Vista's TCP/IP Promises and Perils

Posted by kdawson on from the packet-to-go dept.

boyko.at.netqos tips us to a new writeup on Vista's TCP/IP stack, which is called Compound TCP/IP (CTCP). From the article: "...security policy will come from a centralized source. When you get your DHCP lease, your computer will report to the stack what OS you're using, what version level, what patches, what anti-virus software that's active — all that kind of stuff. It will have the ability to restrict your network access if you have a down-level machine... We could see a lot of our customers with much higher WAN network utilization because of this new TCP/IP stack... CTCP can be enabled/disabled from the command prompt but there has been no mention of tuning parameters which leads us to ask the question: How are you supposed to configure this setting in Vista?... What worries us... is that Microsoft is basing this on packet round trip time. The round-trip time from the client-side will have the server processing time in it; but the clients aren't likely going to be the running the CTCP at first. If you have a server-to-server backup running, for example, CTCP may think its part of the round-trip time and it'll throw the delay window through the roof..."

    Yeah, trust a blind man to invent a new pencil...

    It seems that M$'s vision of having your computer being nothing more than a "content delivery device" that you have to buy and they control is coming to fruition.

    It is amazing to me how far those people that use M$ products will allow themselves to be, 0wn3d.

    Change is hard and scary, but why would one ever actually pay to be treated in the manner M$ wants to treat you.

    Sheep.

    Cheers

    Downlevel = Anything from MS that's not => Windows 6.0 and everything not sold by MS.

    At least that's my guess.
