Abstract
Disclosed are a flow table ageing method, device and system and a computer-readable medium. The method can comprise: a switch receives a flow table configuration message issued by a controller; the switch sets a data volume life cycle parameter value of a flow table according to the flow table configuration message; and when a data volume matched according to the flow table of the switch reaches the data volume life cycle parameter value of the flow table, the switch ages the flow table.
Claims21
A method for ageing a flow table comprising:
- receiving, by a switch, a configuration message for the flow table issued by a controller, wherein the configuration message for the flow table comprises a parameter value of a life cycle for a data volume of the flow table;
- setting, by the switch, the parameter value of the life cycle for the data volume of the flow table according to the configuration message for the flow table;
- and
- ageing the flow table by the switch, when a data volume, for which matching is performed by the switch according to the flow table, reaches the parameter value of the life cycle for the data volume of the flow table.
A method for ageing a flow table comprising:
- encapsulating, by a controller, a parameter value of a life cycle for a data volume of the flow table into a configuration message for the flow table;
- and
- issuing, by the controller, the configuration message for the flow table to a switch, wherein the configuration message for the flow table is arranged for the switch to set the flow table.
A switch comprising:
- a receiving unit, a flow table setting unit and a flow table ageing unit, wherein
- the receiving unit is configured to receive a configuration message for a flow table issued by a controller, wherein the configuration message for the flow table comprises a parameter value of a life cycle for a data volume of the flow table;
- the flow table setting unit is configured to set the parameter value of the life cycle for the data volume of the flow table according to the configuration message for the flow table received by the receiving unit;
- and
- the flow table ageing unit is configured to age the flow table, when a data volume, for which matching is performed by the switch according to the flow table, reaches the parameter value of the life cycle for the data volume of the flow table.
A controller comprising an encapsulating unit and a sending unit, wherein
- the encapsulating unit is configured to encapsulate a parameter value of a life cycle for a data volume of a flow table into a configuration message for the flow table;
- and
- the sending unit is configured to issue the configuration message for the flow table encapsulated by the encapsulating unit to a switch, wherein the configuration message for the flow table is arranged for the switch to set the flow table.
