Source and destination behavior normally occur in terminals only, but there is an option
to implement Virtual Source (VS) and Virtual Destination (VD) behavior in a switch, as
described in more detail in
An example of rate variation over time of an ABR connection is shown in

Refer to
The instantaneous rate at which the source emits user cells must never exceed ACR,
but may stay below it. Some special situations are identified in
in circles. These are explained as follows:
1. The sending rate remains below ACR. The reason for this could be that the connection
2. Same as 1 with the sending rate dropping below MCR.
3. The sender stops transmitting data. After some time the ACR is reduced to MCR.
4. After the time-out defined by ADTF the connection is allowed to start with ICR, i.e.
Normally RM cells are sent in-rate (within the limits of ACR). However, under well
defined conditions, RM cells may be sent out-of-rate (in excess of ACR).
