1. A method of managing an allocation of a bandwidth of a dedicated channel in a network being utilized by an application performing a replication of data from a first storage resource to a second storage resource, the method comprising:

  • determining checks of parameters specified by the application, the parameters including an average compression ratio of the data over a first amount of time, a trend of the average compression ratio of the data, an average throughput over a second amount of time, a trend of the average throughput, and a round trip time of the data in the replication being sent from the first storage resource to the second storage resource;

    determining respective high and low threshold values for the parameters of at least one of the checks of parameters;

    executing the at least one of the checks of the parameters during the replication of data from the first storage resource to the second storage resource, the executing determining a violation of a high or low threshold value during the replication for one parameter of the parameters of the at least one of the checks of parameters; and

    based on determining the violation of the high threshold value, triggering, during the replication an increase in the bandwidth, the increase being a first specified amount associated with the high threshold value, or based on determining the violation of the low threshold value, triggering, during the replication, a decrease in the bandwidth, the decrease being a second specified amount associated with the low threshold value.
