Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and in particular to a data frame transmission method, a virtualization platform and a storage medium. Background Art

[0002] Virtualized network elements usually use VLAN (Virtual Local Area Network) to identify their service interfaces. For example, different VLANs are used to distinguish network planes (such as management plane and service plane), service exports (such as to CMNET (China Mobile Network), IP bearer network, etc.), and interfaces between network elements (such as S-GW (Serving Gateway) / P-GW (PDN Gateway; PDN: Packet Data Network) interface and S-GW / MME (Mobility Management Entity) interface). In a virtualized environment, the appearance of this service feature is that the data frames sent by the virtual machine from the virtual port carry VLAN information. The virtualization platform needs to retain this "service VLAN" when forwarding data frames. Figure 1 The following is a schematic diagram of VNF (Virtualization Network Function) using VLAN to distinguish service interfaces. In the figure, vSwitch is a virtual switch, and SR-IOV is single root I / O virtualization (I / O: input / output). Figure 1 shown.

[0003] At the same time, the virtualization platform itself has tenant isolation capabilities. For the UNTAG (untagged) data frames sent by the virtual port, the virtualization platform needs to encapsulate a layer of VLAN header (traditional networking) or VxLAN (VLAN extension) header (SDN (Software Defined Network) networking) header to distinguish the communication traffic of different tenant virtual networks, and for the inbound data packets, the additional VLAN header or VxLAN header is reversely stripped and sent to the virtual port. The module that performs this action is usually the virtual machine switch (vSwitch) or network card (SR-IOV) of the virtualization platform. Figure 2 Schematic diagram of virtual network isolation for vSwitch and SR-IOV, as shown below Figure 2 shown.

[0004] Under normal circumstances, since the virtual network isolation mechanism of vSwitch and SR-IOV conflicts with the "business VLAN" of VNF, vSwitch and SR-IOV network cards will discard data packets with "business VLAN" when they receive data packets sent by the virtual port, resulting in abnormal network communication. Therefore, a solution is needed to implement transparent transmission of "business VLAN" to achieve normal business communication.

[0005] The disadvantage of the prior art is that the existing transparent transmission processing technical solution cannot be supported by the existing communication equipment unless the communication equipment is upgraded and modified. Summary of the invention

Under SDN networking, the access switch will also convert the VLAN data frame into a VxLAN data frame. Whether it is a switch, a router or an SDN controller, it can support such data frames well. Therefore, the existing switches and routers in the data center can support this solution without replacement, which makes up for the defects of functional mechanisms such as DHCP under traditional networking, and does not require modification of upper-layer services. At the same time, it actually realizes transparent transmission processing, and can achieve normal business communication;

[0081] Furthermore, since the vSwitch or SR-IOV network card of the virtual machine platform and its supporting agent program can be expanded to introduce more network plug-ins to achieve automatic configuration of switches, routers and other devices, the data frame transparent transmission solution is simpler and the configuration process is simpler, which can realize automatic network activation during the entire life cycle of the service.

[0094] The inventors noticed during the invention process that:

[0095] Existing transparent transmission processing technology solutions generally implement VLAN transparent transmission by encapsulating an additional VLAN layer on the outer layer of the service VLAN on the vSwitch and SR-IOV before the data frame is sent to the server to form a QinQ (802.1Q-in-802.1Q) data frame. Figure 3 This is a schematic diagram of VLAN transparent transmission. The specific solution is as follows Figure 3 shown.

[0096] When the data frame sent by the virtual port carries the "business VLAN" - Q1, the vSwitch or SR-IOV network card will encapsulate it with an additional layer of isolation VLAN - Q2 to become a QinQ data frame. The encapsulated Q2 is a fixed ID of the virtual network, and the inbound traffic is processed in the reverse direction.

[0097] To correctly transparently transmit QinQ data frames, you need to configure the QinQ data frame transparent transmission policy on the access switch (general switches support it). When QinQ data frames need to be routed (as shown in the figure, after being routed by the gateway, they are forwarded to the bearer network VLAN Q3), there are two options for traditional networking:

[0098] Option 1: Configure flexible QinQ policy on the uplink port of the access switch, strip the outer VLAN Q2 and send it to the gateway, then strip Q1 and forward it after entering the VPN corresponding to Q1, and process the inbound traffic in the reverse direction. Flexible QinQ policy is not supported by all switches.

[0099] Option 2: Configure QinQ termination policy on the downstream port of the gateway device. The original QinQ data packet directly enters the VPN corresponding to Q1+Q2, strips all VLANs, and then forwards them by table lookup. The inbound traffic is processed in the reverse direction. Currently, only high-end routers support QinQ termination policy, and switches do not support it.

[0100] In SDN networking, policies can be configured on access switches to convert QinQ data frames into VxLAN data frames, which are then routed and forwarded by the gateway, while inbound traffic is processed in the reverse direction.

[0101] This solution has at least one of the following disadvantages:

[0102] The overall solution is relatively complex, posing huge challenges to integrated configuration and subsequent operation and maintenance.

[0103] Access switches are required to support flexible QinQ policies, or gateway devices are required to support QinQ termination policies. When existing devices in the data center do not meet the requirements, additional funds need to be invested to purchase higher-end devices for replacement, and network upgrades and renovations will result in business interruption for a certain period of time.

[0104] The DHCP (Dynamic Host Configuration Protocol) service of the virtualization platform cannot support QinQ data frames. Unless SDN networking is adopted (SDN controllers generally support DHCP) or other alternative solutions (such as OpenStack Config Drive (OpenStack configuration drive, please refer to the technical definition of this field for the meaning of OpenStack, there is no corresponding Chinese)) are adopted, DHCP or its related functions (such as the virtual machine metadata service provided by the virtualization platform through DHCP) cannot be implemented. Alternative solutions often require certain upgrades and modifications to network elements.

[0105] Based on this, an embodiment of the present invention proposes a common technical solution for traditional networking and SDN networking to solve one of the above technical problems. Specific implementations of the present invention are described below in conjunction with the accompanying drawings.

[0106] In the description process, the implementation of sending data to a switch and sending data to a virtual port will be described respectively, and then an example of the coordinated implementation of the two will be given to better understand the implementation of the solution given in the embodiment of the present invention. This description does not mean that the two must be implemented in coordination or must be implemented separately. In fact, when sending data to a switch and sending data to a virtual port are implemented separately, they also solve the problem of sending data to a switch and sending data to a virtual port respectively, and when the two are used in combination, better technical effects will be obtained.

[0107] Figure 4 The data frame transmission method 1 is a flow chart of implementation, as shown in the figure, which may include:

[0108] Step 401: The virtual machine platform receives a data frame carrying VLAN information sent by the virtual machine from a virtual port;

[0109] Step 402: The virtual machine platform converts the VLAN information in the data frame into a corresponding VLAN header according to the configuration table, wherein the configuration table includes a correspondence between the VLAN information and the VLAN header;

[0110] Step 403: The virtual machine platform sends a data frame carrying a VLAN header to the switch.

[0111] Figure 5 The schematic diagram of the implementation flow of the second data frame transmission method is shown in the figure, which may include:

[0112] Step 501: The virtual machine platform receives a data frame carrying a VLAN header sent by a switch;

[0113] Step 502: The virtual machine platform converts the VLAN header in the data frame into corresponding VLAN information according to the configuration table, wherein the configuration table includes a correspondence between the VLAN information and the VLAN header;

[0114] Step 503: The virtual machine platform sends a data frame carrying VLAN information to the virtual port of the virtual machine.

[0115] In implementation, the data frame transmission is performed by vSwitch and / or SR-IOV.

[0116] When explaining with examples below, these two will be mainly used as examples.

[0117] Specifically, Figure 6 This is a schematic diagram of the configuration of a vSwitch or SR-IOV network card. UNTAG is untagged data, corresponding to the VLAN header Q2-1 of the isolation layer. Q1-1 of the service VLAN information corresponds to the VLAN header Q2-2 of the isolation layer. Similarly, Q1-n of a service VLAN information corresponds to the VLAN header Q2-n of an isolation layer.

[0118] As shown in the figure, when implementing transparent transmission of the "service VLAN", the vSwitch and SR-IOV network card can implement the vSwitch VLAN conversion by configuring a conversion table, that is, converting different service VLANs into different virtual network IDs.

[0119] In implementation, the configuration table is configured by the front-end API.

[0120] In a specific implementation, the configuration table is configured by calling the front-end API through the northbound interface of the virtualization platform.

[0121] In implementation, for data frames that do not carry VLAN information, it can be implemented as follows:

[0122] The virtual machine platform receives a data frame that does not carry VLAN information and is sent by the virtual machine from the virtual port;

[0123] The virtual machine platform encapsulates a VLAN header corresponding to the VLAN information for the data frame according to the configuration table, wherein the configuration table contains a correspondence between the VLAN information not carried and the VLAN header;

[0124] The virtual machine platform sends a data frame carrying a VLAN header to the switch.

[0125] as well as:

[0126] The virtual machine platform receives the data frame carrying the VLAN header sent by the switch;

[0127] After the virtual machine platform determines that the data frame does not carry VLAN information according to the configuration table, it strips the VLAN header of the data frame, wherein the configuration table contains the correspondence between the data frame not carrying VLAN information and the VLAN header;

[0128] The virtual machine platform sends a data frame with the VLAN header stripped off to a virtual port of the virtual machine corresponding to the VLAN information.

[0129] Figure 7 The network policy configuration process for a vSwitch or SR-IOV network card is shown in the figure, including:

[0130] 1. Configure network policies through the northbound interface of the virtualization platform;

[0131] 2. Call the network plug-in to send the network policy to the agent program of the relevant node;

[0132] 3. The agent is configured to the vSwitch or SR-IOV network card according to the policy.

[0133] The virtualization platform vSwitch Agent (virtual switch agent) or SR-IOV Agent (SR-IOV agent) program configures the vSwitch and SR-IOV network card according to the virtual network policy issued by the front-end API (Application Program Interface). The configured conversion table and conversion policy are the same as Figure 6 shown.

[0134] Through the above processing, the data frame from the virtual machine will only carry one layer of VLAN when forwarded to the access switch. Under SDN networking, the access switch will also convert the VLAN data frame into a VxLAN data frame. Whether it is a switch, router or SDN controller, it can support such data frames well. Figure 8 This is a schematic diagram of data frame conversion. The data frame conversion is shown in the figure.

[0135] Fig. 9 It is a virtual network schematic diagram. When a data frame corresponds to a virtual network, the virtualization platform configures a virtual DHCP server for each virtual network, as shown in the figure.

[0136] When receiving data packets sent by virtual machines, vSwitch and SR-IOV perform corresponding conversions based on the VLAN information carried, thereby connecting different types of data frames to different virtual networks (and their DHCP services):

[0137] When the data frame from the virtual machine does not carry VLAN, it is encapsulated as a data frame of net-1 (network 1) (ID is the ID of net1) data frame, and the service is identified by the ID of virtual network net1 to achieve tenant isolation. This is the default behavior of the virtualization platform.

[0138] When the data frame from the virtual machine carries VLAN Q2-N, it is converted into a data frame of netN (with the ID of netN), and the service is identified by the ID of the virtual network net-N, thus achieving tenant isolation. This is the effect achieved after the innovation of this proposal.

[0139] Based on the same inventive concept, a virtualization platform and a computer-readable storage medium are also provided in an embodiment of the present invention. Since the principles of solving the problems by these devices are similar to those of the data frame transmission method, the implementation of these devices can refer to the implementation of the method, and the repeated parts will not be repeated.
