Technical Field

Background

In order to fully utilize the bandwidth of multiple aggregated physical links to achieve ordered and reliable transmission of a standard User Datagram Protocol (UDP) packet, a link aggregation method is usually used to achieve scheduling and allocating traffic on the multiple physical links. The existing method for implementing link aggregation includes: (1) load sharing packet by packet: by causing a first data frame of a data stream to be transmitted over a physical link; and a second data frame is transmitted on another physical link. The method makes it possible for the second data frame of the same data flow to reach the opposite terminal device before the first data frame, so as to generate the condition that the received data packets are out of order. (2) Load sharing flow by flow: the addresses in the data frames are used for generating Hash key values through a Hash algorithm, then corresponding outgoing interfaces are searched in a forwarding table according to the Hash key values, the corresponding outgoing interfaces are different due to the fact that the obtained Hash key values are different, and the fact that the frames of the same data stream can be forwarded on the same physical link is achieved. However, although the stream-by-stream load sharing method can guarantee the sequential transmission of packets, it cannot guarantee the bandwidth utilization rate. Therefore, how to provide a more effective link aggregation method becomes a technical problem to be solved urgently.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It should be noted that although functional blocks are partitioned in a schematic diagram of an apparatus and a logical order is shown in a flowchart, in some cases, the steps shown or described may be performed in a different order than the partitioning of blocks in the apparatus or the order in the flowchart. The terms first, second and the like in the description and in the claims, and the drawings described above, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.

First, several terms referred to in the present application are resolved:

link Aggregation (Link Aggregation): the method is characterized in that a plurality of physical ports are converged together to form a logic port so as to realize load sharing of the throughput of the input/output flow on each member port, and the switch determines which member port the network packet is sent to the switch of the opposite end according to a port load sharing strategy configured by a user. When the exchanger detects that one member port link is fault, it stops transmitting package on the port, and recalculates the transmitting port of message in the rest links according to the load sharing strategy, and the fault port is recovered and then acts as the receiving/transmitting port again. Link aggregation is an important technology in terms of increasing link bandwidth, implementing link transmission resilience, engineering redundancy, and the like.

Internet Protocol (IP): is the core of the TCP/IP protocol family and also forms the basis of the Internet. The IP is located at a network layer of a Transmission Control Protocol/Internet Protocol (TCP/IP) model, and it can provide information of various protocols to a transport layer.

Transmission Control Protocol (TCP): is a connection-oriented, reliable, byte stream-based transport layer communication protocol.

User Datagram Protocol (UDP): the method is a connectionless transport layer protocol in an Open System Interconnection (OSI) reference model, and provides a transaction-oriented simple unreliable information transfer service.

Media Access Control Address (MAC Address): also known as local area network Address (LAN Address), Ethernet Address (Ethernet Address) or Physical Address (Physical Address), is an Address used to confirm the location of a network device.

Maximum Transmission Unit (MTU): is used to inform the other party of the maximum size of the data service unit that can be accepted, which indicates the size of the payload that can be accepted by the sender.

In order to fully utilize the bandwidth of multiple aggregated physical links to achieve ordered and reliable transmission of a standard User Datagram Protocol (UDP) message, a link aggregation method is usually adopted to achieve scheduling and allocating traffic on the multiple physical links. The existing method for implementing link aggregation includes: (1) load sharing packet by packet: by causing a first data frame of a data stream to be transmitted over a physical link; and a second data frame is transmitted on another physical link. The method makes it possible for the second data frame of the same data flow to reach the opposite terminal device before the first data frame, so as to generate the condition that the received data packets are out of order. (2) Load sharing flow by flow: the addresses in the data frames are used for generating Hash key values through a Hash algorithm, then corresponding outgoing interfaces are searched in a forwarding table according to the Hash key values, the corresponding outgoing interfaces are different due to the fact that the obtained Hash key values are different, and the fact that the frames of the same data stream can be forwarded on the same physical link is achieved. However, although the stream-by-stream load sharing method can guarantee the sequential transmission of packets, it cannot guarantee the bandwidth utilization rate. Therefore, how to provide a more effective link aggregation method becomes a technical problem to be solved urgently.

Based on this, embodiments of the present application provide a link aggregation method, a link aggregation apparatus, an electronic device, and a storage medium, which can effectively improve the efficiency of link aggregation.

The link aggregation method provided by the embodiment of the application can be applied to a terminal, a server side and software running in the terminal or the server side. In some embodiments, the terminal may be a smartphone, tablet, laptop, desktop computer, or the like; the server side can be configured as an independent physical server, or a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as cloud service, a cloud database, cloud computing, cloud functions, cloud storage, Network service, cloud communication, middleware service, domain name service, security service, Content Delivery Network (CDN) and a big data and artificial intelligence platform; the software may be an application or the like implementing the link aggregation method of the present application, but is not limited to the above form.

The application is operational with numerous general purpose or special purpose computing system environments or configurations. For example: personal computers, server computers, hand-held or portable devices, tablet-type devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like. The application may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The application may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.

Referring to fig. 1, fig. 1 is an optional flowchart of a link aggregation method provided in an embodiment of the present application, where the method is applied to a client, and the method in fig. 1 may specifically include, but is not limited to, step S110 to step S160.

Step S110, obtaining configuration demand information of a local user side of a client, and configuring a corresponding link aggregation group, a channel port in the link aggregation group and an aggregation group priority of the link aggregation group according to the configuration demand information, wherein the client is in communication connection with at least one local user side of the client;

step S120, sending link aggregation control request information to the server according to the configuration requirement information, and receiving reply information sent by the server according to the link aggregation control request information;

step S130, establishing a service control channel of each link aggregation group and the service end according to the reply information, and identifying all channel ports in each link aggregation group as the same aggregation transmission control connection information;

step S140, obtaining a first data packet received by a local user side of a client, and caching the first data packet to an aggregation sending buffer area of a corresponding link aggregation group according to a preset configuration strategy;

step S150, the data of the aggregation sending buffer area is sent to a corresponding server side through a service control channel;

step S160, reading the first processed data sent by the server according to the first data packet through the aggregation receiving buffer of the link aggregation group, and forwarding the first processed data to the corresponding local user side of the client according to the opposite end sending order.

In step S110 of some embodiments, because the service transmission bandwidth and the transmission real-time requirement of each service corresponding to the client local user side are different, first, configuration requirement information of the client local user side is obtained, specifically, the configuration requirement information includes service transmission bandwidth information, transmission real-time information, an IP address and a port number of the client, and configures an aggregation group priority of a corresponding link aggregation group, a channel port in the link aggregation group, and a link aggregation group according to the configuration requirement information, where the client is in communication connection with at least one client local user side.

It should be noted that, when configuring the local user side of the client, the link aggregation group may also be configured by default to forward all the service ports that are not configured and the corresponding priorities.

It should be noted that the client provides multiple user interfaces to connect with at least one client local user side, and the accessed client local user side may be in one network segment or multiple network segments. Meanwhile, the client provides a plurality of channel interfaces to establish a channel connection, wherein the client may connect a single channel or a plurality of channels, and the channel transmission delay and the channel transmission bandwidth of the connection may differ greatly, which is not limited herein.

It should be noted that, when the client is connected to only one client local user side, the channel port of the client local user side is directly connected to the user port of the client. In addition, when the client is connected with a plurality of client local user sides and the plurality of client local user sides are distributed in the same network segment, the user port of the client is connected through a switch interface of the client local user side; when the client is connected with a plurality of client local user sides and the plurality of client local user sides are distributed in a plurality of network segments, the client local user sides are respectively connected with gateway interfaces of the plurality of network segments so as to be connected with user ports of the client. And after the connection is completed, configuring an IP address range corresponding to each user port at the client.

It should be noted that, when the channel connected to the client is abnormal, that is, the channel is disconnected, the client can automatically aggregate the remaining available channels in the link aggregation group to continue to provide data interaction operations.

In step S120 of some embodiments, in order to implement link aggregation between the client and the server, link aggregation control request information is sent to the server according to the configuration requirement information, and reply information sent by the server according to the link aggregation control request information is received, so as to complete TCP link establishment interaction between the client and the server in the signaling control plane. Specifically, the client sends link aggregation control request information to a signaling control port of the server according to the configuration requirement information, that is, sends a standard TCP connection, where a source IP address of the TCP connection is a channel port address of the client that is sent, and a destination IP address of the TCP connection is a channel port address of the server that is received. It should be noted that the client may also send TCP connections to all the servers at each channel port to establish a plurality of channel connections respectively to detect the current on-off state of the channel.

It should be noted that, when the link aggregation control request message sent by the client to the server fails to be connected, that is, the client does not receive the reply message returned by the server, the client performs round-robin sending at a preset sending period through different channel ports to complete TCP link establishment interaction at the signaling control layer between the client and the server.

In step S130 of some embodiments, when receiving a reply message sent by the server according to the link aggregation control request message, a service control channel between each link aggregation group and the server is established according to the reply message, and in order to improve the efficiency of link aggregation, all channel ports in each link aggregation group are identified as the same aggregation transmission control connection message. Specifically, when receiving reply information sent by the server according to the link aggregation control request information, the client sends an aggregated TCP connection to the server according to the reply information to establish a service control channel with the server for each link aggregation group. The source IP address in the aggregated TCP packet corresponding to the aggregated TCP connection is the IP address of the sending channel port, and all the channel ports in each link aggregation group are identified as the same aggregated transmission control connection information, that is, the IP addresses of all the channel ports of the client, the IP addresses of the server, and the corresponding ports in the same link aggregation group are identified as the same aggregated transmission control connection information. For example, a channel port and an IP address of the client, an IP address of the server, and a corresponding port of the server are combined into a quadruple, and for example, the quadruple formed by the three channel ports IPa, IPb, and IPc corresponding to the client is: the same aggregated transmission control connection information is identified for both the client and the server (client channel IPa, server IP, client port a, server port B), (client channel IPb, server IP, client port a, server port B), and (client channel IPc, server IP, client port a, server port B), i.e. the same aggregated TCP connection.

It should be noted that the client and the server may perform an interactive operation through the same aggregated TCP connection, and a destination IP address responded by the server may be an IP address of any reachable channel port in the client link aggregation group.

It should be noted that the client and the server may also perform data transceiving, packet loss retransmission, and out-of-order queuing processing through the same aggregated TCP connection, and meanwhile, when multiple aggregated TCP connections are processed, perform protocol processing according to the priority corresponding to the aggregated TCP connections.

It should be noted that, when receiving the link aggregation control request information sent by the client, the server detects whether resources such as the remaining memory of the current server are satisfied with responding to the link aggregation control request information, and when the resources such as the remaining memory are satisfied with responding to the link aggregation control request information, the server sends the reply information to the client according to the link aggregation control request information.

In step S140 of some embodiments, the client obtains the first data packet received by the local user side of the client, and caches the first data packet to the aggregation sending buffer of the corresponding link aggregation group according to a preset configuration policy. Specifically, the client receives a first data packet from the user port at the local user side of the client, performs data caching according to a preset configuration policy, that is, according to the configured link aggregation group, the channel port in the link aggregation group, and the aggregation group priority of the link aggregation group, and caches the first data packet to the aggregation TCP sending queue of the aggregation sending buffer of the corresponding link aggregation group.

In step S150 of some embodiments, in order to improve the efficiency of link aggregation, the client transmits the data of the aggregated transmission buffer to the corresponding server through the traffic control channel. Specifically, the client and the server perform data transceiving, packet loss retransmission, and out-of-order queuing processing of the same aggregated TCP connection through multiple channels, and may perform protocol processing on multiple aggregated TCP connections according to priority.

In step S160 of some embodiments, in order to ensure the ordered reception of the data packets, so as to improve the efficiency of link aggregation, the client reads the first processing data sent by the server according to the first data packet through the aggregation receiving buffer of the link aggregation group, and forwards the first processing data to the corresponding client local user side according to the peer-to-peer sending order. Specifically, the client or the server reads first processing data sent by the server according to the first data packet from an aggregation receiving buffer of the link aggregation group, that is, through an aggregation TCP connection, and forwards the first processing data to users at respective local user sides according to an opposite-end sending order.

Referring to fig. 2, fig. 2 is a flowchart illustrating a specific method of step S110 according to some embodiments of the present disclosure. In some embodiments of the present application, the client includes at least one channel port, and step S110 specifically includes, but is not limited to, step S210 to step S240, which are described in detail below with reference to fig. 2.

step S220, after the channel connection is successful, port parameter information is configured for the channel port through the client, and the port parameter information is used for controlling data transmission between the local user side of the client and the client;

step S230, acquiring configuration demand information of a local user side of the client;

step S240, configuring the corresponding link aggregation group, the channel port in the link aggregation group, and the aggregation group priority of the link aggregation group according to the configuration requirement information.

In steps S210 and S220 of some embodiments, before performing link aggregation between the client and the server, a channel connection between the client and the local user side of the client is established through a channel port of the client, and after the channel connection is successful, port parameter information is configured for the channel port through the client, where the port parameter information is used to control data transmission between the local user side of the client and the client. Specifically, each channel is directly connected to a channel port of the client, and after the channel connection is successful, port parameter information of each channel port is configured at the client, where the port parameter information includes an IP address and an IP address of a connected gateway, and the port parameter information is used to control data transmission between the local user side of the client and the client. Meanwhile, under the condition that the channel parameters are configured, the transmission bandwidth and the transmission time delay of the connected channel are configured at the client.

It should be noted that, after the channel connection is successful, the IP address of the port of the server-side connection router and the IP address of the connected router are configured at the same time.

In step S230 and step S240 of some embodiments, in order to implement that a channel with a larger delay difference can also perform link aggregation, configuration requirement information of a local user side of a client is obtained, and a corresponding link aggregation group, a channel port in the link aggregation group, and an aggregation group priority of the link aggregation group are configured according to the configuration requirement information. The configuration requirement information is the same as the content in the above embodiments, and is not described herein again.

It should be noted that, when a local user side of a client of the client communicates with an opposite-end user, an IP address range of the opposite-end user and an IP address of a server corresponding to the opposite-end user are configured at the client according to the communication relationship, and an IP address of the server may also be configured by default to forward all the opposite-end users that are not configured.

Referring to fig. 3, fig. 3 is a flowchart illustrating a specific method of step S120 according to some embodiments of the present disclosure. In some embodiments of the present application, step S120 further includes, but is not limited to, step S310 to step S340, which are described in detail below with reference to fig. 3.

Step S310, sending standard transmission control connection request information to a server;

step S320, receiving response information sent by the server according to the standard transmission control connection request information, and establishing transmission control communication connection between the client and the server according to the response information;

step S330, sending the link aggregation control request information of each link aggregation group to the server according to the transmission control communication connection;

step S340, receiving a reply message sent by the server according to the link aggregation control request message, and storing the port access information of the server corresponding to each link aggregation group according to the reply message record.

In step S310 of some embodiments, to implement link aggregation between the client and the server, the client sends standard TCP connection, which is standard TCP connection, to a signaling control port of the server.

In steps S320 and S330 of some embodiments, the client receives response information sent by the server according to the standard transmission control connection request information, establishes a transmission control communication connection between the client and the server according to the response information, and sends link aggregation control request information of each link aggregation group to the server according to the transmission control communication connection. It should be noted that, the client sends link aggregation control request information to the server for each link aggregation group in a standard TCP connection, and the link aggregation control request information includes the transmission priority of the link aggregation group, the IP address of each channel port in the link aggregation group, the IP address range of the client access user, and the like.

In step S340 of some embodiments, the client receives reply information sent by the server according to the link aggregation control request information, and stores port access information of the server corresponding to each link aggregation group according to the reply information record. Specifically, after receiving the link aggregation control request information of each link aggregation group sent by the client, the server starts the service port corresponding to the server to monitor, sets the processing priority of the service port, records the IP address of each channel port of the client and the IP address range of the client user in the link aggregation group, and sends reply information to the client according to the link aggregation control request information, wherein it needs to be stated that the reply information is attached with the service port of the server and the IP address range of the service access user. Therefore, after receiving the reply message, the client records and stores the port access information of the corresponding server of each link aggregation group, wherein the port access information comprises the service port of the server and the IP address range of the access user of the server.

step S450, buffer the second data packet to the aggregation sending buffer of the aggregation transmission control connection.

In steps S410 to S450 of some embodiments, the client receives an ethernet packet at the local user side of the client from the user port, performs type determination on the ethernet packet, and when the ethernet packet satisfies a preset packet type, the preset packet type is UDP, that is, when the ethernet packet is a UDP packet, the obtained ethernet packet is a first packet. And recording the network address corresponding relation in the first data packet into a record table of the client, specifically, recording the corresponding relation between the IP address and the MAC address in the first data packet into the record table, namely, refreshing the corresponding relation between the IP address and the MAC address. And then, removing the header of the first data packet, namely deleting the Ethernet frame header of the first data packet to obtain a second data packet, namely the second data packet comprises the IP header data and the subsequent field data corresponding to the first data packet, and caching the obtained second data packet into an aggregation transmission buffer connected with aggregation transmission control. According to the embodiment of the application, the data cached in the aggregation sending buffer area is processed in advance, so that the link aggregation efficiency is improved.

It should be noted that, when the ethernet packet does not satisfy the predetermined packet type, for example, the predetermined packet type is UDP, that is, when the ethernet packet is not a UDP packet, the ethernet packet may be processed according to the existing packet-by-packet and/or stream-by-stream link aggregation manner.

Referring to fig. 5, fig. 5 is a flowchart illustrating a specific method of step S150 according to some embodiments of the present disclosure. In some embodiments of the present application, step S150 specifically includes, but is not limited to, step S510 and step S520, which are described in detail below with reference to fig. 5.

Step S510, performing data packaging processing on the data of the aggregation sending buffer area to obtain a third data packet;

step S520, the third data packet is sent to the corresponding server through the service control channel.

In step S510 and step S520 of some embodiments, in order to ensure the ordered reception of the data packet and improve the bandwidth utilization rate during link aggregation, when the client sends the data in the aggregated sending buffer to the corresponding server through the service control channel, the client performs data packing processing on the data in the aggregated sending buffer to obtain a third data packet. Specifically, the client performs data packing processing on data in a sending buffer of the link aggregation group, specifically, adds the data into a packet divider, a packet length and a check to obtain a third data packet, and sends the third data packet to the server through a service control channel.

It should be noted that, when the length of a data stream of a third data packet sent by a client exceeds the maximum transmission unit MTU, the data of the third data packet is divided into multiple packets to be sent, and a data format and an interaction flow of a TCP protocol stack are used, when it is determined that a certain channel port of a link aggregation group is used to send a data packet, an IP address corresponding to the channel port is filled into a source IP of the data packet, where an IP address of the channel port in the link aggregation group and a corresponding port both identify a unique aggregated TCP connection in the link aggregation group, and specifically, which channel port can be processed in a packet-by-packet manner, residual bandwidth calculation manner, and the like is not described herein again.

It should be noted that, after receiving the data stream corresponding to the third data packet, the server queries the MAC address corresponding to the destination IP address of the data packet, and when the head sending sequence number of the third data packet is inconsistent with the currently expected sequence number, the server obtains a query result, and buffers the data packet in the receiving buffer of the link aggregation group, that is, inserts the data packet into the user side output queue, and sends an ARP protocol query and sends an acknowledgement response message to the client. After acquiring the corresponding relation between the IP address and the MAC address, sequentially adding an Ethernet frame header to the data packet of the user side output queue, and outputting the Ethernet packet through a user port.

It should be noted that, the client or the server receives the ethernet data packet sent from the user to the opposite-end user through the transparent mode or the gateway mode, and is configured to output the user IP address and the MAC address association record to the IP-MAC table, and intercept part of data in the ethernet data packet to output for the link aggregation service.

It should be noted that, after the server receives the data stream corresponding to the third data packet, when the head sending sequence number of the third data packet is consistent with the currently expected sequence number, the data in the receiving buffer corresponding to the aggregated TCP connection is copied to the receiving buffer of the server user. And when the packet segmentation symbol, the packet length and the check in the receiving cache of the service end user pass, acquiring the complete UDP message. And then, the server side directly forwards the complete UDP message obtained after the processing is finished to the destination IP address identified by the message. When it needs to be described, after the client receives the data packet sent by the server, the processing method is the same as that after the server receives the data packet, and is not described herein again.

It should be noted that, when the client has multiple link aggregation groups at the same time, the client sequentially processes according to the priority of each link aggregation group, but each link aggregation group needs to ensure that timeout events such as retransmission cannot be generated, so as to ensure the ordered reception of data packets, and improve the efficiency of link aggregation.

It should be noted that, the client or the server may configure different users and different service transceiving priorities of the same user, so as to preferentially process a user or a service with a high priority, thereby improving the efficiency of link aggregation.

In some embodiments of the present application, after step S520, the link aggregation method provided in the embodiments of the present application further includes: and when the client does not receive the confirmation response information of the server according to the third data packet within the preset response time threshold, sending the third data packet to the corresponding server through the service control channel again.

In some specific embodiments, the preset response time threshold may be set to be at least 3 times of the link transmission delay, and when the client does not receive the acknowledgement response information of the server according to the third data packet within the preset response time threshold, the unacknowledged third data packet is sent to the corresponding server through the service control channel again, so as to improve the bandwidth utilization rate during link aggregation.

It should be noted that, when the server sends a data stream to the client, it specifically uses which channel port in the link aggregation group sends the data stream to fill the IP address of the port into the destination IP of the packet, and the specifically used channel port may be processed in a packet-by-packet manner, a residual bandwidth calculation manner, and the like.

Referring to fig. 6, fig. 6 is another alternative flowchart of a link aggregation method provided in the present application, where the method is applied to a server.

And then, the server side sends the data of the aggregation sending buffer area to the corresponding client side through the service control channel, reads second processing data sent by the client side according to the fourth data packet through the aggregation receiving buffer area of the link aggregation group, and forwards the second processing data to the corresponding local user side of the server side according to the sending sequence of the opposite end. The embodiment of the application provides a method for performing link aggregation based on a plurality of channels with large transmission delay difference, which can ensure the ordered reception of data packets and improve the bandwidth utilization rate during link aggregation.

It should be noted that the server provides multiple user interfaces to connect to multiple local user sides of the server, that is, a single user or multiple users can be accessed, and the accessed user can be in one network segment or multiple network segments, and meanwhile, the server provides an aggregation interface to connect to a router or a gateway.
