The simplified block diagram below shows the basic software architecture of the DC-LMP protocol product.
For an overview of the DC-LMP software and its features, see DC-LMP Product Overview.
DC-LMP Software Components
The DC-LMP product consists of the following software components.
- Configuration Management: Implements the LMP and product MIBs.
- Control Channel Management: Bootstraps the IP control channel and ensures it remains operational.
- Link Property Correlation: Detects inconsistencies between local and remote link mappings.
- Link Verification: Automatically detects the link mappings between neighbors.
- Fault Localization: Isolates faults on an end to end light path to a single link.
- UNI Service Discovery: Implements the service discovery function for the UNI.
- Protocol Handling: Builds and decodes LMP protocol messages.
DC-LMP Interfaces
MIB Configuration and Management Interface
All aspects of DC-LMP configuration and management are accessible through the MIB interface. It uses Data Connection's N-BASE MIB management framework, which enables easy integration with SNMP, CORBA, TL1, GUI, or any other management solution.
Data Link Management Interface (DLMI)
This is the interface to the optical data links. It is used to
- send Test messages
- notify DC-LMP of Test messages received
- notify DC-LMP of data link failure
- explicitly test a data link during fault detection
- determine the connections between upstream and downstream links during fault detection
- notify DC-LMP of the allocation and deallocation of a particular data link.
IP Sockets Interface
Most of the LMP protocol messages flow as raw IP datagrams over the IP control channel. The IP Sockets interface is used to send and receive these messages through the underlying IP stack.
