![]() First, the command sends three ICMP ECHO messages to the "ping" target with a TTL of 1.This is done with "creative" use of the time-to-live (TTL) field in the IP packet.traceroute ( tracert) - this is similar to ping, but different in that it sends ICMP ECHO messages to each node along the path to a destination.This function is useful when you want to force more data through the network, which cna reveal problems that a small 32 byte message (the Windows default size) will not reveal. The -l parameter is used to change the data size in the ECHO message (the sent message) and therefore in the ECHO REPLY message.In Windows, two important parameters for testing are -t and - l The -t parameter is used to specify that the operation should run until interrupted (with CTRL + C).If the target IP address both receives the request and is configured to allow responses, it will send back an ECHO REPLY ICMP message (TYPE 0 ICMP message). The sendor sends an ECHO ICMP message (TYPE 8 ICMP message) to the target IP address. Ping is used to attempt an Internet Control Message Protocol (ICMP) communication with a remote host based on the IP address. Ping - most OSes and switches/routers have this feature.Some tools that analyze conneciton issues and view client device parameters, settings and cabailities include ping, traceroute, pathping, nslookup, netstat, and netsh (win32). TamoSoft Throughput Tester - this is a GUI based throughput tester that can test both TCP and UDP traffic.To test the uplink, the wireless client should be configured as the iperf client. So, if you're testing a wireless client, to test the downlink, the wireless client should be configured as the iperf server. typically the default behavior of iperf is to test the throughput from the client to the server. iPerf3 - this is a client/server throughput tester.On a WLAN, useful throughput is always less than the data rate because of management traffic overhead. To repeat, throughput is not a simple factor of data rate. The contention for the wireless medium must also be considered. ![]() ![]() Data rate is a major factor in determining network throughput for a user, but it is not the only factor. Higher data rates use more sophisticated modulation and coding schemes and require better RF/signal conditions than lower data rates. Data rate is the rate at which bits can be sent across the wireless medium, and is entirely dependent on signal quality and the modulation and coding scheme ( MCS) used. When testing wireless (802.11) throughput, remember that you're not testing data rate. ![]()
