US 10,833,948 B2 · Zero configuration networking on a subnetted network

Abstract

Methods and apparatus are described for implementing service discovery protocols on subnetted zero configuration networks. A process for managing service advertisement across a plurality of subnets may comprise: collecting service advertisements on a local network level by designated network devices; sending listings of services from each of the designated devices to a master network device; sending a table of services for the plurality of subnets from the master device to all of the designated devices on the plurality of subnets; creating by each of the designated network devices for the corresponding subnet a service discovery proxy table listing the service advertisements on the subnets of the plurality of subnets beyond the subnet corresponding to the designated device; and periodically transmitting by each of the designated devices on the corresponding subnets service advertisements for the services of the corresponding service discovery proxy table.

Dependent claims

A method, comprising:

collecting, by a designated network device of a plurality of designated network devices, service advertisements on a local network from a subnet of a plurality of subnets to which the designated network device belongs;
selecting, by the designated network device, one or more service advertisements based on a plurality of filtering rules corresponding to the plurality of subnets to send the selected one or more service advertisements to a network device designated as a master network device for the plurality of designated network devices of the plurality of subnets;
receiving, by the designated network device, a table of services that includes service advertisements received by the master network device from the plurality of designated network devices of the plurality of subnets;
creating, by the designated network device, a service discovery proxy table based on the table of services to allow one or more service advertisements listed in the table of services to be available in the subnet;
and
transmitting, by the designated network device, one or more service advertisements for the services listed in the service discovery proxy table.

3 more elements

A system, comprising:

one or more processors;
and
a memory storing instructions that, when executed by the one or more processors, cause the system to perform operations comprising:
collecting, by a designated network device of a plurality of designated network devices, service advertisements on a local network from a subnet of a plurality of subnets to which the designated network device belongs;
selecting, by the designated network device, one or more service advertisements based on a plurality of filtering rules corresponding to the plurality of subnets to send the selected one or more service advertisements to a network device designated as a master network device for the plurality of designated network devices of the plurality of subnets;
receiving, by the designated network device, a table of services that includes service advertisements received by the master network device from the plurality of designated network devices of the plurality of subnets;
creating, by the designated network device, a service discovery proxy table based on the table of services to allow one or more service advertisements listed in the table of services to be available in the subnet;
and
transmitting, by the designated network device, one or more service advertisements for the services listed in the service discovery proxy table.

6 more elements

A non-transitory, tangible computer-readable media having instructions stored thereon that, when executed by at least one processor, causes the at least one processor to perform operations comprising:

collecting, by a designated network device of a plurality of designated network devices, service advertisements on a local network from a subnet of a plurality of subnets to which the designated network device belongs;
selecting, by the designated network device, one or more service advertisements based on a plurality of filtering rules corresponding to the plurality of subnets to send the selected one or more service advertisements to a network device designated as a master network device for the plurality of designated network devices of the plurality of subnets;
receiving, by the designated network device, a table of services that includes one or more service advertisements received by the master network device from the plurality of designated network devices of the plurality of subnets;
creating, by the designated network device, a service discovery proxy table based on the table of services to allow one or more service advertisements listed in the table of services to be available in the subnet;
and
transmitting, by the designated network device, one or more service advertisements for the services listed in the service discovery proxy table.
