摘要： In one embodiment, a method for estimating the cardinality of one or more tags in a system that has the one or more tags and one or more readers. The reader issues a command requesting that the tags identify themselves. The command includes timing information defining a total number of timeslots. In response to the command, each of the one or more tags (i) selects a timeslot in which to reply to the command and (ii) issues a reply in the selected timeslot. The method includes: (a) issuing the command; (b) receiving, in one or more timeslots, replies from the one or more tags; and (c) deriving an estimate of the cardinality of the one or more tags in the system based on at least one of: (i) the number of zero slots, wherein a zero slot is a timeslot that has no tags transmitting therein, (ii) the number of singleton slots, wherein a singleton slot is a timeslot that has only one tag transmitting therein, and (iii) the number of collision slots, wherein a collision slot is a timeslot that has more than one tag transmitting therein.

摘要： Apparatuses, methods and articles of manufacture for performing data leakage prevention are provided. Data leakage prevention may be performed by determining a signature of a transmitted document, the transmitted document being in transit to a location beyond a network boundary. The signature of the transmitted document is compared with one or more signatures of documents authorized to be transmitted beyond the network boundary. The transmitted document is prevented from being transmitted beyond the network boundary if the signature of the document does not correspond to a signature of a document authorized to be transmitted beyond the network boundary.

摘要： A data block storage management capability is presented. A cloud file system management capability manages storage of data blocks of a file system across multiple cloud storage services (e.g., including determining, for each data block to be stored, a storage location and a storage duration for the data block). A cloud file system management capability manages movement of data blocks of a file system between storage volumes of cloud storage services. A cloud file system management capability provides a probabilistic eviction scheme for evicting data blocks from storage volumes of cloud storage services in advance of storage deadlines by which the data blocks are to be removed from the storage volumes. A cloud file system management capability enables dynamic adaptation of the storage volume sizes of the storage volumes of the cloud storage services.

摘要： In one embodiment, a method for supporting recovery from failure of a node in a network of nodes interconnected by links A set of two or more intermediate nodes (excluding the failed node) between an ingress point and an egress point is selected. Next, based on available bandwidth of the network, a non-zero fraction of the service level to route from the ingress point to each intermediate node is determined. Packets are then routed in two phases by: (1) determining one or more paths from the ingress point to each intermediate node for routing the corresponding fraction of the service level, and (2) determining one or more paths from each intermediate node to the egress point for routing the corresponding fraction of the service level.

摘要： In one embodiment, IP lookup into a routing table having prefixes of different prefix lengths is performed by hashing a candidate prefix value to generate a plurality of hash values, where m seed hash values are generated by applying m seed hash functions and one or more additional hash values are generated by combining two or more of the seed hash values in different ways, e.g., using a bit-wise XOR function. The hash values are used to perform membership probes into a Bloom filter programmed with the prefixes corresponding to all of the different prefix lengths in the routing table without having to expand any of the prefixes programmed into the Bloom filter.

摘要： In one embodiment, a wireless-resource broker employs a self-enforcing spectrum-sharing policy, e.g., the expected utility (e.g., rate) a user obtains by following the policy provided by the broker is not less than the expected utility that the user obtains by switching to some other strategy. Each user is associated with one or more transmitter-receiver pairs, e.g., a transmitter of a wireless device and a receiver of a base station in communication via a wireless channel. The broker receives, as input, user parameters characterizing one or more of the transmitters and/or receivers and resource parameters characterizing one or more available spectrum blocks. The broker solves a linear-programming problem to generate and transmit a recommended policy for one or more users. The policy for each user includes information such as the spectrum block(s) to which the user is assigned, the transmission power for the user, and the transmission rate for the user.

摘要： A network of nodes interconnected by links, such as a wavelength division multiplexing (WDM) ring network, is modeled by a delayed graph in which propagation delay between nodes is accounted for. Given the delayed graph, a traffic matrix for an admissible traffic pattern is scheduled over a frame period. Scheduling of the traffic matrix formulates a set of scheduling constraints based on the delays and decomposes the traffic matrix into a set of transmission matrices. Each of the set of transmission matrices is scheduled over the frame period.
