Abstract:
GSOC Open Management Subsystem (GOMS)
Integrated open Management of Control Centre Network and Tasks

The surveillance of both the network (including the computers) and 
the tasks of a control centre id of paramount importance. Open 
Network Management Systems based on standard protocols (CMIP or SNMP) 
have proficiently improved the supervision of networks. The 
utilisation of commercial of the shelf network management products 
improves the quality of network monitoring & control and cuts down 
the operational effort.

These standard management systems allow no real management of the 
tasks running on the control centre computers. The German Spacecraft 
Operating Centre (GSOC) sees the need for the management of 
operational applicationes. As there is no standard available the 
following goals were defined:

-  Management of all suitable operational applications using SNMP

-  Modelling of the management aspects of the applications by 
   extensions to the standard MIB-II.

-  Performance of the management by using a COTS Network Management 
   Framework.

-  Provision of an API to interface applications to the management 
   system.

For the realisation of the management subsystem POLYCENTER NetView 
running under Digital-UNIX was chosen as management system. The 
following components were developed in the scope of the project:

-  A map configuration tool as utility-program running directly under 
   the PolyCenter Netview program  for the automatic generation of 
   mission / projects submaps.

-  The GOMS application manager running directly under the PolyCenter 
   Netview program for the integrated management of operational tasks.

-  The GOMS-MIB. As there is no MIB available which seems adequate to 
   the operational constraints, a MIB for telemetry applications was 
   defined.

-  The GOMS SNMP agent/proxy to be able to manage tasks shich run on 
   computers without TCP / IP communication.

-  The GOMS SNMP Application Server (SAS) task that interfaces both 
   to the SNMP agent and the application tasks.

-  The GOMS Managed Application Programming Interface (MAAPI) to 
   allow the interfacing of the tasks.

The GOMS (GSOC Open Management Subsystem) offers full integrated 
network and task management using a standard management protocol. The 
complete system will allow the integrated management of all 
operational GSOC network, computers and tasks from one operator 
position. Thus  the GSOC will be able of reducing mission costs and 
simultaneously introducing a significantly higher level of 
operational control
