“…PIM-SM is the best and most widely implemented candidate [3]. With regard to proprietary protocols, [6] also analyzes the Next Branch Multicast (NBM) [11], Global Multicast Routing Protocol (GMRP) [12], Domain Constrained Multicast (DCM) [13], and Policy Aware QoS Inter-domain Multicast Routing (PAQoSIDMR) [14] in terms of video broadcast support and inter-domains. The NBM and DCM seem to be adequate to support video multicast, and PAQoSIDMR builds multicast trees to account for QoS requirements.…”

“…PIM routers are needed only in the RP entities and inside of the domains, which is where traditional multicast is performed. The unicast tunnel structure for confining traffic combines solutions described in [13], [19]. The former addresses the issue of multicast traffic confinement by the employment of special IPv6 multicast addresses.…”

IPTV broadcast channels and video content distribution are increasingly saturating network paths. New solutions based on inter‐domain multicast protocols could contribute to the enhancement of multimedia content distribution over the Internet. The aim of this paper is to propose new capabilities for an existing inter‐domain multicast protocol, the Protocol Independent Multicast‐Sparse Mode. We describe the modified protocol and analyze its behavior using newly developed tools based on an open‐source software simulator. The resulting protocol does not require topology information, which is advantageous for easier deployment. In addition, the adopted solution avoids inherent problems with inter‐domain multicast routing, such as multiple paths and path asymmetries.
