Virtual node scheduling method and system for network simulation platform vlan interconnection

Abstract

The invention discloses a virtual node scheduling method and system for VLAN interconnection of a network simulation platform. The present invention first counts the sum of the resources requested to start the virtual nodes, and if there is a single physical host that can accommodate all virtual nodes, then it is scheduled to this physical host; otherwise, the total number of virtual nodes is selected to use the small topology map scheduling method or the large topology map scheduling method ; In the small-scale topology map scheduling method, the scheduling result with the fewest VLANs is obtained through the calculation method of conditional traversal. In the large-scale topology map scheduling method, the group scheduling method centered on key nodes is used to minimize the newly added VLANs during each group scheduling. . Multiple topology diagrams started at the same time can be combined and processed to achieve the least occupied VLAN. The invention solves the problem of reasonable utilization of VLAN resources on a multi-host network simulation platform, makes the distribution of the entire topology map on the physical host more compact, and the calculation process is simplified and intuitive.

Description

technical field [0001] The invention relates to a virtual node scheduling method and system based on VLAN interconnection of a multi-host network simulation platform, belonging to the field of network technology. Background technique [0002] Network emulation is a technology that simulates complex networks in reality through virtualization or network isolation. Network simulation platforms generally use virtual machines or containers to simulate nodes in the network, and use bridges or tunnels to simulate Layer 2 links between nodes. For small-scale network simulation experiments, only one physical host is needed; for large-scale network topology simulation or simultaneous simulation of multiple networks, the CPU, memory, and disk resources of a single physical host may not meet the requirements, so multiple Physical hosts form a cluster. The virtual nodes in a virtual network topology graph may be distributed on different physical hosts. [0003] We consider two virtual...

Problems solved by technology

Traditional virtual machine node scheduling methods usually only consider CPU, memory, disk, and bandwidth factors, ignoring the resource of VLAN numbers, which may affect the use of network simulation platforms
