Preloading token buckets for dynamically implementing speed increases

摘要

Providing a dynamic bandwidth increase using at least one token bucket is disclosed. At least one token bucket is pre-loaded to capacity using PCMM commands to dynamically implement speed increases in the network. By pre-loading the at least one token bucket to capacity, the rate cap assigned to the customer is overridden. When the token bucket is exhausted the customer continues at their provisioned rate cap. Only a configuration file has to be changed to implement the temporary bandwidth increase. The token buckets may be implemented on a per service flow basis. Further, a plurality of token buckets may be provided, wherein a first token bucket is configured to control a total burst size and a second token bucket is configured to control an individual flow burst rate up until the first token bucket is depleted.

1. A policy manager, comprising:
memory for storing data; and a processor, coupled to the memory, the processor configured to implement a single token bucket for a given subscriber having parameters for controlling the amount of data injected into a network, the parameters including a dynamic aperture establishing a rate cap that sets a maximum rate at which tokens are removed from the single token bucket, the processor receiving and processing packet cable multimedia commands to dynamically configure the parameters of the single token bucket to provide a temporary bandwidth increase, the temporary bandwidth increase provided by preloading the single token bucket to capacity.
