Abstract: 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.

Abstract: Various embodiments provide a method and apparatus of providing a distributed network file system in a cloud network that provides performance guarantees in cloud storage that are independent of the accessed files and the access locations. A client's file system is provisioned using a file placement strategy that is based on client's access locations and determined maximum access bandwidths and does not require knowledge of file access patterns.

Abstract: A distribution and scheduling system for advertisements that targets ads to users and maximizes service-provider revenue without having full knowledge of user-profile information. Each user device stores a user profile and is pre-loaded with a set of ads that could possibly be shown during a timeslot. Each user device selects and displays an ad based on the user profile but does not identify the selected ad to the service provider. Instead, the user devices provide perturbed user-profile information in the form of Boolean vectors, which the service provider uses in conjunction with a guaranteed-approximation online algorithm to estimate the number of users that saw a particular ad. Thus, the service provider can charge advertisers for the number of times their ads are viewed, without knowing the users' profiles or which ads were viewed by individual users, and users can view the targeted ads while maintaining privacy from the service provider.

Abstract: In one embodiment, a method for estimating the number of tags in a set of tags in a system of tags and readers. The method includes, during each of a plurality of time intervals: (i) transmitting a command requesting that each tag that receives the command determine whether to transmit a reply; and (ii) receiving, in one or more timeslots of a frame corresponding to the time interval, replies from one or more tags. The method further includes providing an estimate of the number of tags in the set of one or more tags based on (i) timeslots in each of the plurality of time intervals that are zero timeslots, i.e., timeslots having no received reply, and (ii) the total number of timeslots in each frame.

Abstract: In one embodiment, a scheme for the display of targeted and personalized advertisements in a packet-based media-delivery system, such as an Internet Protocol Television (IPTV) service. An Internet keyword-based advertisement-bidding model is used to place the most-appropriate IPTV advertisements for viewers depending on their interests as determined through the users' Internet activities, while maximizing advertising revenue for the IPTV service provider. One method for scheduling an advertisement for rendering in one or more time slots in packet-based media programming comprises: (a) obtaining at least one keyword from one or more Internet sessions corresponding to at least one user; (b) receiving a plurality of bid amounts corresponding to a plurality of available advertisements for the one or more time slots; and (c) scheduling, based on the at least one keyword and at least one of the bid amounts, the advertisement to be rendered to the at least one user in the one or more time slots.

Abstract: 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.

Abstract: In one embodiment, a method for supporting recovery from failure of a path in a network of nodes interconnected by links. An intermediate node between an ingress point and an egress point of the network is selected to minimize the sum of (i) a capacity constraint between the ingress point and the intermediate node and (ii) a capacity constraint between the intermediate node and the egress point. The selection identifies two link-disjoint path sets, each comprising a backup path and at least one primary path, with a first path set between the ingress point and the intermediate node, and a second path set between the intermediate node and the egress point. To maximize network throughput, packets are routed in two phases, first to the intermediate node via the first path set in predetermined proportions, and then from the intermediate node to the final destination via the second path set.

Abstract: In one embodiment, IP lookup into a routing table having prefixes of different prefix lengths is performed using a Bloom filter that was programmed with the prefixes corresponding to all of the different prefix lengths without having to expand any of the prefixes programmed into the Bloom filter. Membership probes are performed into the Bloom filter using candidate prefix values of a given network address. The Bloom filter can be implemented in a distributed manner using Bloom sub-filters, where each Bloom sub-filter is hashed based on a set of hash functions, where each different hash function in the set corresponds to a different prefix length in the routing table. Each Bloom sub-filter can in turn be implemented using a plurality of practically realizable multi-port memory devices controlled by a port scheduler. False-positive matches can be detected and next-hop information for true-positive matches retrieved using an off-chip, hash-based prefix table.

Abstract: 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.
