  2. Maximum transmission unit - Wikipedia

    en.wikipedia.org/wiki/Maximum_transmission_unit

    With the normal untagged Ethernet frame overhead of 18 bytes and the 1500-byte payload, the Ethernet maximum frame size is 1518 bytes. If a 1500-byte IP packet is to be carried over a tagged Ethernet connection, the Ethernet frame maximum size needs to be 1522 bytes due to the larger size of an 802.1Q tagged frame.

  3. EtherType - Wikipedia

    en.wikipedia.org/wiki/EtherType

    EtherType is a two-octet field in an Ethernet frame.It is used to indicate which protocol is encapsulated in the payload of the frame and is used at the receiving end by the data link layer to determine how the payload is processed.

  4. IP fragmentation - Wikipedia

    en.wikipedia.org/wiki/IP_fragmentation

    An example of the fragmentation of a protocol data unit in a given layer into smaller fragments. IP fragmentation is an Internet Protocol (IP) process that breaks packets into smaller pieces (fragments), so that the resulting pieces can pass through a link with a smaller maximum transmission unit (MTU) than the original packet size.

  5. Path MTU Discovery - Wikipedia

    en.wikipedia.org/wiki/Path_MTU_Discovery

    The process is repeated until the MTU is small enough to traverse the entire path without fragmentation. As IPv6 routers do not fragment packets, there is no Don't Fragment option in the IPv6 header. For IPv6, Path MTU Discovery works by initially assuming the path MTU is the same as the MTU on the link layer interface where the traffic originates.

  6. Jumbo frame - Wikipedia

    en.wikipedia.org/wiki/Jumbo_frame

    Jumbo frames have payloads greater than 1500 bytes. In computer networking , jumbo frames are Ethernet frames with more than 1500 bytes of payload, the limit set by the IEEE 802.3 standard. [ 1 ] The payload limit for jumbo frames is variable: while 9000 bytes is the most commonly used limit, smaller and larger limits exist.

  7. Maximum segment size - Wikipedia

    en.wikipedia.org/wiki/Maximum_segment_size

    The maximum segment size (MSS) is a parameter of the Options field of the TCP header that specifies the largest amount of data, specified in bytes, that a computer or communications device can receive in a single TCP segment. It does not count the TCP header or the IP header (unlike, for example, the MTU for IP datagrams).

  8. List of interface bit rates - Wikipedia

    en.wikipedia.org/wiki/List_of_interface_bit_rates

    On devices like modems, bytes may be more than 8 bits long because they may be individually padded out with additional start and stop bits; the figures below will reflect this. Where channels use line codes (such as Ethernet , Serial ATA , and PCI Express ), quoted rates are for the decoded signal.

  9. Measuring network throughput - Wikipedia

    en.wikipedia.org/wiki/Measuring_network_throughput

    Each cell is 53 bytes long, with the first 5 bytes defined as the header, and the following 48 bytes as payload. Data networking commonly requires packets of data that are larger than 48 bytes, so there is a defined adaptation process that specifies how larger packets of data should be divided up in a standard manner to be carried by the ...
