New Alphabet Soup

without comments

In a high-tech job (but also any other job) change requires to learn the new lingo. Like Obama, I like the change. I consider this fun (and I WILL change the world)

While I’m waiting for Assaf to create the next-gen soup, here is the partial list of abbreviations and their meaning I have to learn. In some cases, it takes me 20+ years in time…

Eat this alphabet soup to get  success

  • AUI : Attachment Unit Interface, originally connected to a MAU
  • MAU : Medium Attachment Unit, like a 10Base-2 transceiver.
  • XAUI : A 10G AUI, the X is the Roman numeral for 10; Data path is 4×3.125Gbps Lanes
  • XLAUI : A 40G AUI, XL being the Roman numeral for 40; Data path is 4×10.3.125Gbps Lanes
  • CAUI: A 100G AUI, C (you guessed it) being the Roman numeral for 100; Data path is 10×10.3125Gbps Lanes
  • MII : Medium Independent Interface, 4bit wide data path.
  • RMII : Reduced MII, the MII but with less signals!
  • SMII : Serial MII, the data path is reduced to one bit.
  • GMII : Gigabit MII, 8bit wide data path.
  • RGMII : Reduced Gigabit MII.
  • SGMII :  Serial Gigabit MII.
  • XGMII : 10G MII (this time the G made it in).
  • XGXS : XGMII eXtender Sublayer.
  • XLGMII : 40G MII.
  • CGMII : 100G MII.
  • MAC : Media Access Controller.
  • PLS : Physical Layer Signaling; for 10Mbps only, implemented the Manchester encoding.
  • RS : Reconciliation Sublayer.
  • PCS : Physical Coding Sublayer; e.g. 8B/10B.
  • MLD : Multi Lane Distribution
  • PMA :  Physical Medium Attachment.
  • PMD : Physical Medium Dependant.
  • IPG : Inter Packet Gap; Code words sent between valid Ethernet Frames.
