Following the IDI field is the Higher Order Domain-Specific Part (HO-DSP).
This part has an organization identifier (not shown in the figure), which is
a company code assigned to the user. It's followed by the user-designated
portion of the address, then by a 6-byte End System Identifier (ESI) and a
selector byte. The ESI is usually the IEEE 802 MAC address of the d evice.
You can use the selector byte when operating a LAN Emulation Server (LES)
and a Broadcast and Unknown Server (BUS) in the same ATM switch. Because the
LES and the BUS have the same general address but a different selector byte,
this differentiates the two LAN emulation (LANE) services running on the
same switch.

I am looking at the ATM cell structure. I do not see a selector byte. Can
you elaborate?

Hello,
Can someone tell me what is the purpose of the selector byte in ATM?
