Abstract
Provided is a message decapsulation method and device, a message encapsulation method and device, an electronic device, and a storage medium. The message decapsulation method includes: a data packet sent by a first node is decapsulated, and the data packet is obtained by encapsulating, by the first node, a data message sent through a first Attachment Circuit (AC). The data packet carries split horizon attributes of the first AC determined by the first node. The split horizon attributes of the first AC include at least one of the following: a leaf attribute, a root attribute, and an Ethernet Segment Identifier (ESI) attribute.
Claims19
A message decapsulation method, applied to a second node, comprising:
- decapsulating a data packet sent by a first node;
- wherein, the data packet is obtained by encapsulating, by the first node, a data message sent through a first Attachment Circuit (AC), the data packet carries a split horizon attribute of the first AC determined by the first node, and the split horizon attribute of the first AC comprises at least one of the following:
- a leaf attribute, a root attribute;
- the leaf attribute or the root attribute indicates a node attribute of a user-side interface corresponding to the first AC in an E-Tree service;
- wherein a format of the data packet comprise one of the following:
- Generic Network Virtualization Encapsulation (Geneve), and Virtual Extensible Local Area Network Generic Protocol Extension (VXLAN-GPE).
A message encapsulation method, applied to a first node, comprising:
- determining a split horizon attribute of a first Attachment Circuit (AC), wherein the split horizon attribute of the first AC comprises at least one of the following:
- a leaf attribute, a root attribute;
- the leaf attribute or the root attribute indicates a node attribute of a user-side interface corresponding to the first AC in an E-Tree service;
- and
- encapsulating a data message sent through the first AC to obtain a data packet, and sending the data packet to a second node, wherein the data packet carries the split horizon attribute of the first AC;
- wherein a format of the data packet comprise one of the following:
- Generic Network Virtualization Encapsulation (Geneve), and Virtual Extensible Local Area Network Generic Protocol Extension (VXLAN-GPE).
A message decapsulation device, applied to a second node, comprising:
- a decapsulating module, configured to decapsulate a data packet sent by a first node;
- wherein, the data packet is obtained by encapsulating, by the first node, a data message sent through a first Attachment Circuit (AC), the data packet carries split horizon attribute of the first AC determined by the first node, and the split horizon attribute of the first AC comprise at least one of the following:
- a leaf attribute, a root attribute, and the leaf attribute or the root attribute indicates a node attribute of a user-side interface corresponding to the first AC in an E-Tree service;
- wherein a format of the data packet comprise one of the following:
- Generic Network Virtualization Encapsulation (Geneve), and Virtual Extensible Local Area Network Generic Protocol Extension (VXLAN-GPE).
