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 RP 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 a first QoS is established in response to an RSVP request. When a second RSVP request is ived, a new tree is created if the QoS in the second RSVP request is not within a threshold e 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.

[ What is claimed is:] [1.]1. A method of providing dynamic quality of service in a communications network including a sender communications site, a first receiver communications site and a second receiver communications site, comprising the steps of:receiving a first resource Reservation Protocol (RSVP) request for a connection from the sender communications site to the first receiver communications site, the first RSVP request including first quality of service information;establishing a first RSVP connection tree from the sender communications site to the first receiver communications site, the first RSVP connection tree being a point to multipoint tree with a first quality of service based on the first quality of service information;receiving a second RSVP request for a connection from the sender communications site to the second receiver communications site, the second RSVP request including second quality of service information;establishing a second RSVP connection tree from the sender communications site to the second receiver communications site if the second quality of service information is not within a threshold range from the first quality of service information, the second RSVP connection tree being a point-to-multipoint tree with a second quality of service based on the second quality of service information; andadding a branch from the first RSVP connection tree to the second receiver communications site if the second quality of service information is within the threshold range from the first quality of service information.
