The frame size distribution and IPv6 percentage charts are based on sFlow data from the Arista core switch. 1 out of every 1,0478,576 frames are sampled for layer-2 (Ethernet) fields. For the IPv6 chart, the percentage indicated is the result of dividing the octet sum of frames with EtherType 0x86DD (IPv6) by the octet sum of frames of all EtherTypes observed.
Multi-year scale: (data prior to 2007 is approximate)
