Systems and methods for service assurance using virtualized federated presence infrastructure

A computer program product comprising:

• a non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:
• computer readable program code configured to accept query input comprising identification of network connected endpoint devices of a voice over internet protocol network;
• computer readable program code configured to communicate the query input to a virtualized presence server;
• wherein the virtualized presence server employs a hierarchy of query processing cells to implement a scalable virtualization platform;
• each of said query processing cells comprising a virtual presentity defined by a specific membership set, wherein presence status of each of said query processing cells is an aggregation of presence data of individual members of the membership set;
• and
• computer readable program code configured to employ the virtualized presence server to obtain, from one or more presence servers, a resolved network topology of network service flow for the network connected endpoint devices of the query input;
• the resolved network topology including:
• one or more network elements connecting the network connected endpoint devices;
• and
• device-related information relating to the one or more network elements;
• wherein the device related information comprises information regarding a network problem related to the one or more network elements;
• and
• wherein the obtaining of the resolved network topology comprises:
• gathering data from various heterogeneous network data sources;
• the gathered data comprising at least one of:
• network events, call setup/teardown, topology change, event router state;
• transforming the data into presence schemas;
• publishing the data to the one or more presence servers;
• wherein said adapters gather the data in real time as and when one or more data changes relating to one or more network events occur;
• wherein the hierarchy of query processing cells comprises three levels comprising a path stitcher query processing cell, at least one segment resolver query processing cell and neighborhood resolver query processing cells;
• the obtaining of the resolved network topology comprising using the hierarchy of query processing cells to implement topology stitching service logic via:
• using the path stitcher query processing cell to receive a failed call detail record, divide a path corresponding to the failed call detail record into segments and pass on the segments to the at least one segment resolver query processing cell;
• using the at least one the segment resolver query processing cell to resolve the segments, find nodes and find links connecting the nodes;
• using the neighborhood resolver query processing cells to find a next-hop neighboring node for each node;
• and
• using the path stitcher query processing cell to combine the resolved segments to form a resolved path.

An apparatus comprising:

• one or more processors;
• and
• a memory operatively connected to the one or more processors;
• wherein, responsive to execution of computer readable program code accessible to the one or more processors, the one or more processors are configured to:
• accept query input comprising identification of network connected endpoint devices of a voice over internet protocol network;
• communicate the query input to a virtualized presence server;
• wherein the virtualized presence server employs a hierarchy of query processing cells to implement a scalable virtualization platform;
• each of said query processing cells comprising a virtual presentity defined by a specific membership set, wherein presence status of each of said query processing cells is an aggregation of presence data of individual members of the membership set;
• and
• employing the virtualized presence server to obtain, from one or more presence servers, a resolved network topology of network service flow for the network connected endpoint devices of the query input;
• the resolved network topology including:
• one or more network elements connecting the network connected endpoint devices;
• and
• device-related information relating to the one or more network elements;
• wherein the device related information comprises information regarding a network problem related to the one or more network elements;
• and
• wherein the obtaining of the resolved network topology comprises:
• gathering data from various heterogeneous network data sources;
• the gathered data comprising at least one of:
• network events, call setup/teardown, topology change, event router state;
