Referring to fig. 1 and fig. 2, fig. 1 is a flowchart of a tunnel coordination method in an embodiment of the present invention, and fig. 2 is a schematic diagram of a system architecture of a hybrid overlay in the embodiment of the present invention, where the method may be applied to the system shown in fig. 2, and the method includes the following steps:
s101, acquiring host endpoint information of a host tunnel endpoint by using the tunnel cooperation plug-in, and sending the host endpoint information to a switch endpoint.
The tunnel collaboration plug-in may specifically refer to a plug-in of openstack neutron. The openstack indicates a source cloud computing platform management platform project. Neutron refers to a network structure including an external network, an internal network, and a router. The external network is responsible for connecting to a network environment outside the OpenStack project, also known as public network, and unlike other networks, it is not just a virtual network, and more importantly, it means that the OpenStack network can be accessed and accessed by an external physical network, the external network may be a local area (Intranet) of an enterprise, and may also be the Internet (Internet), such a network is not directly managed by Neutron, and the internal network is completely defined by software, also known as private network. It is the network in which the virtual machine instance resides, and can be directly connected to the virtual machine. Project users may create their own internal networks. By default, the internal networks between items are isolated from each other and cannot be shared. The network is configured and managed directly by Neutron. The router is used to connect an internal network with an external network. The main ones that Neutron needs to implement are internal networks and routers. The internal network is an abstraction of the two-layer (L2) network, emulating the two-layer local area network of the physical network, which is private to the project. The router is an abstraction of the three-layer (L3) network, and simulates a physical router to provide services such as routing and NAT for users.
The host tunnel endpoint (referred to as a host endpoint for short herein) may specifically refer to a node managed by openstack and having a tunnel creation capability. For example, openvswitch-agent node.
A switch endpoint (implemented by hardware and capable of implementing tunnel encapsulation), also called an SDN switch tunnel endpoint, may specifically refer to a third-party hardware SDN, is not managed by Openstack, but has a tunnel creation capability and needs a node that performs tunnel communication with a host endpoint. Such as SDN managed switches, etc. The sdn (software Defined network), a novel network innovation architecture of the Emulex network, is an implementation manner of network virtualization, and the core technology OpenFlow separates a control plane and a data plane of a network device, thereby implementing flexible control of network traffic and making the network as a pipeline more intelligent.
The tunnel driver plug-in may obtain host endpoint information for a host tunnel endpoint and send the host endpoint information to a switch endpoint. The host endpoint information may specifically include: tunnel type (e.g. vxlan), tunnel endpoint IP, tunnel endpoint hostname, and of course, depending on the tunnel type, a tunnel endpoint port may also be included. Specifically, when sending host endpoint information to a switch endpoint, this can be achieved by invoking a tunnel driver.
In a specific embodiment of the present application, the step S101, using a tunnel collaboration plug-in to obtain host endpoint information of a host tunnel endpoint, and sending the host endpoint information to a switch endpoint, includes:

and step two, calling tunnel synchronization ports of all the tunnel cooperative drives, and sending the full-amount host endpoint information to the software-defined network controller so that the software-defined network can forward the full-amount host endpoint information to the switch endpoint.
That is to say, the tunnel collaboration plug-in can issue the full amount of host endpoint information to the tunnel collaboration drive periodically, so as to perform information verification when data inconsistency occurs in some unknown or complex situations. The specific implementation mode is as follows: when the tunnel collaboration plug-in is started, registering a periodic task and synchronizing endpoint information; the tunnel collaboration plug-in inquires data to sense the full host endpoint information of all host endpoints; sequentially calling tunnel _ sysnc interfaces cooperatively driven by all tunnels; and the cooperative drive plug-in receives the full-amount host endpoint information and informs the SDN controller. And the SDN controller performs more-less compensation on the repeated endpoint information.

For the existing plug-in/driver of the control node, specific definitions and functions of the existing plug-in/driver may be referred to, and detailed description is omitted here.
The specific implementation process comprises the following steps:
step one, registering a tunnel collaborative drive to a software defined network;
and step two, registering the tunnel collaboration plug-in to a cloud computing platform management platform.
It should be noted that when the switch endpoint is specifically a third-party hardware SDN, after the configuration file corresponding to the network service plug-in of the cloud computing platform management platform is modified, the tunnel collaboration plug-in is loaded.
That is, Openstack is responsible for implementing the tunnel collaboration plug-in. Service _ plug entries _ point (to implement a registration point loaded in name form). When this functionality is needed, the plugin is loaded by modifying the configuration file of the neutron-server.
The SDN is responsible for realizing tunnel cooperative driving. The tunnel collaboration driver is registered to neutron. tc _ drivers entry _ point (to implement a registration point loaded in the form of a name). And the tunnel collaboration plug-in selects a loading driver according to the configuration. The cooperative driving is realized according to the attribute and interface design, and can be an independent code library.

Specifically, the tunnel collaboration plug-in periodically pulls the endpoint information of the full-scale switch, compares the difference and informs the host endpoint. The specific implementation mode is as follows: when the tunnel collaboration plug-in is started, registering a periodic task to pull the endpoint information of the switch, and calling all the tunnel collaboration drivers in sequence to acquire the endpoint information of the switch; and comparing the difference and issuing the change.
In the first step, the tunnel cooperative drive is used to obtain the full-scale switch endpoint information of all the switch endpoints, which may specifically include: calling the tunnel endpoint attribute in the tunnel collaborative drive to obtain each return list; the list element number is a dictionary, switch endpoint information is included in the dictionary, and the switch endpoint information includes: tunnel type, tunnel endpoint IP, tunnel endpoint hostname, tunnel endpoint port.

The endpoint information includes: the type of the tunnel: tunnel _ type ═ vxlan; and (3) tunnel endpoint IP: ip _ address; tunnel endpoint hostname: host (guaranteed unique); tunnel endpoint port: port (according to tunnel type, may not be present). Wherein: the tunnel type may be in the support _ channel _ types list.

S103, tunnel connection is established between the host tunnel endpoint and the switch endpoint by utilizing the host endpoint information and the switch endpoint information, so that the host tunnel endpoint and the switch endpoint can carry out tunnel communication through the tunnel connection.
After the switch end point and the host tunnel end point complete mutual sensing, tunnel connection can be established between the host tunnel end point and the switch end point by utilizing the host end point information and the switch end point information. After the tunnel connection is established, tunneling between the host tunnel endpoint and the switch endpoint may occur over the tunnel connection. Namely, the hybrid overlay can be realized among cross-producer devices.
In one embodiment of the present application, updates, creation, and overflow of host tunnel endpoints are also effectively sensed and related notifications are completed. The specific implementation process comprises the following steps:
monitoring a host terminal agent in a host tunnel endpoint;
and step two, when at least one of the updating behavior, the creating behavior and the removing behavior is monitored, the tunnel cooperative drive is called, and the updating, removing and creating messages of the host tunnel endpoint are sent to the switch endpoint.
Namely, the tunnel cooperative plug-in can detect the addition of a new host tunnel endpoint and issue the new host tunnel endpoint to the cooperative drive. The specific implementation mode is as follows: the tunnel collaboration plug-in monitors Agent creation behaviors; and receiving the creation notification, sequentially calling the create _ tunnel interfaces of all the collaborative drivers, receiving the endpoint information by the collaborative driver plug-in, and notifying the SDN controller.
And the tunnel cooperative plug-in can detect the update of the tunnel endpoint of the host and send the update to the cooperative drive. The specific implementation mode is as follows: the tunnel is cooperated with the plug-in unit to monitor the update behavior of the Agent; receiving the update notification, and sequentially calling the update _ tunnel interfaces of all the cooperative drives; and the cooperative drive plug-in receives the endpoint information and informs the SDN controller.

The specific implementation mode is as follows: the tunnel is cooperated with the plug-in unit to monitor the Agent removal behavior; receiving the removal notification, and sequentially calling delete _ tunnel interfaces of all the cooperative drives; and the cooperative drive plug-in receives the endpoint information and informs the SDN controller.
Wherein the SDN controller may process the duplicate endpoint information.
