Network performance test Tools Iperf and MTR

Iperf

Iperf is a tool for measuring network throughput performance, which can test the throughput of TCP or UDP, and in order to perform iperf testing, a connection must be established between the server (to discard traffic) and the client (to generate traffic).

The Iperf has TCP and UDP two test modes, respectively, as described below

Tcp

• Measuring network bandwidth

• Report the size and observations of the MSS/MTU value

• Supports TCP window values through socket buffering

• Multithreading is supported when a P thread or WIN32 thread is available. Client and server support simultaneous multi-connection

Udp

• Clients can create UDP streams of specified bandwidth

• Measure Drop Packets

• Measurement delay

• Support Multicast

• Multithreading is supported when P threads are available. Client and server support simultaneous multi-connection (Windows not supported)
  

Common parameters:

-S is specified as server mode

-C specified as client mode

-U is specified as UDP

-B Specify Bandwidth

-t specifies the time of measurement

-I specify test interval

Example:

Iperf–s-u–p 12345–i 1 runs iperf on the server side and is a UDP test

Iperf-c server-ip-p server-port-i 1-t 10-b 1000M run Iperf on the client.

MTR

The MTR combines the functions of traceroute and Ping in a network tool, starting with the MTR and sending a packet with a low TTL by destination to check the network connection between the host running the MTR and the destination host. By continuously sending a low TTL packet, and recording the response time of the intermediate router. In this way, the MTR records the percentage of response packets arriving at the destination host node and the time of the response packet. Sudden drop-out rates and longer response times will reflect a bad connection.

Mtr-h provide help commands
Mtr-v displaying the version information of the MTR
Mtr-r Display in report mode

Mtr-s used to specify the size of the ping packet

Mtr-n No-dns IP address does not do domain name resolution

Mtr-a to set the IP address of the sending packet this is useful for a host by multiple IP addresses

Mtr-i Use this parameter to set the requirement between ICMP returns by default is 1 seconds

Mtr-4 IPv4

Mtr-6 IPV6
