Example CT Bandwidth Sharing with RDM
Below is a simple example with two CT values (CT0, CT1) and one priority 0 as shown in
Figure 24.
Figure 24: RDM with Two Class Types
Suppose CT1 bandwidth, or the CT1 percentage of Maximum Reservable Bandwidth to be more
accurate is 100 Mbps and CT2 bandwidth is 100 Mbps and link bandwidth is 200 Mbps. BC
constraints can be calculated as follows.
BC1 = CT1 Bandwidth = 100 Mbps.
BC0 = {CT1 Bandwidth} + {CT0 Bandwidth} = 200 Mbps.
Suppose an LSP comes with CT1, setup and holding priorities of 0 and a bandwidth of 50 Mbps.
