====== Bandwidth ====== The amount of data you can squeeze through a connection is often titled "bandwidth". You can test network bandwidth with [[:guide:iperf|iperf]]. ===== Common real life connection speed ===== Here's a list of select link speeds in bit/s and byte/s for comparison. The table contains estimates of real life net data rates, not the theoretical maximum data rate. Units: * b = bit * B = byte * 1Kb = 1000 bit * 1KB = 1000Byte * 1KiB[(many people incorrectly assume that a Kilobyte is 1024 Byte, instead that'd be a [[https://en.wikipedia.org/wiki/Kibibyte|Kibibyte]])] = 1kB = 1024 Byte. * 1MB/s = 1E6[(1E6 in scientific/engineering notation means 1·106 = 1 000 000)] byte per second ^ Technology ^ bit/s ^ byte/s | | USB2 | | 33MiB | | USB3 | | | | GbE | | | | 10 GbE | | | | SMBv2 | | | | SATA 6G | | | ===== Common applications ===== If the bandwidth needed is not symmetrical, ↓ means downstream (server→client) and ↑ means upstream (client→server). This is always per User. ^ Application ^ Protocol/setting ^ bit/s ^ Packets/s | | VoIP | G.711 | 87.2Kb[(Source: [[https://www.cisco.com/c/en/us/support/docs/voice/voice-quality/7934-bwidth-consume.html|Cisco Docs "Voice Over IP - Per Call Bandwidth Consumption"]])] | | | ::: | G.729 | 31.2Kb | | | ::: | TeamSpeak (10 people) | ↓25.9Kb ↑233Kb[(Source: [[https://support.teamspeak.com/hc/en-us/articles/360002710657-How-much-bandwidth-does-TeamSpeak-require-|support.teamspeak.com]])] | | | Netflix | SD Quality (480p) | | | ::: | Full HD (1080p) | ↓5Mb | | | ::: | Ultra HD (4K) | ↓25Mb | | ==== Gaming bandwidth ==== ^ Platform ^ Game ^ bit/s ^ Packets/s | | PS4 | Battlefield 4 | ↓150Kb[(Source: [[https://gobrolly.com/amount-data-bandwidth-required-video-gaming/|gobrolly.com – Data and Bandwidth Required For Video Gaming]])] | | | PC | Counter-Strike: Global Offensive | | |
