perhaps to the external network at large. Consequently, it is assumed that all communication

between DX Content Router services occurs over a secure TCP connection.

The following diagram illustrates, at a high level, the flow of messages that takes place between

two DX Storage clusters, one acting as the Primary Cluster and the other as a Disaster Recovery

Cluster. Dotted lines represent local cluster communication. Solid lines represent TCP traffic over

the HTTP protocol between DX Content Router services and also between storage nodes within the

two independent clusters.

Alternatively, if network configuration prevents direct communication between the storage nodes

(such as when DX Content Router installed on a CSN), communications can be configured to route

through an SCSP Proxy:
