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.
