Problems solved by technology

[0004] However the message is in figure 1 In the overlay network transmission process shown, that is, in the transmission process after the edge device encapsulates the received message, the quality of service (Quality of Service, Qos) of the transmission path is not considered, such as delay, jitter, Packet loss rate, etc., as long as the IP layer thinks that it is reachable, the routing path is considered to be available, but in fact, the IP layer thinks that the reachable routing path is not enough to carry the transmission of the message

Embodiment Construction

[0051] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0052] Hereinafter, some terms in the embodiments of the present application will be explained so as to be understood by those skilled in the art.

[0053] (1) Software Defined Network (SDN), such as figure 2 As shown, the typical architecture of SDN is divided into three layers, the top layer is the application layer (Applicaiton Layer), including various applications, network simulation, network planning, etc. The middle layer is the control layer, which is mainly responsible for the arrangement of data plane resources, the maintenance of network topology and state information, etc. The bottom layer is the network device layer (Infrastructure Layer), which is mainly responsible for data processing, forwarding and state collection base...

Abstract

A routing method and device are used to provide routing paths that meet QoS requirements. Wherein, a routing method includes: a first routing node performs QoS measurement on a path between reachable adjacent routing nodes, and obtains a set of QoS parameters for each path between two adjacent routing nodes; the first routing node The QoS parameter set is reported to the control node, so that the control node calculates the routing path from the first routing node to other routing nodes according to the QoS parameter set; the first routing node receives information from the control node. One or more routing tables issued by the first routing node to the other routing nodes; the first routing node receives the message, and determines from the one or more routing tables that the message is related to the message The routing table corresponding to the identifier, and forwards the received message according to the routing table.

Description

technical field [0001] The present application relates to the field of network technologies, and in particular, to a routing method and device. Background technique [0002] In the field of network technology, the traditional overlay network is a virtualization technology mode superimposed on the network architecture. Realize the bearer of the application on the network, and can be separated from other network services. The usual implementation is to encapsulate the data packet at the beginning of the tunnel in another data packet, and then forward the encapsulated packet to the end of the tunnel and then decapsulate it. For end systems connected outside the overlay edge device, the physical network is transparent, that is, for end systems, the end systems do not need to know the deployment of the physical network. [0003] See figure 1 , an overlay network is logically divided into two planes, the control plane, which is mainly responsible for the establishment and maint...
