Packet loss occurs when one or more packets of data travelling across a computer network fail to reach their destination. Packet loss is either caused by errors in data transmission, typically across wireless networks, [1] [2] or network congestion. [3]: 36 Packet loss is measured as a percentage of packets lost with respect to packets sent.
Such services include digital voice calls (VOIP), online gaming, video chat, and other interactive applications such as radio streaming, video on demand, and remote login. When the bufferbloat phenomenon is present and the network is under load, even normal web page loads can take many seconds to complete, or simple DNS queries can fail due to ...
Streaming media refers to multimedia delivered through a network for playback using a media player.Media is transferred in a stream of packets from a server to a client and is rendered in real-time; [1] this contrasts with file downloading, a process in which the end-user obtains an entire media file before consuming the content.
Unlike a local game where the inputs of all players are executed instantly in the same simulation or instance of the game, in an online game there are several parallel simulations (one for each player) where the inputs from their respective players are received instantly, while the inputs for the same frame from other players arrive with a certain delay (greater or lesser depending on the ...
For the cloud gaming experience to be acceptable, the round-trip lag of all elements of the cloud gaming system (the thin client, the Internet and/or LAN connection the game server, the game execution on the game server, the video and audio compression and decompression, and the display of the video on a display device) must be low enough that ...
The follow-on priority-based flow control, as defined in the IEEE 802.1Qbb standard, provides a link-level flow control mechanism that can be controlled independently for each class of service (CoS), as defined by IEEE P802.1p and is applicable to data center bridging (DCB) networks, and to allow for prioritization of voice over IP (VoIP ...

There are two principal approaches to QoS in modern packet-switched IP networks, a parameterized system based on an exchange of application requirements with the network, and a prioritized system where each packet identifies a desired service level to the network. Integrated services ("IntServ") implements the parameterized approach.
