Information in local and global networks is transmitted in chunks, called packets. Due to the fact that in the procedure for transmitting packets on the Internet, as a rule, several dozen intermediate nodes are involved, there is a possibility of losing information packets. To determine the quality of communication with any specific node in the network, the procedure for counting packets lost during transmission from a specific computer to a specific website is performed.
Instructions
Step 1
Use the ping utility provided with standard operating system programs to determine the number of dropped packets. It is designed specifically to check the quality of network connections based on the TCP / IP protocol. The utility will send test requests (ICMP Echo-Request) to the host that you specify to it, and will record the fact of receiving or not receiving responses (ICMP Echo-Reply). For each request sent, the utility also shows the time between sending and receiving a response.
Step 2
Launch a command line terminal. To do this, you need to use the program launch dialog, which is invoked by the Run command placed in the main menu on the Start button, or by pressing the win + r key combination. In the dialog enter cmd and press the Enter key.
Step 3
Type ping in the command line and enter the domain name or ip-address of the host, the quality of connection with which you are interested in, separated by a space. Then press Enter and the utility will start sending test packets, displaying a line by line report on each response received. Upon completion of the process, the terminal window will display the number of sent packets and the percentage of losses, as well as the average time between sending and receiving.
Step 4
Use the -n switch to set the number of packages in a batch if the default value of four packages is not to your liking. This key must be specified after the address of the pinged node, separating it with a space, and after the key, and also with a space, you must enter a numeric value. For example, to send 12 packets to google.com, enter the following command: ping google.com -n 12.
Step 5
Type ping /? and press Enter if you want more detailed help on additional parameters that can be used with this utility.
