Heterogeneous multi-protocol stack method, apparatus, and system

A terminal, comprising:

• a storage that stores a protocol stack program, a first application, and a second application, wherein an application type of the first application is different from that of the second application;
• a communications subsystem configured to receive a first data packet;
• and
• an application processor that executes the protocol stack program to:
• create a first protocol stack instance and a second protocol stack instance,
• allocate resources to the first protocol stack instance and the second protocol stack instance, wherein a resource configuration of the first protocol stack instance is different from that of the second protocol stack instance, and wherein the resource configuration indicates a type of an allocated resource and a quota of each type of resource,
• determine, based on characteristic information of the data packet, a protocol stack instance that matches the data packet, and
• dispatch the data packet to the matched protocol stack instance, wherein the matched protocol stack instance is the first protocol stack instance or the second protocol stack instance.

A data processing method, comprising:

• creating a first protocol stack instance and a second protocol stack instance;
• allocating resources to the first protocol stack instance and the second protocol stack instance, wherein a resource configuration of the first protocol stack instance is different from that of the second protocol stack instance, and wherein the resource configuration indicates a type of an allocated resource and a quota of each type of resource;
• and wherein the first protocol stack instance is configured to process a data packet of a first-type application, and the second protocol stack instance is configured to process a data packet of a second-type application;
• determining, based on characteristic information of a data packet, a protocol stack instance that matches the data packet, and
• dispatching the data packet to the matched protocol stack instance, wherein the matched protocol stack instance is the first protocol stack instance or the second protocol stack instance.
