mturoute是一個(gè)檢測(cè)你與目標(biāo)網(wǎng)站的mtu值的windows軟件，通過(guò)不斷嘗試發(fā)送不同大小的icmp ping包來(lái)確定mtu大小，由于使用了non-fragment標(biāo)識(shí)，所以當(dāng)發(fā)送icmp包太大，包不會(huì)被重封裝，而是直接丟棄，不返回任何信息；這樣下次就會(huì)選擇個(gè)小點(diǎn)的icmp包來(lái)發(fā)送，直至收到回復(fù)信息~
用法：
mturoute [選項(xiàng)] 目標(biāo)地址
選項(xiàng)：
-t : Toggles 'traceroute' mode. (Default is off)
-f : Allow fragmentation. This will return the max ping size that the target host will respond to, but not necessarily the MTU.
-w : Set the number of milliseconds to wait for a response (default 3000).
-r : Set the maximum number of probe retries on timeout (default = 3).
-i : Set the interval between two echo requests.
-d : Increases the debugging level. Reports ICMP status/failures.
-m : Sets a maximum payload size to test. (Default is 10000)
-v : Print version info and exit.
-z : Fill ICMP packets with random data.
-p : Fill ICMP packets with a specified pattern.
-s : Skip speed optimizations.
-x : Redact IP addresses in output.
-h,-? : Print usage information and exit.
例子：
這里1472字節(jié)就行，但1473字節(jié)就失敗了，所以軟件返回了1500字節(jié)(檢測(cè)的1472字節(jié)+額外的icmp協(xié)議報(bào)頭的8字節(jié)+IP報(bào)頭的20字節(jié))
