Multi-scale converged network simulation task mapping method under heterogeneous environment

Abstract

The invention discloses a multi-scale converged network simulation task mapping method under heterogeneous environment. The deployment problem of a virtual network topology under the heterogeneous computing cluster environment is solved. The method comprises the following steps: reading in the heterogeneous computing environment; marking an edge router and a host node in the topology as a lightweight virtual mapping area, and marking the rest nodes as a converged virtual mapping area; mapping the node in the lightweight virtual mapping area by using the lightweight virtual mapping according toa throughput threshold of each server; computing a load balance parameter of each rest server, distributing nodes in a converged mapping region by adopting a multilevel scheme division algorithm, judging whether the server is redundant, and performing the optimization by adopting different optimization algorithms according to the result, and performing the reasonable mapping. Through the method disclosed by the invention, the load balance between the computing clusters can be guaranteed, and the remote communication is reduced, and the large-scale network simulation performance is improved; meanwhile, the good extensibility and scalability are provided for the large-scale network topology, and the method can be used for various network researches and experiment networks.

Docker routers and KVM routers have their own advantages and disadvantages. Generally speaking, KVM has high throughput, short delay, and stable performance. Therefore, the number of KVM routers that can be started by a computing node is small; while the DOCKER router starts quickly and is not limited by the memory size and the number of CPUs. Thousands of DOCKER routers can run on a high-performance computing node at the same time, and In the case of multiple Dockers working, it can achieve load balancing, but the performance is affected by the number of startups, and the throughput is small and the delay is slightly longer.
