A network system includes: a VXLAN region that is connected to a vEPC virtual network and in which encapsulation by VXLAN is performed; a PBB region in which encapsulation by PBB is performed; an edge router that belongs to the VXLAN region and is connected to an edge switch in the PBB region; and an edge switch that belongs to the PBB region and is connected to the edge router. The edge router performs conversion between a VNID of data encapsulated by the VXLAN and an intermediate CVID of decapsulated data exchanged with the edge switch, and the edge switch performs conversion between an ISID of data encapsulated by the PBB and the intermediate CVID.

A communication device adapted for communicating in a communication system can include a receiver, a processor, and a transmitter. The receiver can receive (e.g., capture, sniff) information from one or more wireless devices (e.g., vehicles) using a first communication technology (e.g., V2X technologies). The processor can process the received information to generate system information associated with the communication system. The transmitter can transmit the system information to one or more wireless devices using a second communication technology (e.g., LTE) different from the first communication technology.

A method includes identifying within a network topology, by an apparatus, a plurality of network devices; and establishing by the apparatus, a multiple tree topology comprising a first multicast tree and a second multicast tree, the first and second multicast trees operable as redundant trees for multicast traffic in the network topology, the establishing including: allocating a first of the network devices as a corresponding root of the first multicast tree, allocating a first group of intermediate devices from the network devices as first forwarding devices in the first multicast tree, allocating a second group of intermediate devices as belonging to first leaf devices in the first multicast tree, and allocating terminal devices of the network devices as belonging to the first leaf devices, and allocating a second of the network devices as the corresponding root of the second multicast tree, allocating the second group of intermediate devices as second forwarding devices in the second multicast tree, allocating the first group of intermediate devices as belonging to second leaf devices in the second multicast tree, and allocating the terminal devices as belonging to the second leaf devices.

A centralized communication system is disclosed that provides a modular, extendible, and scalable communication system that can exchange information between any information systems or networked devices. Adapter interfaces are configured to adapt message communications between at least one medical device and at least one external device, and graphic interface for control and modification of a communication topology of the centralized communication system is displayed, a first user selection a respective representation corresponding to the first adapter interface is received, and one or more first controls configured to cause a display of the routing information associated with the first device and to modify communication between the first adapter interface and the first device are provided responsive to the first user selection.

A centralized communication system is disclosed that provides a modular, extendible, and scalable communication system that can exchange information between any information systems or networked devices. Adapter interfaces are provided to modify message communications between medical systems in a hospital network, and a graphic interface is provided for modification of communication topology information pertaining to the adapter interfaces in the centralized communication system. The graphical interface provides one or more controls configured to modify at least a portion of the communication topology information, and displays an indication of the modification.

Wireless communication devices may directly communicate within groups of wireless communication devices using Layer-2 communications to implement “push-to-talk” type applications. In one implementation, a method may include generating a floor request signaling message to take control of a communication channel for a group. After transmitting data relating to the communications, a floor release signaling message may be generated and transmitted a number of times.

The present invention relates to an apparatus and a method for configuring a control message in a broadcasting system for supporting a multimedia service based on an internet protocol. To this end, control information to be recorded in a payload of a control message to be configured is generated based on a table selected from among a plurality of tables for defining the information related to the generation and consumption of a hybrid content when a message type of the control message to be configured is determined to be a type for providing information related to the generation and consumption of a hybrid content. In addition, the information related to the type of the selected table is recorded in an optional field of the control message to be configured.

The techniques disclosed herein provide a system that can generate targeted positioning of message content for multi-user communication interfaces. In some configurations a system may generate a user interface that displays a number of video stream renderings, wherein individual video stream renderings, e.g., thumbnail views, show a participant of a communication session. When one of the participants sends the user a private message, the system renders at least a portion of the private message in a semi-transparent format as an overlay on the video rendering of the sender. This allows a traditional video stream interface to also function as an organizer for private messages sent to a particular user. This user interface format allows a user to readily identify a broader perspective of chat activity without requiring a user to enter specific chat user interfaces or provide a number of manual input entries to view the private chat content.

A system and method for managing fleets of network MFPs uses a portable data device such as a networked smartphone to discover and query devices over one or more network subnets. The smartphone sends out a multicast device discovery petition to all network devices and processes responses received asynchronously in parallel. A sequence of smaller multicasts can be used so as not to overwhelm available device resources. Once all devices has responded, all responses are checked sequentially. Devices identified as multifunction peripherals are sent a second petition seeking device state information. Received device state information is stored in a management database.
