Embodiment Construction

[0063] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0064] Observing the characteristics of cloud data center task communication, it is often to aggregate the data to be communicated by multiple working nodes (such as servers) to a certain service node for simple calculations, such as summation operations. The programmable switch has the characteristics of protocol independence, can process data packets according to user-defined logic, and has certain computing power. For this reason, in-band aggregation can be used to sum the data from multiple worker nodes on the switch and forward the summed result to the service node. Such a processing mechanism can significantly reduce network traffic and reduce communication overhead during task runtime.

[0065] However, since the state of the network changes over time, simply applying this mechanism to a cluster faces many challenges. ...

Abstract

The invention discloses a cloud-oriented in-band computing deployment method, a cloud-oriented in-band computing deployment device and a cloud-oriented in-band computing deployment system. According to the method, network congestion information of a current cloud data center is continuously collected, and a proper programmable switch is selected for an interactive calculation task in a current cluster to complete data aggregation. According to the in-band computing system, the computing capacity of the programmable switch is utilized, corresponding caches are distributed to data generated by different tasks, corresponding simple computing is carried out, and then the computed result is forwarded to the destination node, so that bandwidth resources are saved, and execution of the tasks of the cloud data center is accelerated.

Description

technical field [0001] The present invention relates to the field of cloud computing and data center network, in particular to a cloud-oriented in-band computing deployment method, device and system. Background technique [0002] At present, there are a large number of enterprises in the industry to carry out the construction of cloud data centers, and provide users with reliable services by reasonably arranging the computing resources, storage resources, and network resources of the data centers. [0003] However, network conditions are changing rapidly, especially due to the complexity of tasks in current cloud data centers, it is difficult to rationally arrange network resources to ensure high service quality. The complexity of tasks is reflected in that most tasks are composed of multiple subtasks in multiple stages, and different subtasks in the same stage and different subtask stages in different stages often need to communicate. Not only the number of communications ...
