Response Time
Note NAM uses the TCP three-way handshake to calculate network delay. If there are no new TCP
connections during the polling interval, the NAM GUI displays a dash (-) for the delay value indicating
there is no delay data for that interval.
Table 3-10, Server Network Responses Window, provides definitions of each field of the Server Network
Response Times window.

Maximum of the Server Network Time (network time between a server and
NAM probing point).
Average Network Time Average of the network time between client and server. Network Time is the
sum of Client Network Time and Server Network Time. NAM measures the
Network Time using TCP 3-way handshakes. If there are no new TCP
connections made during the monitoring interval, this metric is not reported.
Maximum Network Time Maximum of the network time between client and server.
Server Bytes Number of TCP payload bytes sent from the server(s) during the monitoring
interval.
Client Bytes Number of TCP payload bytes sent from the client(s) during the monitoring
interval.
