Abstract: Provided are an in-memory management system and method using user traffic. According to embodiments thereof, traffic bandwidth is monitored for an ERP user who has left an LAN coverage area, by using an OpenFlow-based SDN WAN, and loading or unloading of a table partition set, an SQL Plan cache, and an SQL view cache in an in-memory is managed depending on a result of monitoring, so that the in-memory can be efficiently managed. The user traffic for the ERP user and the user can be monitored through the local network, and loading or unloading of table partitions of the in-memory can be managed on the basis of the monitored user traffic so that the in-memory can be managed regardless of Internet access. Data transmission rate and security can be enhanced because distributed communication is performed over an LAN and a WAN for each user and each ERP user.
