Abstract:
Techniques for utilizing a cloud service to compute an end-to-end SLA-aware path using dynamic software-defined cloud interconnect (SDCI) tunnels between a user device and an access point-of-presence (POP) node and inter-POP tunnels of the SDCI. The cloud service may include a performance aware path instantiation (PAPI) component including a POP database for storing performance metrics associated with the POPs of the SDCI, an enterprise policy database for storing user specific policies, and/or a path computation component. The path computation component may compute the path, based on the user specific policies, performance metrics associated with the POP nodes, and/or real-time contextual data associated with the user device and/or destination device. The path may include a first tunnel between the user device and the most optimal access POP node of the SDCI and a second tunnel between the access POP node, through the internal POP nodes, and to the destination device.
