The following figure provides a high-level overview of the hardware components of the Open Telecommunications Platform.
10/100 Mbit Ethernet minimum is required by the management network. 10/100/1000 Mbit Ethernet is required by the provisioning and the data networks.
The above diagram represents one of the possible clustered OTP system configurations. In a standalone OTP host configuration, only the first OTP host is present.
The following list describes each of the Open Telecommunications Platform components.
External OTP installation server
A server that is used for a first-time installation of the Open Telecommunications Platform software to an OTP host using the OTP graphical user interface.
If you choose to install the Open Telecommunications Platform software manually using the command line, then the external OTP installation server is not required.
First OTP host
The first host in a clustered OTP system on which the Open Telecommunications Platform is installed. A standalone OTP host is comprised only of the first OTP host.
In a clustered OTP system, the first OTP host DHCP service allocates IP addresses to the OTP hosts for use by the provisioning network. The OTP system management service uses the provisioning network to load operating systems and updates to the additional OTP hosts.
The Solaris OS DHCP service is the only DHCP service supported by Open Telecommunications Platform 1.0. ISC DHCP is not supported.
Additional OTP hosts
One or more secondary hosts within a clustered OTP system that provide high availability. Additional OTP hosts are managed and monitored using the OTP high availability framework and the OTP system management service. Network Equipment Provider (NEP) applications can be provisioned to the OTP hosts using the OTP application provisioning service.
