Abstract

A system is proposed herein for autonomous, policy-driven bandwidth scaling of live media flows in Internet Protocol (IP) fabric networks. An ingress switch measures actual flow bitrate against an allocation enforced by a policer and detects sustained deviations. An orchestrator evaluates whether a multicast group is eligible for scaling, checks capacity along the flow path, and coordinates changes to flow policies on affected switches. For a bitrate increase, the system reserves capacity across the path before committing a higher allocation and rejects a request if capacity or policy conditions are not satisfied. For a sustained decrease, the system reduces the provisioned allocation, subject to tolerance and minimum-rate bounds, and returns reclaimed capacity to a shared pool after the path acknowledges the change. Per-group eligibility, priority arbitration, hysteresis, asymmetric detection windows, action limits, and settling intervals bound changes during live operation. When orchestration is unavailable, existing switch policies remain enforced; after reconnection, stored policy intent is reconciled with measured network state.
