Abstract: Embodiments are disclosed in which a process receives annotation inputs for annotations of a document. The annotation inputs may be grouped together into clusters based at least in part on a functional relationship between the timing of annotation inputs and the paths of the annotation inputs across an electronic display. The annotation inputs may be associated with portions of the document based at least in part on the shape of the paths of the annotation inputs, the sequence of annotation inputs, or the locations of the annotation inputs. Additionally, the paths of the annotation inputs to portions of the document may be modified in response to modifications of the portion of the document data.

Abstract: A method for building a network route map is described in which network operational characteristics are gathered by actively probing multiple network routes, and building the network route map based on the operational characteristics. Route maps are generated which provide a view of the network from the perspective of a particular routing device in the network. Embodiments include methods for gathering the operational data by transmitting one or more data packets, receiving responses thereto, and determining time differentials based on the responses. Other embodiments include methods for processing the operational data to determine various metrics, and normalizing the data with similar data gathered from other network route probes. Finally, additional embodiments include propagation of the preferred route information to multiple routing devices to provide intelligent route selection thereto.
