  2. Maximum transmission unit - Wikipedia

    en.wikipedia.org/wiki/Maximum_transmission_unit

    In computer networking, the maximum transmission unit (MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network layer transaction. [ 1 ] : 25 The MTU relates to, but is not identical to the maximum frame size that can be transported on the data link layer , e.g., Ethernet frame .

  3. Maximum segment size - Wikipedia

    en.wikipedia.org/wiki/Maximum_segment_size

    The default TCP Maximum Segment Size is for IPv4 is 536. For IPv6 it is 1220. [1]: §3.7.1 Where a host wishes to set the maximum segment size to a value other than the default, the maximum segment size is specified as a TCP option, initially in the TCP SYN packet during the TCP handshake. The value cannot be changed after the connection is ...

  4. Transmission Control Protocol - Wikipedia

    en.wikipedia.org/wiki/Transmission_Control_Protocol

    TCP was originally designed for wired networks where packet loss is considered to be the result of network congestion and the congestion window size is reduced dramatically as a precaution. However, wireless links are known to experience sporadic and usually temporary losses due to fading , shadowing, hand off, interference , and other radio ...

  5. Ethernet frame - Wikipedia

    en.wikipedia.org/wiki/Ethernet_frame

    The table below shows the complete Ethernet packet and the frame inside, as transmitted, for the payload size up to the MTU of 1500 octets. [ b ] Some implementations of Gigabit Ethernet and other higher-speed variants of Ethernet support larger frames, known as jumbo frames .

  6. Jumbo frame - Wikipedia

    en.wikipedia.org/wiki/Jumbo_frame

    In networking equipment, maximum jumbo frame size may be specified using either maximum frame size (maximum layer 2 packet size, includes frame headers) or maximum transmission unit (maximum layer 3 packet size, excludes frame headers), depending on the equipment's configuration interface. [citation needed]

  7. Internet Mix - Wikipedia

    en.wikipedia.org/wiki/Internet_Mix

    Network equipment that performs complex manipulation of packets, such as firewalls or VPN routers, often have non-wire rate performance and as such it can not deliver wire rate performance on small 64 byte packets, this is easier at 1500 byte packets - but none of these packet sizes resemble actual traffic seen on the Internet over some time.

  8. Measuring network throughput - Wikipedia

    en.wikipedia.org/wiki/Measuring_network_throughput

    where RWIN is the TCP Receive Window and RTT is the round-trip time for the path. The Max TCP Window size in the absence of TCP window scale option is 65,535 bytes. Example: Max Bandwidth = 65,535 bytes / 0.220 s = 297886.36 B/s * 8 = 2.383 Mbit/s. Over a single TCP connection between those endpoints, the tested bandwidth will be restricted to ...

  9. Network packet - Wikipedia

    en.wikipedia.org/wiki/Network_packet

    In telecommunications and computer networking, a network packet is a formatted unit of data carried by a packet-switched network. A packet consists of control information and user data; [ 1 ] the latter is also known as the payload .
