Mastering Ethernet Switch Memory Buffering: Techniques for 2025 Networks

Ethernet switches employ memory buffering to manage data traffic efficiently, ensuring frames (data units) are temporarily stored when destination ports face congestion. Effective buffering is crucial to prevent frame loss, which can degrade network performance, increase latency, and trigger retransmissions, ultimately impacting user experience and reliability. This article explores buffering methods, their evolution, and their...

Switching Fundamentals – Everything to Know

An Ethernet switch is a Layer 2 device. Therefore, the switch uses MAC addresses for switching decisions. It is unaware of the protocol being carried in the data portion of the frame, such as an IPv4 packet. The Ethernet hub repeats bits out of all ports except the incoming port, but an Ethernet switch consults...
