When the number of ports that a single switch can provide is insufficient to meet the requirements of the network computer, more than two switches must provide the corresponding number of ports, which also involves the connection between switches. Basically, there are two ways to connect vswitches: Stack and cascade.

When a function call occurs in a program, the computer does the following: First, the parameters are pressed into the stack;The contents of the Save instruction Register (IP) are returned address (RET); The third is the base address that is sent to the stack(FP), then copy the current stack pointer (SP) to the FP as the new base address, and finally the localAmount of space, the SP minus the appropriate value. Take the following procedure as an example:

GE switches are still commonly used. So I have studied the full performance solution of the mainstream L2 switches with all-optical ports. I would like to share this with you and hope it will be useful to you. Recently, the F-engine S2200F series all-optical ports, 10-Gigabit L2 switches and F-engine S2200G series all-optical ports, which are independently developed by beacon network, were officially introduced to the market, this is an important step in improving the Ethernet switch Product Lin
