The performance of accessing network memory via high-speed network has much advantage compared with that via local disk. So, to expand local physical memory by using the network memory has gained broad attention. This paper presents a SDNMS (scalable dynamic network memory service) system. SDNMS provides standard service interface therefore can be applied to any client system which needs to expand their local memory. SDNMS is transparent, thus client applications can run normally without any modify. Dynamic sharing, scalability features are also provided by SDNMS. This paper also implemented a MLM (memory load manager) module in client system of SDNMS. Through MLM, total amount of local memory allocated to an application can be constrained. Thus local memory needed by other applications can be assured. It also supports bounding network memory on demand, thus memory provided by SDNMS can be fully utilized. We conducted experiments on Mysql, Spec2000 and Office applications which have many interactions with disk. The experiments testified that network memory service is practical. It also showed that performance is improved obviously after adopting SDNMS system
