It includes the following sections:
• Measuring Network Performance for DHCP
• Measuring Network Performance for DLSw
• Measuring Network Performance for DNS
• Measuring Network Performance for HTTP
• Measuring Network Performance for FTP
• Measuring Network Performance for IP
• Measuring Network Performance for SNA

For the IPM Operations, the IPM Request size does not include the size of the headers added by the
respective layers. The header size varies according to the type of the RTR probe.Overhead added by
different layers:
• TCP Layer - 20 bytes.
• UDP Layer - 8 bytes.
• IP Layer - 20 to 60 bytes.
• ICMP Layer - 8 Bytes.
• RTR/SAA - 8 bytes
