Description

Communication method and network equipment

Technical Field

The embodiment of the application relates to the field of communication, in particular to a communication method and network equipment.

Background

A node is a connection point and represents a redistribution point (redistribution point) or a communication endpoint. The definition of a node generally depends on the mentioned network and protocol layers, and the node referred to in the embodiments of the present application generally refers to a terminal device. An access component, typically comprising a container and applications such as virtual machines for implementing certain functions, may be deployed on top of a node. A network plane, generally refers to a network established between a plurality of nodes for communication, and is established by means of at least one node.

Under the environment of the virtual network, a virtualized management platform is deployed on the working node. When a user needs some access components to provide services, the virtualization management platform receives application requests of the access components. The virtualized management platform, upon receiving an access component application request, may establish a network plane between a plurality of nodes deploying the access component. For example, kubernetes (K8S) can implement simple interconnection between a plurality of nodes deploying the POD assembly after receiving an application request of the POD assembly, so that the nodes deploying the POD assembly can provide communication services for users by running the POD assembly.

After the virtualized management platform realizes simple interconnection among the nodes of the plurality of deployment access components, the virtualized management platform has limited management capability and cannot reasonably manage and control the communication services provided by the access components. For example, when there is a need for flow control, monitoring metrics, etc. for communication services provided by the access component, the virtualization management platform cannot handle the communication services.

The selection node selects the working node meeting the condition to establish the network plane, the selection node and the management node can be the same equipment, the selection node and the management node can also be different equipment, and the method is not limited in detail herein.

The communication method provided in the embodiment of the present application is described based on the communication system described in fig. 1.

Referring to fig. 2, an embodiment of a communication method in the embodiments of the present application includes steps 201 to 203.

201. The first working node receives an access request.

The first working node is a device with an operating system installed. Alternatively, the first working node may be a terminal device, and the first working node may also be a server, and the first working node may also be other devices, which is not limited herein.

The access request is for instructing the first working node to access the access component into the network plane. Alternatively, the access component may be a virtual machine or a virtual container created on the first working node, or may be another process created on the first working node, which is not limited herein.

202. The first working node sets a corresponding first virtual interface for the access component.

The access component needs to access the network plane before it can communicate with other working nodes in the network plane. The first working node may set a corresponding first virtual interface for the access component, through which the access component may communicate with the second working node in the network plane.

203. The first working node manages communication services of the access component through the first virtual interface.

The access component accesses the network plane through the first virtual interface such that the first working node can manage communication services of the access component by configuring the first virtual interface.

The setting of the corresponding first virtual interface for the access component by the first working node mentioned in step 202 may be implemented by allocating a virtual network card and an IP address, where the implementation manner includes: the first working node uses the side car component to allocate a virtual network card for providing a virtual interface function for the access component, and a first IP address for supporting communication of the virtual network card.

Fig. 3 is a schematic diagram of an embodiment of a communication method according to an embodiment of the present application.

Referring to FIG. 3, an exemplary work node has a virtualization management platform, such as Kubernetes (K8S), deployed thereon, and a sidecar assembly (sidecar) deployed thereon. The access component is a POD component. The sidecar comprises at least three components: drive, control plane and data plane. The management node is deployed with a K8S master. The main function of driver is to interact with K8S. For example, one function of driver is to monitor the creation of various resources in K8S all the time. The driver then forwards the monitoring information to the control plane, whose main function is to handle the request for the establishment of the plane and the request for the POD component to access the plane. The function of the dataplane is to establish the network plane and to establish a connection between the POD component and the network plane.

Fig. 3a is a schematic diagram of an embodiment of a communication method according to an embodiment of the present application.

Referring to fig. 3a, the access device is a POD device. The user will first send a POD component access request to the management node. After receiving the POD component access request, the management node sends the access request to drivers in the sidecar installed on the first working node. After receiving the access request, the driver sends the access request to the control plane in the sidecar. After the control plane in the first working node receives the access request of the POD component, the control plane may send the access request to the dataplane. In this way, the first working node may allocate a virtual network card and an IP address to the POD component using the dataplane in the sidecar component, where the virtual network card and the IP address combine to form the first virtual interface.

Fig. 4 is a schematic diagram of another embodiment of the communication method provided in the embodiment of the present application.

Referring to fig. 4, alternatively, an access component on a working node may access a network plane through a virtual interface, for example, an access component POD1 on a first working node accesses a network plane2. Multiple PODs on one working node may access one network plane through a virtual interface, e.g. access component POD2 and access component POD3 on a second working node access network plane2. An access component on one working node may also access different network planes, e.g. the access component POD4 on the third working node accesses the network plane1 and the network plane2 via different virtual interfaces. The access component may also access into the network plane in other ways, and is not limited in particular herein.

The first working node mentioned in step 203 has a plurality of different implementations for managing the communication service of the access component through the first virtual interface, and these different implementations can be understood with reference to the following three points.

1. The first working node controls the transmission rate of the transmission flow of the corresponding access component to be smaller than a first threshold value through the first virtual interface.

The first threshold is a maximum transmission rate of transmission traffic of a corresponding access component configured by the first working node. The traffic transmitted between the network plane and the access component needs to be transmitted through the first virtual interface, so that the first working node can set the maximum transmission rate of the traffic transmitted by the first virtual interface, and further, the first working node can indirectly control the traffic of the corresponding POD access component through the first virtual interface.

Illustratively, a virtualized management platform, such as K8S, is deployed on the working node, a sidecar is also deployed on the first working node, and the access component is a POD component. Firstly, the sidecar establishes a virtual interface named eth2 for the POD component, and the upper limit of the transmission rate is 1 megabit/second, thereby realizing the control of the transmission rate of the corresponding flow of the POD component. The transmission rate includes a sending rate and a receiving rate, which are not limited herein.

Optionally, the datacard has a virtual transmission interface corresponding to the first virtual interface corresponding to the POD component, where the virtual transmission interface is assumed to be named as eth2-peer, so the first working node only needs to set the upper limit of the transmission rate of eth2-peer to be 1 megasecond, and then the upper limit of the receiving rate of eth2 is 1 megasecond. Taking openvswitch as an example, after the eth2-peer is established, we send a command to the openvswitch in the program: ovs-vsctl set interface tap ingress_poling_rate=1000. Thus, control of the upper limit of the eth2-peer transmission rate of 1 megabit/second is realized. In the above embodiments, the control eth2 interface and the control eth2-peer interface are merely taken as examples for illustration, and other implementations are also possible in practical applications, and are not limited in this specific application.

2. The first working node controls the transmission rate of the transmission flow of the corresponding access component to be larger than a second threshold value through the first virtual interface.

The second threshold is a minimum transmission rate of transmission traffic of the corresponding access component configured by the first working node. The traffic transmitted between the network plane and the access component needs to be transmitted through the first virtual interface, so that the first working node can set the minimum transmission rate of the traffic transmitted by the first virtual interface, and further, the first working node can indirectly control the traffic of the corresponding POD access component through the first virtual interface.

Illustratively, a virtualized management platform, such as K8S, is deployed on the working node, a sidecar is also deployed on the first working node, and the access component is a POD component. Firstly, the sidecar establishes a virtual interface named eth3 for the POD component, and the lower limit of the transmission rate is 1 megabit/second, thereby realizing the control of the transmission rate of the corresponding flow of the POD component. The transmission rate includes a sending rate and a receiving rate, which are not limited herein.

Optionally, the datacard has a virtual transmission interface corresponding to the first virtual interface corresponding to the POD component, where the virtual transmission interface is assumed to be an eth3-peer, so that the first working node only needs to set a lower limit of a transmission rate of eth3-peer to be limited to 1 megasecond, and then the lower limit of a receiving rate of eth3 is naturally limited to 1 megasecond.

3. And the first working node counts the transmission flow of the corresponding access component through the first virtual interface.

Illustratively, a virtualized management platform, such as K8S, is deployed on the working node, a sidecar is also deployed on the first working node, and the access component is a POD component. Since the traffic of all interfaces in the POD passes through the dataplane in the sidecar, the traffic of the POD assembly can be counted only by counting the traffic of the virtual interfaces corresponding to the POD assembly in the dataplane. Taking openvswitch as an example, the dataplane only needs to deploy an sFlow Agent and an sFlow collector and start the sFlow in the openvswitch of the first working node to be monitored to count the transmission flow of the POD component because the openvswitch has the sFlow function. In the above embodiment, only the open sFlow in the openvswitch is used to describe the statistics of the transmission flow of the POD assembly, and other implementations are also possible in practical applications, which are not limited in this specific embodiment.

In the foregoing embodiments, other implementations besides the three different implementations described above are alternatively possible, and are not limited herein.

In this embodiment, optionally, before the first working node receives the access request, the first working node may also establish a network plane, and a process of establishing the network plane will be described in detail in the following embodiments.

Referring to fig. 5, fig. 5 is a schematic diagram of an embodiment of a communication method according to the present disclosure.

301. The first working node obtains a first establishment request.

The first set-up request may be for requesting the first working node to establish a network plane with the second working node. After receiving the plane establishment request sent by the user equipment, the management node may acquire the first establishment request by the working node. The first establishment request may include parameters required by the first working node to establish the network plane. For example, virtual extended lan identifier (VXLAN network identifier, VNI), id of VXLAN tunnel when the network plane crosses nodes, vlan id used by the network plane inside one node, number of nodes needed to be used for establishing the network plane, and other parameters, such as receiving rate of the network plane, etc., which are not limited herein.

The first setup request is used herein for illustration purposes to request the first working node to establish a network plane with the second working node. Alternatively, the first establishment request may be used to request the first working node to establish a network plane with some other working node than the second working node. The first establishment request may be used to request the first working node to establish a network plane with at least two working nodes, and is not limited herein.

Illustratively, if the parameters required to establish the network plane include a constraint, the constraint is: the receiving rate of the network plane is not less than 1000kb/s. If the first working node confirms that the first working node has the capability of configuring the network plane receiving rate and can realize that the network plane receiving rate is not less than 1000kb/s, the first working node confirms that the first working node meets the limiting condition included in the parameters required for establishing the network plane, namely, the first working node meets the second condition for establishing the network plane with the second working node.

Illustratively, if the parameters required to establish the network plane include a constraint, the constraint is: the minimum number of central processing units (central processing unit, CPU) of the working node that establishes the network plane is 3. If the first working node confirms that the first working node is provided with more than 3 CPUs, the first working node confirms that the first working node meets the limiting conditions included in parameters required for establishing the network plane, namely, the first working node meets the second condition for establishing the network plane with the second working node.

Alternatively, the above description is given by taking the limitation condition that the receiving rate of the network plane is not less than 1000kb/s and the minimum number of CPUs of the working node for establishing the network plane is 3 as an example, and the limitation condition included in the parameters required for establishing the network plane may also be other limitation conditions, which is not limited herein.

The K8S and the sidecar are only used as an example for the first working node deployment, and the first port number and the second IP address may be obtained by other manners, which is not limited herein.

Referring to fig. 5a, an exemplary working node has a virtualization management platform, e.g., K8S, deployed thereon, and a sidecar deployed on a first working node. The sidecar includes driver, controlplane and dateplane. After the driver in the sidecar obtains the first establishment request, the driver obtains the first port number and the second IP address according to the port identifier of the first port in the first establishment request. The driver may issue the obtained first port number and the second IP address to the control plane, and then the control plane may send a second establishment request to the selection node according to the first port number and the second IP address.
