A multicast cloud controller ('MCC') in a cloud system implements a process to manage multicast traffic in a cloud network. The MCC is coupled to at least one virtualized server for hosting one or more virtual machines ('VM'), wherein the virtualized server comprises at least one virtual switch (&#x201c;VS&#x201d;) that supports multiprotocol label switching (MPLS) and the virtual switch is coupled to a top of rack switch (&#x201c;TORS&#x201d;) that supports MPLS. MPLS is utilized to support multicast data traffic in the cloud system such that the system and method reduces state and is scalable.

A method implemented by a network topology design system, the network topology design system including a processing device. The method to determine placement of a controller within a network with a split architecture where control plane components of the split architecture network are executed by a controller and the control plane components are separate from data plane components of the split architecture network. The placement of the controller is selected to minimize disruption of the split architecture network caused by a link failure, a switch failure or a connectivity loss between the controller and the data plane components.

Controller placement for fast failover in the split architecture

A network topology design system to determine placement of a set of controllers within a network with a split architecture, the placement of the set of controllers selected to minimize disruption of the split architecture network caused by a link failure, a switch failure or a connectivity loss between the set of controllers and the data plane components. The system performs a method including graphing a topology of the split architecture network, determining a set of clusters of nodes within the graph by applying an agglomerative clustering process or a partitive clustering process, determining, a centroid for each cluster in the set of clusters, assigning one of the set of controllers to each network element corresponding to a determined centroid in the graph, and assigning each controller to control a set of network elements corresponding to a cluster in the graph.

Embodiments of the invention include a method performed by a cloud network manager flow entries in a cloud network. The CNM is coupled to virtualized servers for hosting virtual machines ('VM') that each comprise a virtual switch coupled to a top of rack switch ('TORS'). The CNM receives notification messages that indicate virtual machines have been scheduled for activation on virtualized servers. The CNM determines a VM media access control (&#x201c;MAC&#x201d;) address associated with the VM and a virtual switch MAC address associated with that virtualized server's virtual switch. The CNM records an association between the VM MAC address and the virtual switch MAC address. The CNM further determines a label that associates the TORS with the virtual switch. The CNM sends a modifies flow entries in the virtual switch to indicate data packets matching the MPLS label and the VM MAC address should be forwarded to the VM.
