Traceroute is a computer network diagnostic tool for inspecting and displaying the path (route) and measuring transit delays of packets across an Internet Protocol (IP) võrk. Ajalugu marsruut on salvestatud, kui round-trip korda paketid saadud iga järgnev vastuvõtva (remote sõlme) lennuliini (tee); summa tähenda korda iga-hop näitab kogu aeg, kulutatud, et luua ühendus.
Traceroute tulu, välja arvatud juhul, kui kõik (kolm) saadetud paketid on kaotanud rohkem kui kaks korda, siis ühendus katkeb ja marsruudi ei saa hinnata. Ping, teiselt poolt, ainult arvutab final round-trip korda alates sihtkoht. Traceroute is a handy tool for understanding where problems are in the Internet network. Each computer on the traceroute is identified by its IP address.
The journey from one computer to another is known as a hop. The amount of time it takes to make a hop is measured in milliseconds. The information that travels along the traceroute is known as packets. Aside from being an entertaining exercise, requesting a traceroute also has more practical uses.
If you are having difficulty accessing a particular website or computer, näiteks, performing a traceroute allows you to quickly see where the problem is occurring. When a traceroute has difficulty accessing a computer, it will display the message “Request timed out.” Each of the hop columns will display an asterisk instead of a millisecond count. On occasion, a traceroute will show one hop time, with the next two columns displaying asterisks.
This usually indicates that although one packet was accepted by the computer, the other two packets were discarded. This is not unusual; due to security concerns, many computers routinely reject multiple packages, or forward them to different sources.
