Robustness of the quasi-stationary approximation simulatior -0OPCA EFPA 点:5 Service rate of short-lived traffic Figure 2. 12: The average blocking probabilities for the short-lived traffic with different values of H for a 6-node fully-meshed network with 20 links each trunk and u1=1 when the holding times of short-lived calls close to those of long - lived calls the quasi-stationary approximation is inaccurate when the holding times of short -lived are significantly shorter than long- lived the quasi-stationary approximation accurate The errors shown in this condition are mainly due to overflow error and path error discussed above >quasi-stationary approximation accurate when the average holding times of short-lived calls is less than 5% of the average holding times of long-lived calls 23Robustness of the quasi-stationary approximation 23 when the holding times of short-lived calls close to those of long-lived calls the quasi-stationary approximation is inaccurate. when the holding times of short-lived are significantly shorter than long-lived the quasi-stationary approximation accurate. ➢The errors shown in this condition are mainly due to overflow error and path error discussed above. ➢quasi-stationary approximation accurate when the average holding times of short-lived calls is less than 5% of the average holding times of long-lived calls
