摘要： Physical connectivity is determined between elements such as switches and routers in a multiple subnet communication network. Each element has one or more interfaces each of which is physically linked with an interface of another network element. Address sets are generated for each interface of the network elements, wherein members of a given address set correspond to network elements that can be reached from the corresponding interface for which the given address set was generated. The members of first address sets generated for corresponding interfaces of a given network element, are compared with the members of second address sets generated for corresponding interfaces of network elements other than the given element. A set of candidate connections between an interface of the given network element and one or more interfaces of other network elements, are determined. If more than one candidate connection is determined, connections with network elements that are in the same subnet as the given network element are eliminated from the set.

摘要： The present invention provides a method and system for sequential pattern mining with a given constraint. A Regular Expression (RE) is used for identifying the family of interesting frequent patterns. A family of methods that enforce the RE constraint to different degrees within the generating and pruning of candidate patterns during the mining process is utilized. This is accomplished by employing different relaxations of the RE constraint in the mining loop. Those sequences which satisfy the given constraint are thus identified most expeditiously.

摘要： In a server system having a predetermined total bandwidth providing data files to a plurality of clients in response to requests received from the clients, a method for providing admission control comprises the steps of allocating a plurality of channel partitions to a plurality of channel groups such that each channel group includes one or more of the channel partitions. The system then obtains a channel group number based on the length of the data file requested by one of the clients and transmits the requested data file when a channel group corresponding to the obtained channel group number contains a vacant channel partition.
