http://blogs.msdn.com/wndp/archive/2006/03/23/559656.aspxSome weeks ago I described 802.1p . It's a way to color traffic on your local network segment. If you have network equipment aware of this tag, you can get strict prioritization at these hops. Still, the tag is at layer-2 and not layer-3; your averageen-USCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.msdn.com/wndp/archive/2006/03/23/559656.aspx#579647Thu, 20 Apr 2006 09:55:34 GMT91d46819-8472-40ad-a661-2c78acb4018c:579647pankaj How the SGW supports &nbsp;DSCP/ToS bits value in the IP packets header differently for voice, data and signaling traffic.http://blogs.msdn.com/wndp/archive/2006/03/23/559656.aspx#594995Thu, 11 May 2006 03:40:58 GMT91d46819-8472-40ad-a661-2c78acb4018c:594995wndpteamRegarding &quot;How does the gateway support DSCP/TOS value in the IP packet header differently for voice, data, and signalling traffic?&quot;: This is really implementation specific; there is no short answer. First, the device must implement a prioritization scheme (queue servicing algorithm for example) that differentiates traffic based on DSCP. Home standards also differ from those focused on enterprise or access networks. For example, in the enterprise, there are RFCs that clearly describe per-hop behaviors (PHB) that directly answer your question. these PHBs can be implemented in most enterprise class routers. In the home, there is no specific standard that defines device behavior. The WiFi WMM (wireless multimedia) specification defines which DSCP values must be used for four categories of traffic (background, best effort, video, and voice), but the MAC implementation really dictates the behavior of traffic in each of these categories. All that said, if a device implements some notion of priority, it is better than nothing. We're seeing many more consumer grade devices that implement priority schemes based on DSCP that enable streaming of high definition (HD) video. In fact, Microsoft requires a good implementation for premium router/gateway/AP devices to receive a Designed for Windows logo.
