Abstract
Abstract A communications system having a first data subsystem; a data transmission controller coupled to the first data subsystem; a data line coupled to the data transmission controller having a bandwidth with a first portion and a second portion; and, a second data subsystem coupled to the data transmission controller. A method for dynamically estimating and allocating the bandwidth between the first data subsystem and the second data subsystem having the steps of measuring a utilization level of the first portion of the bandwidth by a first application; detecting whether the utilization level is outside of a predetermined range; and, changing an allocation of the first portion and the second portion of the bandwidth.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
99 words
A method for dynamically estimating and allocating a bandwidth having a first portion and a second portion comprising the steps of: measuring a utilization level of said first portion of said bandwidth by a first application by examining an amount of an unused portion of said first portion of said bandwidth; detecting whether said utilization level is outside of a predetermined range and whether a predetermined amount of data generated by said first application has been queued for transmission; and, changing an allocation of said first portion and said second portion of said bandwidth based on said detecting step.
Claim 2
Independent Claim
99 words
A method for dynamically estimating and allocating a bandwidth having a first portion and a second portion comprising the steps of: measuring a utilization level of said first portion of said bandwidth by a first application by examining an amount of an unused portion of said first portion of said bandwidth; detecting whether said utilization level is outside of a predetermined range and whether a predetermined amount of data generated by said first application has been queued for transmission; and, changing an allocation of said first portion and said second portion of said bandwidth based on said detecting step.
