摘要： 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.
