  • Patent number: 9742680
    Abstract: Disclosed herein are methods and calculators for configuring traffic allocations for service classes with different Quality of Service (QoS) in a router. Example embodiments involve setting allocations at a router based on traffic rate values and/or traffic weight values provided by a user. The router may monitor actual traffic rates to ensure that traffic is not being dropped due to improper rate allocations and to provide historical data for optimizing traffic allocations. In addition, the router may automatically adjust traffic allocations to avoid dropping high(er) priority traffic. The router may also transmit alarms to the user and/or to other network devices to prompt traffic re-routing and/or re-allocation of traffic rates. Example methods and apparatus ensure appropriate traffic allocation to meet certain QoS metrics.
