Super jumbo frames (SJFs) are frames that have a payload size over 9000 bytes. [21] As it has been a relatively difficult, and somewhat lengthy, process to increase the path MTU of high-performance national research and education networks from 1500 bytes to 9000 bytes or so, a subsequent increase, possibly to 64,000 bytes, is under consideration.
In packet-switched computer networks, a jumbogram (portmanteau of jumbo and datagram) is an internet-layer packet exceeding the standard maximum transmission unit (MTU) of the underlying network technology. In contrast, large packets for link-layer technologies are referred to as jumbo frames.
Nearly all IP over Ethernet implementations use the Ethernet II frame format. Ethernet with LLC and SNAP: 1492 [8] Ethernet jumbo frames: 1501–9202 [9] or more [10] The limit varies by vendor. For correct interoperation, frames should be no larger than the maximum frame size supported by any device on the network segment. [11] PPPoE v2: 1492 [12]
For comparison, Ethernet's protocol efficiency when using maximum throughput frames with payload of 1500 bytes is up to 95% and up to 99% with 9000 byte jumbo frames. However due to Ethernet's protocol overhead and minimum payload size of 42 bytes, if small messages of one or a few bytes are to be sent, Ethernet's protocol efficiency drops much ...
Pros and cons of a jumbo loan. Jumbo loans help you finance a large home purchase, however, you’ll pay more in interest over time than with a conforming loan. Here are some additional pros and cons:

The Federal Reserve announced another cut to its benchmark interest rates yesterday, dropping the Fed rate by 25 basis points to a range of 4.25% to 4.50% — the third consecutive time it's ...
IEEE 802.1Q, often referred to as Dot1q, is the networking standard that supports virtual local area networking (VLANs) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames.
