Network Bandwidth (2)

• The current record is 6.4Tb/s…

  • ACT 300000 * 256 kbps (Transact) = 73 Gbps

  • ACT 300000 * 2.2 Mbps = 644 Gbps

  • AARNET Backbone Canberra-Sydney, or Canberra-Melbourne : 18 Mbp

• Bandwidth is often non symetric at the end of the network

  • TransACT : 512 / 64 kbps

• No bandwidth is ‘high’ or ‘low’ – it’s just different to what you are used to.
  Which depends on where you are

• It’s not the sustained bandwidth you are catering for – it’s the peaks!
  Internet traffic is fractal
