Routing support for point-to-multipoint connections
First Claim
1. A method comprising:
- receiving information about routing selections; and
dynamically creating a distribution tree representing a point-to-multipoint connection within a computer network according to routing selections made for at least one point-to-point connection of the point-to-multipoint connection.

Abstract
A distrubution tree for point-to-multipoint connections within a computer network may be dynamically created according to the number of connections shared by individual point-to-point connections which comprise the point-to-multipoint connection. Each distribution tree represents a collection of DTLs, overlapped from a root node of the tree to leaf nodes thereof. The distribution tree may be organized as a distribution table having two dimensions with row indices thereof comprising PNNI node indices of succeeding nodes along a connection DTL. Individual entries in a first column of the distribution table may indicate PNNI node indices of proceeding nodes along the connection DTL. Individual entries in a second column of the distribution table may indicate the number of point-to-point connections for the point-to-multipoint connection that use a link connecting a pair of proceeding and succeeding nodes. A path (or sub-path) may be selected from the distribution table in response to a request for a point-to-multipoint connection within the ATM network. Further, the distribution table may be updated in response to a call being added or dropped within the network.
