The paper proposes two IP packet aggregation techniques, called DAT (Deterministic Aggregation Technique) and WATT (Work-conserving Aggregation Technique with Timer), to adapt IP traffic to a multi-service optical slotted network. To perform aggregation, IP packets belonging to different classes of service (CoS) are polled according to the strict priority (SP) or to an hybrid version of the probabilistic priority (PP) scheduling discipline originally proposed in [1, 2]. An approximate analytical model is given in the case of DAT under the SP discipline. In addition, extensive simulations are used to study the impact of self-similar traffic on the aggregation processes. Finally, performance comparisons between the aggregation techniques and the standard approach (where no aggregation is performed) are carried out in the context of a slotted dual bus optical ring network (SDBORN) which is a candidate viable solution for metropolitan area networks (MAN).
