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..."

    How can a reply that states in the very first sentence that he hasn't read the article be moderated as "informative"?

    I haven't read TFA, but based on blurb it will be horrible. You say that as if you expected something different from Slashdot.

    The point is to avoid the hassles of 802.1n (i.e. tying MACs to ports based on a facilities diagram) and still reap some of the benefits of same.
    Joe Contractor brings his Vista laptop in -- no A/V, no access. Jane Vendor brings her laptop in -- not up-to-date on patches, no access. All without
    requiring those laptops to have some third party service installed/configured.
