4. Speed vs. Throughput
SPEED – Data Transfer Rate at physical Layer
THROUGHPUT – Data Transfer Rate at TCP/UDP Layer after removing
the OVERHEAD (IP, MAC and physical)
Session
The two rates can never be the same,
(throughput will be lower) but there TCP/UDP
are standards more overhead
efficient than others. IP
MAC
Physical
6. Speed vs. Throughput
Wireless Ethernet Speed Mbps Throughput Mbps
802.11b 11 8
802.11a 54 20
802.11g 54 20
802.11g Turbo 108 30-40
802.11n 150 150 50
802.11n 300 300 80
802.11n 450 450 ??
802.11ac UNDER DEVELOPMENT 1000 ??
This values are maximum rates and they can decrease a lot with the distance and link quality.
7. Storage vs. Networking Metric
Storage
To measure data storage it is used a mib (mebibit) as 1.048.576 bits
Networking
In networking however it is used the mb (megabit) as 1.000.000 bits
1 Byte = 8 bits
1 MB = 8 Mbits
1MBps = 1MB/sec = 8 Mbps
1000Mbps = 125 MB/sec = 125 MBps
