  2. Upstream (networking) - Wikipedia

    en.wikipedia.org/wiki/Upstream_(networking)

    Symmetric connections such as Symmetric Digital Subscriber Line (SDSL) and T1, however, offer identical upstream and downstream rates. If a node A on the Internet is closer (fewer hops away) to the Internet backbone than a node B, then A is said to be upstream of B or conversely, B is downstream of A. Related to this is the idea of upstream ...

  3. List of interface bit rates - Wikipedia

    en.wikipedia.org/wiki/List_of_interface_bit_rates

    This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels.

  4. G.992.1 - Wikipedia

    en.wikipedia.org/wiki/G.992.1

    If bit swapping is disabled then this does not happen and the modem needs to retrain in order to adapt to changing line conditions. There are 2 competing standards for DMT ADSL - ANSI and G.dmt; ANSI T1.413 is a North American standard, G.992.1 (G.dmt) is an ITU (United Nations Telecom committee) standard.

  5. G.992.5 Annex M - Wikipedia

    en.wikipedia.org/wiki/G.992.5_Annex_M

    This specification extends the capability of commonly deployed Annex A by more than doubling the number of upstream bits. The data rates can be as high as 12 or 24 Mbit/s downstream and 3 Mbit/s upstream depending on the distance from the DSLAM to the customer's premises. [1] [2] Frequency plan for common ADSL standards and annexes.

  6. Digital subscriber line - Wikipedia

    en.wikipedia.org/wiki/Digital_subscriber_line

    In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology, for Internet access. In ADSL, the data throughput in the upstream direction (the direction to the service provider) is lower, hence the designation of asymmetric service.

  7. ADSL - Wikipedia

    en.wikipedia.org/wiki/ADSL

    The telephone exchange can indicate a suggested SNR margin to the customer's DSL modem when it initially connects, and the modem may make its bits-per-bin allocation plan accordingly. A high SNR margin will mean a reduced maximum throughput, but greater reliability and stability of the connection.

  8. Network throughput - Wikipedia

    en.wikipedia.org/wiki/Network_throughput

    For example, a gateway router supporting a populated class B subnet, handling 10 × 100 Mbit/s Ethernet channels, must examine 16 bits of address to determine the destination port for each packet. This translates into 81913 packets per second (assuming maximum data payload per packet) with a table of 2^16 addresses this requires the router to ...

  9. Network address translation - Wikipedia

    en.wikipedia.org/wiki/Network_address_translation

    If a packet is sent to 203.0.113.1 by a computer at 192.168.1.100, the packet would normally be routed to the default gateway (the router) [e] A router with the NAT loopback feature detects that 203.0.113.1 is the address of its WAN interface, and treats the packet as if coming from that interface. It determines the destination for that packet ...
