Specifies the maximum number of outstanding packets permitted on the system. When the number of outstanding packets reaches this limit, the QoS Packet Scheduler postpones all submissions to network adapters until the number falls below this limit. Specifies the maximum, total percentage of link bandwidth that all QoS-aware applications on this computer can reserve.

If no QoS-aware application reserves any bandwidth, then this setting has no effect and all bandwidth is available for use by other applications. If a QoS-aware application reserves more bandwidth than it uses, then the unused, reserved bandwidth is available for use by other applications.

The reservation does not ensure that the bandwidth will be available to the QoS-aware application because applications that are not QoS-aware might consume too much bandwidth. For example, the default value of the registry entry reserves 80 percent of the bandwidth for QoS-aware applications, but this does not prevent other applications from using more than the remaining 20 percent of the bandwidth.

Determines the smallest unit of time, in microseconds, used by the QoS Packet Scheduler when scheduling packets for transmission. The QoS Packet Scheduler cannot schedule packets for transmission more frequently than permitted by the value of this entry. The following table describes Group Policy settings that are associated with QoS and that set alternative DSCP values for packets that do not conform to the QoS traffic flow specification.

You can use these Group Policy settings to specify alternative Layer-3 DSCP values, which are used by Layer 3 network devices to identify each of five service types. The following table describes Group Policy settings that are associated with QoS and that set alternative Layer-2 priority values. You can use these Group Policy settings to specify alternative Layer-2 priority values, which Layer 2 network devices use to identify each of five service types.

Defines the priority value that the QoS Packet Scheduler inserts into the Layer-2 header of packets that do not conform to the flow specification. Defines the priority value that the QoS Packet Scheduler inserts into the Layer-2 header of packets to request the best effort service type. Defines the priority value that the QoS Packet Scheduler inserts into the Layer-2 header of packets to request the controlled load service type.

Defines the priority value that the QoS Packet Scheduler inserts into the Layer-2 header of packets to request the guaranteed service type. Defines the priority value that the QoS Packet Scheduler inserts into the Layer-2 header of packets to request the network control service type.

Defines the priority value that the QoS Packet Scheduler inserts into the Layer-2 header of packets to request the qualitative service type. Rechercher le serveur DNS le plus rapide. J'en voie qui disent recevoir un film en 10 minutes, moi il me faut 8 jours pour en avoir un!

En P2P peer to peer , il n'y a pas de notion de serveur central. Il y a des chances qu'il y ait quelques centaines de seeders pour un blockbuster dont le DVD est sorti il y a 3 jours. Contribuer Recherche dans le forum Faire un lien. On se reportera avantageusement aux pages : Firefox.

AdBlock Plus. Que peut-on faire d'autre? N'y touchez pas. Ne jamais y toucher. The following Group Policy settings and registry entries are associated with QoS. Each registry setting has a corresponding Group Policy setting. The registry settings appear at four locations in the registry; most of the settings are repeated in three of those locations. The registry structure matches the structure of the Computer Configuration Group Policy settings under Administrative Templates in the Group Policy tool.

Each of the tables in this section describes the Group Policy settings and the registry entries in one of those four locations. Specifies the maximum number of outstanding packets permitted on the system. When the number of outstanding packets reaches this limit, the QoS Packet Scheduler postpones all submissions to network adapters until the number falls below this limit.
