bit 5: device supports pause frame; bit 6: device supports asymmetric pause for full duplex; bit 7: reserved; The link code words are also called pages. The base link code word is therefore called a base page. The next page bit of the base page is 1 when the device intends to send other pages, which can be used to communicate other abilities.
In IEEE 802 networks such as Ethernet or IEEE 802.11, each frame includes a destination MAC address. In non-promiscuous mode, when a NIC receives a frame, it drops it unless the frame is addressed to that NIC's MAC address or is a broadcast or multicast addressed frame. In promiscuous mode, however, the NIC allows all frames through, thus ...
Time-Sensitive Networking ( TSN) is a set of standards under development by the Time-Sensitive Networking task group of the IEEE 802.1 working group. [1] The TSN task group was formed in November 2012 by renaming the existing Audio Video Bridging Task Group [2] and continuing its work. The name changed as a result of the extension of the ...
Ethernet flow control. Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks. The goal of this mechanism is to avoid packet loss in the presence of network congestion . The first flow control mechanism, the pause frame, was defined by the IEEE 802.3x standard.
This frame may cause a collision at the remote end which cannot be detected by the transmitter, so the frame is not resent on the physical layer. Due to interference on the medium, its data is corrupted and frame check sequence fails, requiring recovery at a higher layer, if possible. [citation needed] Channel capture effect
The total time considers the round trip time along the channel, the processing time in the hosts and the time transmitting data and acknowledgements. The time spent transmitting data includes data and acknowledgements. Runt frames. A runt frame is an Ethernet frame that is less than the IEEE 802.3's minimum length of 64 octets.
Duplex mismatch. On an Ethernet connection, a duplex mismatch is a condition where two connected devices operate in different duplex modes, that is, one operates in half duplex while the other one operates in full duplex. The effect of a duplex mismatch is a link that operates inefficiently. Duplex mismatch may be caused by manually setting two ...
Flow control (data) In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver. Flow control should be distinguished from congestion control, which is used for controlling the flow of data when congestion has actually occurred. [1]
