Design and Experience With Supporting NAT and Firewall in End System Multicast

Tags:
firewalls

Overview End System Multicast (ESM) is an overlay based architecture to enable multicast in the Internet, and the application-endpoint model of deploying ESM shows tremendous promise because there is no dependence on dedicated infrastructure. However, the presence of Network Address Translators (NAT) and firewalls challenges the deployment of ESM and other such systems because NATs and firewalls impose fundamental connectivity constraints. Although several net-work level solutions have been proposed, none have been well deployed, therefore there is a need for an application level solution to support NAT and firewall that is immediately deployable by application-endpoint based systems.
