Briefly, methods and/or apparatuses of virtual deployment of network-related features are disclosed.

The disclosure describes techniques for enhancements to the Multicast Source Discovery Protocol (MSDP) to reduce Source Active (SA) message loops in one or more multicast domains having overlapping MSDP mesh groups. In some examples, a method includes receiving, by a first MSDP speaker, from a second MSDP speaker, a SA message. The method also includes, when the second MSDP speaker is in a mesh group with the first MSDP speaker, determining whether the first MSDP speaker includes an active SA state corresponding to the SA message. Additionally, the method includes, when the first MSDP speaker does not include the active SA state corresponding to the SA message, accepting the SA message and forwarding the SA message to a third MSDP speaker that is not in the mesh group with the first MSDP speaker and the second MSDP speaker.

A method for reverse path forwarding (RPF) selection by a network device connected to a network includes receiving an advertisement message from each of a plurality of neighbor devices within the network, parsing the advertisement message to determine a color identification (ID) of each of the neighbor devices, and selecting, from among the neighbor devices, a RPF device based on the color ID of each of the neighbor devices.

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.

A method is disclosed. The method includes: a) receiving node identifiers from nodes of a plurality of nodes in a computer network; b) determining a plurality of node committees in a sampler graph comprising a plurality of nodes, wherein the node is present in a node committee in the plurality of node committees; c) and i) generating a random string; ii) performing a proof of work process using the random string and a hash function; iii) if the proof of work process yields a solution that is acceptable, then broadcasting the solution to all other nodes in the plurality of nodes, wherein the other nodes verify the solution; and iv) if the other nodes verify the solution, the node is elected to a subcommittee for the node committee, wherein the subcommittee updates the sampler graph; and d) repeating steps b) and c) until a leader committee is determined.

A method and device for transmitting or receiving a broadcast signal are discussed. The method for transmitting the broadcast signal can include processing one or more Internet Protocol (IP) packets into link layer packets, processing the link layer packets to output the broadcast signal, and transmitting the broadcast signal. The one or more IP packets can carry components of a service and service signaling information for signaling the components of the service. The broadcast signal can further include a service list table. The service list table can include one or more of service identification information for identifying the service, capabilities information related to the service, channel number information of the service, category information for indicating a type of the service, protocol information for representing a type of a protocol used to deliver the service signaling information.

Some embodiments provide a method of replicating messages for a logical network. At a particular tunnel endpoint in a particular datacenter, the method receives a message to be replicated to members of a replication group. The method replicates the message to a set of tunnel endpoints of the replication group located in a same segment of the particular datacenter as the particular tunnel endpoint. The method replicates the message to a first set of proxy endpoints of the replication group, each of which is located in a different segment of the particular datacenter and for replicating the message to tunnel endpoints located in its respective segment of the particular datacenter. The method replicates the message to a second set of proxy endpoints of the replication group, each of which is located in a different datacenter and for replicating the message to tunnel endpoints located in its respective datacenter.

The subject technology determines, by at least one processor, that a value of a capability parameter is not available for a first recipient device, the first recipient device being one of a plurality of recipient devices. The subject technology receives, from the first recipient device, a value of the capability parameter. The subject technology clusters, by at least one processor, the plurality of recipient devices into a plurality of groups of recipient devices based on device capabilities including an available storage space. The subject technology determines, for each group of recipient devices, a set of content parameters compatible with device capabilities of the plurality of recipient devices of a group of client devices. The subject technology generates, for each group of recipient devices, a version of content according to an associated set of content parameters.

A media system includes a computer network, a media device supporting a network-based media sharing protocol, a plurality of output devices located at a plurality of physical locations within a hospitality establishment, and a system controller. In response to a first event, the system controller assigns the media device to a particular guest device by reconfiguring one or more components of the computer network to enable the particular guest device to utilize the network-based media sharing protocol to share media over the computer network with the media device, and commands an output device located at a physical location associated with the particular guest device to play media corresponding to the media signal outputted by the media device on the output port. In response to a second event, the system controller un-assigns the media device from the particular guest device and commands the output device to stop playing the media.
