Ethernet networks are broadcast networks established based on the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) mechanism. Collisions restrict Ethernet performance. Early Ethernet devices such as hubs work at the physical layer, and cannot confine collisions to a particular scope. This...
每个以太帧之间都要有帧间隙(Inter Frame Gap),即每发完一个帧后要等待一段时间才能再发另外一个帧,以便让帧接收者对接收的帧做必要的处理(如调整缓存的指针、更新计数、通知对报文进行处理等等)。在以太网标准中规定最小帧间隙是12个字节,其数据为全1。对于个别的接口,可减少到64(GE)或40比特(10GE),其他的...
Routersare used to pass packets between networks and use IP addresses rather than MAC addresses to tag packets' origination and destination points. Using the U.S. Postal Service as an analogy, IP addresses are like ZIP codes, while MAC addresses are like street addresses or post office boxes....
You donât need to know all the details of the frame and Ethernet system operation in order to build and use Ethernets. However, an understanding of these elements can certainly help when designing networks or troubleshooting problems. The original half-duplex mode Media Access Control ...
Ethernet is used to connect devices in a network and is still a popular form of network connection. Specific organizations with local networks, such as company offices, school campuses and hospitals, use Ethernet for its high speed, security and reliability. ...
and secure high-performance L2/L3 switching services. Huawei’s Ethernet switches have been widely used in Wide Area Network (WAN), MAN, and data center networks, building application-oriented network platforms for carriers and integrating switching and routing functions to build end-to-end converged...

Adapt to a changing world with Ethernet Connect for large business at BT Business. Offers flexible, cost-effective connectivity between business sites.
Ethernet has evolved dramatically since its first application and today is the de facto protocol for IP-based networks and the internet. Ethernet switches have also become the common network switch type and foundational technology for most networks. ...
The IEEE 802.2 logical link control standard is used for 802.3, 802.5, and other networks. The LLC sublayer provides connection-oriented or connectionless (acknowledged or not) services. The LLC can also multiplex different transmissions that are differentiated by the service access point field (see...
