  • QoS for latency-sensitive network-traffic flows
    Patent number: 11044194
    Abstract: A telecommunication system can include routing devices, a Quality of Service (QoS) controller, a policy-management device, and a flow-management device. The QoS controller or flow-management device can receive a request from a terminal to create a specialized flow (SF), e.g., for a non-audio, non-video media type. If the request is associated with an authorized user, a setup message can be sent comprising a QoS indicator. The system can create the SF permitting data exchange between the terminal and a routing device. The SF can have QoS characteristics associated with the QoS indicator. In some examples, the terminal can receive network-address information, determine an associated network resource, and send a flow-request message indicating a non-audio, non-video media type. The terminal can then exchange data on the network port with a peer network terminal.
