[0001] The present application relates to the field of network communication technology, and in particular to a multicast traffic forwarding method, device and computer equipment. Background Art

[0002] With the popularization of cloud computing technology, the multicast service architecture of traditional switching and routing networks faces significant challenges in cloud environments. Traditional multicast transmission relies on layer 2 and 3 devices to achieve data distribution, but it is difficult to meet the dynamic business needs of the cloud era in terms of multi-tenant elastic expansion, link resource utilization, and network convergence speed.

[0003] Especially when some hosts in the Internet Data Center (IDC) under the cloud are migrated to the cloud, multicast services need to support both intra-cloud forwarding and extra-cloud detours, forming complex hybrid multicast scenarios, including multicast sources outside the cloud / inside the cloud, receivers distributed inside and outside the cloud or across virtual private clouds (VPCs), and other situations.

[0004] In the scenario where the multicast source is outside the cloud and the receiver exists both inside and outside the cloud, it is urgent to realize the intelligent on-demand distribution of multicast traffic inside and outside the cloud without reconstructing the existing network.

[0092] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0093] Before introducing the multicast traffic forwarding method provided by this application, it should be noted that the multicast service transmission of the traditional switching routing network needs to rely on multicast layer 2 and 3 devices, and with the advent of the cloud era, this transmission method has increasingly exposed some shortcomings. First, the number of multi-tenants and elasticity requirements have increased dramatically, and the traditional network cannot meet the requirements in terms of link utilization and convergence speed; secondly, the deployment of multicast services requires the deployment of related equipment that supports multicast functions, and the investment cost is relatively high. At present, after some hosts of IDC are migrated to the cloud (that is, deployed in the cloud environment), the original multicast service must not only be forwarded in the cloud, but also bypass the cloud to ensure the original service. Based on this situation, the visible multicast scenarios are: the multicast source (that is, the traffic generation end) is outside the cloud, and the multicast receiver (that is, the traffic receiving end) is both inside and outside the cloud; the multicast source is outside the cloud, and the multicast receiver is only in the cloud; the multicast source is in the cloud, and the multicast receiver is only outside the cloud; the multicast source is in the cloud, and the multicast receiver is in the cloud VPC; the multicast source is in the cloud, and the multicast receiver is between the cloud VPCs, etc. For the scenario where the multicast source is outside the cloud and the multicast receivers are both inside and outside the cloud, it is a problem to be solved to achieve on-demand multicast forwarding by leveraging the advantages within the cloud without changing the networking.

[0094] The current solution to this problem is to connect the IDC outside the cloud to the VPC on the cloud through a dedicated line, configure the multicast domain range, the multicast source outside the cloud, and the virtual machine inside the cloud as the multicast receiver. The multicast gateway inside the cloud forwards the multicast source to the offline IDC and the multicast receiver receives the multicast traffic in the cloud. When the multicast receiver is outside the cloud, it is still implemented through the switching and routing network outside the cloud.

[0095] However, the above method has the following problems: (1) It requires the router device to support functions such as Internet Group Management Protocol (IGMP) and Protocol Independent Multicast (PIM). When the device model is old or the version is low, the multicast distribution function cannot be realized, and the physical device requirements are high; (2) When the IDCs corresponding to the multicast source and multicast receiver are partially on the cloud, the intra-cloud and extra-cloud forwarding traffic must not only be received on the cloud but also forwarded to the cloud via the physical network, which increases the network maintenance cost. To this end, this application provides a new multicast traffic forwarding method to solve the above problems.

[0096] The multicast traffic forwarding method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown in the figure, first of all, the English abbreviations in the figure are explained: Virtual Gateway (VGW), Virtual Machine (VM), Layer 2 Gateway (L2GW). IDC has been introduced in the previous content and will not be repeated here.

[0097] The traffic generation end may be deployed in IDC1, the traffic receiving end may be deployed in IDC2, and VM1 may also be understood as the traffic receiving end. The multicast controller 102 and the first forwarding gateway 104 (i.e. Figure 1 L2GW1 in the figure) and the first forwarding gateway 106 (i.e. Figure 1 L2GW2 in the communication connection between each other; IDC1 is connected to L2GW1 through VGW1; IDC2 is connected to L2GW2 through VGW2; L2GW1 is connected to VM1. Normally, the traffic generation end, that is, the multicast source will be deployed in IDC1, and the traffic receiving end, that is, the multicast receiver will be deployed in IDC2. For the convenience of explanation, in this embodiment, IDC1 can be directly understood as the traffic generation end, and IDC2 can be understood as the traffic receiving end. Among them, VGW1 can be understood as the second forwarding gateway corresponding to the traffic generation end; VGW2 can be understood as the second forwarding gateway corresponding to the traffic receiving end.

[0098] It is worth noting that understanding IDC1 as a traffic generating end and IDC2 as a traffic receiving end is only an example provided in the embodiment of the present application, and is not a limitation on the traffic generating end and the traffic receiving end. In some scenarios, IDC1 can also be understood as a traffic receiving end and IDC2 can be understood as a traffic generating end.

[0099] Specifically, L2GW1, L2GW2 and multicast controller 102 are respectively deployed in the cloud environment; traffic generation end IDC1 is deployed in the cloud environment. Multicast controller 102 receives traffic source data corresponding to the traffic to be forwarded, and traffic destination data corresponding to the traffic to be forwarded; the traffic source data is sent by L2GW1; the traffic destination data is sent by L2GW2; the multicast controller 102 generates a traffic forwarding path corresponding to the traffic to be forwarded according to the traffic source data and the traffic destination data; the multicast controller 102 performs forwarding control on the traffic to be forwarded based on the traffic forwarding path.

[0100] In an exemplary embodiment, Figure 2 As shown, a multicast traffic forwarding method is provided, which is applied to Figure 1 The multicast controller in the example is used to illustrate the process, including the following steps:

[0101] S210, receiving traffic source data corresponding to the traffic to be forwarded, and traffic destination data corresponding to the traffic to be forwarded.

[0102] Among them, the traffic to be forwarded is the traffic that needs to be multicast forwarded. It can be understood that due to the differences in traffic requirements of different traffic receiving ends, the corresponding traffic to be forwarded may be different. The traffic source data is used to characterize the traffic source of the traffic to be forwarded. Usually, the traffic source data is used to indicate the entities involved in the path from the traffic generation end to the first forwarding gateway corresponding to the traffic generation end. The traffic destination data is used to characterize the traffic destination of the traffic to be forwarded. Usually, the traffic destination data is used to indicate the entities involved in the path from the first forwarding gateway corresponding to the traffic receiving end to the traffic receiving end.

[0103] For example, Figure 1 Taking the application environment diagram shown as an example, traffic source data may include IDC1, VGW1, and L2GW1, and traffic destination data may include L2GW2, VGW2, and IDC2.

[0104] Among them, the traffic source data is sent by the first forwarding gateway (i.e. L2GW1) corresponding to the traffic generation end; the traffic destination data is sent by the first forwarding gateway (i.e. L2GW2) corresponding to the traffic receiving end; the first forwarding gateway (i.e. L2GW1) corresponding to the traffic generation end, the first forwarding gateway (i.e. L2GW2) corresponding to the traffic receiving end and the multicast controller are respectively deployed in the cloud environment; the traffic generation end (i.e. IDC1) is deployed in the cloud environment.

[0105] In an optional implementation, when the traffic receiving end is deployed in a cloud environment, the first forwarding gateway corresponding to the traffic generating end is the same as the first forwarding gateway corresponding to the traffic receiving end. Figure 1Taking the application environment diagram shown as an example, the traffic receiving end VM1 is deployed in the cloud environment, the first forwarding gateway corresponding to the traffic generating end IDC1 is L2GW1, and the first forwarding gateway corresponding to the traffic receiving end VM1 is also L2GW1.

[0106] In another alternative implementation, when the traffic receiving end is deployed in an external cloud environment, the first forwarding gateway corresponding to the traffic generating end is communicatively connected to the first forwarding gateway corresponding to the traffic receiving end. Exemplarily, taking Figure 1 the application environment diagram shown as an example, the traffic receiving end IDC2 is deployed in the external cloud environment, the first forwarding gateway corresponding to the traffic generating end IDC1 is L2GW1, the first forwarding gateway corresponding to the traffic receiving end IDC2 is L2GW2, and L2GW1 and L2GW2 are communicatively connected.

[0107] Exemplarily, an extensible virtual local area network (Virtual eXtensible LAN, VXLAN) tunnel is formed between L2GW1 and L2GW2 for communication. It should be noted that for the same multicast group, the VXLAN network identifiers (VXLAN Network Identifier, VNI) of the tunnels formed between its respective L2GWs are the same.

[0108] S220, generate a traffic forwarding path corresponding to the traffic to be forwarded according to the traffic source data and the traffic destination data.

[0109] Exemplarily, in this embodiment, the traffic source data and the traffic destination data can be connected according to the traffic transmission direction to generate a traffic forwarding path corresponding to the traffic to be forwarded.

[0110] Taking Figure 1 the application environment diagram shown as an example, according to the traffic source data (IDC1, VGW1, and L2GW1) and the traffic destination data (L2GW2, VGW2, and IDC2) and the traffic transmission direction, IDC1->VGW1->L2GW1->L2GW2->VGW2->IDC2 can be generated as the traffic forwarding path corresponding to the traffic to be forwarded.

[0111] S230, perform forwarding control on the traffic to be forwarded based on the traffic forwarding path.

[0112] Exemplarily, according to the traffic source data, control the first forwarding gateway corresponding to the traffic generating end to obtain the traffic to be forwarded from the traffic generating end and send the traffic to be forwarded to the first forwarding gateway corresponding to the traffic receiving end; according to the traffic destination data, control the first forwarding gateway corresponding to the traffic receiving end to send the traffic to be forwarded to the traffic receiving end.

[0113] Specifically, taking Figure 1Taking the application environment diagram shown as an example, the multicast controller controls L2GW1 to obtain the traffic to be forwarded from IDC1 through VGW1, and controls L2GW1 to transmit the traffic to be forwarded to L2GW2; and controls L2GW2 to transmit the traffic to be forwarded to IDC2 through VGW2.

[0114] In the above multicast traffic forwarding method, by deploying the first forwarding gateway corresponding to the traffic generating end and the first forwarding gateway corresponding to the traffic receiving end between the traffic generating end and the traffic receiving end, the traffic to be forwarded can be transmitted between the two first forwarding gateways, thereby forwarding the traffic to be forwarded from the traffic generating end to the traffic receiving end. Specifically, when the traffic generating end is deployed in an off-cloud environment, the multicast controller generates a traffic forwarding path corresponding to the traffic to be forwarded by receiving the traffic source data sent by the first forwarding gateway corresponding to the traffic generating end and the traffic destination data sent by the first forwarding gateway corresponding to the traffic receiving end, and forwards the traffic to be forwarded based on the traffic forwarding path. This process opens up the transmission channel for forwarding the traffic to be forwarded from the traffic generating end to the traffic receiving end when the traffic generating end is in an off-cloud environment and the traffic receiving end is in an off-cloud environment or in an on-cloud environment, and solves the problem of high network maintenance cost for on-cloud and off-cloud forwarding traffic that needs to be received on the cloud and forwarded via the physical network when part of the IDC of the traffic generating end and the traffic receiving end is on the cloud, while saving the cost of physical equipment.

[0115] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment. In this optional embodiment, the traffic source data includes the first identification information of the traffic generating end and the second identification information of the first forwarding gateway corresponding to the traffic generating end; the traffic destination data includes the third identification information of the traffic receiving end and the fourth identification information of the first forwarding gateway corresponding to the traffic receiving end. In this case, the specific process of generating the traffic forwarding path corresponding to the traffic to be forwarded based on the traffic source data and the traffic destination data is given.

[0116] See also Figure 3 The steps of generating a traffic forwarding path include:

[0117] S310: Generate a traffic output path according to the first identification information and the second identification information.

[0118] The first identification information is used to indicate basic information of the traffic generation end, for example, the first identification information may include IDC1. The second identification information is used to indicate basic information of the first forwarding gateway corresponding to the traffic generation end, for example, the second identification information may include L2GW1. The traffic output path is used to indicate the path of the traffic to be forwarded from the traffic generation end to the first forwarding gateway corresponding to the traffic generation end.

[0119] For example, IDC1->L2GW1 can be used as the traffic output path. In this embodiment, since IDC1 is usually unable to directly transmit traffic to L2GW1, Figure 1 Taking the application environment diagram shown as an example, the traffic output path can be IDC1->VGW1->L2GW1.

[0120] S320: Generate a traffic receiving path according to the third identification information and the fourth identification information.

[0121] The third identification information is used to indicate basic information of the traffic receiving end, for example, the third identification information may include IDC2. The fourth identification information is used to indicate basic information of the first forwarding gateway corresponding to the traffic receiving end, for example, the fourth identification information may include L2GW2. The traffic receiving path is used to indicate the path of the traffic to be forwarded from the first forwarding gateway corresponding to the traffic receiving end to the traffic receiving end.

[0122] For example, when the traffic receiving end is deployed in an off-cloud environment, L2GW2->IDC2 can be used as the traffic receiving path. In this embodiment, since IDC2 is usually unable to directly transmit traffic to L2GW2, Figure 1 Taking the application environment diagram shown as an example, the traffic receiving path can be L2GW2->VGW2->IDC2.

[0123] Exemplarily, when the traffic receiving end is deployed in a cloud environment, L2GW1->VM1 can be used as a traffic receiving path.

[0124] S330, connecting the traffic output path and the traffic receiving path in order to obtain a traffic forwarding path corresponding to the traffic to be forwarded.

[0125] Exemplarily, taking the traffic output path as IDC1->VGW1->L2GW1 and the traffic receiving path as L2GW2->VGW2->IDC2 as an example, the traffic output path and the traffic receiving path are connected, and the resulting traffic forwarding path can be IDC1->VGW1->L2GW1->L2GW2->VGW2->IDC2.

[0126] Exemplarily, when IDC1 is a traffic generating end and VM1 is a traffic receiving end, the corresponding traffic output path may be IDC1->VGW1->L2GW1, and the traffic receiving path may be L2GW1->VM1.

[0127] In the above embodiment, a specific process for generating a traffic forwarding path corresponding to the traffic to be forwarded is given. Specifically, the first identification information of the traffic generating end, the second identification information of the first forwarding gateway corresponding to the traffic generating end, the third identification information of the traffic receiving end and the fourth identification information of the first forwarding gateway corresponding to the traffic receiving end are used as the basis for generating the traffic forwarding path, so that the generated traffic forwarding path is clearer.

[0128] In an exemplary embodiment, Figure 4 As shown, a multicast traffic forwarding method is provided, which is applied to Figure 1 Taking L2GW1 (that is, the first forwarding gateway corresponding to the traffic generation end) in FIG. 1 as an example, the following steps are included:

[0129] S410, receiving traffic to be forwarded from a traffic generating end, and determining traffic source data corresponding to the traffic to be forwarded.

[0130] by Figure 1 Taking the application environment diagram shown as an example, L2GW1 may receive the traffic to be forwarded sent by IDC1 through VGW1, and determine the traffic source data corresponding to the traffic to be forwarded.

[0131] Exemplarily, L2GW1 receives a traffic service message sent by VGW1. Since the traffic service message is a message encapsulated by two layers of VXLAN, L2GW1 can decapsulate the two layers of VXLAN and identify the traffic service message. When it is determined that the traffic service message includes traffic to be forwarded, L2GW1 uses the decapsulated information as traffic source data and sends the traffic source data to the multicast controller.

[0132] The two-layer VXLAN encapsulation of the traffic service message is as follows: the inner encapsulation includes the identification information of L2GW1; the outer encapsulation includes the identification information of IDC1 and the identification information of its corresponding VPC. It is worth noting that L2GW corresponds to VPC one-to-one, and L2GW connection corresponds to subnet in VPC one-to-one. Accordingly, the identification information of L2GW1 can also include the identification information of its corresponding VPC. Similarly, the identification information of L2GW2 can also include the identification information of its corresponding VPC.

[0133] Optionally, the traffic service message sent by VGW1 to L2GW1 is processed. Exemplarily, the processing process can be as follows: VGW1 receives the initial service message encapsulated by two layers of VXLAN sent by IDC1, and unpacks the outer VXLAN; VGW1 determines the identification information of the VPC corresponding to L2GW1 based on the information of the inner VXLAN, and re-encapsulates the initial service message according to the identification information of the VPC to obtain the traffic service message.

[0134] The two-layer VXLAN encapsulation of the initial service message is as follows: the inner encapsulation includes the identification information of L2GW1; and the outer encapsulation includes the identification information of IDC1 and the identification information of VGW1.

[0135] S420, sending the traffic source data to the multicast controller, so that the multicast controller can generate a traffic forwarding path corresponding to the traffic to be forwarded based on the traffic source data and the traffic destination data determined by the first forwarding gateway corresponding to the traffic receiving end, and perform forwarding control on the traffic to be forwarded based on the traffic forwarding path.

[0136] Among them, the first forwarding gateway corresponding to the traffic generating end, the first forwarding gateway corresponding to the traffic receiving end and the multicast controller are respectively deployed in the cloud environment; the traffic generating end is deployed in the cloud environment.

[0137] In the above multicast traffic forwarding method, by deploying the first forwarding gateway corresponding to the traffic generating end and the first forwarding gateway corresponding to the traffic receiving end between the traffic generating end and the traffic receiving end, the traffic to be forwarded can be transmitted between the two first forwarding gateways, thereby forwarding the traffic to be forwarded from the traffic generating end to the traffic receiving end. Specifically, when the traffic generating end is deployed in an off-cloud environment, the multicast controller generates a traffic forwarding path corresponding to the traffic to be forwarded by receiving the traffic source data sent by the first forwarding gateway corresponding to the traffic generating end and the traffic destination data sent by the first forwarding gateway corresponding to the traffic receiving end, and forwards the traffic to be forwarded based on the traffic forwarding path. This process opens up the transmission channel for forwarding the traffic to be forwarded from the traffic generating end to the traffic receiving end when the traffic generating end is in an off-cloud environment and the traffic receiving end is in an off-cloud environment or in an on-cloud environment, and solves the problem of high network maintenance cost for on-cloud and off-cloud forwarding traffic that needs to be received on the cloud and forwarded via the physical network when part of the IDC of the traffic generating end and the traffic receiving end is on the cloud, while saving the cost of physical equipment.

[0138] In an exemplary embodiment, Figure 5 As shown, a multicast traffic forwarding method is provided, which is applied to Figure 1 Taking L2GW2 (that is, the first forwarding gateway corresponding to the traffic receiving end) in FIG. 1 as an example, the following steps are included:

[0139] S510: Receive a multicast on-demand request from a traffic receiving end.

[0140] The multicast on-demand request is used to request the sending of traffic to be forwarded.

[0141] by Figure 1 Taking the application environment diagram shown as an example, L2GW2 may receive a multicast on-demand request sent by IDC2 through VGW2.

[0142] Exemplarily, L2GW2 receives the multicast on-demand request sent by VGW2. Since the multicast on-demand request is a two-layer VXLAN encapsulated message, L2GW2 can decapsulate the two-layer VXLAN and identify the multicast on-demand request. When it is determined that the multicast on-demand request is used to request multicast traffic forwarding, the decapsulated information is used as traffic destination data and the traffic destination data is sent to the multicast controller.

[0143] The two-layer VXLAN encapsulation of the multicast on-demand request is as follows: the inner encapsulation includes the identification information of L2GW2; and the outer encapsulation includes the identification information of IDC2 and the identification information of its corresponding VPC.

[0144] Optionally, the multicast on-demand request sent by VGW2 to L2GW2 is processed. Exemplarily, the processing process can be as follows: VGW2 receives the initial request message encapsulated by two layers of VXLAN sent by IDC2, and unpacks the outer VXLAN; VGW2 determines the identification information of the VPC corresponding to L2GW2 based on the information of the inner VXLAN, and re-encapsulates the initial request message according to the identification information of the VPC to obtain the multicast on-demand request.

[0145] The two-layer VXLAN encapsulation of the initial request message is as follows: the inner encapsulation includes the identification information of L2GW2; and the outer encapsulation includes the identification information of IDC2 and the identification information of VGW2.

[0146] S520, determining traffic destination data corresponding to the traffic to be forwarded.

[0147] Specifically, in this embodiment, the information obtained after decapsulating the multicast on-demand request can be used as the traffic destination data.

[0148] S530, sending the traffic destination data to the multicast controller, so that the multicast controller can generate a traffic forwarding path corresponding to the traffic to be forwarded based on the traffic destination data and the traffic source data determined by the first forwarding gateway corresponding to the traffic generating end, and perform forwarding control on the traffic to be forwarded based on the traffic forwarding path.

[0149] Among them, the first forwarding gateway corresponding to the traffic generating end, the first forwarding gateway corresponding to the traffic receiving end and the multicast controller are respectively deployed in the cloud environment; the traffic generating end is deployed in the cloud environment.

[0150] In the above multicast traffic forwarding method, by deploying the first forwarding gateway corresponding to the traffic generating end and the first forwarding gateway corresponding to the traffic receiving end between the traffic generating end and the traffic receiving end, the traffic to be forwarded can be transmitted between the two first forwarding gateways, thereby forwarding the traffic to be forwarded from the traffic generating end to the traffic receiving end. Specifically, when the traffic generating end is deployed in an off-cloud environment, the multicast controller generates a traffic forwarding path corresponding to the traffic to be forwarded by receiving the traffic source data sent by the first forwarding gateway corresponding to the traffic generating end and the traffic destination data sent by the first forwarding gateway corresponding to the traffic receiving end, and forwards the traffic to be forwarded based on the traffic forwarding path. This process opens up the transmission channel for forwarding the traffic to be forwarded from the traffic generating end to the traffic receiving end when the traffic generating end is in an off-cloud environment and the traffic receiving end is in an off-cloud environment or in an on-cloud environment, and solves the problem of high network maintenance cost for on-cloud and off-cloud forwarding traffic that needs to be received on the cloud and forwarded via the physical network when part of the IDC of the traffic generating end and the traffic receiving end is on the cloud, while saving the cost of physical equipment.

[0151] It should be noted that, taking L2GW2 as an example, if L2GW2 receives the first addition of a user multicast group or the last user of a user multicast group leaves, it can report an IGMP Report or IGMP Leave message to the multicast controller, and the multicast group on-demand request / leave path is IDC2->VGW2->L2GW2->multicast controller->L2GW1. If L2GW1 receives an IGMP request message from VM1 in the cloud, the multicast group on-demand request / leave path is VM1->L2GW1->multicast controller. Furthermore, if the multicast controller receives an IGMP Report or IGMP Leave message from L2GW1, the multicast controller can maintain the L2GW1->L2GW2 multicast distribution information table.

[0152] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment. In this optional embodiment, the multicast traffic forwarding method provided by the present application is applied to Figure 1 Taking the application environment shown in the figure as an example, the method is described in detail.

[0153] See also Figure 6 The multicast traffic forwarding method shown includes:

[0154] S601, L2GW2 receives a multicast on-demand request from a traffic receiving end; the multicast on-demand request is used to request sending of traffic to be forwarded;

[0155] For example, when VGW2 receives the Overlay IGMPReport initial request message of two-layer VXLAN encapsulation sent by IDC2 through the dedicated line, it decapsulates the outer dedicated line VXLAN, and identifies the MAC address of the VXLAN tunnel endpoint (VXLAN Tunnel EndPoint, VTEP) of L2GW2 according to the media access control address (Media Access Control Address, MAC) of the inner VXLAN message tunnel, and then identifies the initial request message as relay traffic, searches for the L2GW2 connection to re-encapsulate the outer VXLAN, obtains the multicast on-demand request, and sends the multicast on-demand request to L2GW2;

[0156] S602, L2GW2 determines traffic destination data corresponding to the traffic to be forwarded;

[0157] The traffic destination data includes the third identification information of the traffic receiving end and the fourth identification information of L2GW2;

[0158] Exemplarily, L2GW2 decapsulates the two-layer VXLAN encapsulation of the multicast on-demand request, identifies the Overlay IGMP Report message, and further identifies it as proxy traffic, configures the three-layer logical port L2GWLOOPm (m is the logical port number), and maintains the L2GW2 connection multicast VXLAN table, that is, establishes the connection record between L2GW2 and L2GW1;

[0159] S603, L2GW2 sends the traffic destination data to the multicast controller;

[0161] The traffic source data includes the first identification information of the traffic generating end and the second identification information of L2GW1;

[0162] For example, VGW1 receives the overlay initial service message of two-layer VXLAN encapsulation sent by IDC1 outside the cloud through a dedicated line, decapsulates the outer dedicated line VXLAN, and identifies the MAC address of the VTEP of L2GW1 according to the dmac of the inner VXLAN message tunnel, and further identifies it as relay traffic, searches for L2GW1 to connect and re-encapsulate the outer VXLAN, obtains the traffic service message, and sends the traffic service message to L2GW1; further, L2GW1 decapsulates the two-layer VXLAN, identifies it as an overlay traffic service message, and refreshes the L2GW1 connection multicast VXLAN table, that is, establishes the connection record between L2GW1 and L2GW2;

[0163] S605, L2GW1 sends the traffic source data to the multicast controller;

[0164] Among them, L2GW1, L2GW2 and multicast controller are deployed in the cloud environment respectively; the traffic generation end is deployed in the cloud environment; when the traffic receiving end is deployed in the cloud environment, L2GW1 is the same as L2GW2; when the traffic receiving end is deployed in the cloud environment, L2GW1 is connected to L2GW2 for communication;

[0165] S606, the multicast controller generates a traffic output path according to the first identification information and the second identification information;

[0166] S607, the multicast controller generates a traffic receiving path according to the third identification information and the fourth identification information;

[0167] S608, the multicast controller connects the traffic output path and the traffic receiving path in the order of the traffic output path and the traffic receiving path to obtain a traffic forwarding path corresponding to the traffic to be forwarded;

[0168] S609, the multicast controller sends the traffic output path to L2GW1;

[0169] S610, the multicast controller sends the traffic receiving path to L2GW2;

[0170] S611, the multicast controller controls L2GW1 to obtain the traffic to be forwarded from the traffic generation end according to the traffic output path, and sends the traffic to be forwarded to L2GW2;

[0171] Among them, L2GW1 configures the Layer 3 logical interface Internet Protocol (IP) address and creates a transparent transmission tunnel from L2GW1 to L2GW2;

[0172] S612: The multicast controller controls L2GW2 to send the traffic to be forwarded to the traffic receiving end according to the traffic receiving path.
