Abstract
The present disclosure provides a transmission control method, a node, a network system, and a storage medium. The transmission control method includes encapsulating, by a node, overlay service identification information corresponding to a packet in the packet, and transmitting, by the node, the packet to a next hop using an underlay network resource dedicated to a service corresponding to the overlay service identification information.
Claims18
A transmission control method, comprising:
- encapsulating, by a node, overlay service identification information corresponding to a packet in the packet, and transmitting, by the node, the packet to a next hop using an underlay network resource dedicated to a service corresponding to the overlay service identification information,
- wherein the step of encapsulating the overlay service identification information corresponding to the packet in the packet comprises:
- encapsulating a slice label and the overlay service identification information in a label stack of the packet according to a Forwarding equivalence class To Next hop label forwarding entry map (FTN) entry hit by the packet;
- wherein the slice label refers to a multiprotocol label switching (MPLS) label with slicing capability allocated to a slice forward equivalence class (FEC).
A transmission control method, comprising:
- when a node receives a packet, forwarding, by the node, the packet using an underlay network resource dedicated to a service corresponding to overlay service identification information carried in the packet,
- wherein the overlay service identification information is carried in a label stack of the packet, and a position of the overlay service identification information in the label stack and a position of a slice label, which is in an incoming label map (ILM) entry hit by the packet, in the label stack satisfy a preset relationship,
- wherein the slice label refers to a multiprotocol label switching (MPLS) label with slicing capability allocated to a slice forward equivalence class (FEC).
A network system, comprising an ingress node, at least one intermediate node, and an egress node, wherein:
- the ingress node is configured to encapsulate overlay service identification information corresponding to a packet in the packet, and transmit the packet to a next hop using an underlay network resource dedicated to a service corresponding to the overlay service identification information;
- the intermediate node is configured to forward, when receiving a packet, the packet using an underlay network resource dedicated to a service corresponding to overlay service identification information carried in the packet;
- and
- the egress node is configured to forward, when receiving a packet, the packet using an underlay network resource dedicated to a service corresponding to overlay service identification information carried in the packet,
- wherein the encapsulating, by the ingress node, the overlay service identification information corresponding to the packet in the packet comprises:
- encapsulating the overlay service identification information in a label stack of the packet, with a position of the overlay service identification information in the label stack and a position of a slice label, which is in an FTN entry hit by the packet, in the label stack satisfying a preset relationship, wherein the slice label refers to a multiprotocol label switching (MPLS) label with slicing capability allocated to a slice forward equivalence class (FEC).
