Abstract
System and method of dynamically switching among multiple WANs for data transmission to and from a LAN based on real-time network performance. Each WAN may be owned by a respective Internet Service Provider (ISP) of the LAN. A switching device coupled between the WAN and the LAN evaluates the real-time network performance of the current WAN used for data transmission between a LAN user device and a target IP address. If the network performance deteriorates, the switching device may select a different WAN for the data transmission according to a set of service quality policies. The switching device may maintain a flow table to control data routing and communicate with other components in the LAN in compliance with the OpenFlow protocol.
