An apparatus, system, and method for balancing traffic loads on beam outroutes that contain both multicast and unicast traffic. An outroute is designated for supplying at least multicast traffic within a beam of a satellite communication system. Terminals interested in receiving the multicast traffic are moved to the designated outroute. Traffic loads on all outroutes within the beam, including the designated outroute, are compared to determine if variations in the traffic loads exceed a predetermined threshold. A load balancing routine is performed to redistribute the traffic loads on all outroutes, while excluding any terminal that is actively receiving the multicast traffic from the load balancing routine.

Systems and methods of mesh network communication enabling a relay node to autonomously select a packet propagation mechanism. Upon receiving a packet, which may carry an indication for flooding propagation as set by the edge node originating the packet, or carry no specification for any propagation mode, the relay node determines whether the packet is eligible for routing-propagation based on a number of factors, such as whether there is an existent valid route from the source node to the destination node, whether the packet is originated from a friend edge node, and whether a route discovery process has been initiated. Accordingly, the relay node may change the indication to routing propagation and forward it by routing-relaying. Thus, the packet can be propagated over the mesh network by routing propagation, despite the initial setting for flooding propagation as specified by the edge node or no setting by the edge node.

A system for processing messages of a high rate data stream and an apparatus including: a message processor including a plurality of processor sub-modules and configured to read an input data stream, process the input data stream, and to output an output data stream; at least one payload memory storing data related to the input data stream and accessible to the message processor; at least one instruction memory accessible to the message processor and storing computer program instructions configuring the message processor to process the input data stream; and an application processor configured to rewrite the at least one instruction memory.

A system for multicast packet management in a first switch in an overlay tunnel fabric is provided. The system can operate the first switch as part of a virtual switch in conjunction with a second switch of the fabric. The virtual switch can operate as a gateway for the fabric. During operation, the system can receive a join request for a multicast group. The system can then determine whether to forward the join request to the second switch based on a type of a first ingress connection of the join request. Upon receiving a data packet for the multicast group, the system can determine how to forward the data packet based on respective types of a second ingress connection and an egress connection of the data packet. The type of a respective connection can indicate whether the connection includes an overlay tunnel.

Systems and methods associated with a node in a Segment Routing network include, responsive to what services are support at a node in a Segment Routing network, creating a bitmap to represent the plurality of services supported at the node; and transmitting an advertisement with the bitmap such that the advertisement is a single advertisement of multiple services. This approach can reduce the advertisement of rout updates by orders of magnitude.

A wireless communication device includes a processor that generates a packet and a transmitter that wirelessly transmits the packet generated by the processor. The processor is configured to generate a packet containing data destined for a plurality of nodes and set a destination address different from respective addresses of the plurality of nodes in the generated packet, the destination address specifying that the packet is destined for the plurality of nodes.

Some embodiments provide a set of one or more network controllers that communicates with a wide range of devices, ranging from switches to appliances such as firewalls, load balancers, etc. The set of network controllers communicates with such devices to connect them to its managed virtual networks. The set of network controllers can define each virtual network through software switches and/or software appliances. To extend the control beyond software network elements, some embodiments implement a database server on each dedicated hardware. The set of network controllers accesses the database server to send management data. The hardware then translates the management data to connect to a managed virtual network.
