  • Network device data plane sandboxes for third-party controlled packet forwarding paths
    Patent number: 9967210
    Abstract: In some examples, a network device comprises a first application and a second application; a forwarding unit comprising an interface card to receive a packet; a packet processor; an internal forwarding path of the forwarding unit; a forwarding unit processor; a first interface; and a second interface. The first application is configured to configure, via the first interface, the internal forwarding path to include a sandbox that comprises a container for instructions to be configured inline within the internal forwarding path. The second application is configured to configure, via the second interface, the sandbox with second instructions that determine processing of packets within the sandbox. The packet processor is configured to process, in response to determining a packet received by the forwarding unit is associated with a packet flow controlled at least in part by the second application, the packet by executing the second instructions configured for the sandbox.
