Abstract:
Techniques for bridging communication between multiple networks to facilitate distribution of multicast data are described herein. For example, the techniques may identify a particular node that is able to communicate with each network and instruct the particular node to act as a bridge between the networks. The particular node may forward data from either network to the other network. This may allow data for a multicast group to be distributed to members of the multicast group that are located in separate networks.
Abstract:
A method performed by a method performed by a network node for transmitting a message in a mesh network to a destination node is provided. The network node transmits (503) the message addressing the destination node. During a first time interval, the network node scans (504) if any message considered to be a relayed copy of the transmitted message is received. When no message considered to be a relayed copy of the transmitted message is received during the first time interval, the network node repeats the transmitting (505) of the message addressing the destination node. When a message considered to be a relayed copy of the transmitted message is received, the network node decides (506) to not repeat to transmit the message addressing the destination node.

Abstract:
The virtual broadcast system of the present invention optimizes the routing of digital content among nodes along overlay networks that are dynamically reconfigured based upon forecasts of frequently-changing congestion levels of component interconnections within an underlying network. In the context of delivering streaming video over the Internet to large numbers of concurrent users, the present invention makes efficient use of the limited capacity of congested ASN peering points by employing deep learning techniques to forecast congestion levels across those ASN peering points and, based on those forecasts, to optimize the routing of video content along dynamically reconfigured overlay networks. The virtual broadcast system handles unscheduled as well as scheduled events, streams live as well as pre-recorded events, and streams those events in real time with minimal delay in a highly scalable fashion that maintains a consistent QoE among large numbers of concurrent viewers.

Abstract:
A novel method that uses the source port field in the transport or connection layer (L4) header to encode control plane information is provided. Specifically, the method encodes control plane information in UDP or TCP source port field of data plane tunnels in an overlay network such as VXLAN. Network virtualization is implemented by a network controller over an overlay network on the physical fabric. The network controller provides a mapping table to the data plane hosts for mapping the encoded bits in the source port field to semantically richer information. The data plane hosts in turn uses the encoded source bits and the mapping table to infer this semantically richer information. This semantically richer information is used to allow receivers of proxied traffic to learn the address of the original sender. The semantically richer information can also be used to enable ECMP for the transmitted packets.
Abstract:
A controller, which manages nodes that provide virtual entities, receives information from a first of the nodes, where the received information relates to a characteristic of a virtual entity provided by the first node. The controller determines that the received information is inconsistent with information, maintained by the controller, relating to the characteristic of the virtual entity provided by the first node. In response to the determining, the controller reconciles an inconsistency between the received information and the information maintained by the controller.
