Path MTU Discovery Wikipedia ~ 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

Maximum transmission unit Wikipedia ~ 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 The MTU relates to but is not identical to the maximum frame size that can be transported on the data link layer Ethernet frame Larger MTU is associated with reduced overhead

Black hole networking Wikipedia ~ A DNSbased Blackhole List DNSBL or Realtime Blackhole List RBL is a list of IP addresses published through the Internet Domain Name System DNS either as a zone file that can be used by DNS server software or as a live DNS zone that can be queried in realtime DNSBLs are most often used to publish the addresses of computers or networks linked to spamming most mail server software can

Jumbo frame Wikipedia ~ In computer networking jumbo frames are Ethernet frames with more than 1500 bytes of payload the limit set by the IEEE 8023 standard Conventionally jumbo frames can carry up to 9000 bytes of payload but variations exist and some care must be taken using the term Many Gigabit Ethernet switches and Gigabit Ethernet network interface cards can support jumbo frames

Internet Control Message Protocol Wikipedia ~ Technical details ICMP is part of the Internet protocol suite as defined in RFC messages are typically used for diagnostic or control purposes or generated in response to errors in IP operations as specified in RFC 1122ICMP errors are directed to the source IP address of the originating packet

Stream Control Transmission Protocol Wikipedia ~ The Stream Control Transmission Protocol SCTP is a computer networking communications protocol which operates at the transport layer and serves a role similar to the popular protocols TCP and UDP It is standardized by IETF in RFC 4960

Maximum segment size Wikipedia ~ 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

IPv6 Wikipedia ~ IPv6 hosts are required to either perform path MTU discovery perform endtoend fragmentation or to send packets no larger than the default Maximum transmission unit MTU which is 1280 octets Mobility Unlike mobile IPv4 mobile IPv6 avoids triangular routing and is therefore as efficient as native IPv6 IPv6 routers may also allow entire

TalkMaximum segment size Wikipedia ~ PMTU is an algorithmtechnique that is used to dynamically determine the maxmum usable MTU for a link It does seem to me also that one article with a couple of links could probably handle all three concepts
