QoS Capabilities for Mesh/Torus <strong>Fabric</strong>s<br />

When routing a Mesh or Torus fabric, multiple SLs and VLs are needed for routing<br />

for each v<strong>Fabric</strong>. This is in contrast to Fat Tree and other topologies that are<br />

routed using the shortestpath algorithm. The shortestpath algorithm uses exactly<br />

1 SL and VL per QoS-enabled v<strong>Fabric</strong>.<br />

The table in Appendix D shows various combinations of Mesh/Torus topologies<br />

and the QoS and MTU capabilities of the fabrics.<br />
