Abstract

In this paper point-to-multipoint and multipoint-to-point connections support for ABR services are examined, forming a foundation for multipoint-to-multipoint connections. Simplicity and scalability of the schemes are the main concerns. In this case, feedback consolidation is required at the branch points to avoid overwhelming the sender with feedback. This paper discusses the various design options and implementation alternatives for consolidation algorithms and proposes different novel algorithms. The performance of the proposed algorithms and the original algorithms are compared under a large variety of realistic configurations and traffic patterns. Results indicate that the branch point consolidation algorithm exhibits stability and a fast transient response.
