Network system, network management server, and configuration scheduling method, using summed processing time

A network system which has a plurality of transmission apparatuses for transmitting a packet and a management server and forms a logical network including the transmission apparatus,

• wherein the management server includes:
• a relation information storage unit configured to store a relationship between a first identifier of a logical network and second identifiers of a plurality of the transmission apparatuses forming the logical network;
• a configuration reservation information storage unit configured to store a reservation information for each time zone and each transmission apparatus, the reservation information indicating whether the transmission apparatus is already reserved in the time zone or not reserved in the time zone;
• a processing time storage unit which stores processing time relating to a third identifier of a configuration data information which is an item set to the transmission apparatus;
• and
• a processing unit,
• wherein the processing unit is configured to:
• receive a first configuration request of a logical network from a user management terminal, the first configuration request including the first identifier and the third identifier, and
• execute reservation processing including:
• obtaining the second identifiers from the relation information storage unit by referring to the relation information storage unit based on the first identifier;
• obtaining, as an obtained processing time, a cumulative processing time needed for the first configuration request, by referring to the processing time storage unit based on the third identifier;
• identifying a first time zone which satisfies the obtained processing time of every transmission apparatus corresponding to the second identifiers, by referring to the configuration reservation information storage unit;
• making a reservation for the first time zone in the configuration reservation information storage unit;
• and
• transmitting a scheduled period notice including the first time zone to the user management terminal.

A configuration scheduling method for scheduling a setting of a logical network in a network system, which has both a plurality of transmission apparatuses for transmitting a packet and a management server, the method comprising:

• storing, in a relation information storage unit, a relationship between a first identifier of the logical network and second identifiers of a plurality of the transmission apparatuses forming the logical network;
• storing, in a configuration reservation information storage unit, a reservation information for each time zone and each transmission apparatus, the reservation information indicating whether the transmission apparatus is already reserved in the time zone or not reserved in the time zone;
• storing, in a processing time storage unit, processing time relating to a third identifier of a configuration data information which is an item set to the transmission apparatus;
• and
• executing, via a processing unit, operations including:
• receiving a first configuration request of a logical network from a user management terminal, the first configuration request including the first identifier and the third identifier, and
• executing reservation processing including operations of:
• obtaining the second identifiers from the relation information storage unit by referring to the relation information storage unit based on the first identifier;
• obtaining, as an obtained processing time, a cumulative processing time needed for the first configuration request, by referring to the processing time storage unit based on the third identifier;
• identifying a first time zone which satisfies the obtained processing time of every transmission apparatus corresponding to the second identifiers, by referring to the configuration reservation information storage unit;
• making a reservation for the first time zone in the configuration reservation information storage unit;
• and
• transmitting a scheduled period notice including the first time zone to the user management terminal.
