1.1 LAN Switching
1.1.7 Asymmetric switching
An asymmetric LAN switch provides switched connections between ports of unlike bandwidth, such as a combination of 10 Mbps and 100 Mbps ports. This type of switching is also called 10/100 switching. 

Asymmetric switching is optimized for client-server network traffic flows where multiple clients are simultaneously communicating with a server, requiring more bandwidth dedicated to the switch port that the server is connected to in order to prevent a bottleneck at that port.

Memory buffering in an asymmetric switch is required to allow traffic from the 100 Mbps port to be sent to a 10 Mbps port without causing too much congestion at the 10 Mbps port.
