Abstract

Presented herein are methods and systems relating to end-to-end (E2E) multicast traffic redundancy in professional media networks, information-centric networks (ICN), and content-centric networks (CCN). One objective is to bind the path computation capability of a Path Computation Element (PCE) to a multipoint data distribution (e.g., multicast traffic) over both existing and new technologies (e.g., Protocol Independent Multicast (PIM), MultiPoint Label Distribution Protocol (mLDP), Bit Index Explicit Replication (BIER), etc.). Also provided is an E2E disjointed path and maximum redundancy for media traffic (e.g., video) using multicast. A designated router (DR) and a backup DR for a local area network (LAN) queries the server for disjointed paths toward a source by sending a request with a LAN identification (ID), which is used by the server to calculate a disjointed path and stream details.
