Abstract
Multiple Register State Machines on a rendezvous point router ('RP') in a Protocol Independent Multicast-Sparse Mode ('PIM-SM') domain per (S,G) is supported, thereby increasing the Register state consistency and faster convergence in case of a first hop router (“FHR”) failure. Such example embodiments may advantageously eliminate the limitation of a single Register State Machine on RP for a given (S,G), in the presence of multiple FHRs connected to the same source. At least some such example embodiments provide the capability of maintaining multiple Register State Machines on RP for a given (S,G), in a way, that maps one Register State Machine to each FHR. In this way, the RP can avoid the inconsistent FHR states and traffic losses caused due to FHR failures.
