Method for generating forwarding table entry, controller and network device

Abstract

The present application discloses a method for generating a forwarding table entry and a network device. The method comprises that a controller sends a plurality of resource allocation request messages to a plurality of network devices in a network fragment to trigger the network devices to allocate resources according to the resource allocation request messages, wherein the resource allocation request message include the identifier of the network fragment and a resource required to be allocated to the network fragment by the corresponding network device; the controller receives a plurality ofresource allocation response messages, wherein the resource allocation response message includes the identifier of the network fragment and the segment identifier of the corresponding network device,the resource allocated by each device belongs to the network fragment; the controller generates a forwarding table corresponding to the network fragment according to the resource allocation responsemessages, wherein the forwarding table includes the forwarding table entry reaching the network devices of the network fragment, and the forwarding table entry includes a segment identifier reaching adestination network device. The forwarding table entry helps to provide a user with a flexible message forwarding way based on network fragment resource isolation.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for generating a forwarding entry, a controller and a network device. Background technique [0002] The vision of 5G (5th generation mobile networks) network is to support a variety of new services, such as virtual reality (virtual reality, VR), augmented reality (augmented reality, AR), remote industrial control, automatic Driving and IoT etc. Since different types of services have very different requirements on the network, 5G proposes to divide different logical network segments on the same physical network through network slicing to meet the differentiated needs of different services. For the operator network, network slicing requires the operator network to provide network connections between the core network, access network and various service functions that meet the needs of users and different services. The network sharding provides differentiated and guaranteed quali...
