摘要： Technologies for identifying service functions that may be performed in parallel in a service function chain include a computing device for running one or more virtual machines for each of a plurality of service functions based on a preferred service function chain being selected. To identify which service functions may be performed in parallel, the computing device may determine which service functions are not required to be performed on a critical path of the service function chain and/or which service functions are not required to be performed in real-time. Additionally, selecting the preferred service function chain may be based on selection criteria.

摘要： Technologies to monitor and manage platform, device, processor and power characteristics throughout a system utilizing a remote entity such as controller node. By remotely monitoring and managing system operation and performance over time, future system performance requirements may be anticipated, allowing system parameters to be adjusted proactively in a more coordinated way. The controller node may monitor, control and predict traffic flows in the system and provide performance modification instructions to any of the computer nodes and a network switch to better optimize performance. The target systems collaborate with the controller node by respectively monitoring internal resources, such as resource availability and performance requirements to provide necessary resources for optimizing operating parameters of the system. The controller node may collect local system information for one or all of the computer nodes to dynamically steer traffic to a specific set of computers for processing to meet desired performance and power requirements.

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, apparatus, and systems for implementing in Network Interface Controller (NIC) flow switching. Switching operations are effected via hardware-based forwarding mechanisms in apparatus such as NICs in a manner that does not employ use of computer system processor resources and is transparent to operating systems hosted by such computer systems. The forwarding mechanisms are configured to move or copy Media Access Control (MAC) frame data between receive (Rx) and transmit (Tx) queues associated with different NIC ports that may be on the same NIC or separate NICs. The hardware-based switching operations effect forwarding of MAC frames between NIC ports using memory operations, thus reducing external network traffic, internal interconnect traffic, and processor workload associated with packet processing.

摘要： A system for network routing based on resource availability. A network switching element (NSE) may be configured to provide status information to a controller. The controller may be configured to utilize the status information in determining control information that may be provided to the NSE. The NSE may further be configured to assign processing of information flows to processors in the NSE based on the control information. For example, the control information may contain minimum and maximum percent utilization levels for the processors. Information flows may be reassigned to processors that have available processing capacity from processors whose operation is determined not to be in compliance with the minimum and maximum levels. Moreover, inactive processors may be deactivated and alerts may be sent to the controller when the NSE determines that no available processing capacity exists to reassign the flows of processors whose operation is determined to be noncompliant.

摘要： Methods, apparatus and systems for routing information flows in networks based on spanning trees and network switching element resources. One or more controllers are used to assign information flows to network switching elements (NSEs) through use of spanning trees derived from link path costs. NSEs generate status information relating to resources they employ to facilitate information flows that is sent to the controller(s). The status information is used to derive link costs, which are then used to generate spanning trees that support routing between the NSEs without any path loops. Information flows are assigned to the NSEs such that the routing paths for the flows use the links in the spanning tree. The link costs and spanning trees are dynamically computed during ongoing operations, enabling the network routing and flow assignments to be reconfigured in response to dataplane events and changes to the information flow traffic.

摘要： Technologies for performing network analysis of a network include a network analytics node to determine one or more features of network traffic of the network. Each feature includes indexes associated with a link property, a protocol, and a time property. The network analytics node monitors the network traffic of the network based on the one or more features and generates one or more observation vectors. Each observation vector includes a plurality of the one or more features based on the monitored network traffic. The network analytics node performs a statistical network analysis of the network traffic based on the generated one or more observation vectors to generate a probabilistic model of the network traffic.
