www.BlackViper.com: Windows XP Service Pack 2 Services 411 - QoS RSVP

QoS RSVP

Default Description:

Provides network signaling and local traffic control setup functionality for QoS-aware programs and control applets.

Additional Information:

Provides traffic control on a network using IPSEC and applications that support QoS, and have an adapter that supports it. The QoS Packet Driver installs by default on any TCP/IP connections. I recommend uninstalling it if it is not needed on your network. As far as I can tell, you also need an ACS Server (Provided with Windows 2000 Server and Advanced Server) for the QoS Packet Scheduler and Applications to request the needed bandwidth. Since my network is not straining under any load, this is rather pointless. You may require this service to be placed on Automatic if you use Windows Media Player or NetMeeting.

Take note: Some people (as I did before I completed extensive research on this) reported that QoS uses 20% of your bandwidth and does not allow any activity, regardless. This is false. For more information, please view this KB article from Microsoft (I normally do not post links to them, but this warrants it):

http://support.microsoft.com/default.aspx?scid=kb;EN-US;q316666

If you uninstall the packet scheduler, no "bandwidth" is still reserved and regardless of setting and QoS is only valid on your internal network, not after the information reaches your ISP.
