1.6. Interconnection between devices

1.6.1. Viewing communication flows

Below, diagrams are displayed representing the various inputs/outputs of the GCap and the GCenter and the corresponding communication flows.

For the GCap or for the GCenter, there are two possible configurations for communicating:

• The double interface configuration is the mandatory mode in the event of a sensitive environment

  In this configuration:

  • One network port is used for secure communication between the probe and the GCenter via IPSEC tunnel

  • Another network port is used for the remote administration via the SSH protocol

• The single interface configuration, only one network port is used:

  • For secure communication between the probe and the GCenter via IPSEC tunnel

  • For the remote administration via the SSH protocol

The four cases of configuration are shown below:

---

1.6.1.1. Configuration: the GCap in single interface configuration and the GCenter in single interface configuration

---

1.6.1.2. Configuration: the GCap in single interface configuration and the GCenter in double interface configuration

---

1.6.1.3. Configuration: the GCap in double interface configuration and the GCenter in double interface configuration

---

1.6.1.4. Configuration: the GCap in double interface configuration and the GCenter in single interface configuration
