Network based filtering architecture on a shared multicast tree

Abstract

This paper introduces a shared tree multicast filter that uses labels to create one-to-one, one-to-many and many-to-many communication on an existing multi cast tree. All the receivers wishing to communicate privately will be connected virtually by a label to form a subtree within an existing multicast tree. The data packet is sent to the receivers on paths identified by the label. A label manager on the tree will create and manage these labels. This paper describes the benefits of using our filter architecture compared to creating a new multicast tree or using another proposed filter architecture.
