US Classification:
380 2, 713162, 726 26
Abstract:
Presented is a method for determining the maximum number of key selection vectors (KSVs) supported by an HDCP source. The method includes transmitting a number of KSVs to the HDCP source, determining whether the HDCP source has entered a failure mode in response to the transmitted number of KSVs, increasing or decreasing the number of KSVs in response to the HDCP source not entering or entering the failure mode, transmitting the increased or decreased number of KSVs to the HDCP source, determining whether the HDCP source has entered the failure mode in response to the transmitted increased or decreased number of KSVs, and repeating the increasing, decreasing, and determining steps until the difference between a lowest number of transmitted KSVs resulting in the HDCP source entering the failure mode and a highest number of transmitted KSVs resulting in the HDCP source not entering the failure mode is one.

International Classification:
G06N 5/04
US Classification:
706 46
Abstract:
A method (which can be computer implemented) fox inferring component associations among a plurality of components in a distributed computing system includes the steps of obtaining status information fox each pertinent component of the plurality of components, forming an N by D matrix, X, based on the status information, and factorizing the matrix X to obtain a first matrix indicative of the component associations to be inferred and a second matrix indicative of failure explanations for corresponding ones of the probe instances. N is a number of probe instances associated with a given time flame. D is a number of the plurality of components fox which the associations are to be inferred. Techniques are also presented for forming a database with the status information.

G06F 15/173
US Classification:
707792, 707812, 709223, 707E17045, 707E17005
Abstract:
In one embodiment, the disclosed technology involves modeling network elements, such as router configurations and link information, as well as any generic network status, as data in a relational database. Various network data, such as router states and link states are abstracted into tables in the relational database. Network management operations may then be represented as a series of transactional database queries and insertions. As a result, the database automatically propagates, to the appropriate network elements, state changes that are written to database tables, thereby implementing various network operations. Tables in the database can be constructed at various levels of abstraction, as required to satisfy network operational demands. Programmability is provided by a declarative language composed of a series of database queries and insertions.

G06F 15/177
US Classification:
707812, 709221, 707E17045
Abstract:
The disclosed technology involves the use of relational databases in conjunction with declarative language and network-wide, database abstractions to manage and operate networks. The data model creates a logically centralized database abstraction and access point for managing data relevant to network management. Exemplary managed data includes router configurations, network status and provisioning data. This information resides in a single database system which is tightly integrated with the operational network. Transactional write operations are used to change network configurations, and enforce constraints to detect and prevent policy violations during operation. In accordance with one aspect of the disclosed technology, a network operation is implemented by means of a series of database commands—read and/or write—from and to database view tables.

International Classification:
G06F 17/30
US Classification:
707803, 707E17044
Abstract:
An aspect of the disclosed technology is a general-purpose platform that may be used to provide resilient cloud services. Tasks may be written as procedures in general-purpose programming languages that directly manipulate resources via control interfaces. In one implementation, resource states, such as router configurations and virtual machine states, associated with a cloud customer that provides communications services, may be abstracted into tables in a relational or semi-structured database. State changes that have been written to the database tables are automatically propagated by the database to appropriate customer physical devices, such as network elements, thereby implementing various customer network operations.
