Data forwarding method and controller

A data forwarding method, wherein the method comprises:

• obtaining, by a controller, first identification information of a terminal, wherein the first identification information comprises terminal capability information, service type information, and quality of service QoS information of the terminal;
• determining, by the controller, N functional modules in L network nodes from M network nodes according to the first identification information, wherein the N functional modules are configured to process a data stream that corresponds to a service of the terminal;
• and
• configuring, by the controller for the L network nodes, corresponding forwarding entries for forwarding the data stream, wherein the forwarding entries are used to enable the L network nodes to process the data stream by using the N functional modules.

A controller, wherein the controller comprises:

• a processor, a bus, and a memory, wherein the processor obtains, by using the bus, an instruction stored in the memory, so as to:
• obtain first identification information of a terminal, wherein the first identification information comprises terminal capability information, service type information, and quality of service QoS information of the terminal;
• determine N functional modules in L network nodes from M network nodes according to the first identification information, wherein the N functional modules are configured to process a data stream that corresponds to a service of the terminal;
• and
• configure, for the L network nodes, corresponding forwarding entries for forwarding the data stream, wherein the forwarding entries are used to enable the L network nodes to process the data stream by using the N functional modules.
