Windows 7的網(wǎng)絡(luò)DHCP記憶功能

Win7之家（ m.airtaxifl.com）：Windows 7的網(wǎng)絡(luò)DHCP記憶功能

 據(jù)微軟DHCP團(tuán)隊(duì)博客稱，Windows 7和Windows Server 2008 R2中的DHCP將會包含一項(xiàng)名為DHCP Network Hint的新功能.

表明看來，Windows 7中默認(rèn)狀態(tài)下的DHCP將會顯得更智能，尤其是用戶當(dāng)前使用的網(wǎng)絡(luò)被Windows 7識別為系統(tǒng)曾經(jīng)用過的時(shí)。

如果你使用的網(wǎng)線連接網(wǎng)絡(luò)，你會看到如下提示：“我已經(jīng)獲取了地址租用權(quán)而且并未過期，因此我只想與服務(wù)器進(jìn)行簡短會話以續(xù)訂該地址。”與重新進(jìn)行一次完整會話相比，這樣的過程顯然更高效。當(dāng)然，對于無線網(wǎng)絡(luò)用戶而言，還是得重新完整地來一次。?即使你已經(jīng)獲取了地址且未過期。

這對于經(jīng)常在多個(gè)網(wǎng)絡(luò)中切換的用戶而言，無疑是個(gè)好消息，因?yàn)?a class="s_tag" target="_blank" href="http://m.airtaxifl.com">Windows 7可以幫助用戶記住曾經(jīng)使用過的網(wǎng)絡(luò)。

附部分原文：

Apparently, and by default, DHCP in Windows 7 (and Server 2008 R2) will be more “opportunistic” when it recognizes an SSID for a network that it’s used before.

DHCP on wired stationary network connections has always done this thing where it says, “I already have an address lease, and it’s not expired, so I’m going to have a shorter conversation with the server to allow me to keep this address I already have".  That’s much more efficient than starting the whole request process over again.  Of course, for wireless connections, you always have to do the entire process; even if you’ve been on that network before and may have been able to lease an address that would not otherwise have expired.
