In such a high-performance, high-availability, high-reliability base cloud network chassis, the temporary packets are typically stored in a data buffer of the physical switch, where the data buffer is divided into a receive buffer, a transmit buffer, and a Headroom buffer. According to different functional effects, the receiving buffer is used for buffering received data, the transmitting buffer is used for buffering transmitted data, and the Headroom buffer provides additional message buffering capacity for the device after the space of the two data buffers is used up. At present, in the process of receiving or sending a message, an OVS and a physical switch of a cloud platform store the message into a buffer area, and once the buffer area is full, the buffered message is discarded, and for important traffic, although the QOS is used for setting a DSCP value of the traffic to forward the traffic preferentially, so that the traffic with a high DSCP value enters the buffer preferentially, but the buffer area is discarded after being full; in addition, the traditional cloud platform does not uniformly analyze and display the traffic packet loss condition of the underly and overlay devices, and when the OVS or the switch is full due to the buffer area, the application of reconnection can be autonomously sent after the TCP connection of the client is disconnected due to packet loss, and the buffer area is full, so that the continuous packet loss and continuous reconnection vicious cycle can be caused.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, in one embodiment, a cloud network traffic forwarding method includes the following steps:
in step S110, a transmission path of a first traffic is confirmed, where the first traffic is a traffic with a transmission priority higher than a first threshold.
Specifically, the user classifies the traffic according to the importance degree of the traffic, wherein the first traffic is of a traffic type needing lossless forwarding, so that the transmission priority of the first traffic is set to be higher than a first threshold. For example, the user considers that the flow of accessing the object storage and the file storage by the virtual machine is important, and the flow can be set to be the first flow, so that the possibility of packet loss is reduced to the greatest extent in the transmission process. And finding out a transmission path of the service flow according to the flow type set by the user, and further finding out a starting point in the transmission path and switch equipment of each node. Wherein the switch device comprises an OVS (virtual switch) and a physical switch.
It should be noted that, when the transmission path transmits and receives the first traffic and other traffic types, only the other traffic types remain in the path after the transmission of the first traffic in the transmission path is completed.
Step S120, adjusting the buffer capacity of the switch device in the transmission path to a second threshold value, wherein the second threshold value is not smaller than the current value of the buffer capacity of the switch device.
Specifically, the starting point of the transmission path where the first flow is located and the buffer capacity of each switch device of each node are adjusted to a second threshold, that is, the buffer capacity of the switch device is increased, so as to avoid packet loss of the first flow. Generally, the buffer capacity of each switch device in the transmission path for transmitting the first traffic can be adjusted to the maximum value, so as to ensure the stability and smoothness of the transmission process of the first traffic as much as possible.
Step S130, monitoring the buffer queue and buffer ratio of the switch device in the transmission path, and when the buffer ratio is greater than a third threshold, preferentially transmitting a first flow in the buffer queue, and reducing a second flow entering the buffer queue, wherein the second flow is a flow with a transmission priority lower than the first threshold.
Specifically, the transmission path is monitored, when the buffer ratio of the buffer queue where the first flow is located exceeds a third threshold, the risk of congestion packet loss occurring in the buffer queue is considered to be larger, and the DSCP (differential service code point) values of the outer layer Vxlan (extensible virtual local area network) head and the inner layer IP packet head of the first flow in the buffer queue are set to be the highest, so that the first flow can enter the buffer queue preferentially, the number of packets sent by the buffer queue is reduced, the second flow entering the buffer queue is reduced, and the buffer ratio in the buffer queue is reduced. The transmission priority of the second flow is lower than that of the first flow, and lossless forwarding is not needed; the buffer ratio is the ratio of the buffer capacity of the exchanger equipment occupied by all traffic in the path.
It should be noted that, the third threshold of the buffer ratio may be set by the user according to the importance degree of the traffic, for example, the third threshold may be set to 80%, and if more important traffic is transmitted, the ratio may be reduced, so as to reduce the packet loss risk of the first traffic.
Step S140, the packet loss flow in the transmission path is obtained, and the message content corresponding to the packet loss flow is sent.
Specifically, packet loss generally refers to that traffic data cannot be transmitted to a destination for various reasons, which easily causes data loss and even causes packet loss of other related traffic data. When the situation of the buffer packet loss of the exchanger equipment in the transmission path is obtained, and the condition that the flow packet loss occurs to a certain exchanger equipment is monitored, the lost message content of the exchanger equipment is grabbed, and the lost message content is displayed to a user. The user can improve the priority of the packet loss flow based on the displayed content, and change the type of the packet loss flow into the first flow so as to reduce the possibility of packet loss of the flow, and also improve the buffer capacity of the exchanger equipment in the flow transmission path. Through a man-machine interaction way, a user can autonomously determine the priority of flow forwarding, and the lossless forwarding of important flows is ensured.
According to the cloud network flow forwarding method, according to the flow type set by a user, the buffer capacity of the switch equipment in the first flow transmission path is adjusted to the second threshold value, lossless forwarding of the first flow is primarily guaranteed, the first flow in the buffer queue with the buffer proportion higher than the third threshold value is preferentially sent in the transmission process, the number of messages sent by the queue is reduced, the second flow entering the buffer queue is reduced, the buffer proportion in the queue is reduced, and the lost message content in the transmission process is captured and then displayed to the user. The method determines the priority of flow forwarding by the user, thereby ensuring the lossless forwarding of important flows, analyzing the discarded flows due to the full buffer area in the transmission process and displaying the discarded flows to the user, and deepening the knowledge of the user on the network flow discarding condition, so that the user can make further planning on the flow types and the buffer capacity according to the displaying content.
As shown in fig. 2, in this embodiment, the method further includes the following steps before confirming the transmission path of the first traffic:
step S210, a sys-agent program is set at each switch device, and the sys-agent program is used for collecting statistical data and storing the statistical data into the ES node, wherein the statistical data comprises buffer capacity, buffer proportion, packet loss condition and discarded message content.
Specifically, sys-agent programs are deployed at a plurality of nodes such as a computing node, a network element node, an underway switch node and the like, so that relevant statistical data are obtained from the OVS, the DPOS and the underway switch, and the data are stored in the ES node. The statistical data comprises network cards, VPC, CPU, subnet, bps and pps of messages with connection number grades, delay and packet loss statistics, discarded message content and data of netprobes (network real-time monitoring tool) and DTCs.
And step S220, carrying out a vnet-controller program, wherein the vnet-controller program is used for acquiring statistical data from the ES node and displaying the statistical data to a user through a Kafka system.
Specifically, the Kafka system is a high-throughput distributed publish-subscribe messaging system capable of processing all action flow data of users in websites.
As shown in fig. 3, in this embodiment, the packet loss flow in the transmission path is obtained, and the message content corresponding to the packet loss flow is sent, which specifically includes the following steps:
step S141, the exchanger equipment is monitored, the buffer packet loss condition of each exchanger equipment is obtained through a sys-agent program, and when the condition that the flow packet loss occurs in a certain exchanger equipment is monitored, the content of the lost message is obtained and stored in an ES node.
Specifically, each port of the OVS and the physical switch in the transmission path is monitored, the buffer packet loss condition of each port is obtained through a sys-agent program, when a certain device port is detected to have traffic packet loss, the content of a message transmitted by the device is grabbed through the sys-agent program to obtain the content of the lost message, and the content of the lost message is stored in the ES node.
And step S142, acquiring the content of the lost message in the ES node through a vnet-controller program and sending the content to a user so that the user can adjust according to the importance degree of the packet loss flow.
Specifically, the vnet-controller program can automatically detect statistical data in the ES node, and when packet loss information is detected, the content of the lost message in the ES node is read and displayed to a user through the Kafka system. Based on the content displayed by the operation and maintenance system, the user can convert the packet loss flow into the first flow so as to reduce the possibility of packet loss of the flow and improve the buffer capacity of the switch equipment in the flow transmission path. For example, if the lost message is a new connection message of TCP (transmission control protocol) or a reconnection message of TCP, which indicates that the service of the TCP has been affected, the user should elastically expand the service of the back end of the TCP or increase the priority of the service traffic according to the content shown, and convert the service into the first traffic.
In this embodiment, the first traffic is traffic that needs to be retransmitted with a large amount of data after the packet loss occurs, so that bandwidth is wasted, or the data is lost after the packet loss.
In this embodiment, the user may differentiate risk levels in the buffer queues with different buffer ratios according to the importance level of the traffic in the transmission path, for example, consider a queue with a buffer ratio exceeding 80% as a cache queue, where the risk of packet loss of the queue is higher. When the buffer ratio of the queue is reduced to 50%, the packet loss risk of the queue is reduced to a general risk, and the transmitting end of the first flow in the queue can be released at the moment so as to enable the first flow in the queue to be forwarded normally; when the buffer ratio in the buffer queue is reduced to 30%, the packet loss risk of the queue is low, and the queue is regarded as a low-risk queue, so that the traffic originally entering the queue can be forwarded normally, and the network can enter a normal forwarding flow.
In this embodiment, for a transmission path that does not include the first traffic, the traffic packet loss risk of the buffer queue with a buffer ratio exceeding 90% is generally regarded as a high risk, and when the high risk is detected, a warning is sent to the user to prevent the traffic packet loss in the current queue; the flow packet loss risk of the buffer queue with the buffer proportion lower than 10% is regarded as low risk, when the low risk is detected, the buffer of the port is adjusted to half of the maximum value, forwarding memory can be saved for the OVS to use the computing resource, and the buffer can be saved for the physical exchanger to forward for other ports, so that the service efficiency of the whole network system is improved.
As shown in fig. 4, in one embodiment, a cloud network traffic forwarding apparatus includes:
the confirmation module 410 is configured to confirm a transmission path of a first traffic, where the first traffic is a traffic with a transmission priority higher than a first threshold.
Specifically, the user classifies the traffic according to the importance degree of the traffic, wherein the first traffic is of a traffic type needing lossless forwarding, so that the transmission priority of the first traffic is set to be higher than a first threshold. For example, the user considers that the flow of accessing the object storage and the file storage by the virtual machine is important, and the flow can be set to be the first flow, so that the possibility of packet loss is reduced to the greatest extent in the transmission process. And finding out a transmission path of the service flow according to the flow type set by the user, and further finding out a starting point in the transmission path and switch equipment of each node. Wherein the switch device comprises an OVS (virtual switch) and a physical switch.

Specifically, the transmission path is monitored, when the buffer ratio of the buffer queue where the first flow is located exceeds a third threshold, the risk of congestion packet loss occurring in the buffer queue is considered to be larger, and the DSCP (differential service code point) values of the outer layer Vxlan (extensible virtual local area network) head and the inner layer IP packet head of the first flow in the buffer queue are set to be the highest, so that the first flow can enter the buffer queue preferentially, the number of packets sent by the buffer queue is reduced, the second flow entering the buffer queue is reduced, and the buffer ratio in the buffer queue is reduced. The transmission priority of the second flow is lower than that of the first flow, and lossless forwarding is not needed; the buffer ratio is the ratio of the buffer capacity of the exchanger equipment occupied by all traffic in the path.
