分布式快速端口扫描的任务调度算法与协议研究

Task Scheduling Algorithm and Protocol for Distributed Rapid Port Scanning

随着端口扫描技术的发展,一些如ZMap、MASSCAN等的单节点快速端口扫描工具相继被提出,从而最大限度地利用带宽资源进行端口扫描。然而,这些工具的性能受制于单节点的带宽,提升空间较为有限。为了进一步提升这些工具的性能,提出了一种分布式任务调度算法及其配套协议,可用于实现一套分布式的快速端口扫描系统。该算法将目标地址进行分片后,下发给所有可用的扫描节点同时进行端口扫描,理论上能够利用所有节点的带宽资源。此外,该算法还具备一些异常处理机制,用于保证系统的可用性和结果的准确性。

With the development of port scanning technology,some fast single-node port scanning tools,such as ZMap and MASSCAN,are proposed to maximize the use of bandwidth resources for port scanning.However,the performance of these tools is limited by the bandwidth of a single node.In order to further improve the performance of these tools,a distributed task scheduling algorithm and its supporting protocol is proposed,which can be used to implement a rapid distributed port scanning system.With the addresses sharding technology,the target address can be sent to all available nodes for simultaneous port-scanning,and this could theoretically utilize the bandwidth resources of all nodes.In addition,the algorithm also has some exception handling mechanisms,and these mechanisms maybe used to ensure the availability of the system and the accuracy of the results.
