A teleconferencing robot for enabling a remote conferee to project a sense of presence into a group meeting. The teleconferencing robot includes: a base; a video monitor movably mounted to the base for receiving and displaying an image of the remote conferee; an attention getting device for getting the attention of conferees in the group meeting; a control device mounted on the base for moving the video monitor and actuating the attention getting device in response to an input control signal derived from a remote signal generated by the remote conferee and sending an outgoing data signal to the remote conferee providing feedback to the remote conferee from the robot; and the video monitor and attention getting device move in response to the input control signal to enable the remote conferee to project a sense of presence into the group meeting, and to confirm the movement by the outgoing data signal.

An approach for establishing secure multicast communication among multiple multicast proxy service nodes is disclosed. The multicast proxy service nodes, which can be distributed throughout an enterprise domain, are organized in a logical tree that mimics the logical tree arrangement of domains in a directory server system. The attributes of the multicast proxy service nodes include the group session key and the private keys of the multicast proxy service nodes that are members of the multicast or broadcast groups. The private keys provide unique identification values for the multicast proxy service nodes, thereby facilitating distribution of such keys. Because keys as well as key version information are housed in the directory, multicast security can be achieved over any number of network domains across the entire enterprise. Key information is stored in, and the logical tree is supported by, a directory service. Replication of the directory accomplishes distribution of keys. Multicast proxy service nodes may obtain current key information from a local copy of the replicated directory.

An approach for establishing secure communication among multiple multicast groups using a multi-master directory is disclosed. The multi-master directory is on a per object and per attribute access controls basis. The event service nodes, which can implemented as event servers, are distributed throughout an enterprise domain. The attributes of the event service nodes include the group session key and the private keys of the event service nodes. A standardized authentication service is used to register publishers and subscribers. These publishers and subscribers can individually belong to multiple multicast groups under a readily scalable, secure network architecture.

The embodiment of the invention discloses a message prompting method, a message display method and relevant devices. If the unviewed message of the messages sent to the user is received in the group session interface, a message prompting identifier can be displayed on the group session interface. If the user wants to view the unviewed message, the message prompting identifier can be unfolded, andthe instant messaging tool unfolds a message viewing area in the partial area of the direct group session interface and displays the unviewed message of the user in the message viewing area. The message viewing area and the group session interface are simultaneously displayed so that the sent and received messages in the group session interface can be viewed without leaving the current group session interface when the user views the message in the message viewing area. Operation can be simplified by the message viewing mode, the user does not need to switch the session interface and the current interactive message in the group session interface is not missed so that the user experience can be enhanced.
