Switching Capacity

The switching capacity of the switch, also known as the backplane bandwidth or switching bandwidth, is the maximum amount of data that can be handled between the switch interface processor or interface card and the data bus. The exchange capacity indicates the total data exchange capacity of the switch, and the unit is Gbps. The exchange capacity of a general switch ranges from several Gbps to hundreds of Gbps. The higher the switching capacity of a switch, the stronger the ability to process data, but the higher the design cost.

 Packet forwarding Rate

The packet forwarding rate of the switch indicates the size of the switch’s ability to forward packets. The unit is generally bps, and the packet forwarding rate of general switches ranges from tens of Kpps to hundreds of Mpps. The packet forwarding rate refers to how many million data packets (Mpps) the switch can forward per second, that is, the number of data packets that the switch can forward at the same time. The packet forwarding rate reflects the switching capability of the switch in units of data packets.

In fact, an important indicator that determines the packet forwarding rate is the backplane bandwidth of the switch. The higher the backplane bandwidth of a switch, the stronger the ability to process data, that is, the higher the packet forwarding rate.

Ethernet Ring

An Ethernet ring (commonly known as a ring network) is a ring topology consisting of a group of IEEE 802.1 compliant Ethernet nodes, each node communicating with the other two nodes through an 802.3 Media Access Control (MAC) based ring port The Ethernet MAC can be carried by other service layer technologies (such as SDHVC, Ethernet pseudowire of MPLS, etc.), and all nodes can communicate directly or indirectly.
