摘要： A high level of security is realized by imposing limitations on an unauthorized communications device in establishing connection to a network, without involvement of an increase in the burden of network equipment such as a router or a communications device constituting a network. An address delivery section 103 in a router 101 delivers a link local address in answer to an address request from a communications device 111, and requests the communications device 111 to transmit authentication data. An equipment authentication section 102 in the router 101 authenticates the communications device 111 on the basis of the authentication data transmitted from the communications device 111, and reports an authentication result to the address delivery section 103. When the communications device 111 has been authenticated, the address delivery section 103 delivers a global address or a site local address to the communications device 111.

摘要： A method is provided for mobile wireless ad hoc network, where network nodes using the same routing protocol are uniformly sharing a single contention channel. Network nodes are able to dynamically and distributedly switch roles according to surrounding network environment so that routing functions can be either activated or de-activated in order to improve routing efficiency and increase network capacity by reducing unnecessary routing overhead (which is caused by excessive redundant routing nodes). In addition, the nodes are able to self organize themselves into hierarchies or different roles according to different routing strategies. The proposed role-switching method can be implemented on network nodes which support existing routing protocols or native routing protocol proposed herein to further exploit the proposed role-switching method.

摘要： Improved algorithms are provided for performing path management for a plurality of select data transmission sessions in a multicast network.

摘要： When a transport rate Rs is updated, in the case where the updated transport rate Rs is within a variable range (Rc 1) defined by a current encoding rate Rc, FEC (Forward Error Correction) data sending rate Rf is updated (Rf=Rs−Rc) without updating the current encoding rate Rc. On the other hand, in the case where an Rc update timer set to three seconds, for example, is timed out, the encoding rate Rc is updated using a minimum value Rs_min of the transport rate up to that time (Rc=V×Rs_min, and 0

摘要： A method is provided for selecting a route for transmitting data packets amongst nodes in an ad hoc network. The method includes determining a metric which is indicative of link stability between the nodes in the network; initiating a route discovery procedure that generates a plurality of candidate transmission paths between a source node and a destination node; and selecting a transmission path from amongst the plurality of candidate paths using the metric for nodes associated with each candidate path. The metric may be further defined as link duration (i.e., an amount of time the node maintains a link with neighboring nodes link duration).

摘要： A multicasting network route provisioning system for use in allowing an in-session multicast application to switch its path on need includes a datastore of multicast addresses operable to route multicasting traffic over different network paths. It also includes a datastore of multicasting sessions having flows of various flow patterns, wherein a flow pattern is defined in terms of a set of source and destination network nodes, and corresponds to multiple routing network paths. Further, a session management module is adapted to aggregate multicasting session flows by allocating multicast addresses to multicasting sessions based on correspondence between the network paths and flow patterns of the multicasting sessions, thereby ensuring that flow patterns corresponding to different sets of network paths do not share a same multicast address.
