AI Technical Summary

Technical Problem

The complex and dynamic nature of home network environments can lead to network connectivity issues for devices under the PCDN architecture, making content distribution impossible.

Method used

By obtaining the local address and the port to be tested, a port probe request is sent, a reverse probe request is detected, and available ports are dynamically detected. Within a set time, an available port is determined for content distribution.

Benefits of technology

In complex or dynamically changing network environments, the system dynamically detects available ports to ensure efficient content distribution and avoid issues caused by fixed ports becoming unusable.

Abstract

本申请涉及通信技术领域，提供一种通信端口探测方法、装置、设备及存储介质。该方法包括：获取本机地址及第一待测端口的端口信息；根据本机地址和每个第一待测端口的端口信息确定针对每个第一待测端口的端口探测请求，并将针对每个第一待测端口的端口探测请求由客户端发送给服务端；检测客户端在设定时间内是否接收到服务端通过每个第一待测端口发送的反向探测请求；若客户端在设定时间内接收到服务端通过第一待测端口中的目标端口发送的反向探测请求，则将目标端口确定为可用端口；可用端口用于使客户端对应的网络设备在当前时间通过可用端口与同一网络下的其他设备进行内容分发。采用本申请技术方案可实时探测出可用端口来实现内容分发。
