Upstream is how fast a host(user) internet server sends data to the network. Ex When one plays a game ( hitting buttons etc) or types data in on the pc, that persons is sending data to the network. The network process this data at a certain speed. So how fast ones Internet service provider (ISP) sends a host(user) 's data to the network is called upstream and how fast the network send data to the ISP then to the host is called downstream.
No, asymmetric connections do not require the same bandwidth for each direction. In asymmetric connections, the bandwidth is usually allocated unequally between the upstream (upload) and downstream (download) directions. This is common in DSL, cable, and satellite internet connections.
Cable systems provide rates of approximately 500 Kbps downstream and 128 Kbps upstream. Theoretically they can provide a bandwidth of 30 Mbps. A DSL system can provide speeds of up to 7.1 Mbps, but most providers offer a maximum of 1.5 Mbps upstream and downstream.
ADSL modems carry high bandwidth traffic by using a technique called frequency division multiplexing. This allows the modem to split the available bandwidth into separate channels: one for upstream data and multiple for downstream data. By utilizing higher frequency ranges for downstream traffic, ADSL can achieve faster speeds while still allowing voice signals to be transmitted simultaneously over the same phone line. This efficient use of the existing copper infrastructure enables high data rates without requiring significant upgrades.
Heres how you calculate required bandwidth: If 100 people want to download a 15 MB file from your server then: 100 people * 15 MB = 1,500 MB = 1.5 GB (1GB=1000MB) So you need 1.5 GB downstream bandwidth. If you expect 100 people per day to download the file, then for a 31-day month, you'll need 45 GB downstream bandwidth, since bandwidth is usually advertised as the number of GB per month. So if you have 15 people that want to download a 2MB image and 10 people that want to download a 3MB sound file, then: (15 people * 2 MB) + (10 people * 3 MB) = 60 MB = .06 GB -DJ Craig

ADSL (Asymmetric Digital Subscriber Line) divides the bandwidth of a twisted pair cable using frequency division multiplexing. It allocates lower frequencies for voice calls, allowing traditional telephone services to operate simultaneously with internet data. Higher frequencies are reserved for upstream and downstream data transmission, with downstream speeds typically being greater than upstream speeds, hence the term "asymmetric." This separation enables efficient use of the same line for both voice and data services without interference.
Downstream
the boat is going downstream.
LAN Bandwidth is the bandwidth (Maximum speed) of the Local Area Network
