In one embodiment, a system comprises a network interface controller comprising circuitry to determine per-flow analytics information for a plurality of packet flows that are received at the network interface controller and to facilitate differential rate processing of a plurality of packet queues for the plurality of packet flows based on the per-flow analytics information.

The present disclosure provides mechanisms to optimize filter processing. Conventional filter processing techniques involve dividing a batch of received data packets into multiple Access Control Lists (ACLs) per filter group, and thus, cannot leverage of optimal ACL processing of large packet batches using the latest processor instruction sets such as 512 bit wide instructions. The filter processing techniques discussed in the present disclosure, some or all rules for a batch of packets are included in a single ACL look-up by including a filter group identifier (ID) in each rule, and also adding the filter group ID to a field of the packet undergoing the ACL look-up. This avoids false matches while also employing a single ACL look-up for an entire batch of packets, regardless of batch-size. The filter processing techniques can be applied to DOCSIS packet processing pipelines and/or other filtering mechanisms.

A computing device includes an appliance status table to store at least one of reliability and performance data for one or more network functions virtualization (NFV) appliances and one or more legacy network appliances. The computing device includes a load controller to configure an Internet Protocol (IP) filter rule to select a packet for which processing of the packet is to be migrated from a selected one of the one or more legacy network appliances to a selected one of the one or more NFV appliances, and to update the appliance status table with received at least one of reliability and performance data for the one or more legacy network appliances and the one or more NFV appliances. The computing device includes a packet distributor to receive the packet, to select one of the one or more NFV appliances based at least in part on the appliance status table, and to send the packet to the selected NFV appliance. Other embodiments are described herein.

Examples include techniques to monitor control plane (CP) network traffic. Examples include monitoring CP traffic between one or more user equipment (UEs) wirelessly coupled to a network and a virtual network function arranged to process user plane (UP) traffic for an application service provided to the one or more UEs to determine whether at least a portion of the UP traffic needs to be routed to a different VNF for UP processing.

Techniques to monitor control plane network traffic

A service provider (SP) network device or system can enable a WiFi protected access 2 (WPA2) pass-through with a user equipment (UE) and define various partitions between a physical access point (pAP) and a virtual AP (vAP) based on virtual network function(s) (VNFs). The WPA2 pass-through can be an interface connection that passes through a computer premise equipment (CPE) or wireless residential gateway (GW) without modifying the data traffic and also enable different packet sizes, even if the vAP or data VNF at the SP network device is not configured to process the size, by fragmenting and defragmenting at least one of: a packet frame from the UE to the vAP, or from the vAP to the UE based on fragmentation criteria.

Various embodiments are generally directed to techniques for improving the routing of control messages among components of a wireless communications system to control the provision of communications services to endpoint devices within a wireless network. An apparatus may include an interface to the network; a virtual switch to retrieve a device identifier of an endpoint device from a payload of a packet and to select a PCRF component to which to route the packet based on the device identifier, the endpoint device coupled to the network; and the selected PCRF component to grant a data session to the endpoint device based on an indication of a request by the endpoint device for the data session conveyed in the payload, the data session comprising an exchange of data between the endpoint device and the interface device through the network. Other embodiments are described and claimed.

Described herein are devices and techniques for deterministic service chaining between virtual network functions (VNFs). A control device can comprise a wide area network (WAN) interface, at least one local interface, and processing circuitry. The WAN interface can communicate with a plurality of WAN links. The at least one local interface can communicate with VNFs. The processing circuitry configured to: receive performance indicators, identify one of the plurality of devices having a value for a performance indicator that exceeds a threshold for a corresponding key performance indicator, and provide notification of a violation based on the identifying. The performance indicators can include latency and resource usage from the WAN interface and the at least one local interface. Also described are other embodiments.

Methods, systems, and storage media for monitoring service function path are disclosed herein. In an embodiment, a service function chain classifier module may receive a network data packet and applying to it a network packet service control that establishes an ordered chain of network service functions to apply to the network data packet as it traverses a service function path. The service function chain classifier module may incorporate into the network packet service control an indicator to obtain time information relating to application of one or more of the plural service functions to the network data packet. A network service performance module may receive the time information relating to the application of the one or more of the plural service functions to the network data packet and to monitor the time information. Other embodiments may be disclosed or claimed.
