Dynamic monitoring model based on DPDK parallel communication

为了更好地发挥通信系统的性能,充分利用系统节点的资源,提高系统的可靠性与稳定性,设计了一种基于DPDK并行通信的动态监控模型。该模型结合DPDK和通信系统的高速率、大流量、强实时性等特点,面向多节点备份、数据包与控制包分离、多网口并行收发数据包、多核并行处理数据包进行设计,分析了监控对象,研究了数据采集方法,设计了二层通信协议DMPD,并对网口进行了细粒度监控,给出了网口负载信息模型。另外,将散列函数、调整函数与动态负载信息结合起来设计了更有效、更公平的基于多网口的动态负载均衡算法。实验结果表明,该监控模型能够准确检测和及时处理系统出现的异常,并且实现了多网口的动态负载均衡。

In order to make better use of the performance of communication system,make full use of the resources of system nodes,and improve the reliability and stability of the system,a dynamic monitoring model based on DPDK(Data Plane Development Kit)parallel communication was designed.Combined with the high speed,large traffic,strong real-time characteristics of DPDK and communication system,the model was designed for multi-node backup,data packet and control packet separation,transmitting and receiving data packets in parallel by multiple network ports,and processing data packets in parallel by multiple cores.The monitoring objects were analyzed,the data acquisition methods were researched,and a 2-layer communication protocol named DMPD was designed.The fine-grained monitoring was performed on the network ports,and the network port load information model was given.Besides,a more efficient and fair dynamic load balancing algorithm based on multi-network port was designed by combining hash function,adjustment function and dynamic load information.Experimental results show that the dynamic monitoring model can accurately detect and timely deal with the abnormality appeared in the system,and achieve the load balancing of multiple network ports.
