Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the disclosed aspects may be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known structures, methods, devices, implementations, materials, or operations are not shown or described in detail to avoid obscuring aspects of the disclosure.
The block diagrams depicted in the figures are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, or in one or more software-hardened modules, or in different networks and/or processor devices and/or microcontroller devices.
With the development of the internet, terminal devices accessing the network are increasing. In the current public cloud scenario, an overlay network architecture is generally constructed by adopting a VXLAN tunnel encapsulation technology, and access and service capabilities of an indoor physical machine to a public network can be completed through forwarding gateways such as an EIP (Elastic IP Address, elastic public network) gateway, an LB (LoadBalance) gateway, an NAT (Network Address Translation ) gateway and the like.
Specifically, the EIP gateway supports the static conversion function of the elastic public network IP and the cloud physical machine intranet IP, namely the intranet IP of the cloud physical machine and the elastic public network IP are mapped one by one, and in the Internet, the user can log in the cloud physical machine through the bound EIP; the NAT gateway supports sub-network level binding, realizes the function of actively accessing the Internet by a cloud physical machine in a VPC (Virtual Private Cloud ) through public network IP address conversion, but does not support the function of actively accessing the cloud physical machine in the VPC by the Internet, and the cloud physical machine cannot be actively accessed to the cloud physical machine through the Internet because the cloud physical machine and the public network IP are not mapped one by one; the balanced loader/flow distributor uniformly distributes public network IP routes in the data center, supports VXLAN tunnel encapsulation and decapsulation, realizes the distribution of different service flows, and performs functions such as flow charging and speed limiting on the public network IP.
In the related art, the north-south forwarding of the service traffic can be realized through a service traffic forwarding gateway (bmgw), and when the service traffic passes through the service traffic forwarding gateway, the forwarding gateway can be determined according to a routing policy corresponding to the service traffic. For example, when the subnet where the cloud physical machine is located binds the NAT gateway, all Internet traffic is forwarded to the NAT gateway through bmgw; when the cloud physical machine binds the elastic public network IP, because the EIP routing has higher priority than the NAT routing, the traffic actively accessing the Internet by the cloud physical machine is forwarded to the EIP gateway through the traffic forwarding gateway, and in addition, other cloud physical machines which are not bound with the elastic public network IP in the sub-network are forwarded through the NAT gateway.
In the service flow forwarding scheme in the related technology, when the cloud physical machine binds the elastic public network, forwarding can only be performed through the EIP gateway. However, in certain scenarios, the user has certain needs. For example, NAT gateways are required when the user's requirements are ultra-large bandwidth, large public network IP usage, high availability, and security. The existing flow forwarding scheme cannot adjust the forwarding gateway according to the service, so that the service processing efficiency is poor, the resource consumption is high, and the use experience of a user is poor.
According to the data message forwarding method provided in the present exemplary embodiment, when a data message is obtained and a direction of the data message is determined, when the data message is an inbound data message, the inbound data message is forwarded to a target terminal device according to routing information corresponding to the inbound data message, when the data message is an outbound data message, a plurality of forwarding gateways corresponding to the inbound data message and forwarding priorities corresponding to the plurality of forwarding gateways are obtained, a target forwarding gateway of the inbound data message is determined according to the forwarding priorities, and the outbound data message is forwarded through the target forwarding gateway. As shown in fig. 1, the data packet forwarding method may include the following steps:
step S110, obtaining a data message and judging the direction of the data message;
step S120, when the data message is an incoming data message, forwarding the incoming data message to the target terminal device according to the routing information corresponding to the incoming data message;
step S130, when the data message is the outgoing data message, a plurality of forwarding gateways corresponding to the outgoing data message and forwarding priorities corresponding to the forwarding gateways are obtained, and a target forwarding gateway of the outgoing data message is determined according to the forwarding priorities;
And step S140, forwarding the outgoing data message through the target forwarding gateway.
In the data message forwarding method provided in this example embodiment, the target forwarding gateway may be determined according to the priority of the forwarding gateway. On one hand, the priorities corresponding to different forwarding gateways can be adjusted in real time, and the forwarding gateways are adjusted according to the demands of users in time, so that the service demands of different users are met, and the application scenes of the forwarding gateways are further enriched; on the other hand, the forwarding gateway adapting to the current scene can be selected according to the current service scene, so that the service can be flexibly and efficiently operated, the service processing efficiency is improved, the resource consumption is reduced, and the use experience of a user is further enhanced.
Next, steps S110 to S140 of the data packet forwarding method in the present exemplary embodiment will be described in more detail with reference to the drawings and the embodiments.
Step S110, obtaining a data message and judging the direction of the data message;
in one example embodiment of the present disclosure, a data message during a network transmission may be obtained. Specifically, the data packet may include data units exchanged and transmitted in the network, that is, data blocks to be sent by the station at one time. The message contains the complete data information to be sent, and the length of the message can be inconsistent, and the length is unlimited and variable. Further, during network transmission, the data packets are continuously encapsulated into packets, and frames for transmission, wherein some information segments, such as header, are added, and are organized in a certain format. The package includes various information, such as message type, message version, message length, message entity, etc. Messages may be used to exchange information between systems for requests and responses, and may be required to comply with a prescribed format.
In one example embodiment of the present disclosure, after the data message is acquired, the direction of the data message may be determined. Specifically, when the data message is sent by a client/terminal device and the like and received by a server, the data message is an outgoing data message; the data message is sent by the server and received by the client/terminal equipment, etc., and is an incoming data message. The direction of the data message can be determined by the format of the data message, and the direction of the data message can also be determined by the specific content of the data message. It should be noted that, the determination method of the direction of the data packet in the present disclosure is not limited in particular.
In an example embodiment of the present disclosure, data message format information corresponding to a data message may be acquired, and when header information is not included in the data message format information, the data message is discarded. Referring to fig. 2, when header information is not included in the datagram format information, the datagram is discarded, and the following steps S210 to S220 may be included:
step S210, obtaining data message format information corresponding to the data message;
in one example embodiment of the present disclosure, after the data message is acquired, data message format information of the data message may be acquired. Specifically, the data message format information is the format of the data message, and the type of the data message can be determined according to the data message format information. For example, the VXLAN data message may include information such as an original message, VXLAN Header, outer IP Header, outer MAC Header, UDP Header, etc. It should be noted that, the present disclosure does not limit the format information of the data message corresponding to the data message in particular.
Step S220, discarding the data message when the header information is not included in the data message format information.
In an example embodiment of the present disclosure, after the data message format information is obtained in the above steps, it may be determined whether header information is included in the data message format information, and when the header information is not included in the data message format information, the data message is discarded. Specifically, the header information may include a node address corresponding to the data packet, and when the format information of the data packet does not include the header information, the node address corresponding to the data packet cannot be obtained, and further the data packet cannot be forwarded. For example, for a VXLAN data packet, the IP address of the VTEP may be encapsulated in an Outer IP Header, the source IP address in the VXLAN packet is the VTEP address of the node, the destination IP address in the VXLAN packet is the VTEP address of the peer node, a pair of VTEP addresses corresponds to one VXLAN tunnel, and for a data packet without the VXLAN tunnel, discarding processing may be directly performed.
Through the steps S210 to S220, the data message format information corresponding to the data message can be obtained, and when the data message format information does not include header information, the data message is discarded.
In an example embodiment of the present disclosure, a data message routing type corresponding to a data message may be obtained, and the data message is determined to be an outbound data message or an inbound data message according to the data message routing type. Referring to fig. 3, determining whether a data packet is an outbound data packet or an inbound data packet according to a data packet routing type may include the following steps S310 to S320:
step S310, obtaining the routing type of the data message corresponding to the data message;
in an example embodiment of the present disclosure, a data message routing type corresponding to a data message may be obtained. Specifically, the data message routing type may be used to indicate the classification of the transaction to be performed after the data message is successfully matched with the routing table. A routing table is a spreadsheet (file) or class database stored in a router or networked computer. The routing table stores paths that point to specific network addresses. Further, the routing table contains topology information of the periphery of the network. The main objective of the routing table set-up is to implement routing protocols and static routing. The routing information of the data message corresponding to the data message can be determined through the routing table. For example, for VXLAN data packets, the routing types may include a network type, a NAT type, and an EIP type.
Step S320, determining the data message as an outbound data message or an inbound data message according to the data message routing type.
In an example embodiment of the present disclosure, after the data message routing type corresponding to the data message is obtained through the above steps, the data message may be determined to be an outbound data message or an inbound data message according to the data message routing type. Specifically, the data message routing type may be used to indicate a transaction to be performed after the data message is successfully matched with the routing table, that is, the direction of the data message may be determined by the data message routing type. If the data message routing type is sent by the client/terminal equipment and received by the server, the data message is an outgoing data message; if the data message routing type is sent by the server and received by the client/terminal equipment, the data message is an incoming data message. For example, for VXLAN data messages, the network type is an inbound data message, and the NAT type and the EIP type are outbound data messages.
Through the steps S310 to S320, the data message routing type corresponding to the data message can be obtained, and the data message is determined to be an outgoing data message or an incoming data message according to the data message routing type.
In an example embodiment of the present disclosure, data packets may be parsed to obtain IP address data and subnet data corresponding to the data packets, and a data packet routing type corresponding to the data packets may be determined according to the IP address data and the subnet data. Referring to fig. 4, determining a data packet routing type corresponding to a data packet according to IP address data and subnet data may include the following steps S410 to S420:
step S410, analyzing the data message to obtain IP address data and subnet data corresponding to the data message;
in an example embodiment of the present disclosure, after obtaining the data packet, the data packet may be parsed to obtain IP address data and subnet data corresponding to the data packet. Specifically, in the network transmission process, the data message needs to be encapsulated so as to be transmitted. For example, for VXLAN messages, the original message may be encapsulated according to VXLAN header, UDP header, outer IP header, outer ethernet header. After receiving the data message, the data message needs to be parsed to obtain IP address data and subnet data corresponding to the data message, wherein the IP address data can be used for indicating an intranet IP address of the terminal equipment/client, and the subnet data can be used for indicating a subnet where the terminal equipment/client is located. For example, for a VXLAN message, the IP address data is an IP header in the original message, which represents an intranet IP address of an intra-cloud physical machine, and the subnet data is a VNI in the VXLAN header. It should be noted that, the parsing method of the data message is not particularly limited in this disclosure.
Step S420, determining the routing type of the data message corresponding to the data message according to the IP address data and the subnet data.
In an example embodiment of the present disclosure, after the IP address data and the subnet data corresponding to the data packet are obtained through the above steps, the routing type of the data packet corresponding to the data packet may be determined according to the IP address data and the subnet data. In particular, the IP address data may be the same in different subnets, so that a terminal device/client can be uniquely determined in combination with the IP address data and the subnet data. The IP address data and subnet data may be compared with entries in the routing table, and after determining the terminal device/client, the routing type of the data message corresponding to the data message may be obtained according to the routing table.
Through the steps S410 to S420, the data message may be parsed to obtain the IP address data and the subnet data corresponding to the data message, and the routing type of the data message corresponding to the data message may be determined according to the IP address data and the subnet data.
Step S120, when the data message is an incoming data message, forwarding the incoming data message to the target terminal device according to the routing information corresponding to the incoming data message;
In an example embodiment of the present disclosure, after determining the direction of the data packet through the above steps, it may be obtained whether the data packet is an inbound data packet or an outbound data packet. When the data message is an incoming data message, the incoming data message can be forwarded to the target terminal device according to the routing information corresponding to the incoming data message, wherein the terminal device can comprise an intra-cloud physical machine. Specifically, when the data message is sent by the server and received by the client/terminal device, the data message is an incoming data message. When the data message enters the client/terminal equipment, the data message does not need to pass through a forwarding gateway, and only the data message needs to be forwarded to the corresponding node.
Therefore, the routing information corresponding to the incoming data message can be obtained, the routing information can include routing type, encapsulation information and the like, the routing type can be used for indicating a transaction to be performed after the data message is successfully matched with the routing table, and when the data message is the incoming data message, the data message can be directly forwarded to the target terminal device, or the data message can be filled and then sent to the target terminal device. The specific content of the routing information is not particularly limited in this disclosure.
For example, for the VXLAN message, the IP information on the outer layer, VNI information, and destination MAC information on the inner layer of the VXLAN message may be modified and filled and then forwarded to a tor (Top of Rack, a wiring mode of a data center) of the intra-cloud physical machine, which means forwarding the data message to an upstream switch where the intra-cloud physical machine is located, or directly forwarding the data message to the intra-cloud physical machine.
Step S130, when the data message is the outgoing data message, a plurality of forwarding gateways corresponding to the outgoing data message and forwarding priorities corresponding to the forwarding gateways are obtained, and a target forwarding gateway of the outgoing data message is determined according to the forwarding priorities;
in an example embodiment of the present disclosure, after determining the direction of the data packet through the above steps, it may be obtained whether the data packet is an inbound data packet or an outbound data packet. When the data message is an outbound data message, the outbound data message is required to be forwarded to the server through the forwarding gateway, and a plurality of forwarding gateways corresponding to the outbound data message and forwarding priorities corresponding to the forwarding gateways can be obtained. Specifically, when the data message is sent by the client/terminal device and the like and received by the server, the data message is the outgoing data message. When forwarding the outgoing data message, the outgoing data message can be forwarded through different forwarding gateways. For example, for public cloud service scenarios, when the data packet is an outbound data packet, forwarding may be performed through an EIP gateway or a NAT gateway. At this time, priorities of the plurality of forwarding gateways may be obtained, and a target forwarding gateway may be determined according to the priorities of the forwarding gateways, where the target forwarding gateway may be used to forward the outbound data packet. Further, the forwarding gateway with higher priority may be determined as the target forwarding gateway, or the forwarding gateway with lower priority may be determined as the target forwarding gateway.
In an example embodiment of the present disclosure, a plurality of forwarding gateways corresponding to outbound data packets and configuration data corresponding to the outbound data packets may be obtained, and forwarding priorities corresponding to the plurality of forwarding gateways may be determined according to the configuration data corresponding to the outbound data packets. Referring to fig. 5, determining forwarding priorities corresponding to a plurality of forwarding gateways according to configuration data corresponding to outgoing data packets may include the following steps S510 to S520:
step S510, obtaining a plurality of forwarding gateways corresponding to the outgoing data message and configuration data corresponding to the outgoing data message;
in an example embodiment of the present disclosure, a plurality of forwarding gateways corresponding to outgoing data packets and configuration data corresponding to outgoing data packets may be obtained. Specifically, when forwarding the outbound data message, forwarding can be performed through different forwarding gateways, so that all forwarding gateways and configuration data corresponding to the outbound data message can be obtained. Specifically, after the outbound data message is obtained, the outbound data message may be parsed, and configuration data corresponding to the outbound data message may be obtained. Wherein the configuration data may be used to indicate priorities of the plurality of forwarding gateways.
Step S520, determining the forwarding priority corresponding to the forwarding gateways according to the configuration data corresponding to the outgoing data message.
In an example embodiment of the present disclosure, after the configuration data corresponding to the outbound data packet is obtained, forwarding priorities corresponding to the plurality of forwarding gateways may be determined according to the configuration data corresponding to the outbound data packet. For example, the configuration data may be a priority sequence table, and the priority corresponding to the forwarding gateway may be searched in the table. It should be noted that, the specific content of the configuration data is not particularly limited in this disclosure.
Through the steps S510 to S520, a plurality of forwarding gateways corresponding to the outbound data packet and configuration data corresponding to the outbound data packet can be obtained, and forwarding priorities corresponding to the plurality of forwarding gateways can be determined according to the configuration data corresponding to the outbound data packet.
In an example embodiment of the present disclosure, a forwarding preset condition may be obtained, and when the IP address data and the subnet data satisfy the forwarding preset condition, forwarding priorities corresponding to a plurality of forwarding gateways are determined according to the outbound port data. Referring to fig. 6, determining forwarding priorities corresponding to a plurality of forwarding gateways according to output port data may include the following steps S610 to S620:
Step S610, obtaining forwarding preset conditions; the forwarding preset conditions comprise IP address standard data and subnet standard data;
in an example embodiment of the present disclosure, the configuration data may include IP address data, subnet data, and outbound port data, where the IP address data and subnet data may uniquely identify a terminal device/client, and the outbound port data may be used to represent port information through which the data packet passes. For example, for public cloud scenarios, the IP address data is a three-layer source IP address including an inner layer protocol, the subnet data is a subnet identification, and the outgoing port data is a four-layer destination port of the inner layer protocol. The forwarding preset condition may include a condition that needs to be satisfied when forwarding is performed. The forwarding preset conditions comprise IP address standard data and subnet standard data.
Step S620, when the IP address data and the subnet data meet the preset forwarding conditions, forwarding priorities corresponding to a plurality of forwarding gateways are determined according to the outbound port data.
In an example embodiment of the present disclosure, after the IP address data and the subnet data are acquired through the above steps, it may be determined whether the IP address data and the subnet data satisfy the forwarding preset condition. Specifically, when the IP address data and the subnet data are the same as the IP address standard data and the subnet data are the same as the subnet standard data, a terminal device/client can be uniquely determined when the IP address data and the subnet data satisfy the forwarding preset condition. At this time, forwarding priorities corresponding to the plurality of forwarding gateways may be determined according to the outbound port data in the configuration data. Specifically, a port section corresponding to the port data can be obtained, each forwarding gateway corresponds to a certain section in the port section, and if the port data falls into a certain section, the priority of the forwarding gateway corresponding to the section is set to be higher. The present disclosure is not limited to a specific manner of determining the priority of the plurality of forwarding gateways according to the output port data.
Through the steps S610 to S620, the forwarding preset conditions may be obtained, and when the IP address data and the subnet data meet the forwarding preset conditions, the forwarding priorities corresponding to the forwarding gateways are determined according to the outbound port data.
In one example embodiment of the present disclosure, when the outbound port data matches the first priority port data, a priority of a first forwarding gateway corresponding to the first priority port data is determined as a first priority, and a priority of one or more second forwarding gateways other than the first forwarding gateway among the plurality of forwarding gateways is determined as a second priority. Referring to fig. 7, determining the priority of the first forwarding gateway corresponding to the first priority port data as the first priority and determining the priority of one or more second forwarding gateways other than the first forwarding gateway among the plurality of forwarding gateways as the second priority may include steps S710 to S720:
step S710, when the output port data is matched with the first priority port data, determining the priority of the first forwarding gateway corresponding to the first priority port data as a first priority;
in an example embodiment of the present disclosure, the forwarding preset condition further includes first priority port data, and when the outbound port data in the configuration data matches the first priority port data, the priority of the first forwarding gateway corresponding to the first priority port data may be determined as the first priority. The first priority port data may include a continuous section, a single section, a plurality of separation sections, and the like. For example, the destination port characteristic interval is [1,65535], and in this case, the continuous interval [1,1024] may be set as the first priority port data, the individual interval [1] may be set as the first priority port data, and the plurality of separation intervals [2,22] [3,33] [4,44] may be set as the first priority port data. Since the first priority port data is preset, the priorities of the plurality of forwarding gateways can be determined by setting the first priority port data.
For example, the forwarding gateway includes an EIP gateway and a NAT gateway, and the first priority port data corresponding to the EIP gateway may be set to be [1,65535] (65535 at maximum), where the priority of the EIP gateway is higher than that of the NAT gateway, that is, all outgoing data packets will be forwarded through the EIP, and the EIP gateway may be determined as the target forwarding gateway.
In step S720, priorities of one or more second forwarding gateways other than the first forwarding gateway among the plurality of forwarding gateways are determined as second priorities.
In one example embodiment of the present disclosure, after determining the priority of the first forwarding gateway, the priorities of the remaining forwarding gateways may be set to the second priority. For example, the forwarding gateway includes an EIP gateway and a NAT gateway, where the first priority port data corresponding to the EIP gateway may be set to [1024,65535] (65535 max), the port data corresponding to the NAT gateway is set to [1,1023], and when the priority of the EIP gateway is determined to be the first priority, the priority of the NAT gateway is determined to be the second priority.
At this time, if the outbound port data (i.e., the four-layer destination port of the inner layer protocol) is located between [1024,65535], it indicates that the current outbound data packet is an outbound response data packet matching the EIP gateway. Specifically, the outgoing response data message matched with the EIP gateway is not a data message for actively accessing the Internet by the terminal device/client, and the data message must be forwarded through the EIP gateway, so that a certain port interval needs to be reserved to ensure normal forwarding of the outgoing response data message, i.e. the EIP gateway can be determined as a target forwarding gateway at this time; if the outbound port data is located between [1,1023], then the priority of the EIP gateway is smaller than that of the NAT gateway, and the NAT gateway may be determined to be the target forwarding gateway.
Through the steps S710 to S720, when the outbound port data matches the first priority port data, the priority of the first forwarding gateway corresponding to the first priority port data is determined as the first priority, and the priority of one or more second forwarding gateways other than the first forwarding gateway among the plurality of forwarding gateways is determined as the second priority.
In an example embodiment of the present disclosure, a matching interval of the first priority port data may be obtained, and when the outbound port data corresponding to the outbound data packet is located in the matching interval, the outbound port data corresponding to the outbound data packet is matched with the port data. Referring to fig. 8, when the outbound port data corresponding to the outbound data packet is located in the matching section, the outbound port data corresponding to the outbound data packet is matched with the port data, and the following steps S810 to S820 may be included:
step S810, obtaining a matching section of the first priority port data;
step S820, when the outbound port data corresponding to the outbound data packet is located in the matching section, the outbound port data corresponding to the outbound data packet is matched with the port data.
In an example embodiment of the present disclosure, the first priority port data may include a matching section, when the first priority port data is matched with the outgoing port data, the matching section of the first priority port data may be obtained, and when the outgoing port data corresponding to the outgoing data packet is located in the matching section, the outgoing port data corresponding to the outgoing data packet is matched with the port data. For example, the matching interval of the first priority port data is [1024,65535], the outgoing port data corresponding to the outgoing data packet is 35534, at this time 35534 is at [1024,65535], the outgoing port data is matched with the port data, and if the outgoing port data corresponding to the outgoing data packet is a certain value in [1,1023], the outgoing port data is not matched with the port data.
Through the steps S810 to S820, a matching section of the first priority port data may be obtained, and when the outbound port data corresponding to the outbound data packet is located in the matching section, the outbound port data corresponding to the outbound data packet is matched with the port data.
And step S140, forwarding the outgoing data message through the target forwarding gateway.
In an example embodiment of the present disclosure, the scheme of the present disclosure may be performed by a programmable switch, and matching of forwarding preset conditions may be implemented by an MAU table (Match action unit), that is, performing actions corresponding to a key after matching the key is successful. Specifically, the MAU table includes a subnet identifier, an inner layer protocol three-layer source IP address, and an inner layer protocol four-layer destination port, where the subnet identifier and the inner layer protocol three-layer source IP address need to be matched accurately, the inner layer protocol four-layer destination port may be interval matched, and after the subnet identifier, the inner layer protocol three-layer source IP address, and the inner layer protocol four-layer destination port are all matched successfully, a corresponding action may be executed, for example, at this time, a gateway corresponding to the inner layer protocol four-layer destination port is an EIP gateway, and then the target forwarding gateway is determined as the target forwarding gateway. Further, the programmable switch may modify the MAU table to accommodate current traffic demands.
In an example embodiment of the present disclosure, for data packets of TCP and UDP, priorities of the EIP gateway and NAT gateway may be determined by matching inner layer protocol four layer destination port feature intervals; and for the data message of the ICMP, whether the data message is an outbound data message or an inbound data message can be determined through the first byte in the ICMP header (type), when the first byte of the type is 0, the data message is indicated to be the inbound data message, when the first byte of the type is 8, the data message is indicated to be the outbound data message, when the data message is determined to be the outbound data message, if the priority of the NAT gateway is greater than the priority of the EIP gateway, the outbound data message is forwarded through the NAT gateway, and if the priority of the NAT gateway is less than the priority of the EIP gateway, the outbound data message is forwarded through the EIP gateway.
In one example embodiment of the present disclosure, the priority of the NAT gateway and the EIP gateway may be set according to traffic situation. For example, in the case of a service requiring an ultra-large bandwidth, a large amount of public network IP usage, high availability, and security, the data packets passing through these ports may be forwarded through the NAT gateway; in the service situation that external service is needed to be provided, and the operation and maintenance personnel can conveniently conduct remote operation, the EIP gateway is more suitable for the requirement of a user port, and therefore the EIP gateway can be used for forwarding the user port.
In an example embodiment of the present disclosure, referring to fig. 9, an outbound data packet is sent by an intra-cloud physical machine, and sent to a virtual private network, the virtual private network forwards the outbound data packet to a traffic forwarding gateway, determines a priority of a NAT gateway or an EIP gateway in the traffic forwarding gateway (bmgw), determines a target forwarding network according to the priority of the NAT gateway or the EIP gateway, and then sends the outbound data packet passing through the NAT gateway or the EIP gateway to a traffic distributor, and finally, the traffic distributor sends the outbound data packet to the Internet.
In an example embodiment of the present disclosure, after a data packet is acquired, it may be first determined whether the data packet has a VXLAN tunnel, the data packet without the VXLAN tunnel is discarded, then it is determined whether the data packet satisfies a preset forwarding condition, if the forwarding condition is satisfied, the priority of the EIP gateway is greater than that of the NAT gateway at the time, that is, the routing information of the EIP gateway may be acquired, the direction of the data packet may be determined according to the routing table, when the data packet is an inbound data packet, the neighbor routing information may be acquired, the data packet is forwarded to a tor of an intra-cloud physical machine, when the data packet is an outbound data packet, the data packet may be predetermined to be forwarded to the NAT gateway (default gateway), then it is determined whether the data packet satisfies the preset forwarding condition, if the forwarding condition is satisfied, the priority of the EIP gateway is greater than that of the NAT gateway at the time, and the EIP gateway is determined as a target forwarding gateway, if the forwarding condition is not satisfied, the priority of the EIP gateway is determined as the target NAT gateway. Referring to fig. 10, the steps of acquiring a data packet and determining a target forwarding gateway may include the following steps S1001 to S1023:
Step S1001, obtaining a data message; step S1003, whether the data message has a VXLAN tunnel; step S1005, discarding the data message; step S1007, analyzing the data message and obtaining IP address data and subnet data; step S1009, matching the routing table according to the IP address data and the subnet data; step S1011, determining the direction of the data message according to the route type; step S1013, when the data message is an incoming data message, obtaining neighbor routing information; step S1015, the data message is forwarded to a tor of the physical machine in the cloud; step S1017, when the data message is an outbound data message, the data message is predetermined to be forwarded to the NAT gateway; step S1019, judging whether the data message meets the preset forwarding condition; step S1021, if the forwarding preset condition is met, acquiring the routing information of the EIP; step S1023, the EIP gateway is determined as a target forwarding gateway; step S1025, if the forwarding preset condition is not satisfied, determining the NAT gateway as the target forwarding gateway.
In an example embodiment of the present disclosure, when a data packet is acquired and a direction of the data packet is determined, when the data packet is an inbound data packet, forwarding the inbound data packet to a target terminal device according to routing information corresponding to the inbound data packet, and when the data packet is an outbound data packet, acquiring a plurality of forwarding gateways corresponding to the inbound data packet and forwarding priorities corresponding to the plurality of forwarding gateways, determining a target forwarding gateway of the inbound data packet according to the forwarding priorities, and forwarding the outbound data packet through the target forwarding gateway.
On one hand, the priorities corresponding to different forwarding gateways can be adjusted in real time, and the forwarding gateways are adjusted according to the demands of users in time, so that the service demands of different users are met, and the application scenes of the forwarding gateways are further enriched; on the other hand, the forwarding gateway adapting to the current scene can be selected according to the current service scene, so that the service can be flexibly and efficiently operated, the service processing efficiency is improved, the resource consumption is reduced, and the use experience of a user is further enhanced.
