METHOD FOR MANAGING AND SHARING SYMMETRIC FLOW AND ASYMMETRIC FLOW IN DUPLEXED NETWORK

摘要

A network dualizing device according to the present invention comprises multiple network interface units which store information on a flow flowing in the network interface units when no information on the flow exists and which provide the information on the flow for a master unit when the flow accords with an asymmetric flow; and the master unit which stores the information on the flow provided by the network interface units and which provides information on an opposite flow for the network interface units when the information on the opposite flow is stored in the master unit. Therefore, the present invention enables integrated management and analysis for the asymmetric flow which has different paths for taking in and discharging packets.
