Problems solved by technology

[0005] Bonjour discovers and advertises services through local multicast, so while it is easy to discover, it also limits these services to the second-tier network and cannot cross the third-tier network, so that service information cannot be found in the entire network. The whole network application brings inconvenience

Embodiment 1

[0034] see figure 1 , figure 1 It is a schematic flowchart of a method for implementing zero-configuration networking protocol services in Embodiment 1 of the present invention. The specific steps are:

[0035] Step 101, when the Bonjour monitoring device in any subnet monitors the Bonjour service announcement or response message in the subnet, update the DNS resource entry record of the Bonjour service carried in the announcement or response message to the local database , and at the same time, synchronize the DNS resource entry to the Bonjour management device in the networking.

[0036] The content of the DNS resource entry recorded by the Bonjour monitoring device is the same as the existing implementation, including but not limited to the service instance number, IP address and service type. The IP address is the IP address of the device responding or announcing the Bonjour service.

[0037] In this step, when the Bonjour monitoring device records and updates the DNS ...

Embodiment 2

[0060] see figure 2 , figure 2 It is a schematic flowchart of a method for implementing zero-configuration networking protocol services in Embodiment 2 of the present invention. The specific steps are:

[0061] Step 201 , when the Bonjour management device in the networking receives the Bonjour service synchronized by the Bonjour listening device in each subnet, it records and updates the DNS resource entries of each Bonjour service.

[0062] The Bonjour management device receives the Bonjour service synchronized by the Bonjour monitoring device in each subnet, if it is a newly added Bonjour service, record the DNS resource entry of the Bonjour service; if it is the Bonjour service deleted by the Bonjour monitoring device, Delete the DNS resource entry corresponding to the Bonjour service.

[0063] Step 202, the Bonjour management device sends the Bonjour service corresponding to the recorded DNS resource entry to the Bonjour monitoring devices in each subnet, so that eac...

Abstract

The present application discloses a method for realizing zero-configuration networking protocol (Bonjour) service, the method comprising: a network device as a Bonjour monitoring device in the subnet, monitoring local Bonjour services, summing them up to a Bonjour management device, and receiving Bonjour The management device notifies and records the Bonjour services in other subnets, and responds to the terminal with the corresponding Bonjour services in other subnets when receiving the mDNS message sent by the terminal in this subnet to query a certain Bonjour service. Based on the same inventive idea, this application also proposes a network device that enables terminals in any subnet to discover Bonjour services across the entire network, and can centrally manage Bonjour services across a three-layer network through one device.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and network equipment for implementing zero-configuration networking protocol services. Background technique [0002] The zero-configuration networking protocol (Bonjour) is the name given to the open zero-configuration networking standard based on the multicast domain name service (multicast Domain Name System, mDNS). Devices using Bonjour automatically broadcast their own service information in the network and listen to the service information of other devices, as if greeting each other. [0003] In this way, Bonjour makes it easy to find systems and services on the LAN even without a network administrator. Bonjour displays the names of devices and applications that support multicast Domain Name Protocol in the LAN, and uses mDNS to resolve device naming conflicts in the LAN. [0004] Many devices, servers, and other network services, such as pri...
