Problems solved by technology

This method is processor intensive for the agent appliance and delays the computation of the new aggregate state for the interface
Also, while the aggregated state based on all circuits is being reprocessed, any changes to the state of circuits that have already been processed will also require reprocessing

Abstract

In a proxy (107) for an upstream multicast router (103) using IGMP or MLD, by tracking the multicast source of multiple multicast sources (101) required by the aggregation status of multiple multicast subscriber nodes (109) A subset of (101), the process manages the interface between upstream multicast routers (103) and proxies (107) in an efficient and scalable manner. Tracking uses interface tracking tables to determine the aggregate state of an interface, rather than tracking the Forwarding Information Base (FIB) and Membership Database detailing more specific data for each multicast source (101) required by each multicast subscriber node (109) . The procedure receives an IGMP or MLD membership report with at least one change in the set of multicast sources (101) to be received on the interface, updates the interface tracking table to reflect the at least one change in the subset of multicast sources (101), and sets at least A change is notified to the upstream multicast router (103).

Description

technical field [0001] Embodiments of the present invention relate to methods and systems for improving the efficiency and scalability of multicast subscriber management at downstream proxy devices. In particular, embodiments of the present invention relate to managing aggregation states of interfaces between downstream proxy devices and upstream multicast routers using interface tracking tables for multicast sources with respect to aggregation requirements of multicast subscriber nodes. Background technique [0002] A proxy device is used in a multicast network to manage forwarding and blocking of multicast sources between a set of multicast subscriber nodes and upstream multicast routers. An upstream multicast router is directly connected to a multicast source, or an intermediary device is indirectly connected to a multicast source that provides content to a set of multicast subscriber nodes. A proxy device is a Level 2 (L2) device that manages a membership database for a...
