HANDS-ON ACTIVITY 11B

Monitoring AT&T’s WAN

AT&T permits you to monitor their Global IP network. Go to ipnetwork.bgtmo.ip.att.net/pws and click on Look at your world wide network. You’ll see a screen like that in Figure 11.18 which shows the average delay (“latency”) of all the circuits at each of the major PoPs in their global IP network. You can select a city and see the round-trip delay (from the city to the other city and back again). Figure 11.18 shows the delays to and from Indianapolis. All are highlighted in green, which means the delays are below the desired maximum. They range from a low of 13 ms to St. Louis to a high of 60 ms to San Diego. This also displays the percent of packets that have been lost in transit (either due to errors or overloading of circuits). All circuits are below the target maximum of 0.1 percent. The tabs across the top of the screen (e.g., Network Delay, Network Loss, Averages) show summary data across the entire network

Deliverables

1. What is the current latency and packet loss between Dallas and Austin?

2. What is the current latency and packet loss between Phoenix and New York?
