2. Maximum transmission unit - Wikipedia

   en.wikipedia.org/wiki/Maximum_transmission_unit

   The IP MTU and Ethernet maximum frame size are configured separately. In Ethernet switch configuration, MTU may refer to Ethernet maximum frame size. In Ethernet-based routers, MTU normally refers to the IP MTU. If jumbo frames are allowed in a network, the IP MTU should also be adjusted upwards to take advantage of this.

3. Path MTU Discovery - Wikipedia

   en.wikipedia.org/wiki/Path_MTU_Discovery

   Path MTU Discovery (PMTUD) is a standardized technique in computer networking for determining the maximum transmission unit (MTU) size on the network path between two Internet Protocol (IP) hosts, usually with the goal of avoiding IP fragmentation. PMTUD was originally intended for routers in Internet Protocol Version 4 (IPv4). [1]

4. Jumbo frame - Wikipedia

   en.wikipedia.org/wiki/Jumbo_frame

   The frame size used by an end-to-end connection is typically limited by the lowest frame size in intermediate links. 802.5 Token Ring can support frames with a 4464-byte MTU, FDDI can transport 4352-byte, ATM 9180-byte and 802.11 can transport 7935-byte MTUs.

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. Metrics (networking) - Wikipedia

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

   Router metrics can contain any number of values that help the router determine the best route among multiple routes to a destination. A router metric is typically based on information like path length, bandwidth, load, hop count, path cost, delay, MTU, reliability and communications cost.

7. IPv6 packet - Wikipedia

   en.wikipedia.org/wiki/IPv6_packet

   Unlike in IPv4, IPv6 routers never fragment IPv6 packets. Packets exceeding the size of the maximum transmission unit (MTU) of the destination link are dropped and this condition is signaled by a Packet too big ICMPv6 message to the originating node, similarly to the IPv4 method when the Don't Fragment bit is set. [1]

8. 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.

9. 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 ...
