EC2 instance types's exact network performance?

Question

I cannot find exact network performance details for different EC2 instance types on Amazon. Instead, they are only saying:

• High
• Moderate
• Low

What does this even mean? I especially want to know the exact amount of Traffic-OUT on each instance type.

I need to do live streaming and my stream bit rate will be 240kbps. So I need to know which instance type can handle how many concurrent viewers.

For t2/m3/c3/c4/r3/i2/d2 instances (All average values) from varied sources:

• t2.nano = 20-30 MBit/s
• t2.micro = ~70 MBit/s (qiita says 63 MBit/s)
• t1.micro = ~100 Mbit/s
• t2.small = ~125 MBit/s 
• t2.medium = ~250-300 MBit/s
• c1.medium = ~800 MBit/s. 
• m3.medium = ~400 MBit/s
• *.large = ~450-600 MBit/s 
• *.xlarge = 700-900 MBit/s
• *.2xlarge = ~1 GBit/s +- 10%
• *.4xlarge = ~2 GBit/s +- 10%
• *.8xlarge = ~8.5 GBit/s, to attain full throughput you need to enhance VPC and Networking.

For large instances:

• m1.large = ~800 Mbit/s
• t2.large = ~500 MBit/s
• c3.large = ~500-570 Mbit/s
• c4.large = ~520 MBit/s
• m3.large = ~700 MBit/s
• m4.large = ~445 Mbit/s
• r3.large = ~390 Mbit/s
