Specifies an alternate Layer-3 Differentiated Services Code Point (DSCP) value for packets with the Qualitative service type (ServiceTypeQualitative). The Packet Scheduler inserts the corresponding DSCP value in the IP header of the packets. This setting applies only to packets that do not conform to the flow specification.

Important: If the DSCP value for this service type is specified in the registry for a particular network adapter, this setting is ignored when configuring that network adapter. DSCP value of conforming packets DSCP value of non-conforming packets Limit outstanding packets Specifies the maximum number of outstanding packets permitted on the system. When the number of outstanding packets reaches this limit, the Packet Scheduler postpones all submissions to network adapters until the number falls below this limit. "Outstanding packets" are packets that the Packet Scheduler has submitted to a network adapter for transmission, but which have not yet been sent. If you enable this setting, you can limit the number of outstanding packets. If you disable this setting or do not configure it, then the setting has no effect on the system. Important: If the maximum number of outstanding packets is specified in the registry for a particular network adapter, this setting is ignored when configuring that network adapter. Limit reservable bandwidth Determines the percentage of connection bandwidth that the system can reserve. This value limits the combined bandwidth reservations of all programs running on the system. By default, the Packet Scheduler limits the system to 80 percent of the bandwidth of a connection, but you can use this setting to override the default. If you enable this setting, you can use the "Bandwidth limit" box to adjust the amount of bandwidth the system can reserve. If you disable this setting or do not configure it, the system uses the default value of 80 percent of the connection. Important: If a bandwidth limit is set for a particular network adapter in the registry, this setting is ignored when configuring that network adapter.

The Packet Scheduler cannot schedule packets for transmission more frequently than permitted by the value of this entry. If you enable this setting, you can override the default timer resolution established for the system, usually units of 10 microseconds. If you disable this setting or do not configure it, the setting has no effect on the system. Important: If a timer resolution is specified in the registry for a particular network adapter, then this setting is ignored when configuring that network adapter.
