Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The cloud physical machine is a high-performance cloud computing resource different from a cloud virtual machine. When the user uses the cloud physical machine, all computing resources of the user can be obtained, and virtualization overhead does not need to be borne. In order to enable a user to connect to a VPC (Virtual Private Cloud) network, a Cloud physical machine needs to be equipped with an intelligent network card. The intelligent network card is provided with an independent operating system for an IaaS (Infrastructure as a Service) operator to use. All messages sent by the user through the intelligent network card can be packaged in the virtual switch running on the intelligent network card, so that the tenant is prevented from directly contacting the physical network.
Under the condition that the bandwidth provided by the intelligent network card is insufficient, the configuration number of the intelligent network card needs to be increased on the cloud physical machine. However, after the cloud physical machine is equipped with the multiple intelligent network cards, the multiple intelligent network cards need to be used separately because the ports of the multiple intelligent network cards cannot be aggregated.
Based on this, each time the application program on the cloud physical machine connects to the network, it needs to explicitly select one from a plurality of local virtual network IPs (Internet Protocol) as a source IP and specify one from a plurality of virtual network IPs at the opposite end as a destination IP, otherwise, all the outgoing flows can only use one of the intelligent network cards, and the bandwidths of the plurality of local intelligent network cards cannot be fully used.
Therefore, in the related art, in a use scene where the cloud physical machine is equipped with the multiple intelligent network cards, the multiple intelligent network cards need to be separately used, so that a lot of inconvenience is caused in application, and the broadband of the multiple intelligent network cards cannot be effectively utilized.
In order to solve the above problems in the related art, the embodiments of the present disclosure provide an intelligent network card assembly.
As shown in fig. 1, the smart network card assembly according to the embodiment of the present disclosure includes a plurality of smart network card sets.
Specifically, the intelligent network card sets are configured on the corresponding physical machines, that is, each intelligent network card set is configured corresponding to a single physical machine, and the intelligent network card set includes a plurality of intelligent network cards. The communication ports of the intelligent network cards communicate with the physical machine by using an LACP (Link Aggregation Control Protocol), and in any intelligent network card group, data units fed back to the physical machine by the communication ports of the intelligent network cards are configured to be the same to form an Aggregation port group of the intelligent network card group, wherein the data units include Media Access Control (MAC) addresses and operation keys (Key values) of the intelligent network cards.
It should be noted that the LACP protocol is a protocol based on the ieee802.3ad standard (standard method for performing link aggregation). And the communication port of each intelligent network card adopts an LACP protocol, and realizes information interaction with the opposite-end physical machine by feeding back a data unit to the physical machine. The Data Unit fed back to the physical machine by the communication port of each smart network card may be a Link Aggregation Control Protocol Data Unit (LACPDU). The interface in the dynamic aggregation group can automatically use the LACP, and the interface informs the opposite physical machine of the own system LACP priority, the system MAC, the LACP priority of the port, the port number and the operation Key by sending a link aggregation control protocol data unit.
And after receiving the link aggregation control protocol data units sent by each intelligent network card, the physical machine at the opposite end compares the information in the link aggregation control protocol data units, and determines the communication port of the intelligent network card with the same MAC address and operation Key as a selection state. The MAC addresses and the operation keys of the intelligent network cards in the link aggregation control protocol data units sent by the intelligent network cards to the physical machine are configured to be the same, so that the intelligent network cards in the same intelligent network card group can keep the communication ports in a selected state to be consistent, the communication ports of the intelligent network cards in the intelligent network card group can be gathered into an aggregation port group, and the opposite-end physical machine can perform information interaction with the intelligent network cards through the information ports in the aggregation port group.
Illustratively, as shown in fig. 1, the smart network card assembly may include a first set of smart cards communicating with the first physical machine and a second set of smart cards communicating with the second physical machine. The first intelligent network card group comprises a first intelligent network card and a second intelligent network card, the first intelligent network card and the second intelligent network card are communicated with the first physical machine through the aggregation port group of the first intelligent network card group, and the communication ports of the first intelligent network card and the second intelligent network card are communicated with the first physical machine respectively through an LACP protocol. The second intelligent network card set comprises a third intelligent network card and a fourth intelligent network card, the third intelligent network card and the fourth intelligent network card are communicated with the second physical machine through the aggregation port set of the second intelligent network card set, and the communication ports of the third intelligent network card and the fourth intelligent network card are communicated with the second physical machine respectively through an LACP protocol.
The data units fed back to the first physical machine by the communication ports of the first intelligent network card and the second intelligent network card are the same, so that a convergence port group of the first intelligent network card group is formed. The communication ports of the third intelligent network card and the fourth intelligent network card are the same as the data units fed back to the second physical machine so as to form a convergence port group of the second intelligent network card group.
It should be understood that the above is only an illustrative example, and not a limitation to the present disclosure, for example, the number of the intelligent network card sets may be multiple, the number of the intelligent network cards in each intelligent network card set may be any, and the number of the intelligent network cards in different intelligent network card sets may be the same or different. The number of the intelligent network card sets can be specifically set according to the number of the physical machines, and the number of the intelligent network cards in the intelligent network card sets can be specifically set according to the broadband requirement of the opposite-end physical machine.
According to the intelligent network card assembly disclosed by the embodiment of the disclosure, the communication ports of the intelligent network cards are communicated with the physical machine by adopting an LACP (Link Aggregation Control Protocol) Protocol, and the data units fed back to the physical machine by the communication ports of the intelligent network cards in any intelligent network card group are configured to be the same, so that the communication ports of the intelligent network cards in the intelligent network card group can be aggregated into an Aggregation port group according to the LACP Protocol. Therefore, when the application program on the opposite-end physical machine is used, because the data units fed back by the intelligent network cards of the corresponding intelligent network card group are the same, the opposite-end physical machine can utilize the communication port of any intelligent network card to carry out information interaction, so that the opposite-end physical machine can randomly use the intelligent network cards in the intelligent network card group, and a source IP and a destination IP do not need to be explicitly selected from a plurality of local virtual network IPs, a plurality of intelligent network cards in the intelligent network card group can be used by the application program of the opposite-end physical machine in a transparent mode, and the broadband of the intelligent network cards in the intelligent network card group can be fully utilized.
In one embodiment, as shown in fig. 1, the intelligent network card is configured with a virtual switch, and the virtual switches of different intelligent network card groups communicate with each other through a tunnel. In other words, the virtual switches of any two intelligent network cards in different intelligent network card groups communicate with each other through a tunnel. The virtual switch of the intelligent network card is provided with a tunnel port group, and the tunnel port group is obtained by combining a plurality of tunnels between the virtual switch and virtual switches of other intelligent network card groups.
It will be appreciated that tunneling is a way of transferring data between networks by using the infrastructure of the internetwork. The messages that are tunneled may be data frames or packets of different protocols. The tunnel re-encapsulates the messages of these other protocols in a new header for transmission. The new header provides routing information to enable encapsulated payload data to be transferred between different smart card cards over the internet.
As shown in fig. 1, two endpoints of the tunnel are respectively located between two intelligent network cards of different intelligent network card groups, for example, information is exchanged between a first virtual switch of a first intelligent network card and a third virtual switch of a third intelligent network card through a first tunnel (1-3). The encapsulated packet is routed between the two endpoints of the tunnel through the public internetwork. The logical path through which the encapsulated packet travels over the public internetwork is called a tunnel. Once the network endpoint is reached, the data will be unpacked and forwarded to the final destination. In other words, tunneling refers to the overall process including encapsulation, transmission, and unpacking of a message.
The tunnel can make a mechanism that a virtual switch of two different intelligent network cards can transmit messages on an incompatible transmission network feasible, thereby allowing a user using a VPC network to obtain the authority of accessing other intelligent network cards. Also, the tunnel may use data encryption to transmit the message, ensuring that the encapsulated message may be displayed as public data. And the information interaction can be realized for the virtual switch of any two intelligent network cards of different intelligent network card groups.
Illustratively, according to the division of the Open System Interconnection communication Reference Model (OSI Model), a tunnel may be a two-Layer Tunneling Protocol or a three-Layer Tunneling Protocol, wherein the two-Layer Tunneling Protocol uses a frame as a data exchange unit, such as PPTP (Point to Point Tunneling Protocol) or L2TP (Layer 2Tunneling Protocol), which both encapsulate a message and transmit through the Internet in a Point to Point Protocol frame.
In a specific example, as shown in fig. 1, in the first intelligent network card, a first virtual switch of the first intelligent network card communicates with a third virtual switch of a third intelligent network card through a first tunnel (1-3); and the first virtual switch of the first intelligent network card is communicated with the fourth virtual switch of the fourth intelligent network card through a second tunnel (1-4). Wherein, 1-3 indicates that two endpoints of the first tunnel are respectively connected with the first virtual switch and the third virtual switch, and 1-4 indicates that two endpoints of the second tunnel are respectively connected with the first virtual switch and the fourth virtual switch. The first tunnel and the second tunnel jointly form a tunnel port group for the communication between the first virtual switch and the second intelligent network card group.
In the second intelligent network card, communication is carried out between a second virtual switch of the second intelligent network card and a third virtual switch of a third intelligent network card through a third tunnel (2-3); and the second virtual switch of the second intelligent network card is communicated with the fourth virtual switch of the fourth intelligent network card through a fourth tunnel (2-4). Wherein, 2-3 indicates that two endpoints of the third tunnel are respectively connected with the second virtual switch and the third virtual switch, and 2-4 indicates that two endpoints of the fourth tunnel are respectively connected with the second virtual switch and the fourth virtual switch. The third tunnel and the fourth tunnel form a tunnel port group for the communication between the second virtual switch and the second intelligent network card group.
Similarly, the first tunnel and the third tunnel form a tunnel port group for the third virtual switch to communicate with the first intelligent network card group; the second tunnel and the fourth tunnel form a tunnel port group for the fourth virtual switch to communicate with the first intelligent network card group.
It will be appreciated that the number of sets of tunnel ports on the virtual switch of each intelligent network card is related to the number of sets of intelligent network cards. Specifically, the number of the intelligent network card groups is N (N is greater than or equal to 2), and the number of the tunnel port groups on the virtual switch of each intelligent network card is N-1. For example, in fig. 1, if the number of the intelligent network card sets is 2, the number of the tunnel port sets on the virtual switch of each intelligent network card is 1.
The multiple tunnels between the intelligent network card and the multiple intelligent network cards of a certain intelligent network card group are combined into the tunnel port group, so that the multiple tunnels can be uniformly deployed and managed aiming at the virtual switch of each intelligent network card, and the hash table can be constructed based on the tunnel port group, thereby providing convenience for determining the intelligent network card for message transmission by using the hash algorithm.
According to an embodiment of the present disclosure, the present disclosure also provides a physical machine.
As shown in fig. 1, a physical machine according to an embodiment of the present disclosure communicates with an aggregation port group of an intelligent network card assembly.
The intelligent network card component may be the intelligent network card component of the above embodiments of the present disclosure, and is not described herein again.
According to the physical machine disclosed by the embodiment of the disclosure, the broadband of each intelligent network card in the intelligent network card set can be effectively utilized through the communication with the aggregation port group of the intelligent network card set of the intelligent network card assembly, so that the network performance of the physical machine is improved, and the use experience of a user is further improved.

The communication ports of the third intelligent network card and the fourth intelligent network card are the same in data unit fed back to the second physical machine so as to form a convergence port group of the second intelligent network card group.
In the first intelligent network card, a first virtual switch of the first intelligent network card communicates with a third virtual switch of a third intelligent network card through a first tunnel (1-3); and the first virtual switch of the first intelligent network card is communicated with the fourth virtual switch of the fourth intelligent network card through a second tunnel (1-4). Wherein, 1-3 represents that two endpoints of the first tunnel are respectively connected with the first virtual switch and the third virtual switch, and 1-4 represents that two endpoints of the second tunnel are respectively connected with the first virtual switch and the fourth virtual switch.

For example, the header of the network message may be a message header of the network message at a network layer or a transport layer, etc.
According to the message sending method of the physical machine, the intelligent network card for forwarding the network message can be reasonably determined in the intelligent network card group communicated with the source physical machine by determining the first target intelligent network card through the Hash algorithm, so that the balanced distribution and the use of a plurality of intelligent network cards in the intelligent network card group are realized.
As shown in fig. 3, in one embodiment, step S201 may include:
step S301: acquiring a source mark and a destination mark of the network message according to the header of the network message;
step S302: constructing a first key value based on the source mark and the destination mark, wherein the first key value is characterized from the source mark to the destination mark;
step S303: and determining a first target intelligent network card from the intelligent network card group corresponding to the source physical machine by utilizing a Hash algorithm based on the first keyword value.
For example, the source identifier of the network packet may include a source IP address of the network packet or a source port number of the network packet, and the destination identifier of the network packet may include a destination IP address of the network packet or a destination port number of the network packet. The first key value may be characterized as (src- > dst), where src (source) is a source tag of the network packet, dst (destination) is a destination tag of the network packet, and the first key value is a forward sending direction of the network packet from the source tag to the destination tag. Therefore, the sending path from the source mark to the destination mark of the network message can be determined by utilizing the Hash algorithm, and the object, namely the first destination intelligent network card, of the network message sent by the source physical machine is determined according to the sending path.
Through the embodiment, the first key value is constructed from the source mark to the destination mark of the network message, and the first destination intelligent network card which is transmitted by the source physical machine and passes through the network message in the forward transmission direction can be determined by using the hash algorithm based on the first key value, so that a plurality of intelligent network cards which are communicated with the source physical machine can be ensured to be used in a balanced manner.
As shown in fig. 4, in one embodiment, the method further comprises:
step S401: and under the condition that any one intelligent network card is detected to be abnormal, generating fault information, and synchronizing the fault information to other intelligent network cards by using the aggregation port group.
Illustratively, whether the intelligent network card is abnormal or not can be judged through a Media Independent Interface (MII) of the physical machine, and when the intelligent network card is detected to be abnormal, a control network of the physical machine generates fault information and synchronizes the fault information to a plurality of intelligent network cards which are communicated with the physical machine by utilizing an aggregation port group. In addition, the intelligent network card can also detect whether the intelligent network card is abnormal or not by using the activity detection mechanism through the network control plane, and generates fault information under the condition of detecting that the intelligent network card is abnormal, and synchronizes the fault information to the intelligent network cards in other intelligent network card groups through the tunnel.
Through the embodiment, the intelligent network card can be subjected to abnormity detection, and fault information is synchronized to other intelligent network cards under the condition that the intelligent network card sends abnormity, so that the tunnels of the intelligent network cards which are selected by the other intelligent network cards and go to the fault intelligent network card are shielded, and the stability of information interaction between the intelligent network card assembly and a physical machine is ensured.
According to the embodiment of the disclosure, the disclosure also provides a message sending method of the intelligent network card assembly.
As shown in fig. 5, the method for sending a message by an intelligent network card component includes:
step S501: determining a destination tunnel port group from a plurality of tunnel port groups of a virtual switch of a first destination intelligent network card according to a header of a network message;
step S502: determining a target tunnel and a second target intelligent network card by using a Hash algorithm according to the header of the network message;
step S503: sending the network message to a second target intelligent network card through the target tunnel;
step S504: and transmitting the network message to the target physical machine by using the aggregation port group of the intelligent network card group corresponding to the second target intelligent network card.
For example, in step S501, a destination physical machine corresponding to the destination virtual network may be obtained according to the IP address of the destination virtual network of the network message in the header of the network message, and a destination tunnel port group corresponding to the intelligent network card group may be determined from a plurality of tunnel port groups of the virtual switch of the first destination intelligent network card according to the intelligent network card group communicating with the destination physical machine. For example, in the example shown in fig. 1, the source physical machine is a first physical machine, and the first destination smart network card is a first smart network card. The header of the network message comprises a destination virtual network IP address, the destination virtual network IP address is a virtual network IP2, the destination physical machine for obtaining the network message is a physical machine B corresponding to the virtual network IP2, and then a second intelligent network card group communicated with the physical machine B is obtained. And in the first virtual switch of the first intelligent network card, selecting a tunnel port group corresponding to the second intelligent network card group from the plurality of tunnel port groups as a target tunnel port group.
For example, in step S502, a hash table may be constructed based on the header of the network packet and the transmission path of the packet. The header of the network packet may be used as a key value of the hash table, and the transmission path of the packet may be a key value. After the key value is obtained based on the header of the network message, the corresponding key value is obtained in the hash table by using the hash algorithm, the sending path of the network message is obtained, finally, a second target intelligent network card is determined from an intelligent network card group communicated with a target physical machine according to the sending path of the network message, and a target tunnel is determined from a target tunnel port group.
For example, the header of the network message may be a message header of the network message at a network layer or a transport layer, etc.
According to the message sending method of the network card assembly, the second target intelligent network card which is communicated with the target physical machine is determined by utilizing a Hash algorithm according to the header of the network message, then the network message is sent to the second intelligent network card through the first intelligent network card, and finally the message is sent to the target physical machine through the aggregation port group of the intelligent network card group where the second intelligent network card is located. Therefore, message forwarding of the intelligent network card assembly between different physical machines can be achieved.
As shown in fig. 6, in one embodiment, step S501 includes:
step S601: acquiring a source mark and a destination mark of the network message according to the header of the network message;
step S602: constructing a second key value based on the source mark and the target mark, wherein the second key value is characterized from the target mark to the source mark;
step S603: and based on the second keyword value, determining a target tunnel from the target tunnel port group by utilizing a Hash algorithm, and determining a second target intelligent network card from a group of intelligent network cards communicated with the target physical machine.
For example, the source identifier of the network packet may include a source IP address of the network packet or a source port number of the network packet, and the destination identifier of the network packet may include a destination IP address of the network packet or a destination port number of the network packet. The second key value may be characterized as (dst- > src), where src (source) is a source tag of the network packet, dst (destination) is a destination tag of the network packet, and the second key value is a reverse sending direction of the network packet from the destination tag to the source tag, that is, the second key value is a sending direction of a reverse packet opposite to the network packet.
It is understood that the hash function has the following basic characteristics: if the key values are not the same (according to the same function), then the key values of the two hash values are also not the same. This property is the result of the hash function being deterministic. But on the other hand, the input and output of the hash function are not one-to-one, and if two key values are the same, then the two key values are likely to be the same. Therefore, a reverse sending path from the target mark to the source mark of the network message can be determined by using the Hash algorithm, and an object, namely a second target intelligent network card, of the first target intelligent network card for sending the network message is determined according to the reverse sending path of the network message.
Through the implementation mode, the target mark to the source mark of the network message is constructed into the second keyword value, and based on the second keyword value, the hash algorithm is utilized, so that not only can the forward sending object of the network message, namely the second target intelligent network card be determined, but also the reverse message sent by the target physical machine can be ensured to return to the source physical machine along the reverse sending path opposite to the forward sending path of the network message, and thus the connection tracking of the network message in the forward direction and the reverse direction can be realized.
