G’Day, my name is Brad Williamson, a Software Design Engineer with the Windows Networking Developer Platform (WNDP) group here at Microsoft. I am going to talk about two APIs that were introduced in Windows Vista Beta 2 to simplify the process of connecting...

In my previous posts about WMM support in Vista, I described how Windows network applications can indicate which priority level they desire for traffic sent, and how Native WiFi (NWF) drivers can identify this traffic to provide appropriate prioritization...

Last week I added QOS2 calls to a sample Winsock application to obtain DSCP marking. The second request we get from developers is to shape their outgoing traffic, i.e. limit the rate at which their traffic is sent. With Vista you configure this on your...

Hi, my name is Jonathan Silvera and I am the WinINet and WinHTTP Program Manager. Today I would like to talk to you about changes we have made to add IPv6 support in the WinINet and WinHTTP WPAD helper functions. The explosion of the Internet in the...

Hi, I’m Reymarx Gereda, SDET at the Networking Development Platform in the Windows team. Recently I saw a question in one of the MSDN forums about calling WinInet API from managed functions; this is something we did for testing the component, and here...

Recently, a number of current and former System.Net team members have posted about various managed code network programming topics: Proxy configuration with HttpWebRequest Socket programming considerations HttpWebRequst & Pipelining ...

Hopefully you've read the previous entry with the QOS2 sample. Here are the answers to questions you might have. What header file do I need to include? qos2.h Is this only for user-mode applications? yes it is. However, leave us a comment if...

If you’ve ever had to deal with Winsock LSPs, then you probably know that handling select function calls are rather convoluted – especially with certain apps that pass multiple socket types into select. Some applications (like IE) will pass a UDP/IPv4...

Over the past few months we've been receiving feedback from partners on the new QOS2 API I just wrote about . The first question is often: how do I use this new API in my application? So I thought we should introduce some of the API calls by modifying...

A common question we get when configuring HTTP.sys to listen on a URL (though HttpAddUrl , HttpAddUrltoUrlGroup , HttpListenerPrefixCollection or even CREATE ENDPOINT ) is how you claim and protect your name space. The first issue that people need...

Back when Windows Server 2003 SP1 shipped, HTTP.sys hit an important milestone, WOW64 support. What is WOW64 support and why is it important? I’m glad you asked. WOW64 lets 32 bit applications run on top of 64 bit windows. WOW64 support for HTTP.sys...

After XP, when we reviewed the scenarios for QoS in Windows, we considered the following 4 big categories: I'm a network administrator who wants to control how the traffic from the computers on my domain will be marked with priority (DSCP). I...

A while back I wrote about the fundamentals of networking Quality of Service (QoS) including 802.1p and DSCP . Gabe recently wrote about WMM . With Vista soon to hit the market, it's time for us to talk about the new and old QoS APIs. Let's start with...
