Lan speeds

  1. 1. SMC Networks Speed in LAN Networks
  2. 2. Most common LAN Standards 802.11n 450Mbps Fast Ethernet Gigabit Ethernet HomePlug AV HomePlug Turbo 802.11b 802.11n 300Mpbs HomePlug 1.1 10GbE 802.11n 150Mbps 802.11g 802.11a 802.11g Turbo 54Mbps 11Mbps HomePlug 1.0 802.11ac 1Gbps
  3. 3. Most common LAN Standards Wired Ethernet Wireless Ethernet HomePlug 802.11n 450Mbps Fast Ethernet 802.11g Turbo HomePlug AV Gigabit Ethernet 802.11b HomePlug Turbo 10GbE 802.11g HomePlug 1.1 802.11n 300Mpbs HomePlug 1.0 802.11n 150Mbps All defined by 54Mbps IEEE 802.3 and different 802.11ac 1Gbps standards 802.11a (802.3u, 802.3z, 11Mbps 802.3an, etc)
  4. 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
  5. 5. Speed vs. Throughput Wired Ethernet Speed Mbps Throughput Mbps Ethernet 10 9 Fast Ethernet 100 90 Gigabit Ethernet 1000 450-800 10G Ethernet 10000 ??? HomePlug 14 5 HomePlug 1.0 HomePlug 1.1 (same as 1.0 Turbo) 85 30 HomePlug AV 200 70
  6. 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. 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
