You are the network administrator for an Internet Service Provider (ISP). Your company has been asked to provide bandwidth for a live event produced by one of your clients.
You have been asked to calculate the total data transfer required for the event. You have also been asked to verify that your Internet connection can support the maximum estimated concurrent listeners. You have a 45-megabits-per-second (Mbps) connection to the Internet (a T3 circuit).

Event details
• Time of the event: 6:00 P.M.-8:00 P.M.
• Encoding rate: 22 kilobits per second (Kbps)
• Average length of play: 60 minutes
• Total listeners: 1,500
• Concurrent listeners: 1,200

Calculation 1: Calculate the total data transfer for the live event.

Calculation 2: Calculate the required internet connection bandwidth.

1500x60x60x22000 bits = 118800 Mb

Calculation 2: Calculate the required internet connection bandwidth.
1200x22000 bps = 26.4 Mbps
