Used as a filler to guarantee that the data starts on a 32 bit boundary.
(RFC 1242: 3.1) Fixed length frames presented at a rate such that there is the minimum legal separation for a given medium between frames over a short to medium period of time, starting from an idle state.
(RFC 1242: 3.3) A network device that can selectively function as a router and/or a bridge based on the protocol of a specific frame.
(RFC 1242: 3.4) Fixed length frames at a fixed interval time.
Data link frame size.
(RFC 1242: 3.5) The number of bytes in the frame from the first byte following the preamble to the end of the FCS, if present, or to the last octet of the data if there is no FCS.
(RFC 3140) Differentiated Services introduces the notion of Per Hop Behaviors (PHBs) that define how traffic belonging to a particular behavior aggregate is treated at an individual network node. In IP packet headers, PHBs are not indicated as such; instead Differentiated Services Codepoint (DSCP) values are used. There are only 64 possible DSCP values, but there is no such limit on the number of PHBs. In a given network domain, there is a locally defined mapping between DSCP values and PHBs. Standardized PHBs recommend a DSCP mapping, but network operators may choose alternative mappings.
(RFC 2344: 1.1) A tunnel that shuttles packets towards the mobile node. It starts at the home agent, and ends at the mobile node's care-of address.
Frame loss rate.
(RFC 1242: 3.6) Percentage of frames that should have been forwarded by a network device under steady state (constant) load that were not forwarded due to lack of resources.
Inter Frame Gap.
(RFC 1242: 3.7) The delay from the end of a data link frame to the start of the preamble of the next data link frame.
IPv4 internet address.

|C||1||1||0||Network bits||Host bits|
Internet address block allocation.
|0.0.0.0/8||Addresses in this block refer to source hosts on "this" network. Address 0.0.0.0/32 may be used as a source address for this host on this network; other addresses within 0.0.0.0/8 may be used to refer to specified hosts on this network.|
|10.0.0.0/8||Private use networks. Addresses within this block should not appear on the public Internet.|
|184.108.40.206/8||Public Data Networks.|
|220.127.116.11/8||Cable television networks provisioning.|
|18.104.22.168/8||This block was used in the "Class A Subnet Experiment" that commenced in May 1995. The experiment has been completed and this block has been returned to the pool of addresses reserved for future allocation or assignment. This block therefore no longer has a special use and is subject to allocation to a Regional Internet Registry for assignment in the normal manner.|
|127.0.0.0/8||Loopback. A datagram sent by a higher level protocol to an address anywhere within this block should loop back inside the host. This is ordinarily implemented using only 127.0.0.1/32 for loopback, but no addresses within this block should ever appear on any network anywhere.|
|22.214.171.124/16||This block, corresponding to the numerically lowest of the former Class B addresses, was initially and is still reserved by the IANA. Given the present classless nature of the IP address space, the basis for the reservation no longer applies and addresses in this block are subject to future allocation to a Regional Internet Registry for assignment in the normal manner.|
|169.254.0.0/16||Link Local. It is allocated for communication between hosts on a single link. Hosts obtain these addresses by autoconfiguration, such as when a DHCP server may not be found.|
|172.16.0.0/12||Private use networks. Addresses within this block should not appear on the public Internet.|
|126.96.36.199/16||This block, corresponding to the numerically highest to the former Class B addresses, was initially and is still reserved by the IANA. Given the present classless nature of the IP address space, the basis for the reservation no longer applies and addresses in this block are subject to future allocation to a Regional Internet Registry for assignment in the normal manner.|
|192.0.0.0/24||This block, corresponding to the numerically lowest of the former Class C addresses, was initially and is still reserved by the IANA. Given the present classless nature of the IP address space, the basis for the reservation no longer applies and addresses in this block are subject to future allocation to a Regional Internet Registry for assignment in the normal manner.|
|192.0.2.0/24||Test-Net. It is often used in conjunction with domain names example.com or example.net in vendor and protocol documentation. Addresses within this block should not appear on the public Internet.|
|188.8.131.52/24||6to4 relay anycast.|
|192.168.0.0/16||Private use networks. Addresses within this block should not appear on the public Internet.|
|198.18.0.0/15||Network interconnect device benchmark testing.|
|184.108.40.206/24||This block, corresponding to the numerically highest of the former Class C addresses, was initially and is still reserved by the IANA. Given the present classless nature of the IP address space, the basis for the reservation no longer applies and addresses in this block are subject to future allocation to a Regional Internet Registry for assignment in the normal manner.|
|220.127.116.11/4||Multicast. Formerly known as the Class D address space, it is allocated for use in IPv4 multicast address assignments.|
|240.0.0.0/4||This block, formerly known as the Class E address space, is reserved. The "limited broadcast" destination address 255.255.255.255 should never be forwarded outside the (sub-)net of the source. The remainder of this space is reserved for future use.|
The data header and message that are transmitted between internet hosts.
A part of the data message with intact header fields.
(RFC 1242: 3.8) For store and forward devices: The time interval starting when the last bit of the input frame reaches the input port and ending when the first bit of the output frame is seen on the output port. For bit forwarding devices: The time interval starting when the end of the first bit of the input frame reaches the input port and ending when the start of the first bit of the output frame is seen on the output port.
Link Speed Mismatch.
(RFC 1242: 3.9) Speed mismatch between input and output data rates.
A node with multiple IP addresses.
MTU, Maximum Transmission Unit.
The MTU of the output network is smaller than the MTU of the input network. This results in packet fragmentation.
(RFC 1242: 3.11) Processing done other than that for normal data frames.
(RFC 1242: 3.12) When demand exceeds available system resources.
Policy based filtering.
(RFC 1242: 3.13) The process of discarding received frames by administrative decision where normal operation would be to forward them.
(RFC 1242: 3.14) Reinitialization of system causing data loss.
(RFC 2344: 1.1) A tunnel that starts at the mobile node's care-of address and terminates at the home agent.
An algorithm for moving frames between connected networks.
Single frame behavior.
(RFC 1242: 3.16) One frame received on the input to a device.
(RFC 1242: 3.17) The maximum rate at which none of the offered frames are dropped by the device.
