Abstract
Embodiments of this application provide a communication method, a device, and a system, to resolve an out-of-order problem caused by per-packet traffic splitting. The method includes: determining, by a sending device, a sequence identifier of a to-be-transmitted data packet and an identifier of a first link for transmitting the data packet; and sending, by the sending device, the data packet to a receiving device, where a header of the data packet includes the identifier of the first link and the sequence identifier, the identifier of the first link is used to identify the first link, and the sequence identifier is used to identify a sending order of the data packet over the first link or in a link group to which the first link belongs.
Claims24
A communication method, comprising:
- determining, by a sending device, a sequence identifier of a data packet to-be-transmitted and an identifier of a first link for transmitting the data packet, wherein the sequence identifier identifies a sending order of the data packet in a link group to which the first link belongs, and the identifier of the first link identifies the first link;
- wherein determining the identifier of the first link for transmitting the data packet, comprises:
- determining, based on a 5-tuple of the data packet, a service flow identifier, wherein the service flow identifier identifies a service flow to which the data packet belongs;
- determining, based on a correspondence between the service flow identifier and identifiers of a plurality of links in the link group, the identifier of the first link for transmitting the data packet;
- and
- sending, by the sending device, the data packet to a receiving device, wherein a header of the data packet comprises the identifier of the first link and the sequence identifier.
A sending apparatus, comprising:
- a processor configured to:
- determine a sequence identifier of a to-be-transmitted data packet, and
- determine an identifier of a first link for transmitting the data packet, wherein the sequence identifier identifies a sending order of the data packet in a link group to which the first link belongs, and the identifier of the first link identifies the first link;
- wherein determining the identifier of the first link for transmitting the data packet, comprises:
- determine, based on a 5-tuple of the data packet, a service flow identifier, wherein the service flow identifier identifies a service flow to which the data Packet belongs;
- determine an identifier of a first link for transmitting the data packet based on a correspondence between a service flow identifier and identifiers of a plurality of links in the link group, the identifier of the first link for transmitting the data packet;
- and
- a transceiver configured to send the data packet to a receiving device, wherein a header of the data packet comprises the identifier of the first link and the sequence identifier.
A system, comprising:
- a receiving device, and
- a sending device, comprising:
- a processor configured to:
- determine a sequence identifier of a to-be-transmitted data packet and an identifier of a first link for transmitting the data packet, wherein the sequence identifier identifies a sending order of the data packet in a link group to which the first link belongs, and the identifier of the first link identifies the first link;
- wherein determining the identifier of the first link for transmitting the data packet, comprises:
- determine, based on a 5-tuple of the data packet, a service flow identifier, wherein the service flow identifier identifies a service flow to which the data packet belongs;
- determine based on a correspondence between a service flow identifier and identifiers of a plurality of links in the link group, the identifier of the first link for transmitting the data packet;
- and
- a transceiver configured to send the data packet to the receiving device, wherein a header of the data packet comprises the identifier of the first link and the sequence identifier.
A communication method, comprising:
- determining, by a sending device, a sequence identifier of a data packet to-be-transmitted and an identifier of a first link for transmitting the data packet, wherein the sequence identifier identifies a sending order of the data packet in a link group to which the first link belongs, and the identifier of the first link identifies the first link;
- wherein determining the identifier of the first link for transmitting the data packet, comprises:
- determining, based on a 5-tuple of the data packet, a service flow identifier, wherein the service flow identifier identifies a service flow to which the data packet belongs;
- determining based on a correspondence between the service flow identifier and identifiers of a plurality of links in the link group, the identifier of the first link for transmitting the data packet;
- sending, by the sending device, the data packet to a receiving device, wherein a header of the data packet comprises the identifier of the first link and the sequence identifier;
- and
- receiving, by the receiving device, the data packet from the sending device.
