1. A packet transmission method, comprising:
establishing, by a target transport layer proxy network element, a fourth transport layer connection based on a first context of a source transport layer proxy network element, wherein the first context is a context about packet transmission of the source transport layer proxy network element on a first path; and
when the target transport layer proxy network element receives first indication information, and the first indication information is used to indicate that application context migration between a first application server and a second application server is completed, performing, by the target transport layer proxy network element, transport layer processing on a packet on a second path based on a second context of the target transport layer proxy network element, and transmitting, on the second path, a packet obtained through the transport layer processing, wherein the second path comprises a third transport layer connection and the fourth transport layer connection; the second context is determined based on the first context and the fourth transport layer connection; when the application context migration is being performed, packet transmission between the first application server and a transport layer proxy network element is stopped; and the transport layer proxy network element comprises the source transport layer proxy network element or the target transport layer proxy network element, wherein
the first path is a path established between a terminal device and the first application server, the first path comprises a first transport layer connection and a second transport layer connection, the first transport layer connection is a transport layer connection between the source transport layer proxy network element and the terminal device, the second transport layer connection is a transport layer connection between the source transport layer proxy network element and the first application server, the third transport layer connection is a transport layer connection between the target transport layer proxy network element and the terminal device, and the fourth transport layer connection is a transport layer connection between the target transport layer proxy network element and the second application server.
