With the rapid development of the internet and the continuous increase of the business volume of users, the requirements on the reliability and the performance of the business are higher and higher. In order to meet the requirements of users, an ha (high availability) cluster is often used in an actual application environment to implement service processing. In a high-availability cluster, cooperation and consistency among nodes are needed to ensure the effectiveness of the cluster on service processing. If a certain node in the cluster has a problem, the working performance of the whole cluster is affected, so that the cluster is required to have a function of rapidly processing the problem node, and the reliability of the cluster and the effectiveness of service processing are ensured.
In order to ensure high availability of the cluster, when the virtual server or the server accesses the external network, two or more uplink and downlink data packet forwarding links are usually arranged between the virtual server or the server and the external network, and switches are respectively arranged in the data packet forwarding links to control one data packet forwarding link individually. The method and the device realize that the downlink port of the data message is automatically closed when the uplink port fails through a routing protocol, and transfer the forwarding flow of the data message to other data message forwarding links so as to ensure the availability of the server.
However, when a physical port of a downlink is opened, a traffic of the downlink enters an uplink formed between an uplink port and an external network, and the uplink has an objective factor (e.g., external network congestion, traffic limitation, etc.) with uncertainty due to stability of the external network, so that a packet loss phenomenon occurs in a data packet forwarded to the external network in the uplink, thereby causing a defect of long failover time and poor user experience in a high-availability cluster.

The functions may be configured to perform operations using, for example, software running on a computer device, hardware (e.g., chip-implemented logic functions), and/or the like, and/or any combination thereof.
The first embodiment is as follows:
an embodiment of a method for controlling forwarding of data packets (hereinafter referred to as "method") according to the present invention is disclosed with reference to fig. 1 to 3. The method is used for executing unidirectional and/or bidirectional data message forwarding operation. The data message may result from the computing device 100 performing a user-initiated request generation in response to a user's request, such that the data message establishes a data link in the north-south direction in fig. 3, and the data link includes an uplink data link (i.e., uplink) between the plurality of connection switches and the external network 30, and a downlink data link (i.e., downlink) between the plurality of connection switches and the one or more service devices.
The data message forwarding control method comprises the following steps of S1 and S2.
Step S1 detects the stability of the first physical interface in the uplink in the three-layer network 31, and opens the downlink formed between the second physical interface and the processing device 40 when the uplink is in a stable state.
In order to improve the reliability of the data packet forwarding process and the high availability of the server or cluster server applying the method, in the scenario shown in this embodiment, a processing device (i.e. a generic concept of the server or cluster server) is configured with a physical network card NIC-1 and a physical network card NIC-2, and the number of the physical network cards is consistent with the number of switches (e.g. the switch 10 and the switch 20). The number of switches disposed between the three-layer network 31 and the two-layer network 32 is not limited to two, and may be three or more (for example, the switches 10, 20 to the switch N shown in fig. 3). The two-tier network (L2)32 is the data link layer and the three-tier network (L3)31 is the network layer. In the two-layer network 32, data packets can only be exchanged between one subnet, and if data is to be transmitted across subnets, path planning needs to be implemented by the path planning function of the three-layer network 31, that is, by the switch 10 and the switch 20.
As shown in fig. 2, in this embodiment, the switch 10 configures PORT-1 and PORT-2, the switch 20 configures PORT-3 and PORT-4, both PORT-1 and PORT-3 are first physical interfaces, both PORT-2 and PORT-4 are second physical interfaces, the PORT-2 of the switch 10 is connected to the physical network card NIC-1 and establishes a downlink, and the PORT-4 of the switch 20 is connected to the physical network card NIC-2 and establishes another downlink. PORT-1 establishes one uplink with the external network 30, and PORT-3 establishes another uplink with the external network 30. The first physical interface and the second physical interface are arranged in pair, and belong to at least two switches or only belong to the same switch (for example, the switch 10 or the switch 20, and a plurality of first physical interfaces and a plurality of second physical interfaces are configured in one switch), so that link switching is performed on at least two data packet forwarding channels through the first physical interface and the second physical interface, so as to implement High Availability (HA) and failover. The second physical interfaces of all switches are connected to processing equipment 40 located in the two-tier network 32. The task of the processing device 40 is to accept the user's request service, which may be based on various operations of the cloud platform, such as: migration operation request, write request, read request, etc. when the requested service is executed by the processing device 40, the generated data message passes through the uplink and downlink constructed by the switch 10 or the switch 20, the data message is unicast or broadcast between the processing device 40 and the external network 30, and finally the external network 30 responds to the service request initiated by the user through the designated network interface and protocol. The forwarding path rule of the switch 10 or the switch 20 is set to be important because the forwarding path of the switch is not selected by one switch, but is an optimal next hop address selected by a plurality of switches together. Therefore, the applicant indicates that in the forwarding method disclosed in this embodiment, two or more data forwarding channels may be implemented on the basis of one switch (i.e. port-level link switching referred to in this application), or implemented together with multiple switches such as the switch 10 and the switch 20 (i.e. device-level link switching referred to in this application), so as to achieve a convergence rate on the millisecond level, and thus, the networking environment with a strict real-time requirement can be satisfied.
Specifically, in the present embodiment, at least two uplinks (i.e., arrow 5 and arrow 6 constitute one uplink, arrow 7 and arrow 8 constitute the other uplink) and two downlinks (i.e., arrow 1 and arrow 2 constitute one downlink, arrow 3 and arrow 4 constitute the other downlink) are established between the processing device 40 and the external network 30 through at least two switches, detecting whether a first physical interface of the switch accessing an uplink is in a stable state, to match out the downlink capable of forwarding the data packet to the processing device 40, to establish at least two data packet forwarding channels between the external network 30 and the processing device 40 through the first physical interface and the second physical interface (refer to the data packet forwarding channel 80 and the data packet forwarding channel 81 shown in fig. 3), and the number of data packet forwarding paths is determined by the number of switches configured in the computing device 100. Referring to fig. 3, if the computing apparatus 100 includes N switches, 2 × N or more data packet forwarding channels may be formed, as long as one of the data packet forwarding channels is ensured to establish a complete uplink and downlink between the external network 30 and the processing device 40; wherein, a data message forwarding channel is composed of an uplink and a downlink formed by a switch. With reference to fig. 2, the applicant indicates that the first physical interfaces PORT-1 and PORT-3 and the second physical interfaces PORT-2 and PORT-4 configured by the switch 10 and the switch 20 can also be deployed in the same switch to implement the link switching at the PORT level, and the number of the first physical interfaces accessing the three-layer network 31 and the number of the second physical interfaces accessing the two-layer network 32 of the switch 10 and the switch 20 can be further configured to be greater than two, and the configured numbers of the first physical interfaces and the second physical interfaces do not need to be configured to be equal.
More specifically, in this embodiment, it is detected whether the first physical interface (PORT-1 or PORT-3) is stable in the three-layer network 31, and only when the first physical interface is in a stable state, the second physical interface located in the same switch and accessing the two-layer network 32 is opened. For example, if PORT-1 of switch 10 is detected to be stable, PORT-2 of switch 10 is turned on; if PORT-1 is detected to be unstable, PORT-2 of the switch 10 is not opened, and at this time, if PORT-3 of the switch 20 is detected to be stable, PORT-4 of the switch 20 is opened, thereby establishing a complete uplink and downlink through PORT-3 and PORT-4. In the present invention, if it is detected that the PORT-1 is unstable, the technical means of refusing to open the PORT-2 can effectively avoid the packet loss phenomenon caused by the instability of the three-layer network 31 in the uplink of the processing device 40, thereby ensuring the response effect and response efficiency to the access request initiated by the user. In general, in a cluster server or data, in order to improve network security, a plurality of switches are configured, so if an uplink constituted by arrow 5 and arrow 6 is in an unstable state, a downlink constituted by arrow 1 and arrow 2 is established, and a data packet forwarding channel is established between PORT-2 and physical network card NIC-1.
In this embodiment, detecting whether the first physical interface of the switch accessing the uplink is in a stable state specifically uses one or more of the following routing protocols: firstly, a static routing protocol is adopted to execute stability detection on a first physical interface; then, a dynamic routing protocol is employed to perform stability detection on the first physical interface. When the first physical interface (such as PORT-1 or PORT-3) is detected by using the static routing protocol and the dynamic routing protocol, and then the first physical interface is determined to be in a stable state, the second physical interface (such as PORT-2 or PORT-4) is opened. In an actual scenario, at least two data packet forwarding channels are established between the external network 30 and the processing device 40, so that when one of the data packet forwarding channels fails, the data packet can be forwarded in the other data packet forwarding channel.
The method for performing stability detection on the first physical interface by using the static routing protocol specifically comprises the following steps:
and detecting the stability of all configured uplinks based on the first physical interface by adopting a BFD protocol or an ICMP protocol. When the ICMP protocol is adopted for stability detection, an ICMP Request is used for detecting whether the next hop is reachable. When the BFD protocol is used, the echo function of the BFD protocol is used, the sending end and the opposite end address of the IP head of the echo message are set as the IP address of the interface where the echo message occurs, and the echo message is sent to the opposite end. The opposite terminal is connected with the sending terminal and periodically sends BFD echo messages, the opposite terminal does not process the data messages, and only forwards the data messages and then sends the data messages back to the sending terminal. Therefore, whether the uplink is stable is detected according to whether the BFD session message can be received or not.
The BFD protocol provides a universal standardized media independent and protocol independent fast failure detection mechanism with the following advantages: providing light load, fast failure detection for channels between adjacent forwarding engines. These failures include interfaces, data links, and possibly even the forwarding engine itself. And a single mechanism is used for detecting any medium and any protocol layer in real time. By adopting BFD, the forwarding communication state of a link or an IP route in a network can be rapidly detected and monitored, and the network performance is improved. The communication fault is found through rapid detection between adjacent systems (non-adjacent systems are linked with the route), so that a user can be helped to establish a backup channel to recover the communication more rapidly, and the reliability of the network is ensured. In this embodiment, "opposite end" and "sender" respectively correspond to the switches 10 and 20, and when there are three or more switches, the "opposite end" and "sender" respectively correspond to any pair of switches.
The method for executing stability detection on the first physical interface by adopting the dynamic routing protocol specifically comprises the following steps: and detecting the stability of all configured uplinks based on the first physical interface by adopting an OSPF protocol or a BGP protocol.
When the dynamic routing protocol (for example, OSPF protocol) is running, the adjacency state of the OSFP is dynamically detected, and when the adjacency state changes from Loading to Full, it indicates that the adjacency state Loading Done is up, which means that the uplink channel has been stabilized. When a dynamic routing protocol (e.g., the BGP protocol) is running, it is dynamically detected whether BGP establishes a stable connection with a switch located in the uplink. BGP establishes a neighbor relation with a switch in an uplink, establishes TCP connections and releases routes mutually, simultaneously has Keepalive information to maintain the neighbor relation, and can know whether BGP establishes stable network connection with the switch in the uplink through the neighbor relation and the health state of Keepalive, thereby judging whether the uplink is stable.
When the static routing protocol and the dynamic routing protocol are adopted to execute stability detection on the first physical interface and the first physical interface is considered to be in a stable state, the PORT-2 or PORT-4 is opened, so that the data message to be forwarded between the processing equipment 40 and the external network 30 is forwarded through a data message forwarding channel formed by the PORT-2 or PORT-4; and as long as the static routing protocol or the dynamic routing protocol is adopted to detect that the first physical interface is in an unstable state, the establishment of a data message forwarding channel is refused to prevent the occurrence of faults such as packet loss, response delay and the like.
Step S2, establishing at least two data packet forwarding channels between the extranet 30 and the processing device 40 through the first physical interface and the second physical interface; the first physical interface and the second physical interface are provided in a pair in the same switch, and all switches are connected to the processing device 40.
In this embodiment, a failover mechanism is operated among the switches, and the unicast or broadcast data packet in the data packet forwarding channel with the network failure is switched to any one or several other healthy data packet forwarding channels through the failover mechanism, and a forwarding operation is performed, so as to implement HA switching (high availability switching), and no core switch needs to be switched in the process of implementing HA switching, so that the network configuration of the entire computing device 100 is more reliable. Meanwhile, the switching of the data packet forwarding channels may be implemented based on two or more switches to implement the device-level data link switching, or based on one switch to implement the port-level data link switching, and implemented by relying on the aggregation port 41 disclosed below.
Preferably, in this embodiment, the method further includes: the uplink is rejected in the three-layer network 31 between the unstable first physical interface and the outer network 30. Whether the uplink to be established between the first physical interface and the external network 30 is stable is determined by detecting PORT-1 based on the aforementioned static routing protocol or dynamic routing protocol.
As shown in fig. 3, the processing device 40 configures a plurality of physical network cards, and aggregates ports of the physical network cards to form an aggregated port 41; the aggregation port 41 receives a service request issued from the switch, and sends a data packet with a source MAC address as the MAC address of the processing device and a destination MAC address as the MAC address corresponding to the aggregation port 41 to the switch by using an ARP table. After the switch receives the data packet sent by the processing device 40, the switch replaces the source MAC address included in the data packet with the MAC address included in the first physical interface exposed by the switch to the external network, and replaces the destination MAC address with the MAC address of the next-hop device, and forwards the destination MAC address to the external network. The plurality of physical network cards configured by processing device 40 perform binding (Teaming) to expose a virtual network card with a unique IP address to all switches. Specifically, the learning is to bind a plurality of physical network cards (i.e., NIC-1 and NIC-2) on the same server (a lower concept of the processing device 40) into one virtual network card (also referred to as a "virtual network adapter") through software. For the extranet 30, the server has only one visible network card, i.e., a virtual network card. For any application and the network where the server is located, the server has only one network link or only one accessible IP address. In this embodiment, by using a technical means of binding (Teaming) the plurality of physical network cards configured in the processing device 40, not only the network speed can be increased by using the plurality of physical network cards to work simultaneously, but also Load Balancing (Load Balancing) and network card redundancy (Fault Tolerance) between different physical network cards can be realized by Teaming.
Meanwhile, the switch may be connected to a processing device 40, and may also be connected to a processing device 42 and/or a processing device 43 through an aggregation port 41. Processing device 40, processing device 42, or processing device 43 is at least one server or a cluster server comprised of at least one server. The server includes but is not limited to a physical server with independent computing and storing functions, a bare metal server and the like. Referring to fig. 3, when it is detected that a data packet forwarding channel between the external network 30 and the switch 10 and the processing device 40 cannot be established based on the foregoing technical solution, the data packet is forwarded by the data packet forwarding channel 80 or the data packet forwarding channel 81 through the switch 10 between the external network 30 and the processing device 40. Meanwhile, the processing device 40 may also mount a physical machine 51 and/or a physical machine 52 (note: the number of physical machines is not limited to two), and the physical machines 51 and 52 are located in the device layer 33. The physical machines 51 and 52 may also be understood as local disks or shared storage devices.
Example two:
referring to fig. 3, based on the technical solutions included in the method for controlling forwarding of data packets according to the first embodiment, the present embodiment further discloses a computing device 100, where the computing device 100 and the external network 30 perform unidirectional and/or bidirectional data packet forwarding operations. The data packets may be based on execution of a user-initiated request by the computing device 100 in response to the user's request to generate corresponding data packets, as such data packets establish data links in the north-south direction in fig. 3, and the data links include uplink data links (i.e., uplinks) between the plurality of connecting switches and the external network 30, and downlink data links (i.e., downlinks) between the plurality of connecting switches and the one or more serving devices.
The computing device 100 includes: at least one processing device 40, at least two switches connected to the processing device 40, i.e. switch 10, switch 20 to switch N in fig. 3; the switch disclosed in this embodiment (i.e. the aforementioned switch 10 to switch N) accesses the external network 30 through a first physical interface, and the switch is connected to the processing device 40 through a second physical interface; when the processing device 40 and the external network 30 perform data packet forwarding, the method for controlling data packet forwarding according to the first embodiment is performed.
The method for controlling forwarding of data packets included in the computing device 100 disclosed in this embodiment is similar to the technical solution of the same part in the first embodiment, please refer to the description of the first embodiment, and will not be described herein again.
In addition, functional units in the embodiments of the present invention may be integrated into one processing unit, or each unit may exist alone physically, or two or more units are integrated into one unit.
