This paper provides a new methodology to quantify the impact of optical burst reordering in OBS networks on the TCP/IP end-to-end performance. The paper assumes a multi-layer network stack consisting on TCP/IP on top of OBS. It proposes a multi-layer analysis of burst and packet reordering that is realized by simulation. The paper applies the packet reordering definition of the IETF IPPM working group and use two different reorder metrics for precise characterization of reordering. It identifies the key parameters in a burst and packet reordering scenario and point out TCP critical scenarios.
