The systems and methods of the present disclosure are directed towards a dynamic system that is configured to identify and map networked traffic, such as that of video, voice, file transfer, and web based applications to predetermined Quality of Service (QoS) classes. The different QoS classes can be associated with different traffic priorities. The networked traffic can be encrypted, which can prevent an intermediate device from processing or otherwise reading the packet headers of the traffic. The systems and methods of the present disclosure can predict QoS classes for encrypted traffic based on traffic patterns and other characteristics of the encrypted traffic.

Transport packets comprising Universal Serial Bus (USB) packet data are transported over a communications network in a manner adapted to the USB context of the USB data transfers the USB packet data belongs to. A transport packet comprising USB packet data has assigned thereto at least one quality-of-service parameter value that depends on the USB context of the USB data transfer applicable to the USB packet data. A USB-data source device is configured to run a computer program causing it to expose the respective USB contexts of the USB data transfers applicable to USB packet data of the transport packets it outputs. The USB-data source device (or its sink) may inform the network of the relationship between transport packets and USB contexts of USB data transfers. The network may include a node device which discriminates the USB contexts of the USB data transfers applicable to USB packet data in transport packets and maps the transport packets to quality-of-service parameter values based on the discriminated USB contexts.

Embodiments provide a method for transmitting a service stream in a flexible Ethernet and an apparatus. The method includes: obtaining a to-be-transmitted service stream, where the service stream is to be transmitted by using a target virtual connection supported by a physical connection group between a transmit end and a receive end, the physical connection group includes multiple physical connections and supports at least one virtual connection, and the target virtual connection is any one of the at least one virtual connection; determining, from total bandwidth resources of the multiple physical connections and according to timeslot configuration tables used by the multiple physical connections, a timeslot bandwidth resource that belongs to the target virtual connection; and transmitting the service stream to the receive end by using the timeslot bandwidth resource that belongs to the target virtual connection.

A network communication device comprises physical layer (PHY) circuitry configured to transmit and receive radio frequency electrical signals to communicate directly with one or more separate network devices; and medium access control layer (MAC) circuitry. The MAC circuitry is configured to: initiate transmission of a packetized message that includes a neighbor awareness networking (NAN) public action frame; receive a data connection request message from a second network device that includes one or more quality of service (QoS) requirements; initiate transmission of a data connection response message that includes data exchange time window information and channel information; and communicate data device-to-device with the second network device according to the data exchange time window information and channel information.

Methods, systems, and devices are described for providing network access services to mobile users via mobile terminals over a satellite system. In embodiments, dynamic multiplexing of traffic from fixed terminals and mobile users on the same satellite beam can take advantage of statistical multiplexing of large numbers of users and on different usage patterns between fixed terminals and mobile users. In embodiments, quality-of-service (QoS) is controlled for mobile devices at a per-user level. Mobile users may be provisioned on the satellite system according to a set of traffic policies based on their service level agreement (SLA). System resources of the satellite may be allocated to mobile users based on the demand of each mobile user and the set of traffic polices associated with each mobile user, regardless of which mobile terminal is used to access the system.

Systems, methods, and devices are disclosed for providing a quality of service between nodes. A service provider can receive, from a first node of a customer network to an ingress node of a service provider network, packets bound for a second node on the customer network that is remote from the first node. The packets are mapped to a network segment according to a traffic type based on an identifier associated with the packets that identifies the traffic type of the packets. The packets are sent via their mapped network segment to an egress node with connectivity to the second node of the customer network according to a quality of service associated with the traffic type identified by the identifier.

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.

A broadband gateway, which enables communication with a plurality of devices, handles at least one physical layer connection to at least one corresponding network access service provider. The broadband gateway may operate as a home gateway to negotiate with one or more visited gateways, a common authorized service area or domain (ASD) for providing services to the visited gateways. The home gateway may establish one or more corresponding communication links with the visited gateways based on the negotiated common ASD. The home gateway communicates corresponding content for the services to the visited gateways via the established corresponding communication links. The home gateway communicates information about gateway functionalities required for the services to the visited gateways. The visited gateways may port gateway functionalities forwarded by the home gateway, or may perform gateway functionality conversion to support the services, which may be acquired via the home gateway and/or the visited gateways from networks.

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.

A wired/wireless composite communication system and a wired/wireless composite communication method perform control to use wired communication for communication data having high priority and to use wireless communication for communication data having low priority among the types of communication data transmitted and received between communication devices provided within a vehicle. Specifically, the wired/wireless composite communication system and the wired/wireless composite communication method transmit wired communication data and wireless communication data divided on the basis of the priority set for each type of the communication data separately by wired communication and wireless communication, and couple the wired communication data and the wireless communication data separately received on a reception side to each other to reconstruct the communication data.
