Virtual Hardware Layer

The overall role of the Virtual Hardware Layer (VHL) sub-system is to provide a virtual layer between the Network Element hardware and the rest of the ECSP.

In general terms this includes the following responsibilities:

  • model Network Element hardware;
  • notify the ECSP of hardware alarms and events;
  • synchronise hardware with the ECSP;
  • support both low-level and high-level operations;
  • maintain current alarm status;
  • co-ordinate complex requests, such as cross-connects, protection, etc.

All external interfaces use the Proxy-Task (ie. thin-client) pattern, which provides a transparent link between components regardless of the platform or location.
