Connecting a corporate Presence Domain with a service such as AOL is known as what?

Connecting a corporate Presence Domain with an external service like AOL is referred to as intra-domain federation. In this context, "intra-domain" implies that the connection is made within a specific domain or network environment, enabling communication and presence information sharing between the corporate domain and the external service while still maintaining domain boundaries.

This type of federation allows users from the corporate domain to interact with users on external services, facilitating a seamless exchange of presence information in a controlled manner. It is crucial for organizations that want to maintain some level of collaboration outside their own network while ensuring security and privacy protocols are respected.

Other terms, such as inter-domain federation, typically refer to connections between distinct networks or systems, and global federation refers to a broader concept of multiple domains working together across different geographic or logical boundaries. A cross-domain alliance would imply a collaborative arrangement but lacks the specific clarity that "intra-domain federation" provides in representing the relationship between a corporate domain and a specific external service.
