摘　　要：　为了在光突发交换网络中提供端到端的区分服务,提出了一种区分服务模型,并详细介绍了其功能。提出了一种控制分组的区分服务编码点,详细研究了一系列区分服务规则,包括编码点的改写和更新以及区分服务模型的可扩展性。同时提出了几个有待进一步研究的问题。A differentiated service (DiffServ) model is proposed to support end-to-end differentiated services, and several function terms are explained in detail. In order to implement DiffServ in optical burst switched (OBS) networks, a kind of DiffServ code-point in control packet is presented. A series of DiffServ rules are studied in detail, including the overwriting and updating of DiffServ code-point and the scalability of DiffServ model. Also several issues which need to be improved are revealed.
