Microsoft makes part of Network Monitor open source...
Microsoft's Network Monitor developers have announced, on their blog, that they are planning to open source part of the parsers in Network Monitor 3.2. In Network Monitor, a parser is a component which breaks down and identifies network packets for analysis. Network Monitor users can already create their own parsers.
What the Network Monitor developers will be releasing appears to be the set of parsers they have created to parse Microsoft's network protocols. The developers are inviting third parties to enhance and add parsers to the project. Currently the project site has not been published, and there are no details of what the open source licence will be.
There is no official release date for the Network Monitor 3.2, though it may be imminent as the developers suggest the first update for the parsers will occur in October. Network Monitor 3.2 itself is still in beta and only available to registered members of Microsoft's Connect programme. Apart from the parsers, no other part of Network Monitor is being open sourced at this point.
