Description

Technical Field

[0001] The present application relates to the field of cloud computing, and in particular to a cloud communication method, apparatus, computer equipment, computer-readable storage medium, and computer program product. Background Art

[0002] At present, Eip (Elastic IP Address) is usually bound to the cloud host to achieve communication between the cloud host and the external network. Specifically, when the cloud host binds Eip to access the external network, it is necessary to perform dynamic ARP (Address Resolution Protocol) matching on the IP address of the data packet to match the target MAC address, so as to achieve cloud host access to the external network.

[0003] However, the dynamic ARP matching process will send an ARP request to the external network switch. When the external network switch processes the ARP request, it needs to be processed by the CPU (Central Processing Unit) of the external network switch. It is easy for the external network switch to occupy a lot of CPU, causing the external network switch to be overloaded and unable to process successful ARP requests, resulting in the inability to realize the cloud host's access to the external network.

Their purpose is only to illustrate the feasibility of the implementation of the technical solution of this application, but it does not mean that the applicant has or will necessarily use the solution.

[0049] The cloud communication method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. The cloud communication system includes an Eip gateway network element, an external network switch and an SDN controller, which are deployed on the server 104. If the Eip gateway network element of the server 104 detects a cloud host data packet bound to the cloud host, the IP address in the cloud host data packet is extracted through the Eip gateway network element to obtain the data packet IP address; according to the data packet IP address, the routing information is queried in the routing IP address set of the Eip gateway network element to obtain the target IP address, wherein the routing IP address set is configured by the SDN controller for the Eip gateway network element; according to the target IP address, the address is queried in the static address set of the Eip gateway network element to obtain the target MAC address, wherein the static address set is configured by the SDN controller for the external network switch; the target MAC address is configured on the external network port of the external network switch through the SDN controller. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, etc. The head mounted device may be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. The server 104 may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0050] In an exemplary embodiment, Figure 2 As shown, a cloud communication method is provided, which is applied to Figure 1 The server 104 in the example is used as an example to illustrate, including the following steps 202 to 208. Among them:

[0051] Step 202: If the Eip gateway network element detects a cloud host data packet bound to the cloud host, the IP address in the cloud host data packet is extracted by the Eip gateway network element to obtain the data packet IP address.

[0052] Among them, in the cloud communication system of step 202, the Eip gateway network element communicates with the external network switch and the SDN controller respectively, and the cloud host accesses the external network switch, that is, the external network, through the Eip gateway network element.

[0053] Exemplarily, the IP address in the cloud host data packet is extracted through the Eip gateway network element to obtain the data packet IP address, including: extracting the message five-tuple information of the cloud host data packet through the Eip gateway network element to obtain message extraction information, and extracting the IP address in the message extraction information through the Eip gateway network element to obtain the data packet IP address.

[0054] The message extraction information includes at least one of SIP (Session Initialization Protocol) information, sport (source IP address), DIP (Destination Internet Protocol) information and dport (destination IP address).

[0055] Further, the IP address in the message extraction information is extracted by the Eip gateway network element to obtain the data packet IP address, including: determining the source IP address in the message extraction information as the data packet IP address by the Eip gateway network element.

[0056] Step 204: According to the IP address of the data packet, a routing information query is performed in the routing IP address set of the Eip gateway network element to obtain the target IP address, wherein the routing IP address set is configured by the SDN controller for the Eip gateway network element.

[0057] The routing IP address set consists of at least one IP address that is allowed to access the Eip gateway network element, and the routing IP address set can be a routing table.

[0058] Exemplarily, step 204 includes: querying a target IP address that matches the IP address of the data packet from a set of routing IP addresses of the EIP gateway network element.

[0059] As an embodiment, querying the target IP address matching the data packet IP address from the routing IP address set of the Eip gateway network element includes: querying the target IP address belonging to the same network segment as the data packet IP address from the routing IP address set of the Eip gateway network element.

[0060] It is understandable that there may be an Eip gateway network element that does not have an IP address that matches the IP address corresponding to the cloud host, that is, the IP address used by the cloud host does not have permission to access the Eip gateway network element. At this time, the routing IP address set of the Eip gateway network element does not contain a target IP address that matches the IP address of the data packet.

[0061] Optionally, as an embodiment, the method further includes: when the IP address of the data packet does not match the routing IP address set of the Eip gateway network element, sending address mismatch indication information to the cloud host through the Eip gateway network element.

[0062] In this way, the data packet IP address does not match the routing IP address set of the Eip gateway network element. The cloud host can receive the address mismatch indication information in time and then proceed to the next step. For example, the cloud host changes the data packet IP address of the cloud host data packet and then resends the cloud host data packet to the Eip gateway network element.

[0063] Step 206: According to the target IP address, an address query is performed in the static address set of the Eip gateway network element to obtain the target MAC address, wherein the static address set is obtained by configuring the SDN controller for the external network switch.

[0064] The static address set includes the correspondence between the configured IP address and the configured MAC address corresponding to the external network switch, and the static address set may be an ARP table.

[0065] Exemplarily, step 206 includes: querying from the static address set of the Eip gateway network element, the target configuration IP address whose corresponding configuration IP address matches the target IP address, and determining the configuration MAC address corresponding to the target configuration IP address in the static address set of the Eip gateway network element as the target MAC address.

[0066] Further, as an embodiment, querying from the static address set of the Eip gateway network element, the target configuration IP address whose corresponding configuration IP address matches the target IP address includes: obtaining the similarity between the target IP address and each configuration IP address in the static address set of the Eip gateway network element, and querying from the static address set of the Eip gateway network element, the target configuration IP address whose corresponding similarity is greater than a preset similarity threshold.

[0067] As another embodiment, the target configuration IP address corresponding to the configuration IP address that matches the target IP address is queried from the static address set of the Eip gateway network element, including: the target configuration IP address corresponding to the configuration IP address that belongs to the same network segment as the target IP address is queried from the static address set of the Eip gateway network element.

[0068] Step 208: configure the target MAC address on the external network port of the external network switch through the SDN controller.

[0069] Exemplarily, step 208 includes: generating target MAC address configuration data according to the target MAC address through the SDN controller, and configuring the target MAC address configuration data on the external network port of the external network switch through the SDN controller.

[0070] As an embodiment, the target MAC address configuration data is generated according to the target MAC address by the SDN controller, including: obtaining a preset configuration protocol through the SDN controller, and generating the target MAC address configuration data according to the preset configuration protocol and the target MAC address, wherein the preset configuration protocol can be a Netconf (Network Configuration Protocol) protocol.

[0071] As an embodiment, the target MAC address configuration data is configured at the external network port of the external network switch through the SDN controller, including: storing the target MAC address configuration data at the external network port of the external network switch through the SDN controller, or sending the target MAC address configuration data to the external network switch through the SDN controller, so that when the external network switch receives the target MAC address configuration data sent by the SDN controller, the target MAC address configuration data is stored in the external network port.

[0072] The above cloud communication method is applied to a cloud communication system, which includes an Eip gateway network element, an external network switch and an SDN controller; if the Eip gateway network element detects a cloud host data packet bound to a cloud host, the IP address in the cloud host data packet is extracted by the Eip gateway network element to obtain the data packet IP address; according to the data packet IP address, a routing information query is performed in the routing IP address set of the Eip gateway network element to obtain the target IP address, wherein the routing IP address set is configured by the SDN controller for the Eip gateway network element; according to the target IP address, an address query is performed in the static address set of the Eip gateway network element to obtain the target MAC address, wherein the static address set is configured by the SDN controller for the external network switch; by The SDN controller configures the target MAC address on the external network port of the external network switch. In this solution, the static address set and the routing IP address set are configured by the SDN controller for the external network switch. Therefore, there will be no situation where the packet IP address matches the routing IP address set corresponding to the Eip gateway network element, while the target IP address matched in the routing IP address set does not match the static address set. The static address set is a static matching process, so it will not trigger the process of sending an ARP request to the external network switch. Therefore, when the packet IP address matches the routing IP address set corresponding to the Eip gateway network element, the query of the target MAC address can be realized, that is, it is guaranteed that the cloud host can access the external network without affecting the normal operation of the external network switch.

[0073] In an exemplary embodiment, Figure 3 As shown, a method for accurately configuring the switch IP address, Eip routing IP address and switch MAC address is provided. According to the target IP address, the static address of the Eip gateway network element is centrally queried. Before obtaining the target MAC address, the method further includes steps 302 to 304. Among them:

[0074] Step 302: configure the switch IP address and switch MAC address for the external network switch through the SDN controller, and configure the Eip routing IP address for the Eip gateway network element through the SDN controller.

[0075] Exemplarily, step 302 includes: obtaining an external network switching segment corresponding to an external network switch through an SDN controller, obtaining an Eip switching segment corresponding to an Eip gateway network element through an SDN controller, and obtaining multiple idle segments through an SDN controller; selecting a first segment that does not overlap with the external network switching segment from multiple idle segments through an SDN controller, and selecting a second segment that does not overlap with the Eip switching segment from multiple idle segments through an SDN controller; selecting a switch IP address from the first segment through an SDN controller, and selecting an Eip routing IP address from the second segment through an SDN controller.

[0076] The number of first network segments may be single or multiple, and the number of second network segments may be single or multiple, which is not limited here.

[0077] It can be understood that both the external network switching segment and the Eip switching segment belong to the public switching segment. Further, as an embodiment, a first segment that does not overlap with the external network switching segment is selected from multiple idle segments, and a second segment that does not overlap with the Eip switching segment is selected from multiple idle segments, including: selecting a first segment and a second segment belonging to a private switching segment from multiple idle segments.

[0078] In this way, since the external network switching segment and the Eip switching segment usually belong to the public switching segment, by selecting the idle segment belonging to the private switching segment as the first segment and the second segment, it can be achieved that the first segment does not overlap with the external network switching segment, and the second segment does not overlap with the Eip switching segment, thereby improving the selection efficiency of the first segment and the second segment.

[0079] In this way, the SDN controller configures IP addresses in the idle network segments of the private switching network segments for the Eip gateway network element and the external network switch, reducing the traffic occupation of the external network switching network segment and the Eip switching network segment belonging to the public switching network segment, ensuring that public communication can proceed smoothly.

[0080] Further, as an embodiment, selecting a switch IP address from the first network segment and selecting an Eip routing IP address from the second network segment includes: randomly selecting a switch IP address from the first network segment and randomly selecting an Eip routing IP address from the second network segment.

[0081] It is understandable that when the switch IP address is randomly selected from the first network segment and the Eip routing IP address is randomly selected from the second network segment, the first network segment may overlap with the second network segment or may not overlap.

[0082] Taking into account the possibility of overlap between the first network segment and the second network segment, in order to avoid repeated configuration of IP addresses, as an embodiment, a switch IP address is selected from the first network segment, and an Eip routing IP address is selected from the second network segment, including: randomly selecting a switch IP address from the first network segment, and selecting an Eip routing IP address that is different from the switch IP address from the second network segment.

[0083] As another embodiment, selecting a switch IP address from the first network segment and selecting an Eip routing IP address from the second network segment includes: randomly selecting an Eip routing IP address from the second network segment and selecting a switch IP address different from the Eip routing IP address from the first network segment.

[0084] Step 304: Send the switch IP address, switch MAC address and Eip routing IP address to the Eip gateway network element through the SDN controller, and send the switch IP address and switch MAC address to the external network switch through the SDN controller.

[0085] In this way, it is ensured that the Eip gateway network element can configure the Eip routing IP address configured by the SDN controller, and that the external network switch can configure the switch IP address and switch MAC address configured by the SDN controller, thereby ensuring that when the subsequent cloud host uses the communication data packet adapted to the Eip routing IP address and the switch IP address, the cloud host can access the external network switch, that is, the cloud host can access the external network.

[0086] Optionally, as an embodiment, after the switch IP address, switch MAC address and Eip routing IP address are sent to the Eip gateway network element through the SDN controller, the method also includes: configuring the static address table entry corresponding to the external network switch through the Eip gateway network element according to the received switch IP address and switch MAC address; updating the static address set corresponding to the Eip gateway network element through the Eip gateway network element according to the static address table entry, and updating the routing IP address set corresponding to the Eip gateway network element through the Eip gateway network element according to the received Eip routing IP address.

[0087] As an embodiment, the Eip gateway network element configures the static address table entry corresponding to the external network switch according to the received switch IP address and switch MAC address, including: the Eip gateway network element matches the received switch IP address and switch MAC address to obtain the static address table entry corresponding to the external network switch.

[0088] Optionally, as an embodiment, after the switch IP address and the switch MAC address of the external network switch are configured and sent to the external network switch through the SDN controller, the method also includes: obtaining a preset configuration protocol through the SDN controller; and configuring the switch IP address and the switch MAC address on the loopback port of the external network switch according to the preset configuration protocol through the SDN controller.

[0089] The preset configuration protocol may be the Netconf protocol.

[0090] Further, the switch IP address and the switch MAC address are configured at the loopback port of the external network switch according to a preset configuration protocol through the SDN controller, including: generating switch IP address configuration data through the SDN controller according to the preset configuration protocol and the switch IP address, and generating switch MAC address configuration data through the SDN controller according to the preset configuration protocol and the switch MAC address; configuring the switch IP address configuration data and the switch MAC address configuration data at the loopback port of the external network switch through the SDN controller.

[0091] As an embodiment, configuring the switch IP address configuration data and the switch MAC address configuration data on the loopback port of the external network switch through the SDN controller includes: storing the switch IP address configuration data and the switch MAC address configuration data on the loopback port of the external network switch through the SDN controller, or sending the switch IP address configuration data and the switch MAC address configuration data to the external network switch through the SDN controller, so that when the external network switch receives the switch IP address configuration data and the switch MAC address configuration data sent by the SDN controller, the switch IP address configuration data and the switch MAC address configuration data are stored in the loopback port.

[0092] In this embodiment, the SDN controller configures the switch IP address and the switch MAC address for the external network switch, and the SDN controller configures the Eip routing IP address for the Eip gateway network element; the SDN controller sends the switch IP address, the switch MAC address and the Eip routing IP address to the Eip gateway network element, and the SDN controller sends the switch IP address and the switch MAC address to the external network switch, thereby realizing accurate address allocation of the SDN controller to the external network switch and the Eip gateway network element, so that the cloud host can access the external network during subsequent communication.

[0093] As a detailed embodiment, if the Eip gateway network element detects a cloud host data packet bound to the cloud host, the IP address in the cloud host data packet is extracted through the Eip gateway network element to obtain the data packet IP address; the external network switching segment corresponding to the external network switch is obtained through the SDN controller, the Eip switching segment corresponding to the Eip gateway network element is obtained, and multiple idle network segments are obtained; the first network segment that does not overlap with the external network switching segment is selected from the multiple idle network segments through the SDN controller, and the second network segment that does not overlap with the Eip switching segment is selected from the multiple idle network segments; the switch IP address is randomly selected from the first network segment through the SDN controller, and the Eip routing IP address is randomly selected from the second network segment; the switch IP address, the switch MAC address and the Eip routing IP address are sent to the Eip gateway network element through the SDN controller, and the switch IP address and the switch MAC address are sent to the external network switch through the SDN controller.

[0094] Further, the Eip gateway network element configures the static address table item corresponding to the external network switch according to the received switch IP address and switch MAC address; the Eip gateway network element updates the static address set corresponding to the Eip gateway network element according to the static address table item, and the Eip gateway network element updates the routing IP address set corresponding to the Eip gateway network element according to the received Eip routing IP address; the SDN controller obtains the preset configuration protocol; the SDN controller configures the switch IP address and the switch MAC address on the loopback port of the external network switch according to the preset configuration protocol; when the IP address of the data packet does not match the routing IP address set of the Eip gateway network element In the case of a match, an address mismatch indication message is sent to the cloud host through the Eip gateway network element; in the case that the IP address of the data packet matches the routing IP address set of the Eip gateway network element, a routing information query is performed in the routing IP address set of the Eip gateway network element according to the IP address of the data packet to obtain the target IP address, wherein the routing IP address set is configured by the SDN controller for the Eip gateway network element; according to the target IP address, an address query is performed in the static address set of the Eip gateway network element to obtain the target MAC address, wherein the static address set is configured by the SDN controller for the external network switch; the target MAC address is configured on the external network port of the external network switch through the SDN controller.

[0095] In this way, in this solution, both the static address set and the routing IP address set are configured by the SDN controller for the external network switch. Therefore, there will be no situation where the data packet IP address matches the routing IP address set corresponding to the Eip gateway network element, while the target IP address matched in the routing IP address set does not match the static address set. The static address set is a static matching process, so it will not trigger the process of sending an ARP request to the external network switch. Therefore, when the data packet IP address matches the routing IP address set corresponding to the Eip gateway network element, the query of the target MAC address can be realized, that is, it is guaranteed that the cloud host can access the external network without affecting the normal operation of the external network switch.

[0096] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders.
