Description
Technical Field
The present disclosure relates to the field of cloud technologies, and in particular, to a method, an apparatus, and a system for data forwarding.
Background
The cloud technology is a technology for unifying series resources such as hardware, software, networks and the like in a wide area network or a local area network to realize data calculation, storage, processing and sharing, and has the basic characteristics of Virtualization (Virtualization) and distribution, wherein the Virtualization technology abstracts and converts computer resources such as servers, networks, memories, storage and the like and then presents the computer resources, for example, a virtual machine implementation mode is used, so that a user can better apply the resources without the limitation of conditions such as physical forms, regions and the like of the existing resources. The distributed network storage technology dispersedly stores data on a plurality of independent machine devices, thereby not only solving the bottleneck problem of a single storage server in the traditional centralized storage system, but also improving the reliability, the availability and the expansibility of the system.
At present, various clouds realized by using a cloud technology are often built by a large number of servers.
A common network deployment method for accessing a server to a network is shown in fig. 1, where servers in a same Rack are all connected to a Top switch (ToR) of an entity located at the Top of a cabinet, and the Top switches of different cabinets are further connected to a convergence switch. Therefore, a plurality of virtual machines on the server can be connected with the set-top switch through the virtual switch (vSwtich) belonging to the same server, so that network access and data forwarding are realized.
The physical carrier of the existing virtual switch is usually a CPU or a physical network card of a server, and each server is provided with a virtual switch, which has the advantage of reducing the fault domain by a distributed manner, but because the virtual switch usually needs a higher configured network card, such as a network card configured with a Programmable logic device (FPGA), or is implemented by using a CPU, the disadvantage is that the hardware cost of the server is higher, or the problem of occupying the system resource of the server and having higher power consumption is caused.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In order to solve the problems of high hardware cost, occupation of server system resources and high power consumption of a server caused by a network access mode of the server in the prior art, the embodiment of the disclosure improves the access mode of the existing server, thereby improving a data forwarding mode of the server.
Before describing the data forwarding method provided by the embodiment of the present disclosure, a network architecture of an access manner of a server corresponding to the embodiment of the present disclosure is briefly described.
Referring to fig. 2, in the embodiment of the present disclosure, a virtual switch is moved up to a set-top switch, more than one server is connected to the same virtual switch through its own network card, and meanwhile, the server may have one or more virtual machines, so that each virtual machine may be connected to the virtual switch through the network card of the server.
In the context of one or some embodiments, multiple set-top switches are connected to the same aggregation switch at an upper level of the set-top switches.
It should be noted that, in the technical solution provided in the embodiment of the present invention, the server may be various types of servers, including but not limited to various cloud servers structured as a cloud, an application server implementing some specific applications, a data server, and the like, and the embodiment of the present invention is not limited specifically.
Alternatively, as shown in fig. 2, because a plurality of servers share one virtual switch, based on disaster tolerance considerations, a plurality of virtual switches may be required to be mutually prepared, and similarly, a plurality of set-top switches (a set-top switch may integrate at least one virtual switch) are also required, so that different interfaces of the network card on each server may be connected to different virtual switches.
In one embodiment, to better guarantee the performance of the virtual switch, in the set-top switch, the virtual switch may be implemented using a separate chip, the processing of the data link layer of the virtual switch, and the like, may be implemented using software embedded in the chip. The virtual switch is realized by using a single chip, and the performance of the virtual switch can be ensured on the aspect of hardware forwarding efficiency so as to meet the requirement of serving a plurality of servers.
Correspondingly, the server no longer takes charge of the function of the virtual switch, specifically, the network card on the server no longer realizes the function of the virtual switch, so compared with the prior art, the network card can adopt the network card with simpler function and lower cost, and can realize the forwarding of the physical layer without processing the OSI two layer, namely the data link layer.
One possible implementation manner is shown in fig. 3, the network card uses a bypass (bypass) manner to implement data forwarding.
By means of bypass, network card and connected virtual switch can be connected directly physically, network card can not process data link layer for packet in network, and process data link layer when forwarding by virtual switch.
Based on the above networking manner, the data packet of the virtual machine on the server is forwarded to the virtual switch through the network card of the server, and then the virtual switch forwards the data packet to the aggregation switch through the top switch, so as to perform subsequent further forwarding processing.
Based on the network deployment mode, the method for forwarding data provided by the embodiment of the present disclosure, for the network card of the server, as shown in fig. 4, executes the following steps:
s41, receiving an uplink data message sent by the virtual machine, and determining an interface needing to process the uplink data message;
and S42, according to the determined interface, sending the uplink data message to the virtual switch connected with the interface through the interface for forwarding.
The above-described flow may be implemented by, for example, a network card on a server.
The virtual switch is arranged in the set-top switch, and when the network card of the server receives the uplink data message sent by the virtual machine, the interface of the network card, which needs to process the uplink data message, is determined first, and then the uplink data message is sent to the virtual switch connected with the interface and positioned on the set-top switch through the interface to be forwarded according to the determined interface. Compared with the prior art, the virtual switch is moved forward to the set-top switch from the server side, so that a plurality of servers (for example, located on the same rack) can be connected with one virtual switch, the same virtual switch is enabled to multiplex and forward data messages of virtual machines on the plurality of servers, the forwarding multiplexing ratio of the virtual switch is improved through the centralized virtual switch, on one hand, the hardware cost of the servers can be reduced, on the other hand, the virtual switch is arranged in the set-top switch in front, the virtual switch does not need to be arranged in each server, the virtual switch can be shared by the plurality of servers, and each server does not need to be used for the function of the virtual switch, so that the system resources can be more effectively utilized, and the power consumption of the servers is reduced.
Because multiple servers in the same enclosure share one virtual switch for communication, for disaster tolerance, in one or more possible embodiments, as also shown in fig. 2, two or more virtual switches may be provided in the same enclosure, and accordingly, the set-top switch may also be provided in multiple numbers because the virtual switch is provided in the set-top switch. The virtual switches are backup with each other, and share the communication work of a plurality of servers in the same cabinet according to a preset strategy, such as a load balancing strategy.
For stateful services, it is necessary to keep the incoming and outgoing paths of data packets in different directions, i.e. uplink and downlink, of the same Session (Session) consistent.
Stateful services are in contrast to stateless services, which refers to any state in which a service providing a service does not retain interaction with a client. That is, the last request has no influence on the current request, and the server does not perform any recording process on the last request of the client. Otherwise, the service with the state needs to record the state of the last interaction with the client, so as to process the subsequent request and response of the client again.
For example, a stateful service is described, for example, a user logs in a certain service platform by using a user name and a password, and a data message generated in a subsequent service processing process needs to be operated for the logged-in user, and it is not necessary to perform a login operation in advance before each request.
For stateful services, the same Session will be used, which means both the meaning of "connection oriented" or "hold state". In a scenario that a client accesses a server through a browser, when the client browser accesses the server, the server records client information in some form on a server, which is Session (i.e., stateful). When the client browser accesses again, the client state only needs to be searched from the Session.
If two or more virtual switches are connected to a server in the same cabinet at the same time, the following problems may occur: for a Virtual Machine (VM) in a server, data messages in two directions of the same Session entering and exiting the VM may pass through different virtual switches, so that for a stateful service scenario, feedback (action) in one direction depends on a message coming in the opposite direction; if the access paths are not consistent, the virtual switch is lack of dependence, unexpected feedback may be generated, and a problem of software implementation logic may be caused, or for the case that the user accesses the server using the browser, the last message is that the user logs in the server using the user name and the password, and a response message of successful login of the server reaches an interface of another network card through the same virtual switch, so that the network card cannot return the message to the virtual machine initiating the login request, and the login operation only can obtain a failure result.
In order to avoid the above situation, the embodiments of the present disclosure provide the following detailed description.
In an embodiment, the above steps determine the interface on the network card that needs to process the data packet, and when the method is implemented specifically, the method may be implemented by the following steps:
1. determining IP quintuple information in an uplink data message;
IP quintuple information, comprising: source IP address, source port, destination IP address, destination port, and transport layer protocol. For example: 192.168.1.110000TCP 121.14.88.7680 constitutes an IP quintuple. It means that a terminal with an IP address of 192.168.1.1 is connected via port 10000 using the TCP protocol (transport layer protocol) and a terminal with an IP address of 121.14.88.76 and a port of 80.
2. And searching a sending interface corresponding to the determined IP quintuple information from a mapping relation between the pre-stored IP quintuple information and a sending interface identifier according to the determined IP quintuple information.
In specific implementation, for convenience of query, the mapping relationship between the IP quintuple information and the sending interface identifier may be stored in the database in a mapping relationship table.
The IP quintuple information in the uplink data message comprises the following components: source IP address, source port, destination IP address, destination port, and transport layer protocol. And after the IP quintuple information is extracted from the uplink data message, searching the identifier of the sending interface corresponding to the extracted IP quintuple information according to the mapping relation of the prestored IP quintuple information and the identifier of the sending interface.
In order to ensure that the paths of the messages entering and exiting in different directions of the same Session are consistent, in the embodiment of the disclosure, a mapping relationship between an IP quintuple and the network card upper interface identifier is pre-stored, and when an uplink data message is sent, by querying the mapping relationship, a receiving interface of a downlink data message which is received last time and belongs to the same Session at this time can be used to send the uplink data message.
Because the quantity of IP quintuple information that the server and the virtual switch need to support is huge, for example, it can reach millions of orders in some scenarios, in this case, a simple network card itself, or a Memory of the virtual switch itself (such as a Static Random-Access Memory (SRAM)) may be difficult to support such a large Data storage amount, and therefore, a plug-in Memory, such as a Memory supporting fast reading and writing, such as a Double-Rate synchronous dynamic Random Access Memory (Double Data Rate SDRAM), may be adopted to store the IP quintuple information with huge Data volume and the information of the identifier of the interface, so as to meet the requirement of Data forwarding.
Before the step of searching for the sending interface corresponding to the determined IP quintuple information, referring to fig. 5, the following steps may be performed:
s51, determining the state corresponding to the IP quintuple information as an initial state or a non-initial state; if the state is the initial state, the following step S52 is executed; otherwise, the following step S53 is executed;
the initial state represents that the uplink data message containing the IP quintuple information is not sent, and the non-initial state represents that the uplink data message containing the IP quintuple information is sent;
s52, selecting a sending interface from each interface of the network card, and creating a mapping relation between IP quintuple information of the data message and a sending interface identifier;
if the IP quintuple has never sent the corresponding uplink data packet, the sending interface may be selected in multiple possible ways, for example, a default interface is pre-selected for each IP quintuple information, and in the initial state of the unsent data packet, the preset default interface is directly used.
Or other selection means are adopted, for example, hash operation (hash) is performed on each IP quintuple information, and an interface which needs to send the uplink data message is selected from the interfaces of the network card according to the hash operation result.
However, the embodiments of the present disclosure do not limit the specific ways of selecting the interface for sending the uplink report from the interfaces of the network card, and any realizable way may be adopted.
S53, searching a sending interface corresponding to the determined IP quintuple information from the mapping relation of the prestored IP quintuple information and the sending interface identifier.
When the data packet corresponding to a certain IP quintuple information is in a non-initial state, and a long time passes, assuming that a preset duration is not received, the state of the data packet may be updated to the initial state again.
In order to ensure that an uplink data packet and a downlink data packet of the same Session pass through the same path, that is, pass through the same vSwitch, so as to prevent a stateful service from generating an unexpected response (action), in the generation process of the mapping relationship between the IP quintuple information and the sending interface, the sending interface is ensured to be a receiving interface of the downlink data packet of the same Session through the following processes:
when a network card of a server receives downlink data forwarded by a connected virtual switch, determining whether the downlink data message and an uplink data message belong to the same session according to IP five-tuple information of the downlink data message; if yes, replacing the sending interface identifier in the mapping relation between the IP quintuple information of the uplink data message and the sending interface identifier by using the receiving interface identifier of the downlink data message.
In the above process, when the downlink data packet is received, because the source IP address and the destination IP address in the IP quintuple information of the uplink data packet and the downlink data packet belonging to the same Session are opposite, that is, in the IP quintuple information of the uplink data packet, the source IP address is the destination IP address of the downlink data packet, the destination IP address is the source IP address of the downlink data packet, the source port is the destination port of the downlink data packet, and the destination port is the source port of the downlink data packet. Therefore, according to the IP quintuple information extracted from the downlink data packet, the IP quintuple information of the uplink data packet belonging to the same Session as the downlink data packet can be known, so that the sending interface identifier in the mapping relationship between the IP quintuple information and the sending interface identifier can be modified into the identifier of the receiving interface of the downlink data packet.
Through the processing, the IP quintuple information and the sending interface identifier in the mapping relation of the sending interface identifier can be kept consistent with the interface identifier of the downlink data message of the same session received last time in real time, so that the uplink data message and the downlink data message of the same session can enter and exit the same interface, the correct request and response of the stateful service can be ensured, and the correctness of the logic realization of the stateful service can be ensured.
In one embodiment, after a network card of a server determines a sending interface according to the mapping relationship between the IP quintuple information and a sending interface identifier, if it is determined that an interface which needs to forward an uplink data message fails, the uplink data message is sent to a virtual switch on another set-top switch connected to the interface which does not fail through an interface which does not fail in the network card for forwarding;
in order to continuously keep the same interface in and out for the sending and receiving of the subsequent messages, the mapping relation between the IP five-tuple information and the sending interface identifier needs to be modified, and based on the mapping relation, when the downlink data messages of the same conversation of the uplink data messages are received from the interface without faults, the sending interface identifier in the mapping relation between the IP five-tuple information of the uplink data messages and the sending interface identifier is replaced by using the identifier of the interface without faults.
If the subsequent failed interface recovers again, due to a fault reporting mechanism of the network card, when the interface recovers, the downlink data message also needs to be received again from the recovered interface, at the moment, if the network card determines that the failed interface recovers and the downlink data message received from the recovered interface, the IP quintuple information in the downlink data message is extracted, and the identifier of the recovered interface is recorded;
and according to the IP quintuple information extracted from the downlink data message, determining the IP quintuple information corresponding to the uplink data message belonging to the same session with the downlink data message by utilizing the interchange relationship of the source IP, the destination IP, the source port, the destination port and the like, and then replacing the sending interface identifier in the mapping relationship between the IP quintuple information and the sending interface identifier by using the recovered interface identifier.
For example, assuming that the downlink data packet is received via the recovered Port1, according to the IP quintuple information in the downlink data packet: 192.168.1.110000TCP 121.14.88.7680 can find out the corresponding IP quintuple information corresponding to the uplink data message belonging to the same session, namely: 121.14.88.7680 TCP 192.168.1.110000, then find the mapping relation between the IP five-tuple information and the sending interface identification, and modify the sending interface identification Port2 into Port 1.
The embodiment of the present disclosure further provides another data forwarding method, which is applied to a virtual switch side, and as shown in fig. 6, the method includes the following steps:
s61, the virtual switch receives the uplink data message forwarded by the network card of the server;
and S62, after the virtual switch processes the uplink data message by the data link layer, the virtual switch forwards the uplink data message by the set-top switch where the virtual switch is located.
The data forwarding method provided in the embodiment of the present invention improves the existing network access architecture and data forwarding manner, but it should be noted that the inventive concept is not limited to the implementation of the specific architecture and data forwarding among the server, the virtual switch, and the set-top switch, and can be widely applied to various possible network types, such as various public clouds, private clouds, and public-private hybrid clouds, etc., the execution main body and the participating object of the method can be devices in the various types of networks, such as an intelligent network card, an intelligent access gateway, a virtual switch, etc., and the flow of the embodiment of the present invention can be executed and the corresponding technical effect can be achieved, which is not limited in the embodiment of the present invention.
In order to better explain the data forwarding method provided by the embodiments of the present disclosure, two simple examples are described here, and in the two embodiments, a cloud server is taken as an example.
The first embodiment is as follows:
referring to an architecture diagram shown in fig. 7, in an example of a network architecture to which the first embodiment of the present disclosure is applied, network cards in a plurality of cloud servers (cloud server 1 to cloud server 3) in a cabinet 1 are all connected to virtual switches in a Bypass (Bypass) manner, each cabinet is equipped with two virtual switches, each switch is integrated in a set-top switch, and a plurality of set-top switches are connected to the same aggregation switch.
In the cloud server, a plurality of virtual machines are connected to a network through network devices such as a network card, a virtual switch, a set-top switch and a convergence switch of the cloud server.
The network card of the cloud server is a double-interface network card, each interface is connected with a virtual switch, and the identifiers of the interfaces are Port1 and Port 2; the connected virtual switches are virtual machine switch 1 and virtual switch 2, respectively.
In the internal memory of the network card, a table of the mapping relationship between the huge number of IP quintuple information and the sending interface identifier is stored, and the sending interface corresponding to any IP quintuple information can be determined through table lookup, and the table lookup process is called export lookup (Tx Port look up).
For each IP quintuple information, it corresponds to an identifier of an interface, and also has a state, an initial state or a non-initial state, where an initial state means that the IP quintuple information has never sent a message, and a non-initial state means that the IP quintuple information has sent a message.
When the virtual machine 1 in the cloud server 1 forwards the first uplink data packet of a certain session through the network card, the network card extracts IP quintuple information of the uplink data packet, that is: 192.168.1.110000TCP 121.14.88.7680, and enquires the state of IP quintuple information, if it is the initial state, it carries out Hash operation according to the IP quintuple information, according to the result of Hash operation, selects Port2 from Port1 and Port2 as sending interface, and creates the mapping relation between the IP quintuple information and the sending interface identification, and modifies the initial state into non-initial state.
When a downlink data message belonging to the same session with an uplink data message is forwarded to a set-top switch from a convergence switch, then the set-top switch is forwarded to a virtual switch 1, and is forwarded to a Port1 of a network card of a cloud server 1 through the virtual switch 1, the network card extracts IP quintuple information 121.14.88.7680 TCP 192.168.1.110000 of the downlink data message, interchanges a source IP and a destination IP, and interchanges a source Port and a destination Port to obtain IP quintuple information of the uplink data message of the same session, namely 192.168.1.110000TCP 121.14.88.7680, searches a corresponding entry from a mapping relation table of the stored IP quintuple information and a sending interface identifier, and updates a Port2 therein to a Port 1.
At the same time, the network card sends downstream data messages to virtual machine 1 using port 1.
The virtual machine 1 sends the uplink data message of the same session to the network card of the cloud server 1 again, after the network card reads the IP quintuple information of the uplink data message, the network card queries the mapping relation table of the stored IP quintuple information and the sending interface identifier, determines that the sending interface is Port1, forwards the IP quintuple information to the virtual switch 1 through the Port1 of the network card, processes the data link layer, sends the IP quintuple information to the aggregation switch through the set-top switch 1, and further forwards the IP quintuple information by subsequent routing and the like until the destination server is reached.
Through the operation, the sending interface of the same uplink data message is always consistent with the receiving interface of the last downlink data message, so that the smooth proceeding of the session of the stateful service and the correctness of the realization logic of the software are ensured.
Example two:
still referring to the network architecture of fig. 7, the network architecture to which the second embodiment of the present disclosure is applied is the same as the first embodiment, and the data forwarding process is also similar, in the second embodiment, when the uplink data packet needs to be forwarded, the network card checks that the Port1 interface of the network card suddenly fails, and cannot forward the uplink data packet normally, and at this time, the network card forwards the uplink data packet through the Port2 interface that does not fail.
The network card reports the message after the Port1 interface fails, so that the returned downlink data message is prevented from being forwarded to the virtual switch 1 and the set-top switch 1 connected with the Port1, and thus, the subsequent downlink data message is forwarded to the interface Port2 on the network card of the cloud server 1 from the virtual switch 2 and the set-top switch 2, when the downlink data message is subsequently received from the interface Port2, the IP quintuple information of the downlink data message is extracted, and after the source IP, the destination IP, the source Port and the destination Port are exchanged, the IP quintuple information of the corresponding uplink data message is obtained, a mapping table is searched, and the originally recorded Port1 is updated to be the Port 2.
Thus, the interface that sends the upstream data packet and the interface that receives the downstream data packet are both ports 2. Once the Port1 interface is recovered to normal, the message for recovering normal is further reported to the set-top switch and the aggregation switch, so that the downlink data packet is also sent to the Port1 interface of the cloud server 1 network card through the virtual switch 1, at this time, the IP quintuple information in the received downlink data packet is extracted, and the identifier of the Port1 interface is recorded;
and determining IP quintuple information corresponding to an uplink data message belonging to the same session with a downlink data message according to the extracted IP quintuple information, and replacing a sending interface identifier in the mapping relation between the IP quintuple information of the uplink data message and the sending interface identifier by using an identifier of a Port1 interface. The subsequent operations are again the same as the first embodiment, and are not described again here.
