ULTRA-LOW LATENCY SWITCHING APPARATUS AND A CASCADING METHOD THEREOF

原文（中国語）

An ultra-low latency switching apparatus and a cascading method thereof are provided. In the method, one first enhanced signal port located at a Media Access Control, MAC, unit is allocated to a unidirectional forwarding port group of a switching hardware unit; the unidirectional forwarding port group comprises one first port serving as a source port and one or more second ports serving as destination ports. a first inter-chip link is established from the first port to the first enhanced signal port and reaches the second ports through an internal loopback of the first enhanced signal port; pre-emphasis transmission parameters for each of the second ports are set.
