Embodiment 1

[0033] figure 1 It is a schematic diagram of an application of a cloud platform physical link connectivity detection system according to an embodiment of the present invention. The cloud platform includes multiple computing nodes (only two are shown in the figure), and multiple virtual machines run on each computing node. The east-west service traffic of each computing node interacts through the data network card on the server.

[0034] figure 2 It is an architecture diagram of a cloud platform physical link connectivity detection system according to an embodiment of the present invention. A cloud platform physical link connectivity detection system is based on the Openstack cloud platform, using the Ceilometer module to complete the data interaction between the ovs and the control node, thereby realizing the cloud platform physical link connectivity detection. The Ceilometer module includes an agent module (Ceilometer-polling-agent) installed on the computing node side an...

Embodiment 2

[0046] image 3 It is a schematic flow diagram of a method for detecting the connectivity of a cloud platform physical link in an embodiment of the present invention, and the detection method includes steps:

[0047] S11. Send the message to neutron through the Restful api (RepresentationalState Transfer ful api) interface after receiving the detection instruction through Horizon.

[0048] S12. After receiving the detection instruction, Neutron obtains the corresponding segment id (ie, vlan id) and the fe80 local data port address of the opposite end from the database, and sends the obtained message to the Neutron-ovs of the computing node to be detected through rpc -agent.

[0049] S13, after the Neutron-ovs-agent obtains the corresponding detection instruction and the message, it sends the message to the Ovs through the restful api.

[0050] S14, the Ovs receives the detection message and the destination ip message, sends ping packets sequentially according to the range of...

Embodiment 3

[0058] A cloud platform physical link connectivity detection method, the method is executed by a computing node device, the detection method comprising:

[0059] S21. The Neutron-ovs-agent component receives the detection command sent by the control node and the vlan range of the data network to be detected, and sends the detection command and the vlan range of the data network to be detected to the Ovs component.

[0060] S22, the Ovs communication module sends an icmp request message to the vlan range of the data network to be detected, receives the icmp reply message sent by the vlan range of the data network to be detected, determines the detection result information of the vlan range of the data network, and sends the detection result information Stored in the Ovs database.

[0061] Determine which virtual network ranges can be connected according to whether the reply packet is received within the predetermined time, that is, the virtual network range that can receive the...

Abstract

The invention provides a computing node device, a control node device, a method and a system for cloud platform physical link connectivity detection. The computing node device comprises a Neutron-ovs-agent component, an Ovs component and a Ceilometer-poly-agent component, wherein the Neutron-ovs-agent component is used for storing the Ceilometer-poly-agent component into the Ovs component; the Ovscomponent detects whether the vlan range of the data network is connected or not in a mode determined by sending an icmp request message according to the vlan range of the virtual network to be detected; and the Ceilometer-poly-agent component is used for acquiring detection result information from a database corresponding to the Ovs component, and sending the detection result information to thecontrol node. According to the invention, the automatic connectivity detection on the data network card between the computing nodes in the dpdk scene can be realized, and the stability and security ofthe network are enhanced.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a device, method and system for detecting connectivity of a physical link of a cloud platform. Background technique [0002] With the advent of the mobile Internet era, network function virtualization is a trend in current networking development. Major operators have increased their investment in network function virtualization, and cloud computing technology has been widely used in various technical fields. In the network scenario where computing nodes are deployed on a large scale, since the business is running on each computing node, the east-west business traffic between virtual machines is exchanged through the data network card on the server. Therefore, it is necessary to use the cloud computing service before Test whether the network is normal. In the context of large-scale cloudification of services, how to detect the connectivity between service network ports of...
