Abstract: Disclosed is a method to enable printing on legacy devices. The method includes discovering a legacy device that does not have a universal record that enables the legacy device to provide services to a mobile device through a network, appending the universal record for the legacy device, transmitting the universal record for the legacy device to a controller, receiving, at the controller and from the mobile device, a request for services which can be provided by the legacy device, transmitting, from the controller and based on the universal record for the legacy device, data associated with the legacy device to the mobile device to yield transmitted data and transmitting, based on an acceptance of the transmitted data by the mobile device, a service request from the mobile device to the legacy device for providing a service to the mobile device.

Abstract: Systems, methods, and computer-readable media for implementing zero-configuration networking over a wide area network. Disclosed are systems, methods, and computer-readable storage media for implementing zero-configuration networking over a wire area network by utilizing agents, application programming interfaces (API), and a controller. The controller can implement polices for communication between the agents and APIs, enabling zero-configuration network

Abstract: This technology enables a dynamic host configuration protocol (“DHCP”) Layer 2 relay in a Virtual Extensible Local Area Network (“VXLAN”) overlay fabric. A host device broadcasts a configuration request, such as a DHCP discover, across an Ethernet virtual private network (“EVPN”) overlay fabric. The DHCP discover is intercepted by a VXLAN Tunnel End Point (“VTEP”) device with Layer 2 bridging functionality. The VTEP device selects a centralized gateway (“CGW”) device with Layer 3 relay functionality as a destination for the DHCP discover. The VTEP device encapsulates the DHCP discover with a unicast VXLAN header comprising the media access control (“MAC”) address of the CGW device and transmits the encapsulated DHCP discover to the CGW device, resolving the destination address associated with the broadcast. The CGW device transmits the DHCP discover to an Internet Protocol (“IP”) address associated with a DHCP server that is external to the EVPN overlay fabric.

Abstract: Systems, methods, and computer-readable media for implementing local and wide network suppression of query requests in zero-configuration networking. Disclosed are systems, methods, and computer-readable storage media for implementing suppression of query packets zero-configuration networking over local and wide networks by utilizing agents, application programming interfaces (API), and a controller. The suppression can be determined based on two time periods, a processing period and a suppression period.
