Method and apparatus for managing a network component change
First Claim
1. A method of managing a network component change in a data communications network having as components nodes and links defining a pre-change topology, comprising the steps, performed at a transitioning node, of:
- forwarding all data assigned to the pre-change topology via the pre-change topology;
defining a post-change topology;
assigning all data assigned to the pre-change topology to the post-change topology;
transitioning from the pre-change to the post-change topology;
forwarding the data assigned to the post-change topology via the post-change topology;
assigning the pre-change topology to a first topology space and the post-change topology to a second topology space;
after transition to the post-change topology, rendering the first topology space congruent with the second topology space; and
transitioning from the post-change topology in the second topology space to the first topology space.

Abstract
A method is disclosed of managing a network component change in a data communications network having as components nodes and links defining a pre-change topology. A transitioning node forwards all data assigned to the pre-change topology via the pre-change topology. The transitioning node defines a post-change topology. The transitioning node transitions from the pre-change to the post-change topology. Data assigned to the pre-change topology is assigned to the post-change topology, and the transitioning node forwards the data via the post-change topology.
