摘要： A data-leakage prevention capability is presented herein. The data-leakage prevention capability prevents leakage of data, of a file set having a plurality of files, from a secure network using online fingerprint checking of data flows at a boundary of the secure network. The online fingerprint checking is performed using a set of data structures configured for the file set. The data structures for the file set are configured based on file set characteristics information of the file set and a target detection lag indicative of a maximum number of bits within which a data leakage event for the file set is to be determined. The data structure configuration is computed for a plurality of data structures configured for use in monitoring the files of the file set. The data structure configuration includes a plurality of data structure locations and data structure sizes for the respective plurality of data structures.

摘要： 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.

摘要： A line-rate, real-time-traffic detector classifies a network traffic flow as real-time when it determines the smoothness of the packet arrival rate of the network traffic flow is bounded by an empirically derived bound. In some embodiments, to improve performance, a tighter smoothness bound is applied to the smoothness calculations performed on a first set of packet arrival times, while a looser smoothness bound is applied to a second set of packet arrival times, the second set inclusive of and larger than the first.

摘要： 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.

摘要： The SoftRouter architecture separates the implementation of control plane functions from packet forwarding functions. In this architecture, all control plane functions are implemented on general purpose servers called the control elements (CEs) that may be multiple hops away from the forwarding elements (FEs). A network element (NE) or a router is formed using dynamic binding between the CEs and the FEs. The flexibility of the SoftRouter architecture over conventional routers with collocated and tightly integrated control and forwarding functions results in increased reliability, increased scalability, increased security, ease of adding new functionality, and decreased cost.

摘要： A method of estimating per-flow traffic in a network of nodes interconnected by links samples an incoming traffic stream to a node. A sampling interval is derived based on a desired level of accuracy. The number of two-run occurrences for each flow is tracked in the sample stream. The number of two-runs per flow is then employed to generate an estimate of the traffic of the flow.
