1. A traffic routing method, comprising:
receiving a routing rule from a session management network element in a session management process, wherein the routing rule indicates at least one of the following:
to send a first traffic to a first function entity, or
to send a second traffic to a second function entity or an access device, wherein the first traffic is a traffic on which first traffic steering control is to be performed, and the second traffic is a traffic on which the first traffic steering control has been performed;
wherein the traffic on which first traffic steering control is to be performed is a traffic that has not been processed by a service function on a mobile edge computing (MEC) platform, the traffic on which the first traffic steering control has been performed is a traffic that has been processed by the service function on the MEC platform, the first function entity is for communicating with the MEC platform, the second function entity is for communicating with a central data network, and wherein the first traffic is a downlink traffic that is in a session and that is from the central data network, or the second traffic is an uplink traffic that is in the session; and
transmitting a received traffic according to the routing rule.
