| A relatively
new concept. Based on flow
control from the |
|||||||||||
| network
(employing Resource Management = RM cells). In |
|||||||||||
| ABR, we need
to specify the following traffic parameters: |
|||||||||||
| - Peak Cell Rate (PCR) |
|||||||||||
| - Minimum Cell Rate (MCR) |
|||||||||||
| MCR is a bound (0 < MCR < PCR) on the
cell rate that the |
|||||||||||
| network should
support. However, the cell rate of the |
|||||||||||
| source is
allowed to vary between 0 … PCR. |

| Typical
applications: |
|||||||||||
| - LAN emulation / LAN interconnection |
|||||||||||
| - File transfer (critical applications) |
