摘要： Methods, systems and computer program products for controlling scheduling in an ATM node in a network are provided which aggregate connection information for connections to the ATM node to provide a set of aggregate connection information for the ATM node. The set of aggregate connection information is distributed to other ATM nodes in the network and may be used in accepting connections to the ATM network based on the aggregate connection information. Scheduling may be provided by associating a timestamp value in each cell associated with an accepted connection as it is received by the ATM node. Received cells are grouped into a plurality of cell groups in timestamp order based upon characteristics of the cells and cells are selected from each group so as to transmit the cells in earliest deadline first order.

摘要： A method for protecting data for access by a plurality of users. A server encrypts data using a master key and a symmetric encryption algorithm. For each authorized user, a key encryption key (KEK) is derived from a passphrase, and the master key is encrypted using the KEK. The server posts the encrypted data and an ancillary file that includes, for each user, a user identifier and the master key encrypted according to the user's KEK. To access the data, a user enters the passphrase into a client, which re-derives the user's KEK, and finds, in the ancillary file, the master key encrypted using the user's KEK. The client decrypts the master key and then decrypts the data. A KEK may be derived from a natural language passphrase by hashing the passphrase, concatenating the result and a predetermined text, hashing the concatenation, and truncating.
