Abstract
A method includes: sending, by a first device, a first bit stream to a second device, where the first bit stream is sent over N logical lanes of a physical layer of the first device; sending, by the first device, a first trigger marker group to the second device, where the first trigger marker group is used to indicate that the sending of the first bit stream ends; and sending, by the first device, a second bit stream to the second device in response to the sending of the first trigger marker group, where the second bit stream is sent over P logical lanes of the physical layer of the first device, and both N and P are positive integers.
Claims20
A method, comprising:
- sending, by a first device, a first bit stream to a second device, wherein the first bit stream is sent over N logical lanes of a physical layer of the first device;
- sending, by the first device, a first trigger marker group to the second device, wherein the first trigger marker group indicates that sending the first bit stream ends;
- and
- sending, by the first device, a second bit stream to the second device in response to the sending of the first trigger marker group, wherein the second bit stream is sent over P logical lanes of the physical layer of the first device, and both N and P are positive integers.
A communications device, comprising:
- a communications interface, configured to:
- send a first bit stream to a second device, wherein the first bit stream is sent over N logical lanes of a physical layer of the communications interface;
- send a first trigger marker group to the second device, wherein the first trigger marker group indicates that sending the first bit stream ends;
- and
- send a second bit stream to the second device in response to sending the first trigger marker group, wherein the second bit stream is sent over P logical lanes of the physical layer of the communications interface, and both N and P are positive integers.
A communications device, comprising:
- a communications interface, configured to:
- receive a first bit stream sent by a first device, wherein the first bit stream is received over N logical lanes of a physical layer of the communications interface;
- receive a first trigger marker group sent by the first device, wherein the first trigger marker group indicates that sending the first bit stream ends;
- and
- receive, after receiving of the first trigger marker group, a second bit stream sent by the first device, wherein the second bit stream is received over P logical lanes of the physical layer of the communications interface, and both N and P are positive integers.
