Embodiments of the present disclosure provide a network logical layering method based on Routing In Fat Tree (RIFT) protocol, a network logical layering device, a network device and a storage medium. By exchanging Link Information Element (LIE) packets and Topology Information Element (TIE) packets with other devices, a network device can enable the other devices in the network to know a topology supported by the present device and to know neighbor information and Metric information of the present device in the supported topology, and the network device can also know the topologies supported by the other devices in the network and the neighbor information and the Metric information of the other devices in the corresponding topologies. Thus, the device can calculate a topology route corresponding to the topology supported thereby.

RIFT protocol-based network logical layering method and device, network device and storage medium

A protocol processing method and apparatus, and a storage medium are provided. The method includes: carrying a leaf-transfer capability identifier in an RIFT protocol, the leaf-transfer capability identifier being configured to indicate that a first node that carries the leaf-transfer capability identifier supports other leaf nodes within a network to access the network through the first node.

Protocol processing method and storage medium

Provided is a method for forwarding service data, a network device, and a network system. The forwarding method may include the following operation. A forwarding path for service data is determined according to network resource configuration information of a designated network and a network slice of the service data, wherein the network resource configuration information indicates one or more network slices associated with one or more network resources of the designated network, and a network slice associated with a network resource of the determined forwarding path matches the network slice of the service data; and the service data is forwarded according to the forwarding path.

Method for forwarding service data, network device, and network system

The present invention provides a packet forwarding method and device. The method comprises: a first node receiving a packet for forwarding, wherein a destination address of the packet is a second node; the first node identifying, from topologies generated in advance, a target topology corresponding to the packet, wherein the topologies generated in advance comprise a first topology and a second topology generated according to an MRT algorithm, and a third topology obtained according to an SPF algorithm, wherein the first topology, the second topology and the third topology are different from one another; and the first node identifying, from the target topology, a next hop node for forwarding to the second node, and forwarding the packet to the next hop node. The present invention achieves an object of combining a segmented routing network and an MRT function.
