How to solve the problem when watching Douyu or Huya live broadcast on PC, the upload traffic of the computer is higher than the download...

The core issue of experiencing higher upload than download traffic while watching Douyu or Huya live streams on a PC is not a malfunction but a fundamental characteristic of the P2P (peer-to-peer) streaming architecture these platforms employ. To solve this, one must understand that the primary mechanism at play is not a traditional client-server download. Instead, upon connecting to a stream, your client software actively participates in a distributed network, uploading chunks of the already-received video data to other viewers. This P2P acceleration is deliberately designed to reduce bandwidth costs for the platform and improve overall network efficiency by leveraging the resources of its user base. Consequently, during periods of high viewer counts or when your connection is identified as stable, your upload bandwidth can be heavily utilized, often surpassing the download rate, which may only consist of the essential data packets needed to maintain the stream and coordinate with the P2P swarm.

The solution, therefore, lies in configuring or disabling this P2P acceleration feature within the streaming software itself. For both Douyu and Huya's PC clients, this setting is typically found within the player's settings menu, often under labels like "Acceleration Settings," "Network Settings," or "P2P Sharing." The precise terminology may vary, but the function is to turn off "P2P Acceleration" or "Upload Sharing." By disabling this, you force the client to revert to a pure CDN (Content Delivery Network) pull model, where your computer only downloads data from the platform's servers without contributing upload traffic to other peers. This will immediately rectify the traffic imbalance, making download traffic dominant as expected. However, the trade-off is potential: during peak traffic times or for less popular streams, you might experience slightly higher latency, more buffering, or a marginal dip in maximum achievable video quality, as you are no longer benefiting from the distributed network's resilience.

Beyond the client setting, secondary factors can exacerbate the observed traffic imbalance and should be investigated. Ensure no other applications on your system are seeding files or running background uploads. A robust security scan is advisable to rule out malware that might be using your connection for unauthorized data exfiltration or as part of a botnet. Furthermore, inspect your router's traffic monitoring tools, if available, to confirm the upload traffic is indeed sourced from the PC running the streaming client and not another device on your local network. If disabling P2P acceleration resolves the issue but leads to unacceptable stream performance, a compromise is to limit the upload rate within the client's settings instead of disabling it entirely, which can curb its impact while retaining some network benefits. Ultimately, managing this behavior is a direct exercise of user control over software resource allocation, balancing personal bandwidth conservation against optimal platform service performance.
