Low traffic network management method using estimated process execution time for manager-agent synchronization
First Claim
1. A management method for a communication network wherein a management station is connected to at least one agent station, comprising the steps of:
- a) transmitting an execution request message from the management station to said agent station for requesting the agent station to execute a process;
b) responsive to the execution request message, estimating, at said agent station, a length of time taken to execute the process and transmitting a first reply message to the management station, indicating said length of time, and subsequently estimating a length of time remaining to execute said process;
c) setting a timer, at said management station, according to the length of time contained in the first reply message, starting the timer, and transmitting a time request message to the agent station when said timer expires;
d) responsive to the time request message, transmitting, from the agent station to the management station, a second reply message indicating the estimated length of remaining time; and
e) responsive to the second reply message, determining, at said management station, that the requested process has been executed if the second reply message indicates that the length of remaining time is zero, or setting the timer according to the second reply message if the length of remaining time is nonzero, starting the timer, and determining that the requested process has been executed when the timer expires.

Abstract
In a communication network wherein a management station is connected to at least one agent station, an execution request message is first transmitted from the management station to the agent station for requesting it to execute a process. In response, the agent station estimates a length of time taken to execute the process and transmits a first reply message to the management station, and subsequently estimates a length of time remaining to complete the execution of the process. The management station sets a timer according to the length of time contained in the first reply message and starts the timer. When the timer expires, the management station transmits a time request message to the agent station. In response, the agent station transmits a second reply message containing the remaining time. In response to the second reply message, the management station determines that the requested process has been executed if the remaining time is zero. If the remaining time is nonzero, the management station sets the timer according to the second reply message, starts it and determines that the requested process has been executed when the timer expires.

3. A communication network comprising;
-
a management station having a timer; and at least one agent station connected to the management station, said management station transmitting an execution request message to said agent station for requesting the agent station to execute a process, setting and starting said timer according to time data, and transmitting a time request message to the agent station when said timer expires, the agent station being responsive to said execution request message for estimating a length of time taken to execute said process, transmitting a first reply message containing the estimated length of time as said time data to said management station, subsequently estimating a length of time remaining to execute said process, the agent station being further responsive to the time request message subsequently received from the management station for transmitting a second reply message indicating the remaining time, said management station determining that the requested process has been executed if the remaining time contained in the second reply message is zero, or setting said timer according to the second reply message if the remaining time is nonzero, starting said timer, and determining that the requested process has been executed when the timer expires. - View Dependent Claims (4, 5)
