USP Structure
The Consumer Companies Platform consists of a group of Endpoints (Brokers and Controllers) that enables functions to govern “Service Components.” These Service Components are made up of a set of Objects and Parameters outlined within the Agent’s supported knowledge mannequin and uncovered because the Agent’s instantiated knowledge mannequin. These Service Components mannequin a given service, comparable to community interfaces, software program modules, machine firmware, distant parts proxied by way of one other interface, digital parts, or different managed providers.
A Controller could also be an Autoconfiguration Server (ACS) much like TR-069, managed by an software service supplier to manage particular parts, or perhaps a Controller on a smartphone or within the gateway to govern parts within the person’s community.
USP is made up of a number of architectural elements:
- Mechanism for discovery and belief institution.
- A way for encoding messages for transport.
- A system for end-to-end confidentiality, integrity, and identification authentication.
- Transport of messages over a number of Message Switch Protocols (MTP) with related MTP safety.
- A set of standardized messages primarily based on the CRUD mannequin (create, learn, replace, delete), plus an object-defined operations mechanism and a notification mechanism (CRUD-ON).
- Authorization and entry management on a per-element foundation.
- A way for modeling service parts utilizing a set of objects, parameters, operations, and occasions (supported and instantiated knowledge fashions).
- Multi-tenancy assist.
USP Protocol Stack
All USP messages comparable to Add/Set/Get/Delete are encoded utilizing Protobuf and encapsulated in a USP file. These data are used to ensure the integrity of the USP messages and supply a layer of safety when safety can’t be achieved on the message transport layer. USP Information permit an optionally available Session Context that enables for protected messages (payloads) and the segmentation and re-assembly of USP messages when giant messages must traverse intermediate proxies.
Knowledge Mannequin
USP is designed to permit a Controller to govern Service Components on an Agent utilizing a standardized description of these Service Components. This standardized description is named an data mannequin, and an data mannequin that’s additional specified to be used in a specific protocol is named a “Knowledge Mannequin.” This Knowledge Mannequin is laid out in XML.
The information mannequin for describing the service parts uncovered by USP Brokers is outlined within the Machine:2 Root Knowledge Mannequin (revealed as TR-181 Difficulty 2). The fashions for CWMP and USP pull from the identical widespread core with some minor modifications for protocol-specific administration objects.
USP In Motion with MQTT MTP
USP Messages are exchanged between Controllers and Brokers. In some deployment situations, the Controller and Agent have a direct connection. In different deployment situations, the messages exchanged by the Controller and Agent traverse a number of intermediate MTP Proxies. The latter deployment state of affairs usually happens when the Agent or Controller is deployed outdoors the proximal or Native Space Community.
USP messages are despatched between Endpoints over a number of Message Switch Protocols.
The Message Queuing Telemetry Transport (MQTT) MTP transfers USP Information between USP Endpoints utilizing the MQTT protocol. Messages which are transferred between MQTT purchasers make the most of a message bus interplay mannequin the place the MQTT server is the messaging dealer that routes and delivers messages primarily based on the Subject Identify included within the MQTT Publish packet variable header.
