Abstract

Native multicast is critical for scaling the delivery of high-bandwidth data, such as audio and video, to multiple receivers. Until recently, however, multicast routing has been unstable, thus making it difficult to ensure robust data delivery.The authors' in-depth analysis of routing instabilities in the multicast infrastructure seeks to identify underlying inconsistencies among routing views at different routers and characterize instabilities by evaluating temporal and spatial variations in these views. Results are based on Multiprotocol Border Gateway Protocol (MBGP) routing tables.
