Systems and methods of classifying data flows being communicated on a network by one or more network elements. One method includes creating a table including information of packet timestamps and pre-defined packet header fields, grouping packets into data flows based on information in the table, assigning flow identifiers to each data flow, determining a plurality of feature/characteristic sets having one or more features and/or one or more characteristics of the data flows, determining one or more classifiers to predict flow labels using the plurality of feature/characteristic sets, and generating a classification policy that includes the one or more classifiers to classify data flows on the network. The method can also include storing the classification policy in at least one non-transitory computer medium that is accessible by a network element that is classifying data flows on the network, and using the classification policy to classify data flows.

Methods and apparatus for low latency operation in user space networking architectures. In one embodiment, an apparatus configured to enable low latency data transfer is disclosed. The exemplary embodiment provides a multiplexer that allocates a fixed portion of network bandwidth for low latency traffic. Low latency traffic is routed without the benefit of general-purpose packet processing. In one embodiment, network extensions for low latency operations are described. Specifically, an agent is described that enables low latency applications to negotiate for low latency access. In one embodiment, mechanisms for providing channel event notifications are described. Channel event notifications enable corrective action/packet processing by the low latency application. In one embodiment, mechanisms for providing interface advisory information are described. Interface advisory information may be provided asynchronously to assist in low latency operation.

A telecommunication network associated with a wireless telecommunication provider can be configured to transmit application data using different quality of service (QoS) specifications. In some configurations, data, other than voice and video data, can be transmitted using VoLTE or ViLTE data streams. According to some examples, network hardware and/or software (e.g., in the core network of a telecommunications network), and/or an application on the UE (smartphone, tablet, etc.) may translate data to be compatible with the VoLTE or ViLTE specifications. The translated data is transmitted from the device to the telecommunications network as a VoLTE or ViLTE packet stream. The converted packets may be identified (e.g., a unique digital signature) so that the corresponding hardware and software in the MSO can identify that a stream of VoLTE or ViLTE packets is to be converted back into the native format of the application before being routed to a destination.

A method and apparatus is disclosed that provides improved techniques and metrics used to improve the Quality of Experience Delivered (QED) for use in Private Enterprise networks. The method and apparatus provides normalized metrics used for assessing all service types for performance. Focus is placed on latent scores and allowing for a range of acceptable operational scores. Observation points are identified and metrics collection is performed at the ingress and egress points for functional/application/node/service levels. Assessment based on packet sizes groups is enabled, rather than as an aggregate for better understanding of the tunability of the application layer for improved service. Burstiness of the traffic is gauged to allow for improved scheduling in the RAN. Individual deployments are adapted to assess G and assess S and V for end-to-end performance management.

The present invention provides according to one of its aspects a method of queueing a data frame in one of a plurality of traffic queues at a communication station for transmission over a communication channel in a communication network comprising a plurality stations and an access point (AP). The method comprising selecting a traffic queue based on at least one of 1) a transmission mode, direct link or uplink, of the data frame, and 2) a transmission mode of the traffic queue; and queueing the data frame in the selected traffic queue. The transmission mode of the traffic queue may be a Multi-User (MU) uplink (UL) mode if a data frame previously stored in the traffic queue has been transmitted, since a predetermined period of time, in a resource unit (RU) provided by the AP within a transmission opportunity granted to the AP on the communication channel. The transmission mode may also be a Single-User (SU) mode.

A quality of service (QoS) class indicator (QCI) structure is provided, wherein the QCI structure is arranged to control communication in a communication network and to classify data flows in the communication network, and wherein the QCI structure comprises: an identifier of a provider of an industry vertical and/or of a service in the communication network; and a QoS parameter set for the provider of the industry vertical and/or of the service. A QoS central controller is configured to manage QoS classes in the communication network according to the QCI structure. Each one of one or more QoS sub-network controllers is arranged to configure devices in a respective sub-network of the communication network according to the QCI structure.

Embodiments of the present invention disclose a network function instance management method, including: receiving a management request for a target network function instance, where the management request for the target network function instance carries an identifier of a target virtualized network function descriptor and an identifier of a first network function instance, and the identifier of the first network function instance is used to determine a connection between the target network function instance and the first network function instance; managing the target network function instance based on the management request for the target network function instance; and establishing the connection between the target network function instance and the first network function instance based on the identifier of the first network function instance. In addition, the embodiments of the present invention further disclose a network function instance management apparatus and device.

The present disclosure is directed to a multi-level resource reservation system that obviates one or more of the problems due to limitations and disadvantages of the related art. The multi-level resource reservation system creates, or modifies existing, peer-to-peer protocol(s) to complete a continuous chain of configured ports to support QoS feature(s), e.g., bound latency and guaranteed jitter, for a data flow that traverses an arbitrary sequence of bridges, routers, and virtual links.

Aspects of the disclosure provide an electronic apparatus and a method for wireless communication. The electronic apparatus can include processing circuitry. The processing circuitry can send one or more packet data unit (PDU) session release requests to a wireless communication network system to request a PDU session release procedure. In an embodiment, a timer is used for the one or more PDU session release requests. The processing circuitry can determine whether a network response is received from the wireless communication network system before the timer expires and whether a number of times that the timer expires reaches a predetermined number of times. The processing circuitry can locally release the PDU session when the network response is not received and the number of times that the timer expires reaches the predefined number of times.
