Abstract:
1. A method comprising: receiving at an ingress device a request for admission of a new communications flow comprising a plurality of packets from the ingress device into a network having a stable state and an unstable state; determining coefficients for a polynomial representing a state of the network, the coefficients for the polynomial based at least in part on data for packets entering the network from the ingress device and exiting the network at an egress device; applying the polynomial with the coefficients to the new communications flow to determine whether admission of the new communications flow into the network would cause the network to operate in the stable state or the unstable state; and downgrading a quality of service of at least one communications flow for the ingress device in response to determining that the network is operating in the unstable state in response to introduction of the new communications flow.
