METHOD AND APPARATUS FOR APPLICATION AND L4-L7 PROTOCOL AWARE DYNAMIC NETWORK ACCESS CONTROL, THREAT MANAGEMENT AND OPTIMIZATIONS IN SDN BASED NETWORKS

摘要

A multi-cloud fabric system includes an open flow switch responsive to a first and subsequent data packets and a services controller including a flow database. Further, the multi-cloud fabric system includes a SDN controller that communicates with the services controller through an open flow switch, wherein upon the receipt of the first data packet, the open flow switch directs the first packet to the services controller. The services controller creates a flow entry and makes authentication decisions based on authentication information. The open flow controller based on authentication policies, determines whether to allow or deny access to a corporate network based on saved authentication policies and if the open flow controller determines to deny access, the first packet being re-directed to an authentication server for access.
