Abstract
In a management system comprising a manager connected to a number of agents a trap table is provided in the agent. Each trap transmitted from the agent to the manager is given an incremented number so that if the manager does not receive a trap, the manager knows which trap to request from the agent using an SNMP get-request message. The information of the trap message can then be fetched from the trap table in the agent and transmitted in a response message to the manager. A trap counter is also provided in the agent. The trap counter is set equal to the number of the last sent trap in connection with the sending of the trap.
Claims9
A method of providing synchronization, in an SNMP based management network for power supply units in a telecommunication system, between an agent and a manager, where the agent has a MIB comprising a definition of a trap table for storing information regarding information transmitted from the agent to the manager as trap messages using a User Datagram Protocol (UDP), characterized by the steps of:
- assigning to each trap message sent from the agent a trap number and storing said number;
- controlling in the manager the receipt of consecutive traps;
- transmitting a get-request message from the manager to the agent requesting trap message information associated with a particular trap number or several trap numbers missing or not complete;
- in the agent, fetching from the trap table the trap message information associated with the assigned trap number(s), and
- as a response to the get-request message, transmitting a get-response message from the agent to the manager comprising the trap message information fetched from the trap table of the agent
A method according to any of the proceeding claims characterized in that the manager on the loss of information due to up-start etc. retrieves from the agent the trap number of the last trap message fetched from the agent's trap counter.
A computer program, which when run on a computer, performs the following steps in a synchronization method, in an SNMP based management network for power supply units in a telecommunication system, between an agent and a manager, where the agent has a MIB defining a trap table for storing information regarding information transmitted from the agent to the manager as trap messages using a User Datagram Protocol (UDP):
- assigning to each trap message sent from the agent a trap number and storing said number;
- controlling in the manager the receipt of consecutive traps;
- transmitting a get-request message from the manager to the agent requesting trap message information associated with a particular trap number or several trap numbers missing or not complete;
- in the agent, fetching from the trap table in the agent the trap message information associated with the assigned trap number(s), and
- as a response to the get-request message, transmitting a get-response message from the agent to the manager comprising the trap message information fetched from the trap table of the agent.
A system providing synchronization, in an SNMP based management network for power supply units in a telecommunication system, between an agent and a manager, where the agent has a MIB defining a trap table for storing information regarding information transmitted from the agent to the manager as trap messages using a User Datagram Protocol (UDP);
- means for transmitting a get-request message from the manager to the agent requesting the information associated with a particular trap number or several trap numbers;
- in the agent, means for fetching from the trap table in the agent the trap message information associated with the trap number(s), and
- means for transmitting a get-response message from the agent to the manager comprising the trap message information fetched from the trap table as a response to the get-request message.
