The DXL architecture allows DXL clients (services) to communicate with each over the message bus in near real time. Apps simply publish and subscribe to message topics, or make calls to DXL services in a request/response invocation similar to RESTful APIs. The fabric delivers the messages and calls immediately.
Brokers are responsible for routing messages between clients connected to the message bus. Brokers can be connected to each other (“bridged”) to allow for redundancy, scalability, and communication across different geographical locations.
Clients connect to brokers for the purposes of exchanging messages. Communication with brokers is over a TLS-based connection with bi-directional authentication (PKI).
McAfee ePO is used to manage McAfee products, including DXL. McAfee ePO maintains the DXL fabric topology information and authorization rules for the fabric, and provides views for visualizing the fabric’s current state.
