In service flow capability updating in a guaranteed bandwidth multicast network may be provided. First, a node may determine that a bandwidth requirement of a flow has changed to a new bandwidth value. Then, in response to determining that the bandwidth requirement of the flow has changed to the new bandwidth value, an ingress capacity value may be updated in an interface usage table for a Reverse Path Forwarding (RPF) interface corresponding to the flow. The RPF interface may be disposed on a network device. Next, in response to determining that the bandwidth requirement of the flow has changed to the new bandwidth value, an egress capacity value may be updated in the interface usage table for an Outgoing Interface (OIF) corresponding to the flow. The OIF may be disposed on the network device.

In one illustrative example, a switch for use in a network fabric which includes a plurality on interconnected switches configured to facilitate communication of IP multicast traffic amongst host devices may be provided. The switch may receive, from a controller, a global set of host policies associated with the plurality of switches of the network fabric. The switch may select, from the global set of host policies, a local subset of host policies applicable to the switch. The switch may grant or deny admission of host devices to receive or send IP multicast traffic flows in the network fabric according to the selected, local subset of host policies.
