7-18CHAPTER 7: NETWORK PERFORMANCE MEASUREMENT TASKS

LEC The LEC Graph Assistant, see Figure 7-14, shows statistics of the message traffic through the LEC. The LEC Statistics are:

Data frames/sec History graph of the transmission rate of data frames through the LEC.

Data Frames Pie graph of the distribution of different types of data frames through the LEC.

Data Utilization Utilization of LEC data transmission rate relative to the maximum possible rate.

Control frames/sec History graph of the transmission rate of control frames through the LEC.

Control Frames Pie graph of the ratio of transmission of different types of LEC control frames.

Data/Control Frames Pie graph of the ratio between LEC data frame transmission and LEC control frame transmission.
