PROACTIVE HANDLING OF NETWORK FAULTS

摘要

The techniques and/or systems described herein implement a fault handling service that is able to ensure that at least part of a network can avoid congestion (e.g., a link exceeding capacity) as long as a predetermined maximum number of faults is not exceeded. The fault handling service models different combinations of possible faults based on network topology and then computes an amount of traffic to be communicated via individual paths such that congestion is avoided as long as a number of actual faults that occur is less than or equal to the predetermined maximum number of faults.

1. A method comprising:
determining a predetermined maximum number of faults for at least a portion of a network; determining one or more flows of the at least the portion of the network; generating, by one or more hardware processors and based at least in part on the predetermined maximum number of faults, a model of different combinations of one or more faults for the at least part of the network; computing, based at least in part on the model and for individual flows of the one or more flows, an amount of traffic to be communicated via one or more individual paths such that congestion is avoided if a number of actual faults that occur in the at least the portion of the network is less than or equal to the predetermined maximum number of faults; and causing, for individual flows of the one or more flows, traffic to be distributed in the at least the portion of the network based at least in part on the amounts of traffic to be communicated on the one or more individual paths.
