Abstract: Server computers of card issuer-processors can determine a mapping of dependencies of a plurality of components of a card processing protocol and create groups of components that can be executed in parallel. The groups of the components are sequentially processed within a limited time period.

Abstract: A multicast system includes a source device and a plurality of receiver devices connected by switches that are also coupled to a switch controller. The switch controller receives source device information for the source device from its connected first switch, and receives receiver device information for each of the receiver devices from their respective connected second switches. The switch controller uses the source device information and receiver device information to construct a multicast tree that includes switches capable of transmitting multicast communications from the source device to each of the receiver devices. The switch controller then programs at least some of the switches so that a multicast data communication from the source device is segment routed to a third switch, and replicated by the third switch to produce replicated multicast data communications that are each segment routed to at least some of the receiver devices through their respective second switches.

Abstract: An inter-datacenter multicast system includes a first datacenter connected to a second datacenter. A first multicast router device is located in the first datacenter and includes at least one first multicast router interface that provides a link to the second datacenter, and a second multicast router device is located in the second datacenter and includes at least one second multicast router interface that provides a link to the first datacenter. The first multicast router device and the second multicast router device sync multicast routes with each other to enable each to act as respective designated routers, and also each remove multicast router interfaces that provides links to the other datacenter from outgoing interface Virtual Local Area Networks (VLANs) that are part of a multicast route, which prevents traffic tromboning and reduces multicast data communications between the first datacenter and the second datacenter.
