Abstract
A network device has a Local Area Network (LAN) port and several Wide Area Network (WAN) ports. The network device detects a computing device that is connected to the LAN port initiating establishment of a TCP connection. The network device creates a TCP socket that establishes the TCP connection with the computing device and inspects TCP packets on the TCP connection to identify a cloud application associated with the TCP packets. The network device creates another TCP socket that establishes a TCP connection to the identified cloud application by way of a WAN port that is designated to be an output port for the identified cloud application. A routing path is created between the LAN port and the designated WAN port. Subsequent TCP packets originated by the computing device for the identified cloud application are forwarded along the routing path.
