摘要:
Disclosed herein is a method for providing a user with an indication of availability of a service at a user terminal, the user terminal being connected to a gateway via a first communications link, and the gateway being connected to a service provider via a second communications link. The method includes determining a service bandwidth demand, a bandwidth availability, and a service priority; determining a service availability based on the service bandwidth demand, the bandwidth availability, and the service priority; and providing the user with an indication of the service availability.

Methods and apparatus for controlling a communication network (2) to deliver traffic to and/or from an end node (4) are presented. In an example method, a network node (8) receives information indicating a user-controllable selection at the end node (4) to have at least some of the end node (4)'s traffic delivered with a low priority level that is lower than a high priority level. Accordingly, the network node (8) controls the communication network to deliver at least some of the end node (4)'s traffic with said low priority level and awards one or more tokens accordingly. Furthermore, the network node (8) may receive information indicating a user-controllable selection at the end node (4) to have at least some traffic delivered with the high priority level. The network node (8) may accordingly redeem one or more tokens awarded to the end node (4) and controlling the communication network (2) to deliver at least some of the traffic with said high priority level.

Modifying quality of service treatment for data flows A method of transmitting a data flow via a network is disclosed where the network supports transmission of data in accordance with a plurality of Quality of Service, QoS, models. Prior to transmission of the data flow, a client system configures a first class of service for the data flow based on a first QoS model, and a first portion of the data flow is transmitted through the network in accordance with the first class of service. In response to detecting a renegotiation condition, the network communicates with the client system to configure a second class of service for the data flow based on a second QoS model, and a subsequent portion of the data flow is transmitted through the network using the second class of service.

One embodiment provides a system that facilitates bandwidth-profile enforcement. During operation, the system indicates a packet's compliance with a bandwidth profile based at least on available high-compliance tokens and medium-compliance tokens. The system further accounts for overflow tokens from a respective class of service (CoS) and distribute an overflow token to another CoS priority level based on the overflow token's CoS information.

A network system, a network control method, and a control apparatus are provided that can easily achieve assurance of the quality of a network service and optimization of the throughput of an entire system. A network control apparatus (11) controls a network having a multi-layer structure, sets a first layer path that provides virtual network functions for a network service on a first layer, monitors whether or not the network service on the first layer fulfills a required service level, and depending on a result of the monitoring, changes a setting of a packet header so that the first layer path will be switched at an end point of the network service. This causes a resource on a second layer, which is a lower layer than the first layer, to change.

Methods and computing systems for allocating an information rate to a particular traffic type of a plurality of traffic types of egress traffic is described. A state of the particular traffic type for a particular time slot of a current time period is determined. This includes determining the information rate such that a loss probability threshold is not exceeded, based on historical data of the particular traffic type. The historical data includes a plurality of observed throughput rates of the particular traffic type during a plurality of previous time periods at which the particular traffic type experienced the state of the particular traffic type. The information rate (e.g., a committed information rate) is allocated to the particular traffic type for the particular time slot.
摘要:
A machine includes a processor and a memory connected to the processor. The memory stores instructions executed by the processor to preserve a second level domain, track requests for subdomains of the second level domain, determine the size of encoded subdomain data and determine the size of response data for subdomain requests. When the ratio of the number of unique subdomains versus the number of subdomain requests is over a first threshold a first satisfied condition is established. It is determined, in response to the first satisfied condition, when the size of the subdomain data exceeds a second threshold and the size of response data exceeds a third threshold to establish a second satisfied condition corresponding to deemed domain name system tunnel activity. It is determined, in response to the first satisfied condition, when the size of the subdomain data exceeds the second threshold to establish a third satisfied condition corresponding to deemed domain name system data exfiltration activity.
摘要:
The present invention provides a method, an apparatus, and a system for controlling services, where the method includes: receiving, by a PCRF, congestion state information on a cell, resource-related information on the cell, and subscriber-related information on a UE in an activated state in the cell that are sent by an access network device; generating, by the PCRF, a QoS policy and/or a charging policy for the UE in the activated state in the cell according to the congestion state information on the cell, the resource-related information on the cell, and the subscriber-related information on the UE in the activated state in the cell; sending, by the PCRF, the generated QoS policy and/or charging policy to a PCEF, so as to enable the PCEF to execute the QoS policy and/or the charging policy.
