Abstract:

The invention that addresses the problem of authentication of the transport packet stream (which constitutes a flow within a session), which has been admitted into a managed packet network. Authentication and the subsequent policing of the flows supporting an identified client's authorized service prevent a large class of denial of service attacks described below. Specifically, the invention addresses two different matters: 1) key distribution and management 2) various forms of using a shared key for the authentication of transport packets on the user-to-network-interface (UNI).

Abstract:

Method and systems for controlling a hybrid network having software-defined network (SDN) switches and legacy switches include initializing a hybrid network topology by retrieving information on a physical and virtual infrastructure of the hybrid network; generating a path between two nodes on the hybrid network based on the physical and virtual infrastructure of the hybrid network; generating a virtual local area network by issuing remote procedure call instructions to legacy switches in accordance with a network configuration request; and generating an SDN network slice by issuing SDN commands to SDN switches in accordance with the network configuration request.
