Notable examples are P2P for sharing files and Voice-over-IP (VoIP) for phone calls, made popular by Skype. In the late 1990s and early 2000s, other protocols has become popular while supporting a broader spectrum of services. The HTTP protocol has been the foundation of the World Wide Web, allowing the transfer of static content through the network. Year by year new services are born as the Internet connection becomes faster and more reliable for end users. PS Now instead uses only undocumented protocols and never exceeds 13 Mbit/s. They result bandwidth-hungry and consume up to 45 Mbit/s, depending on the network and video quality. We find that GeForce Now and Stadia use the RTP protocol to stream the multimedia content, with the latter relying on the standard WebRTC APIs. We analyze the employed protocols and the workload they impose on the network. We collect more than 200 packet traces under different application settings and network conditions for 3 cloud gaming services, namely Stadia from Google, GeForce Now from NVIDIA and PS Now from Sony. In this work, we study these new cloud gaming services from the network point of view. However, these companies released so far little information about their cloud gaming operation and how they utilize the network. Three among the leading tech companies, (Google, Sony and NVIDIA) entered this market with their own products, and others, like Microsoft and Amazon, are planning to launch their own platforms in the near future.

This service requires low latency and a large bandwidth to work properly with low response time and high-definition video. The multimedia content is streamed through the network from the server to the user.

It allows the user to play a videogame with basic equipment while using a remote server for the actual execution. Cloud gaming is a new class of services that promises to revolutionize the videogame market.
