Ping Command to test the network speed

Using the ping command to test the network speed is the basis of this method. Let's first take a look at: network speed test-Ping Command help instructions www.2cto.com C: \ Documents and Settings \ Administrator> ping /? Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-I TTL] [-v TOS] [-r count] [- s count] [[-j host-list] | [-k host-list] [-w timeout] [-R] [-S srcaddr] [-4] [- 6] target_name Options: -tPing the specified host until stopped. to see statistics and continue-type Control-Break; To stop-type Control-C. -aResolve addresses to hostnames. -n count Number of echo requests to send. -l sizeSend buffer s Ize. -fSet Don't Fragment flag in packet (IPv4-only ). -I TTLTime To Live. -v TOSType Of Service (IPv4-only ). -r count Record route for count hops (IPv4-only ). -s count Timestamp for count hops (IPv4-only ). -j host-list Loose source route along host-list (IPv4-only ). -k host-list Strict source route along host-list (IPv4-only ). -w timeout Timeout in milliseconds to wait for each reply. -RTrace roun D-trip path (IPv6-only ). -S srcaddr Source address to use (IPv6-only ). -4 Force using limit 4.-6 Force using limit 6. network speed test-Ping command details use ping to test the computer name and computer ip address, verify the connection with the remote computer, verify the connection to one or more remote computers by sending icmp echo data packets to the computer and listening for echo response data packets. This command can only be used after the TCP/IP protocol is installed. Open your ms-dos(open the Startup Program ms-dos.pdf, and use win2000's example to open cmd.exe (this is ms-dos in win2000, start → program → attachment → "command prompt" or start → search for files or folders → "fill in cmd.exe ", find it and double-click it to run it .) Let's take a look at his command: ping [-t] [-a] [-n count] [-l length] [-f] [-I ttl] [-v tos] [-r count] [- s count] [[-j computer-list] | [-k computer-list] [-w timeout] destination-list parameter-t ping the specified computer until it is interrupted. Ctrl + c stop-a resolve the address to the computer name. Example: c :\> ping-a 127.0.0.1 pinging china-hacker [127.0.0.1] with 32 bytes of data :( china-hacker is his computer name) reply from 127.0.0.1: bytes = 32 time <10 ms ttl = 128 reply from 127.0.0.1: bytes = 32 time <10 ms ttl = 128 reply from 127.0.0.1: bytes = 32 time <10 ms ttl = 128 reply from 127.0.0.1: bytes = 32 time <10 ms ttl = 128 ping statistics for 127.0.0.1: packets: sent = 4, received = 4, lost = 0 (0% loss), approximate round trip t Imes in milli-seconds: minimum = 0 ms, maximum = 0 ms, average = 0 ms-n count the number of echo data packets specified by count. The default value is 4. -L length sends the echo data packet containing the data volume specified by length. The default value is 32 bytes. The maximum value is 65,527. -F sends the "Do Not segment" flag in the data packet. Packets are not segmented by the gateway on the route. -I ttl: Set the ttl field to the value specified by ttl. -V tos: Set the "service type" field to the value specified by tos. -R count records the routes of outgoing and returned packets in the "Record Route" field. Count can specify at least one computer and a maximum of nine computers. -S count specifies the timestamp of the number of hops specified by count. -J computer-list uses the computer list specified by computer-list to route data packets. The maximum number of consecutive computers that can be separated by the Intermediate Gateway (routing sparse source) ip addresses is 9. -K computer-list uses the computer list specified by computer-list to route data packets. The maximum number of ip addresses allowed by consecutive computers to be separated by intermediate gateways (strictly source routes) is 9. -W timeout specifies the timeout interval, in milliseconds. Destination-list specifies the remote computer to be pinged.

Using the ping command is a typical and practical skill. I hope you can learn and master it, test your network speed quickly.
