The merge and separate plus SAR method with QoS support in the high speed network node

Processing toward variable-length IP packets brings burden to high speed network node control, caching, management, etc. A popular solution uses a method similar to ATM segmentation and reassembly (SAR) in the non-ATM network node. In this paper, it is pointed out that the low-bandwidth usage of this method is not suitable for high speed network node realization. To reduce the redundant data rate (RDR) and improve packet switching rate, a new fixed-size processing method, merge and separate plus SAR (MAS+), in high speed network node is presented. In this new method, the packets larger than the fixed size are segmented. And, the computer simulations of RDR improvement and latency analysis of the new solution are also given in this paper.
