Abstract

An apparatus for helping with multicast domain name service (MDNS) discovery includes one or more processors configured to receive a first MDNS query from the resource-seeking device, receive a first MDNS response from the resource-providing device, and generate a second MDNS response according to the first MDNS response. The second MDNS response is generated at least by including a resource record from the first MDNS response and setting a time-to-live (TTL) value of the resource record in the second MDNS response to be lower than an original TTL value as specified for the resource record in the first MDNS response. The second MDNS response is sent to the resource-seeking device in response to the first MDNS query. A hospitality establishment may thereby soft assign a media device to a user device while retaining the ability to change the media device assigned to the user device.

Claims20

Dependent claims

An apparatus for helping with multicast domain name service (MDNS) discovery between resourcing-seeking and resource-providing devices on different computer networks, the apparatus comprising:

one or more network interfaces connectable to a first network and a second network;
one or more storage devices storing a plurality of software instructions;
and
one or more processors coupled to the one or more network interfaces and the one or more storage devices;
wherein, by the one or more processors executing the software instructions loaded from the one or more storage devices, the one or more processors are configured to:
receive an incoming MDNS query from a resource-seeking device via the first network;
select an available resource-providing device from a plurality of resource-providing devices on the second network;
send an outgoing MDNS query to the available resource-providing device via the second network;
receive an original MDNS response from the available resource-providing device via the second network;
modify one or more resource records of the incoming MDNS response to form a modified MDNS response, the modified MDNS response at least including a resource record from the original MDNS response but having a time-to-live (TTL) value of the resource record in the modified MDNS response modified to be a lower value than an original time-to-live (TTL) value as specified for the resource record in the original MDNS response from the available media device;
and
send the modified MDNS response to the resource-seeking device via the first network.
