Abstract:
1. A method for setting a threshold in a passive optical network that includes an optical line terminal (OLT) and a plurality of optical network units (ONUs), the OLT granting grants to the ONUs, the ONUs transmitting packets arranged in sub-queues in response to the grants, the method comprising the steps of: a. performing a comparison between parameters reported by one of the ONUs and a desired grant length; and b. adjusting a common threshold value of all the sub-queues of a first ONU based on the results of said comparison; wherein said parameters include a reported total bytes parameter; wherein said step of performing a comparison includes summing values of said reported total bytes parameter for all sub-queues of the first ONU to obtain a total bytes sum, and, if said total bytes sum is larger than said desired grant length, summing values of a reported bytes below a threshold of each sub-queue of the first ONU to obtain a bytes below threshold sum; and wherein said step of performing a comparison further includes comparing said bytes below threshold sum to said desired grant length, and wherein said step of adjusting said common threshold value includes decreasing said common threshold value if said bytes below threshold sum is larger than said desired grant length.
