Shaping self-similar traffic at access of optical network
Performance Evaluation
| Hi-index | 0.00 |
The focus of this paper is the shaping of self-similar traffic at the access of an optical node. We propose a novel algorithm that dynamically shapes the incoming traffic, based on service curves equations, in order to meet the optical nodes 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. We eventually set those parameters back into the original model in order to meet some QoS constraints at the optical network level.
