A method and apparatus for providing provisioned and dynamic QoS in a communications network. In one embodiment, provisioned QoS is provided in a network using NHRP by deciding to establish an SVC for a sender and receiver. An NHRP resolution reply containing QoS information is received in response to an NHRP resolution request. An appropriate SVC is then established using the QoS information. In another embodiment, dynamic QoS is provided in a network using RSVP. A first RSVP multicast connection tree with a first QoS is established in response to an RSVP request. When a second RSVP request is received, a new tree is created if the QoS in the second RSVP request is not within a threshold range from the QoS of the first tree. If the QoS in the second RSVP request is within the threshold range, a new branch is added to the first tree and no new RSVP connection tree is required.
