Abstract:
Power consumption levels of a network device can be adjusted based upon traffic flow at the device. A network device can recognize a situation where the traffic flow associated with a CPE device reaches a level that can be supported by a smaller channel set, and when this situation arises, the CPE device can request and receive an updated, smaller channel set. In response to receiving the smaller channel set, the CPE device can operate using fewer resources, thereby reducing power consumption at the CPE device. When traffic level at the CPE device warrants, the CPE device can request and receive a new or updated, larger channel set.
Abstract:
Systems and methods for bandwidth allocation and estimation are disclosed. A computer communicates via multiple active streams, each having a type. The computer determines whether to enable or disable bandwidth management. Upon determining to enable bandwidth management, the computer estimating a total available bandwidth, determines, for each stream, a requested bandwidth, and dynamically allocates a portion of the total available bandwidth among the active streams. Upon determining to disable bandwidth management, the computer foregoes dynamically allocating bandwidth among the streams.
Abstract:
Systems, methods and apparatus for quality of service (QoS) flows in a communication system are provided. In one aspect a method is providing for establishing a QoS flow for an application in a user equipment device. The method includes receiving QoS information from one of an application and a network. The method further includes establishing a QoS communication flow for the application based on the received information. The method also includes receiving QoS information from the other of the application and the network and modifying the established QoS communication flow based on the additional information.
Abstract:
A change in user interest level of a user application of a client device in communication with a network infrastructure at a first quality of service level is assessed (306). In response, the quality of service associated with the user application is dynamically changed (308) to a second quality of service level, while keeping the user application active, based, at least in part, on the change in user interest level of the user application.
Abstract:
Die Erfindung betrifft ein Verfahren zur Gewährleistung von Dienstgüte in paketvermittelnden Mobilfunknetzen. Erfindungsgemäß benutzen das Funkzugangsnetz RAN und das Kernnetz CN die Dienstgüteinformationen unabhängig voneinander und ohne Signalisierung einzelner Parameter, um die der Dienstgüte entsprechende Übertragung von Paketen im Uplink und Downlink sicher zu stellen. Dies erfolgt ausschließlich anhand von für die einzelnen TCLs konfigurierten lokalen Einstellungen. Dadurch wird eine einschneidende Reduzierung der Komplexität gegenüber dem heute üblichen Verfahren erreicht. Weitere Vereinfachungen ergeben sich durch die hier dargestellte Verknüpfung verschiedener Aufgaben miteinander oder mit bereits bestehender Datenübertragung.
Abstract:
A WIMAX dynamic QoS realizing method. The method includes: media gateway senses the service type of user requested, and notifies user station establishing connection with base station. The user station sends establishing connection request to the base station, and requests assigning bandwidth, establishing service channel from media gateway to the user station and the base station. The realizing dynamic QoS method of the present invention doesn't need reserve bandwidth, can sense service by media gateway MG, and requests assigning bandwidth according to service's need. Accordingly, the method improves the air bandwidth capacity factor, and reduces SS realizing complexity and cost, convenient for WIMAX device mutual communication, and improves service processing efficiency.
Abstract:
Systems and methods for preemption of Traffic Engineering LSPs such that preemption decisions are made in a coordinated fashion along the path of a new LSP and computation of a new path for a preempted LSP can take advantage of knowledge of newly unavailable links. The efficiency of the preemption mechanism is greatly increased and the undesirable effects of heterogeneous preemption decisions are limited. The amount of signaling may also be significantly reduced. In one implementation, these advantages are achieved by exploiting an upstream preemption feedback mechanism that uses an incremental timer to delay preemption decisions until feedback is available.
Abstract:
A resource control system and method for reorganizing resource allocation and adaptively controlling the resources in the communication network are disclosed. In the system or method proposed by the present invention, a resource processor (CN-RP) in the communication network, upon receiving a resource request message (ResReq) from a resource processor (CS-RP) such as a mobile terminal in step (205), determines the feasibility of the resource allocation in step (210). In case that the resource allocation is feasible, CN-RP reorganizes resources in consideration of resource allocation about other communication sessions in step (215), and offers the resource calculated by reorganization to CS-RP in step (220). CS-RP determines the acceptability of this offered resource allocation in step (225). If this offered resource allocation is acceptable, CS-RP sends a resource acceptance message (Res Acc) in step (230), and accommodates the resources.
Abstract:
A multiservice IP network and a method are described herein that use an enhanced QOS message which makes it possible for an IP router to reserve resources for and admit a high priority traffic flow without needing to terminate an existing low priority traffic flow. In accordance with the present invention, in the event an emergency reservation request arrives at an IP router and there are not enough resources to support the high priority traffic flow, then the IP router reduces the reservation of one or more low priority traffic flows to a reduced level. The IP router also sends a notification message to the sender indicating that the reservations have been reduced. Thereafter, the high priority traffic flow can be admitted. As such, if there is enough adaptive traffic in the multiservice IP network, then the low priority calls need not be terminated instead only the resources are reduced to a lower but still acceptable QoS level. And, when traffic conditions improve the reduced reservations can be increased back to the original level.
Abstract:
Methods and systems are directed to managing a protocol network failure in a network clustering system. A cluster master and each client member in the cluster are configured to determine a primary protocol network, a secondary protocol network, and the like, for exchanging a cluster protocol message. Each client member in the cluster determines its `active protocol network' from at Ieast the primary protocol network, and the secondary protocol network when it joins the cluster. Each client member tests its connectivity to the cluster master through the primary protocol network. If a client member detects a failure on the primary protocol network, it dynamically fails over to the secondary protocol network, or the like, without leaving the cluster. If connectivity to the primary protocol network is restored, the client member dynamically resumes the protocol message exchange on the primary protocol network without leaving the cluster.
