USRM Plug-In Components
The USRM consists of a core platform plus a set of plug-in software components that
implement a specific application. The three types of plug-in components are:
implement a specific application. The three types of plug-in components are:
Resource Models
Resource Adaptors
Applications
Resource Models
A resource model is a data representation of a network resource used by the USRM.
Note that in the context of the USRM, the term resource also refers to a resource
model. The resource software component is a data model that maintains a container
for the data that represents the configuration and status of the network device. This
model contains:
Note that in the context of the USRM, the term resource also refers to a resource
model. The resource software component is a data model that maintains a container
for the data that represents the configuration and status of the network device. This
model contains:
The basic configuration (number of ports, number of sessions per port, etc.) of
the device
the device
The state and status (frequency, TSID, etc.) of the network device
Information used by the USRM to maintain video services on the device

For example, the USRM maintains a complete representation of all
sessions on QAMs to allow the QAM to be refreshed in the event of a
reset of the network resource.
sessions on QAMs to allow the QAM to be refreshed in the event of a
reset of the network resource.
The four types of resource models are as follows:
Encryptor
QAM
CA (Conditional Access)-Managers
Edge Resource Manager (ERM)
Note: As new resource models are implemented, the USRM will support those as
well. For example, later versions will also support a streamer resource to generate
switched unicast streams. Adding a new resource model type only requires adding
a folder for the new type in the USRM hierarchy. The hierarchy refers to how
components and devices are grouped for display on the tree control of the user Web
interface.
