Abstract: Techniques and architecture are described for tracking flows of packets in a network using a packet color marking scheme for obtaining network end-to-end traffic flow metrics in the network. In particular, in configurations, a user may be prompted to specify a site and a virtual private network (VPN) at which to start a trace for packet flows using a coloring marking scheme within the network. Given the VPN and the site, it is possible to monitor interested packet flows and apply metadata, e.g., colors, on flow packets. Remote wide area network (e.g., software defined WAN (SD-WAN)) routers receiving the packets with metadata may automatically trace the same flow and apply the same metadata to a next hop router. Hence, an end-to-end network path may be discovered.

Abstract: A computer-implemented method, system and computer program product for improving understandability of text by a user. A final word vector for each word in a sentence of a document is computed, such as by averaging a first word vector and a second word vector for that word. Furthermore, elements of a user portrait are vectorized. A distance is then computed between a vector for each word in the sentence and a vectorized element in the user's portrait which is summed to form an evaluation result for the element. An evaluation result is also formed for every other element in the user's portrait by performing such a computation step. A “final evaluation result” is then generated corresponding to the evaluation results for every element in the user's portrait. The document is then transformed in response to the final evaluation result indicating a lack of understanding of the sentence by the user.
