In one illustrative example, a wireless network device of a low data rate wireless personal area network (WPAN) or the like includes a controller, memory for storing one or more application programs, and a wireless transceiver coupled to the controller and operative for communications in the wireless network. The controller is adapted to receive, through the wireless transceiver, an instruction which causes the wireless device to operate as a client in performing an OAD procedure for receiving the program from another wireless device which is operated as a server in the wireless network, and to operate the wireless device as the client in performing the OAD procedure in response to such instruction. The controller is further adapted to receive, through the wireless transceiver, one or more instructions for the wireless device to operate as a server in performing the OAD procedure for sending the program to one or more other wireless devices which are operated as clients in the wireless network, and to operate the wireless device as the server in performing the OAD procedure in response to such instructions. A, commissioner device of the wireless network may coordinate the assignment of client and server roles of the wireless devices for OAD procedures based on a variety of different heuristic or algorithmic techniques for optimal results.

A system, apparatus, and method are directed to managing multicast routing using a network cluster. A cluster master actively participates in multicast control protocol communications with the cluster neighbors, while non-master member nodes, do not participate in the protocols' operation outside of the cluster. However, each cluster member maintains virtually the same protocol state, such that should the master become unavailable, another cluster member may assume the master role with minimum delay. New members to the cluster are synchronized by receiving initial protocol state information from the master. After the initial protocol state synchronization, cluster members actively monitor the network to acquire new protocol state information. In addition, cluster members exchange protocol state information between themselves that may not be obtainable off the network. Filtering of multicast data packets is performed by each cluster member, to load balance multicast data traffic across the cluster members.

A system and method according to the present invention allow two or more peer-to-peer wireless devices to automatically connect to each other with no knowledge or pre-configuration of client / server roles. According to a first aspect of the present invention, a wireless device performs inquiries at a random interval, and performs an inquiry scan and a page scan when not performing the inquiries. Upon receiving a first device address in response to one of the inquiries, the wireless device performs a first page using the device address to establish a connection. And upon receiving an inquiry during the inquiry scan, the wireless device responds with a second device address, and if a second page is received during the page scan, establishes a connection.

Recovery is provided in a timing network. A configuration is defined for that network, and in that configuration, an active primary server is identified that provides a clock source for the network. Additionally, an alternate server is identified that can perform the role of the active primary server, should the active primary server fail. In response to a failure of the primary server, the alternate server detects the failure and performs takeover of the primary server.

The invention discloses a device, method and system for resolving request conflicts, belonging to the field of conference systems. Aiming at the problems existing in the prior art that the server role must be introduced outside the device, resulting in complex systems, high costs, and external dependence, the present invention generates identity information locally on the device and follows the device, and updates data with each other in real time. On the basis of some interactive collaboration systems, decentralization is realized. When multiple users in the system initiate a lecture request, the present invention does not need to use the server to judge the timing of the request, but uses the information stored locally in each device to determine the request conflict. Judgment, at the same time, the device can judge the optimal device, which solves the conflict problem of multiple members initiating the lecture request in the traditional interactive collaboration system, and does not require third-party devices to participate in logic and timing judgments, reducing operating costs and system complexity.

Provided are approaches for remote managing comprising at least one or more agents being resident in at least one or more management terminals connected to each other through a network and controlling the corresponding management terminals; and a management server transmitting to the agents a request for a service for managing the management terminals, where the management server transmits the request to the agent through a control channel. An independent control channel is formed between a management server and a management device separately from an ordinary communication channel and, in case the management device is required to perform a server role for a particular service, makes the corresponding management device require a request related to the service through a control channel and thus, the server role is assigned to the management server at the time of carrying out a service.
