Study of MPLS Stream Merging over ATM

JIANG Ning kang, WANG Shi bing, LI Yu lin (National Key Lab. of Fiber Optic Local Communication Networks, Shanghai Jiaotong Univ., Shanghai 200030, China)  
In Multiprotocol Label Switching (MPLS), VC merging enables multi IP flows to be mapped onto the same VC label if they have the same destination. It provides a scalable solution for the network growth. This paper studied several approaches having been proposed to this day and analyzed their main problems, such as the additional buffering, protocol overhead, delay etc., which make the provision of QoS difficult to achieve. With the help of re coding two bits inside the head of ATM cell, this paper put forward a new MPLS VC merge capable scheduler. It allows cells to be interleaved with one another and be uniquely identified. The new scheduler has several properties: ① simple to implement, ② requiring no extra buffer and protocol overhead, ③ maintaining per flow QoS. However, it may introduce a minimal waste of link bandwith when utilization is low due to the approximately GPS round robin scheduler it uses.
