inverse multiplexing for ATM (IMA)
A feature available on Nortel Multiservice Switch nodes that supports the
transparent transmission of ATM cell data over a link group. IMA transparently
distributes a single stream of ATM layer cell traffic onto multiple physical links
for transmission across the links, and then combines the traffic back into the
original ATM layer cell sequence at the remote end.
inverse multiplexing for frame relay (IMUX)
A frame-based inverse multiplexing function provided by the multilink frame
relay (MLFR) service.
inverse-UPC shaping
This form of shaping uses dynamic rate changes so that the resulting cell
stream exactly conforms to the requirements of a dual leaky bucket UPC
enforcer. Also known as dual-leaky-bucket or VBR shaping.

IP address owner
The VRRP router that has the virtual router's IP address(es) as real interface
