Abstract
A method and apparatus that allows egress pointer smoothing data by evaluating the average fill of an elastic store. For one embodiment of the invention, by measuring the average fill, the 3 bytes of SOH and 87 bytes of data are taken together in each sample, and the relative phase of ingress and egress frames does not impact the fill depth calculation. For one such embodiment, the calculation is performed by summing the elastic store fill over a full row and increment/decrement decisions based on that average figure provide smooth rate of pointers coming out even as a section overhead moves through the frame.
