Equation-Based Dynamic Shaping Algorithm

The focus of this paper is the traffic shaping at the access of an network node. We propose a novel algorithm that dynamically shapes the incoming traffic, based on service curves equations, in order to meet the QoS constraints in terms of buffer size or delay. We first estimate arrival parameters within various time intervals in order to make the incoming traffic fit into a token bucket traffic specification (Tspec) format. We then derive the shaping parameters based on deterministic service curves. Those shaping parameters vary dynamically according to the Tspec of every time window.
