Description

Link aggregation method, link aggregation device, electronic equipment and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a link aggregation method, a link aggregation device, an electronic device, and a storage medium.

Background

In order to fully utilize the bandwidths of multiple physical links aggregated together to achieve orderly and reliable transmission of standard user datagram protocol (User Datagram Protocol, UDP) messages, a link aggregation method is generally adopted to achieve scheduling and traffic allocation on the multiple physical links. The existing method for realizing link aggregation comprises the following steps: (1) packet-by-packet load sharing: by having a first data frame of the data stream transmitted over a physical link; and a second data frame is transmitted over the other physical link. The method makes it possible for the second data frame of the same data stream to arrive at the opposite device earlier than the first data frame, thereby creating a case where the received data packets are out of order. (2) per-stream load sharing: the addresses in the data frames are generated into Hash key values through a Hash algorithm, and then corresponding outgoing interfaces are searched in a forwarding table according to the key values. However, the use of this stream-by-stream load sharing method, while guaranteeing sequential transmission of packets, cannot guarantee its bandwidth utilization. Therefore, how to provide a more efficient link aggregation method is a technical problem to be solved.

Referring to fig. 1, fig. 1 is an optional flowchart of a link aggregation method according to 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, steps S110 to S160.

Step S110, obtaining configuration requirement 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 requirement 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 a server according to 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 a service end according to the reply information, and marking all channel ports in each link aggregation group as same aggregation transmission control connection information;

Step S140, a first data packet received by a local user side of a client is obtained, and the first data packet is cached to an aggregation transmitting buffer area of a corresponding link aggregation group according to a preset configuration strategy;

Step S150, data of the aggregation transmission buffer area is transmitted to a corresponding server through a service control channel;

Step S160, the service end reads the first processing data sent by the first data packet through the aggregation receiving buffer area of the link aggregation group, and forwards the first processing data to the corresponding local user side of the client according to the sending order of the opposite end.

In step S110 of some embodiments, due to the difference between the service transmission bandwidth and the transmission real-time requirement of each service corresponding to the local user side of the client, configuration requirement information of the local user side of the client is first obtained, where the configuration requirement information includes service transmission bandwidth information, transmission real-time information, an IP address and a port number of the client, and the like, 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, where the client is communicatively connected to at least one local user side of the client.

It should be noted that, when configuring the local user side of the client, the link aggregation group may be configured by default to forward all the unconfigured service ports and the corresponding priorities.

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

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 switch interface of the client local user sides is connected with the user port of the client; when the client is connected with a plurality of client local user sides and the plurality of client local user sides are distributed on a plurality of network segments, gateway interfaces of the plurality of network segments are respectively connected to connect user ports of the client. 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 by the client is abnormal, that is, the channel connection is not enabled, the client can automatically aggregate the remaining available channels in the link aggregation group to continue to provide data interaction operation.

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

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

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

It should be noted that, the client and the server may perform an interactive operation through the same aggregated TCP connection, and the destination IP address responded by the server may be any reachable channel port IP address 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 at the same time, when a plurality of aggregated TCP connections perform processing, perform protocol processing according to priorities corresponding to the aggregated TCP connections.

It should be noted that, when the server receives the link aggregation control request information sent by the client, it detects whether the current resources such as the remaining memory of the server meet the response to the link aggregation control request information, and when the resources such as the remaining memory meet the response to the link aggregation control request information, the server sends reply information to the client according to the link aggregation control request information.

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

In step S150 of some embodiments, in order to improve the efficiency of link aggregation, the client sends the data of the aggregate sending buffer to the corresponding server through the service control channel. Specifically, the client and the server perform data transceiving, packet loss retransmission and out-of-order queuing processing on the same aggregated TCP connection through a plurality of channels, and the aggregated TCP connections can be subjected to protocol processing according to priority.

In step S160 of some embodiments, in order to ensure orderly reception of the data packets, so as to improve the link aggregation efficiency, 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 local client side according to the sending order of the opposite ends. Specifically, the client or the server reads the first processing data sent by the server according to the first data packet through the aggregated TCP connection from the aggregated receiving buffer of the link aggregation group, and forwards the first processing data to the users of the local user sides according to the sending order of the opposite ends.

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

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

step S230, obtaining configuration requirement information of a local user side of a client;

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

In step S210 and step S220 of some embodiments, before link aggregation between the client and the server is performed, a channel connection between the client and the client local user side 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 client local user side 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, wherein the port parameter information comprises an IP address and an IP address of a connected gateway, and the port parameter information is used for controlling data transmission between a local user side of the client and the client. Meanwhile, under the condition that channel parameters are configured, the connected channel transmission bandwidth and transmission delay are configured at the client.

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

In step S230 and step S240 of some embodiments, in order to implement link aggregation of channels with larger delay differences, configuration requirement information of a local user side of a client is obtained, and a corresponding link aggregation group, channel ports 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 that in the above embodiment, and will not be described here again.

When a local user side of a client and an opposite user of the client communicate, the IP address range of the opposite user and the IP address of the service end corresponding to the opposite user are configured in the client according to the communication relationship, and the IP address of the service end may be configured by default to forward all the unconfigured opposite users.

Referring to fig. 3, fig. 3 is a flowchart illustrating a specific method of step S120 according to some embodiments of the present application. In some embodiments of the present application, step S120 specifically includes, but is not limited to, steps S310 to S340, and these four steps are described in detail below in conjunction with 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, the link aggregation control request information of each link aggregation group is sent to the server according to the transmission control communication connection;

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

In step S310 of some embodiments, in order to implement link aggregation between the client and the server, the client sends standard transmission control connection request information, i.e. a standard TCP connection, to a signaling control port of the server.

In step S320 and step 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, in the standard TCP connection, the client sends link aggregation control request information to the server for each link aggregation group, and the link aggregation control request information is accompanied by a transmission priority of the link aggregation group, an IP address of each channel port in the link aggregation group, an IP address range of the client access user, and the like.

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

Referring to fig. 4, fig. 4 is a flowchart illustrating a specific method of step S140 according to some embodiments of the present application. In some embodiments of the present application, step S140 includes, but is not limited to, steps S410 to S450, and these five steps are described in detail below in conjunction with fig. 4.

Step S440, removing the packet header of the first data packet to obtain a second data packet;

in step S450, the second data packet is buffered in an aggregate transmit buffer of the aggregate transmission control connection.

In steps S410 to S450 of some embodiments, the client receives an ethernet packet of the local user side of the client from the user port, performs type judgment on the ethernet packet, and when the ethernet packet meets 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. The corresponding relation of the network address in the first data packet is recorded in a record table of the client, specifically, the corresponding relation of the IP address and the MAC address in the first data packet is recorded in the record table, namely, the corresponding relation of the IP address and the MAC address is refreshed. And then, removing the packet 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 IP header data and subsequent field data corresponding to the first data packet, and caching the obtained second data packet in an aggregation transmitting buffer area of aggregation transmission control connection. The embodiment of the application improves the efficiency of link aggregation by processing the data cached in the aggregation sending buffer area in advance.

It should be noted that, when the ethernet packet does not satisfy the preset packet type, for example, the preset 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 application. In some embodiments of the present application, step S150 includes, but is not limited to, step S510 and step S520, which are described in detail below in conjunction with fig. 5.

Step S510, data in the aggregation transmission buffer area is subjected to data packaging processing to obtain a third data packet;

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

In step S510 and step S520 of some embodiments, in order to ensure orderly reception of the data packet and improve the bandwidth utilization rate during link aggregation, when the client sends the data in the aggregate sending buffer to the corresponding server through the service control channel, the data in the aggregate sending buffer is subjected to data packaging processing, so as to obtain a third data packet. Specifically, the client performs data packaging processing on the data in the transmission buffer area of the link aggregation group, specifically, adds the data into the packet separator, the packet length and the verification to obtain a third data packet, and sends the third data packet to the server through the service control channel.

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

After receiving the data stream corresponding to the third data packet, the server side 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, that is, the query result is obtained, the data packet is cached in the receiving buffer area of the link aggregation group, that is, the data packet is inserted into the output queue of the user side, and ARP query is sent and acknowledgement response information is sent to the client side. After the corresponding relation between the IP address and the MAC address is obtained, the data packets of the output queue of the user side are sequentially added with the Ethernet frame header, and then the Ethernet packets are output through the user port.

It should be noted that, the client or the server receives the ethernet packet sent from the user to the user at the opposite end through the transparent mode or the gateway mode, and is used for outputting the IP address and the MAC address of the user, associating and recording the IP address and the MAC address to the IP-MAC table, and intercepting part of the data output in the ethernet packet for performing 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 current expected sequence number, the data in the receiving buffer area corresponding to the aggregate TCP connection is copied to the receiving buffer area of the user at the server. And when the packet separator, the packet length and the verification in the buffer memory are received by the service end user, acquiring a complete UDP message. And then, the server directly forwards the complete UDP message obtained after the processing is completed to a 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 manner of the data packet is the same as that of the data packet sent by the server, and will not be described herein.

It should be noted that, when the client side has multiple link aggregation groups at the same time, the client side processes the link aggregation groups in sequence 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, thereby ensuring orderly reception of the data packets so as to 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 to preferentially process the users or services with high priority, thereby improving the efficiency of link aggregation.

In some embodiments of the present application, after step S520, the link aggregation method provided by the embodiment of the present application further includes: and when the client side does not receive the confirmation response information of the third data packet according to the third data packet within the preset response time threshold, the third data packet is sent to the corresponding server side 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 link transmission delay, when the client side does not receive the acknowledgement response information of the third data packet according to the third data packet within the preset response time threshold, the unacknowledged third data packet is sent to the corresponding server side through the service control channel again, so that the bandwidth utilization rate during link aggregation is improved.

When the server sends a data stream to the client, the server specifically adopts which channel port in the link aggregation group is sent to fill the IP address of the port into the destination IP of the message, and the specifically adopted channel port can be processed in a packet-by-packet manner, a residual bandwidth calculation manner, and the like, which can refer to the link aggregation method from the client to the server, and will not be described herein.

Referring to fig. 6, fig. 6 is another alternative flowchart of a link aggregation method according to an embodiment of the present application, where the method is applied to a server. In some embodiments of the present application, the method specifically includes, but is not limited to, steps S610 to S680, which are described in detail below in conjunction with fig. 6.

step S640, sending reply information according to the link aggregation control request information to the client through the server;

Step S650, establishing a service control channel with the client through each link aggregation group, and marking all channel ports in each link aggregation group as same aggregation transmission control connection information;

Step S660, a fourth data packet received by a local user side of the server is obtained, and the fourth data packet is cached to an aggregation transmitting buffer zone of a link aggregation group according to a preset configuration strategy, wherein the server is in communication connection with at least one local user side of the server;

Step S670, data of the aggregation transmission buffer area is transmitted to a corresponding client through a service control channel;

in step S680, the second processing data sent by the client according to the fourth data packet is read through the aggregation receiving buffer of the link aggregation group, and the second processing data is forwarded to the corresponding local user side of the server according to the sending order of the opposite end.

In steps S610 to S680 of some embodiments, the server receives the standard transmission control connection request information sent by the client, and sends response information to the client according to the standard transmission control connection request information, so as to establish a transmission control communication connection between the client and the server. After the transmission control communication connection is created, the server receives the link aggregation control request information of each link aggregation group sent by the client according to the configuration requirement information, and obtains the link aggregation group corresponding to the link aggregation control request information, the channel port in the link aggregation group and the aggregation group priority of the link aggregation group, wherein the configuration requirement information, the link aggregation group, the channel port and the aggregation group priority are obtained according to the method of the above embodiment. And the server side establishes a service control channel with the client side through each link aggregation group and marks all channel ports in each link aggregation group as the same aggregation transmission control connection information.

And then, the server transmits the data of the aggregation transmitting buffer area to the corresponding client through the service control channel, reads the second processing data transmitted by the client 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 according to the transmitting order of the opposite terminal. The embodiment of the application provides a method for link aggregation based on a plurality of channels with larger transmission delay differences, which can ensure the ordered receiving of data packets and improve the bandwidth utilization rate during link aggregation.

It should be noted that, the server side provides multiple user interfaces to connect to local user sides of multiple server sides, i.e. a single or multiple users can be accessed, and the accessed users can be in one network segment or multiple network segments, and at the same time, the server side provides an aggregate interface to connect to a router or gateway.

It should be noted that, the server may provide the link aggregation service to a single or multiple clients at the same time.

It should be noted that, the user to which the client and the server are respectively connected may send and receive UDP messages in both directions, and may be delivered to the user of the opposite terminal according to the sending sequence after link aggregation, and may be retransmitted automatically when the packet is lost, so as to improve the efficiency of link aggregation.
