Re: [15-04-0134-00-003b-Octet Transmission Order for OUI-derived Numbers]

Abstract: [The document discusses octet transmission order for OUI-derived numbers]

Purpose: [Recommend that IEEE 802.15.3 adopt uniform octet transmission order conventions forOUI-derived numbers]

IEEE Std 802.15.3-2003Bit and Octet Transmission Order

“Octets within numeric fields that are longer than a single octet are depicted in decreasing order of significance, from highest numbered bit on the left to the lowest numbered bit on the right. The octets in fields longer than a single octet are sent to the PHY in order from the octet containing the lowest numbered bits to the octet containing the highest numbered bits.”

Universal Address (MAC-48)

A Universal Address is a sequence of six octets. The first three take the values of the three octets of the OUI in order. The last three octets are administered by the assignee. The binary representation of an address is formed by taking each octet in order and expressing it as a sequence of eight bits, least significant bit (lsb) to most significant bit (msb), left to right. For example, the OUI AC-DE-48 could be used to generate the address AC-DE-48-00-00-80 which has the binary representation:

DEV Address Transmission Order
  • Hypothetical DEV Address
    • Numeric value ACDE 4823 4567 ABCD16
    • Canonical representation AC-DE-48-23-45-67-AB-CD
    • Octet AC16 is arguably the most significant

recommendations
Recommendations
  • Agree on uniform octet transmission order conventions for OUI-derived numbers
  • Specify octet transmission order conventions in IEEE P802.15.3a
    • OUI 24 bits
    • LLC/SNAP 40 bits
    • DEV Address 64 bits
