Introduction to Bonjour Policies and New Requirements
As mentioned in the figure above, improvements to Bonjour services are made, and Bonjour policies are
introduced to allow per service instance (MAC address) configuration that mandates how the service
instance is shared, which is articulated as follows:
introduced to allow per service instance (MAC address) configuration that mandates how the service
instance is shared, which is articulated as follows:
•
Service instance is shared with whom (user-id).
•
Service instance is shared with which role/s (client-role).
•
What is the location allowed to access the service instance (client location).
This configuration can be applied to wired and wireless service instances, and the response to any query
will solely be based on the policy configured for each service instance. This allows selective sharing of
service instances based on the location, user-id, or role. Since most service publishing devices are wired,
this allows filtering of wired services at par with wireless service instances. While mDNS profile
associated with the client checks for service type being queried before responding to the query, the
access policy further allows filtering of specific service instances based on querying client location, role,
or user-id.

With Bonjour access policy, there are two levels of filtering the client queries, which are as follows:
•
At the service type level by using the mDNS profile.
•
At the service instance level using the access policy associated with the service each instance.
