can offload table lookup or tree traversal to an offload engine. The offload engine can provide hardware accelerated operations such as instruction queueing, bit masking, hashing functions, data comparisons, a results queue, and a progress tracking. The offload engine can be associated with a last level cache. In the case of a hash table lookup, the offload engine can apply a hashing function to a key to generate a signature, apply a comparator to compare signatures against the generated signature, retrieve a key associated with the signature, and apply the comparator to compare the key against the retrieved key. Accordingly, a data pointer associated with the key can be provided in the result queue. Acceleration of operations in tree traversal and tuple search can also occur.

Offload of data lookup operations

One embodiment provides a network system. The network system includes an application layer to execute one or more networking applications to generate or receive data packets having flow identification (ID) information; and a packet processing layer having profiling circuitry to generate a sketch table indicative of packet flow count data; the sketch table having a plurality of buckets, each bucket includes a first section including a plurality of data fields, each data field of the first section to store flow ID and packet count data, each bucket also having a second section having a plurality of data fields, each data field of the second section to store packet count data.

Sketch table for traffic profiling and measurement
