Abstract
A label management method includes allocating, by a controller, a source label to a data stream, sending, by the controller, a first Border Gateway Protocol (BGP) update packet to an ingress network device on a label switching path (LSP) of the data stream, and sending a second BGP update packet to an egress network device on the LSP of the data stream, where the first BGP update packet includes a stream identifier of the data stream and the source label, and the second BGP update packet includes a mapping relationship between the source label and a source object of the data stream.
Claims20
An ingress network device on a label switching path (LSP) of a first data stream, comprising:
- a memory configured to store instructions;
- and
- a processor coupled to the memory and configured to execute the instructions to cause the ingress network device to:
- receive, from a controller, a source label indicating a source object associated with the first data stream;
- receive the first data stream;
- encapsulate the source label into the first data stream to produce a second data stream;
- and
- send the second data stream to an egress network device on the LSP.
A controller, comprising:
- a memory configured to store instructions;
- and
- a processor coupled to the memory and configured to execute the instructions to cause the controller to:
- allocate a source label to a data stream, wherein the source label indicates a source object associated with the data stream;
- and
- send the source label to an ingress network device on a label switching path (LSP) of the data stream.
An egress network device on a label switching path (LSP) of a data stream, comprising:
- a memory configured to store instructions;
- and
- a processor coupled to the memory and configured to execute the instructions to cause the egress network device to:
- receive the data stream from an ingress network device, wherein a source label is encapsulated in the data stream, and wherein the source label indicates a source object associated with the data stream;
- and
- identify the source object according to the source label.
