Abstract

Methods of processing a packet, APs, ACs and non-transitory machine-readable storage mediums are provided in examples of the present disclosure. In one aspect, an AP receives an Internet-of-Things data packet sent by an Internet-of-Things sensor, wherein a sensor identifier of the Internet-of-Things sensor is carried in the Internet-of-Things data packet; and sends the received Internet-of-Things data packet to an AC such that the AC processes the Internet-of-Things data packet based on the sensor identifier.

First claim

The invention claimed is:

1. A method of processing a packet, comprising:
receiving, by an Access Point (AP), an Internet-of-Things data packet sent by an Internet-of-Things sensor, wherein a sensor identifier of the Internet-of-Things sensor is carried in the Internet-of-Things data packet;
performing, by the AP, Control And Provisioning of Wireless Access Points Protocol Specification CAPWAP tunnel encapsulation for the Internet-of-Things data packet to carry an Internet-of-Things port number in the tunnel encapsulation;
sending, by the AP, the encapsulated Internet-of-Things data packet to an Access Controller (AC) such that the AC determine that the received packet is an Internet-of-Things data packet based on the Internet-of-Things port number and processes the Internet-of-Things data packet based on the sensor identifier;
allocating, by the AP, a virtual sub-card identifier for the Internet-of-Things sensor; and
sending, by the AP, a first correspondence between the virtual sub-card identifier corresponding to the Internet-of-Things sensor and an interface identifier of an interface connected with the Internet-of-Things sensor on the AP to the AC such that the AC generates a topology of the AP and a virtual sub-card based on the first correspondence.

2. The method according to claim 1 , further comprising:
generating a second correspondence between the sensor identifier of the Internet-of-Things sensor and the virtual sub-card identifier corresponding to the Internet-of-Things sensor,
wherein sending the received Internet-of-Things data packet to the AC comprises:
determining, by the AP, a corresponding virtual sub-card identifier based on the second correspondence and the sensor identifier carried in the Internet-of-Things data packet; and
sending, by the AP, the determined virtual sub-card identifier and the Internet-of-Things data packet to the AC such that the AC performs management for the Internet-of-Things sensor based on the virtual sub-card identifier and the topology of the AP and the virtual sub-card.

3. The method according to claim 1 , further comprising:
setting, by the AP, a destination port number of the Internet-of-Things data packet as a preset Internet-of-Things port number.

4. An Access Point (AP), comprising:
a processor, and
a machine-readable storage medium storing machine executable instructions which are executable by the processor to:
receive an Internet-of-Things data packet sent by an Internet-of-Things sensor, wherein a sensor identifier of the Internet-of-Things sensor is carried in the Internet-of-Things data packet; perform Control And Provisioning of Wireless Access Points Protocol Specification CAPWAP tunnel encapsulation for the Internet-of-Things data packet to carry an Internet-of-Things port number in the tunnel encapsulation;
send the encapsulated Internet-of-Things data packet to an Access Controller (AC) such that the AC determine that the received packet is an Internet-of-Things data packet based on the Internet-of-Things port number and processes the Internet-of-Things data packet based on the sensor identifier;
allocate a virtual sub-card identifier for the Internet-of-Things sensor; and
send a first correspondence between the virtual sub-card identifier corresponding to the Internet-of-Things sensor and an interface identifier of an interface connected with the Internet-of-Things sensor on the AP to the AC such that the AC generates a topology of the AP and a virtual sub-card based on the first correspondence.

5. The AP according to claim 4 , wherein the processor is caused by the machine-executable instructions further to:
generate a second correspondence between the sensor identifier of the Internet-of-Things sensor and the virtual sub-card identifier corresponding to the Internet-of-Things sensor,
the processor is caused by the machine-executable instructions to:
determine a corresponding virtual sub-card identifier based on the second correspondence and the sensor identifier carried in the Internet-of-Things data packet; and
send the determined virtual sub-card identifier and the Internet-of-Things data packet to the AC such that the AC performs management for the Internet-of-Things sensor based on the virtual sub-card identifier and the topology of the AP and the virtual sub-card.

6. A machine-readable storage medium storing machine executable instructions which are invoked and executed by a processor to execute the method of processing a packet according to claim 1 .
