Abstract: In an aspect, an embodiment of the present disclosure is directed to network control topology that implements a centralized network controller to deterministically assign, and reassign, underlay multicast groups according to one or more policies and/or parameterized intent of the network administrator. The centralized network controller, in some embodiments, comprises a map server-neap resolver controller configured to provide deterministic and centralized allocation of underlay multi cast groups, e.g., to provide security, traffic engineering, network and resource management.

Abstract: A multicast state is generated within a Layer 2 (L2) fabric through a set of L2 tunnel router devices within the L2 fabric. The multicast state is generated without forwarding multicast traffic through Layer 3 (L3) gateways. When a data packet is received for distribution to other devices in the L2 fabric, an underlay multicast tree is defined at an L2 tunnel router device that is to serve as the multicast source for the data packet in the L2 fabric. The data packet is streamed to the other devices through the L2 tunnel router device along the underlay multicast tree without forwarding the data packet through the L3 gateways.

Abstract: According to certain embodiments, a system comprises one or more processors and one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the system to perform operations. The operations comprise selecting a primary node to replicate multicast traffic and forward the multicast traffic to a plurality of receivers, selecting one or more secondary nodes to provide node-level redundancy for the primary node, and providing the one or more secondary nodes with synchronization information that enables the one or more secondary nodes to replicate the multicast traffic and forward the multicast traffic to the plurality of receivers in response to the primary node becoming unavailable. Selecting the primary node is based in software.

Abstract: In an aspect, an embodiment of the present disclosure is directed to network control topology that implements a centralized network controller to deterministically assign, and reassign, underlay multicast groups according to one or more policies and/or parameterized intent of the network administrator. The centralized network controller, in some embodiments, comprises a map server-map resolver controller configured to provide deterministic and centralized allocation of LISP underlay multicast groups, e.g., to provide security, traffic engineering, network and resource management.
