3.4.6 Traffic Shaping
Traffic Shaping is an agreement between the carrier and the receiver to regulate the average rate and “burstiness” or fluctuation of data transmission over an ATM network. This agreement helps eliminate congestion that is important for transmission of real time data such as audio and video connections.
Peak Cell Rate (PCR) is the maximum rate at which the sender is planning to send cells. This parameter may be lower than what the bandwidth of the line permits. 1 ATM cell is 53 bytes (424 bits), so a maximum transfer speed of 2.3Mbps gives a max PCR of 5424 cells/sec. The default value for the Prestige is 5500 cells/sec. This rate is not guaranteed.
Sustained Cell Rate (SCR) is the expected or required cell rate averaged over a long time period. This carrier guarantees this rate as the minimum data transmission rate. SCR may not be greater than the PCR and the Prestige default is 0 cells/sec.
Maximum Burst Size (MBS) is the maximum number of cells that may be sent at the PCR rate in a given time period. The following figure illustrates the relationship between PCR, SCR and MBS.
