Chapter 12, Problem 10Q

Explanation of Solution

Statistics that related to network uptime and downtime and their importance:

Mean time to diagnose (MTTD):

MTTD measures the efficiency of internal testing and problem management personnel. It can be used to compute the capacity of network personnel to separate and identify the failure of hardware, software, or circuits that can be frequently improved by training.

Mean time to respond (MTTR):

MTTR specifies how fast vendors and internal groups respond to problems. It can lead to a change of vendors or internal management’s policies or severe stress on vendors who do not quickly respond to the problems. It can be influenced by presenting vendors or internal groups by determining their previous response times.

Mean time to fix (MTTF):

MTTF measures the time taken for the vendor or internal group to clear the problems once they reach the locations...
